What to do if the pump is stuck in the well? How can a stuck or fallen pump be pulled out of a well? How to get a baby out of a well.

During the operation of the source, it is often necessary to get pump equipment from the wellbore of the casing pipe. However, when carrying out this procedure, they often encounter a problem: the pump gets stuck in the well.

mine deposits;
sagging power cable;
siltation of the bottom of the source;
reverse siltation;
obstacles, got debris;
casing string deformation;
pump skew;
snagged on pipe joints.

Deposits in the well. The reason is the soil in which the casing is embedded. Limestone rocks in interaction with the metal body of the apparatus plus oxygen give a durable stone coating. Deposits can form both on the device itself and on the pipe walls at the location of the equipment. If, when lifting the device by the cable, there is no movement either up or down, and the cable and cable do not move when tensioned, this is a sure sign that there are salt deposits in the mine.
Sagging cable. The pump is held suspended in the pipe by a rope and a secure bolted connection. In addition, a hose or pipe and a power cable are attached to the device. Not infrequently, when pulling the device by the cable, we forget to pull out the cable in parallel, and after a few meters it sags and wraps around the pump housing. This can happen if the power cable was not attached to the rope with special clamps when the equipment was first immersed. It sagged during the operation of the well and wound around the device due to vibration. If, when trying to pull the device by the cable, it goes tight and constantly gets stuck, the reason is the cable sagging.
Silting of the bottom of the well. Casing pump set too deep after drilling and installation. Almost always, equipment gets stuck in the silt. There is a natural process of silt formation at the bottom in the pipe. In the first years of water consumption, the problem of silting will not be identified, because it comes clean and soil has not yet accumulated at the bottom. After prolonged use, the water from the apparatus may go with an admixture of liquid clay and change its color. This is a sure sign that he drowned in the mud.
Reverse silting. In addition to the accumulation of silt at the bottom of the source, there is the problem of completely blocking the body of the device inside the casing with silt. This happens due to the displacement of the seams in the joints, or due to improper installation of the casing. It also occurs in a mine on sandy soil, as sand and eroded soil enter the holes above the pump along with water. Gradually, the silt covers it completely and envelops it, preventing it from being pulled to the surface. If the cable in the taut state gradually moves, then up, then down, it means that the pump is bogged down in silt, and reverse silting has occurred in the well.
Got trash. There is little space in the water well, pumping equipment barely passes into it, however, during use, debris or a foreign object may get into the well for any reason. It is not always possible to keep track of the pipes. Children throw stones, toys, small animals and birds are found in the chimney (although this rarely happens). Foreign objects make it difficult to remove the pump from the well. Debris that gets into the barrel falls to the very bottom and rests against the pump. A clear sign of a foreign object getting into the shaft will be a characteristic snort and rattle when trying to pull the cable.
Casing string deformation. Incorrect installation, dishonest attitude to work lead to problems in the wellbore. Deep water-bearing pipes are assembled with a screw connection or a tongue-and-groove method. Therefore, there is a risk of detachment at the joints. This happens due to the negligence of workers, or because of the characteristics of the soil. Pipes move away from each other and stand upright. A shelf is formed in the trunk, and accordingly, the channel narrows. characteristic feature casing deformation - knocking and sudden stop when lifting.
Pump skew. The decision on the need to remove the device from the shaft has been made, and it's time to start pulling it out. But after several movements in the upward direction, it is stuck and does not move, which means that a skew has occurred. The reason is the rope or cable, which caught on the bottom of the equipment or the side connection when lifting, as a result, the device became a wedge.
The device caught on the joints of the pipe. In the process of lifting, he may have rested on butt joint. Determining the cause is quite simple. Average length metal pipe 6-8 meters, polyethylene - 4-6 meters. It is necessary to measure the appropriate length on the cable, when pulled out, it will become clear what the depth is and what seam the pump rested against.

Several ways to pull out the device

Salt and limestone deposits

Pull the cable several times without maximum effort, gradually moving the cable up and down like a fishing rod. If this does not help, there is another way - to break the deposits with a pneumatic impact. Quite an expensive method, but positive characteristics. Need powerful compressor and a long tube with a diameter of 15 mm. It is lowered to the level of the unit and attached to the compressor. Then a stream of air is fired into the body of the equipment or along the wall of the pipe. The shot should break the plaque and release the device.

cable slack

Cables are different. They are selected depending on the power of the unit. For stronger devices, a rigid reinforced cable is required. In case of sagging, it will not wrap around the body, but simply warp the device, which will make it impossible to lift it to the surface. It will be enough to pull out the cable along with the cable and hose. If the cable is still wound around the pump housing, it thickens it. In this case, you need to feed it down and also move the cable like a fishing rod. The cable will gradually unwind and allow the pump to continue moving.

Bottom silting

When silt and dirt form at the bottom of the well, the apparatus is pulled out by gradually swinging from side to side by the rope and hose. However, if the depth is large enough, the length of the cable will not allow to swing the device to the required extent. To get the stuck unit, you need to dilute the sludge large quantity water. Preferably under good pressure. Would need additional source water and equipment for supplying it to the mine shaft. It is advisable to lower the tube to the very bottom and use a pump to pump water under pressure into the well. Simultaneously with the supply of fluid, the cable must be pulled up, creating tension in the soil lock. After a few minutes, the equipment should be free. But do not rush to immediately pull it up. To rinse the sludge a little, the pump must be dipped several times in water without stopping its supply.

Reverse siltation

In this case, the apparatus is completely blocked in the ground, and often a soil cap is formed over it; more water. Just swinging and pulling out the device will not work. Otherwise, the cable will break and it will be more difficult to get it. To dilute the sludge, you need to lower a tube with a diameter of 15-25 mm into it, and then, using another pump, pump water down from the surface, and the more water, the better. Now the stuck unit can be safely pulled out.

Important: a fire engine is sometimes used to pressurize the well. This is expensive, so before pulling out the pump in this way, it is necessary to calculate the profitability of the procedure to the cost of the device.

Got trash

A foreign object in the barrel is one of the few reasons not to take any action to remove the stuck device. If, after passing a few meters, the pump stood up with a characteristic snort or knock, you can try to pull it out along with the object. Of course, the garbage itself is not visible, which means that one can only guess what is there. Translational movements up and down can loosen it and move it. It didn’t work out - you have to throw the pump inside.

Casing deformation

In this case, there is a narrowing of the diameter of the mine shaft. When moving up, the device rests against a bulge in the pipe. Any work to remove the pump has to be done blindly, but there is an excellent method that will work when the column is deformed.

It is necessary to make a special pencil case with your own hands, a mini-video camera is placed in it, pointing down. The camera must be in a waterproof case. A flashlight, also waterproof, is tied to it. The diameter of the case with the camera should be 1.5 times smaller. The pencil case is tied to a rope and lowered into the well. The camera clearly shows the place of narrowing and the possibility of moving the device further.

Skew and hook for joints in the pipe

This happens quite often. If the pump has become a wedge, it needs to be swung. With one hand we pull on the cable, and with the other on the hose or cable in turn. And they can not be pulled too hard or sharply, they can come off. Movements such as swings will loosen the equipment and bring it into the correct vertical position.

The same applies to the case with the hook of the pump at the joints. Almost similar movements contribute to the buildup of the pump and its release. You can lower the device half a meter lower and try to raise it again by moving the rope or cable along the walls of the entire circumference of the pipe.

Jamming on the rise

If the device has stood across the pipe, and when the cable is loosened, it sags and does not feel tension, you will have to resort to another method.

You will need a long pole or tube with a diameter of 15 - 20 mm. Can be used propylene pipe. It bends and will easily enter the shaft of the mine. Having placed the bar inside, you need to try to push the pump down, while loosening the cable and cable so as not to break them. A small spatula is attached to the end of the rod. Having lowered the device, the device is lifted up, pushing from below.

In sand and limestone wells

In the first case, siltation of the pump and the bottom of the pipe occurs. Especially if water is rarely used, and the well has stood idle for several months. It is clear that it is difficult to remove the unit from wet sand. But there is a way. In order for water to penetrate between the wall of the pump and the ground, it must be gradually, not jerkily, pulled up, and then briefly loosen the cable. Then do it all over again, it can take a long time. It all depends on how thick a layer of sand has formed around the device. So, by several centimeters, the device is gradually removed from the sand captivity.

Important: do not try to wash the sand with water pressure, this will only lead to its compaction.

In the second case, the situation is similar with sand. lime deposits when interacting with oxygen and metal, forming stone walls. To release the apparatus from back siltation, do not attempt to pump water or mechanically break the stone. This may damage the equipment. When swinging, it must be turned on. Vibration from the unit will help it free itself faster.

How to get the unit if the cable breaks

This is a disaster in which the owners throw the equipment right in the trunk and lower the new one there. Of course, this can be done if the unit fell to the bottom and drowned. And the depth of the mine allows water intake to be higher than before.

When the break occurred above the water level, the unit will still have to be removed. Need to do it yourself special device. By analogy with a mixer or a kitchen whisk, we twist a spiral with a sharp end slightly larger than the pump itself from the armature. We lower it into the well and weld the rod, immerse it again and attach another rod. So to the very bottom. Armature is needed to twist the spiral and capture the device. If the device could not be hooked, after rotational movements, the remainder of the cable will twist onto the trap and the pump will rise.

Important: to avoid problems with cable breakage, it is chosen from the very beginning with a sufficient margin of safety. A safety bolt is installed in the hitch with the unit.

What Not to Do

Pull firmly on the hose or cable. They can come off.
Continue to operate the pumping equipment. This will aggravate the situation.
Start actions to lift the pump without finding out the cause of its jamming.
Work with the included power cable leading to the pump socket.

When installing pumping equipment, the cable must be chosen very durable. It is better if it is stainless steel covered with a silicone braid. At the ends of the cable, locking rings with bolts are tied.
The well must be flushed and cleaned every two to three years of use.
If water is not used, the equipment must be pulled out of the mine shaft.
The pumping device is selected according to technical specifications that are suitable for different type wells separately.
The diameter of the flask is chosen less by 40-50 mm.
To prevent the supply cable from sagging in the column, it is tied with special clamps to the cable and pipe.
Do not pull on the hose.

Advice: when the pump is stuck in the well and it cannot be pushed through, the principle of pressure on the lever will come to the rescue. The mash is shallow and you can see where the flask is. We take a pipe or fittings with a diameter of 32-40 mm and immerse it in the mine. On the edge of the casing, we weld or fasten a strong eye, into which we thread another tube 2-3 meters long. Now just press the lever on the axial pin. Gradual pressure on the flask will ensure a smooth downward push.

Details of the submersible vibrator:

The use of a submersible pump has one significant drawback - operation at great depths. For this reason, the owners water intake workings often face the problem of equipment jamming in the wellbore and the inability to retrieve it to the surface. How to get the pump out of the well without damaging it? It depends on the reasons why the unit is stuck, on its type and the condition of the casing.

In most cases, well owners have problems with lifting pumping equipment that has already worked for a certain time in development. Lifting the deep pump is necessary in the following cases:

carrying out repair work;
Maintenance;
replacement with a more powerful or new pump;
replacing the flush pump with a permanent one.

Much less often, the pump jams in the wellbore when trying to lower it to the bottom of the well. The causes of sticking in this case are, as a rule, a mismatch between the size of the pump and the diameter of the casing pipe, or the ingress of a foreign object into the string, which prevents the descent of the unit. These two reasons are easily eliminated: the size of the pump is selected before the start of the descent, and the foreign object that has fallen into the casing is removed or pushed down.

To prevent the pump from getting stuck during descent, it is necessary to observe safety measures: carefully inspect the unit and make sure that all its parts are in good order, avoid foreign objects (stones, tools, packaging) from entering the pipe, use a reliable cable and clamps.

Pump stuck problems usually occur when the pump is pulled from the well to the surface. The most common conditions for which equipment can get stuck in the barrel:

sagging rope (cable);
siltation of the well "on the sand";
deposits in the well "on limestone";
casing wall damage;
ingress of foreign objects into the pipe;
the pump is skewed inside the casing;
cable break.

If you have a pump stuck in a water well, then the most the right decision- call for specialists who have experience and necessary equipment to safely remove the unit, but in some cases you can try to get the pump yourself, identifying and eliminating the cause of its jamming. Consider the described causes and ways to eliminate them in more detail.

If there is a slack in the cable or electric cable used to lift the pump, the unit gradually pulls up worse and worse, and at a certain point it stops altogether. This is because a slack cable or electrical cable has wrapped itself around the pump housing.

Algorithm of action in case of cable or cable sagging:

Lower the pump to the bottom and carefully align the loop formed by slowly swinging the cable in different sides and pulling it up.
If only a cable is used for lifting, then do not forget that the pump is also equipped with an electric cable and hose, which must be synchronized with each other in order to avoid sagging of one of the elements and the formation of loops.
Fix all three elements with clamps. Fastening must be carried out every 1-1.5 meters.
Raise the pump slowly and carefully.

This is the most common and easily solved problem. It is very simple to prevent sagging of the cable; for this, when lowering the pump into the well, it is necessary to tie it in casing pipe every 2-3 m, so that it always remains under a little tension.

Silting wells with a sandy bottom occurs due to infrequent or improper operation. In this case, the pump is trapped in a muddy "trap" and you can get it by alternately pulling and loosening the cable, while slowly swinging the unit in different directions. Thus, it is possible to free the equipment from silt deposits.

In unused workings, silt can harden, therefore, before removing the aggregate, the deposits must first be washed out. For this, a fire hose or a flexible hose is taken, through which water is supplied to the bottom of the well.

The soaking of silt deposits can take from 2 to 48 hours. To check whether the pump is free from silt, it is necessary to periodically try to lift it, swinging it from side to side. If the device does not give in, then do not make excessive efforts, let the soaking of the sludge continue.

The problem of pump overgrowth with silt occurs if the well has not been cleaned for several years. Annual preventive cleaning of the hydraulic structure and downhole filter completely eliminates the problem of silting, and hence equipment jamming.

The water extracted from a limestone well contains many salts and metals, which, interacting with oxygen, form a solid precipitate. Such sediment can be seen on the walls of casing pipes. Exactly the same deposits accumulate on the body of the pumping equipment, forming salt growths, the layer of which can reach 5 cm. It is clear that when the pump is lifted, its dimensions increased due to deposits will not allow it to pass through the casing pipe.

In this case, there are three ways to solve the problem:

Flushing the well with water. She is sent to the trunk under high pressure. This method is good when there are few deposits, and they are amenable to erosion. In this case, after carrying out a high-pressure washout, the pump is lifted up by means of a cable or cable.
The use of "folk" remedies against scale. Instead of special powders, citric or acetic acid is taken, diluted in water and poured into the borehole. Salt deposits break down under the action of acid. This method can only be used on a pump that is not going to be used again because acids can damage its internal mechanisms.
Uses chemicals . For this, anti-scale agents for washing and dishwashers, teapots. The powder must be dissolved in hot water in accordance with the manufacturer's instructions and pour the resulting solution into the well. To increase the effectiveness of anti-scale agents, it is recommended to turn on the pump (if it is working) so that the water starts to move.

The disadvantage of the latter method is its high cost: you will need at least 20 packs of anti-scale agent, and in some cases you need to repeat the procedure 2-3 times.

When lifting the pump, it may get stuck due to mechanical damage casing pipe. Such damage includes:

a dent in the casing;
flattened edge of the pipe;
roughness of welds;
displacement of welded parts, etc.

A characteristic symptom, indicating that the pipe damage has become an obstacle to the movement of the pump up, is a thud and jamming of the unit, which until that moment had moved along the alignment without problems.

In this situation it can help little change position of the pump, it must be tilted and slowly rotated while lifting up. Please note that it is necessary to tilt just “a little”, otherwise you risk breaking the cable by dropping the device into the well. You should not make excessive efforts trying to push the pump through a difficult area, this will lead to a complete jamming of the unit inside the well.

Practice shows that with minor deformations of the casing and small dimensions of the pump, this method helps in most cases. If the dimensions of the device are slightly smaller than the cross section of the casing or the damage to the string is significant, then it will not be possible to get the pump on your own, and in some cases even specialists cannot do it.

To prevent equipment jamming due to casing pipe deformation, it is necessary to carry out high-quality installation of casing strings in compliance with all technological standards and correctly select the unit according to its dimensions.

most annoying and dangerous situation which, however, is very easy to prevent. Most often, tools, fasteners, debris, trimmings get into the casing plastic bottles. To avoid this, it is necessary to carefully prepare for lifting the pump, removing everything unnecessary in the work area.

If a foreign object has nevertheless fallen into the pipe and interferes with the lifting of the equipment, then the following steps can be taken:

Gently and slowly, without effort, shake the pump from side to side, if possible - a small object can slip into the well, clearing the way for the unit.
If the pump cannot move upwards, and the device goes down without problems, then you need to lower the pump a little and try to get dropped object using a net, hook or rope with a loop.
In some cases, you can try to push the fallen object with a hard cable or crowbar. This must be done very carefully, because. there is a high risk of breakage of the lifting cable and damage to the pump housing. Excessive efforts in this case should not be applied.

If these measures were not enough, and the pump is completely stuck in the well due to the ingress of a foreign object between its body and the walls of the casing, then it is necessary to stop trying to solve the problem on your own and call a team of specialists who will remove the obstacle and raise the pump to the surface without damaging it .

Causes of pump misalignment can be sagging cable, a sharp jerk of the lifting cable, lifting the unit with an electric cable, etc. The following signs indicate the presence of a skew: the pump rose without problems, but at a certain point the rise slows down and stops, while there is no blow. In no case should you continue to pull the device from the well, because. this will lead to even more skew and jamming!

Only decision problems - loosen the cable tension and, lowering the pump, try to return it to its original position. To do this, the lifting cable must be rotated, gradually pulling the pump up, if the unit is stuck again, then you can try to rotate the cable in the other direction. When lifting is done with the help of a cable and an electric cable, then by manipulating them one by one it is quite easy to return the device to the required position.

It is advisable to do all this if the pump moves freely in the well up to a certain point and goes down without any problems. If the unit is stuck in the well and does not have free play, then it is necessary to call specialists who will remove the device using special tools without damaging the pump and well.

A break in the lifting wire is the most difficult case in which the pump falls to the bottom of the well or gets stuck in the casing. First aid in case of a cable break is to stabilize the unit. For this, a hose and an electric cable are used. If the pump has small dimensions and weight, then with the help of a cable and a hose it can be carefully pulled to the surface, despite the fact that these elements are not designed for this.

If the pump is heavy, then you can’t pull the electric cable, this will surely lead to its breakage. In this case, you need to act quickly: take a thick rope with a metal hook tied to it. Then gently lower the rope, trying to hook the pump with a hook and pull it up. The hose and power cable are used to secure and level the device during lifting.

When the cable broke suddenly and the pump fell into the well along with the hose and electric cable, you can try to get it yourself using the following method:

We take a metal rod of such length that it reaches the fallen / stuck unit.
We attach a special nozzle in the form of a corkscrew to the rod. A blacksmith, a milling turner can make such a twisted nozzle, or any ready-made nozzle can be used as a nozzle. suitable item. At the same time, it is important that the diameter of the turns of the nozzle be such that the rod passes unhindered through the casing.
The nozzle is attached to a rod, on the second end of which a metal rod is put on, which makes it possible to ensure the rotation of the structure.
We lower the rod with a nozzle into the well and use the rod to screw the “corkscrew” into the pump housing. Raise the unit together with the broken cable and hose.

This is a rather complicated and difficult to implement method, suitable only for shallow wells. Naturally, further use of equipment lifted by such a "corkscrew" will be impossible. Extract dropped pump so as not to harm him, you can’t do it yourself, and the services of professionals in this case can cost you dearly.

If lift submersible pump on the surface is impossible in any way, then there are two ways out:

conservation of the well and drilling of a new one;
crushing the pump into parts with a special drilling rig and extracting it in parts.

Which way to choose? In each case, the owner of the well decides for himself, taking into account many factors.

It happens that a well has exhausted its resource or its operation is difficult for some reason, then it is easier and faster to drill a new one.

A stuck submersible pump is easier to prevent than to fix the problem later. To do this, you need to follow a few simple recommendations:

Use a reliable, durable and rigid cable. The cable that comes with a submersible pump often does not meet these requirements. Do not be stingy, get a high-quality cable and fasteners (clamps) to it made of "stainless steel".
Do not use multiple pieces of hose. If the hose supplied with the pump is not long enough, you should not extend it, it is better to buy a new one whole piece. This will reduce the risk of breakage and serve as additional insurance in the event of a cable break.
Choose the right pump size. It should be 2/3 less than the diameter of the casing. Thus, the risk of jamming of the unit will be significantly reduced even if the pipe is deformed or foreign objects fall into the well.
Be sure to install a cap. It will protect the well from falling debris and various objects.

And remember: using the methods described above, in no case use brute force, trying to pull the unit to the surface. This will lead to an aggravation of the problem: the pump will get stuck even more tightly inside the barrel, the cable may break, and the wall and casing will deform.

How to get the pump if it is stuck in the well and how to prevent it from getting stuck:

Removing a stuck pump with a lifting cable:

Submersible pump stuck in a well serious problem which requires an immediate solution. In this case, as nowhere else, the “do no harm” rule applies, so when attempts to remove equipment were unsuccessful, best solution experts will be called. Be sure to follow the rules for the installation and operation of the well, clean it in a timely manner and then you will never encounter such problems.

Have you encountered the problem of submersible equipment jamming in the wellbore and the inability to retrieve it to the surface? Agree, it’s not bad at all to pull it out on your own, restoring uninterrupted water supply, and at the same time save on the departure of a specialist. But you don't know how to get the pump out of the well without damaging it?

We will tell you how you can deal with this task yourself - the article discusses the most common causes of pump jams and methods for removing it. Video recommendations of professionals are given and the equipment used in this case is considered.

The article also selected photographs demonstrating methods for pulling out a submersible pump operated at great depths. The above recommendations will help to cope with the problem if the reason why the unit is stuck, its type and the condition of the casing pipe will allow it.

In most cases, well owners have problems with extraction, which has already worked in development for a certain time.

Lifting the deep pump is necessary in the following cases:

carrying out repair work;
Maintenance;
replacement with a more powerful or new pump;
replacing the flush pump with a permanent one.

These two reasons are easily eliminated: it is picked up even before the start of the descent, and a foreign object that has fallen into the casing is removed or pushed down.

Usage surface pump instead of deep, it will avoid problems that arise when lowering and raising equipment inside an aquifer

Jam Causes and Solutions

Pump stuck problems usually occur when the pump is pulled from the well to the surface.

The most common conditions for which equipment can get stuck in the barrel:

sagging rope (cable);
siltation of the well “on sand”;
deposits in the well “on limestone”;
casing wall damage;
ingress of foreign objects into the pipe;
the pump is skewed inside the casing;
cable break.

Such damage includes:

a dent in the casing;
flattened edge of the pipe;
roughness of welds;
displacement of welded parts, etc.

In this situation, a slight change in the position of the pump can help, it must be tilted and slowly rotated while lifting up. Please note that it is necessary to tilt it “just a little”, otherwise you risk breaking the cable by dropping the device into the well.

You should not make excessive efforts trying to push the pump through a difficult area, this will lead to a complete jamming of the unit inside the well. Practice shows that with minor deformations of the casing and small dimensions of the pump, this method helps in most cases.

If the dimensions of the device are slightly smaller than the cross section of the casing or the damage to the string is significant, then it will not be possible to get the pump on your own, and in some cases even specialists cannot do it.

If the damaged casing is located close to the surface, it is advisable to partially extract the casing to the link with the stuck pump and replace or repair

Reason #5 - Ingress of Foreign Objects

The most unpleasant and dangerous situation, which, however, is very easy to prevent. Most often, tools, fasteners, debris, trimmings of plastic bottles get into the casing. To avoid this, it is necessary to carefully prepare for lifting the pump, removing everything unnecessary in the work area.

If a foreign object has nevertheless fallen into the pipe and interferes with the lifting of the equipment, then the following steps can be taken:

Gently and slowly, without making any effort, shake the pump from side to side, if possible - a small object can slip into the well, clearing the way for the unit.
If the pump cannot move upwards, and the device goes down without problems, then you need to lower the pump a little and try to get the fallen object using a net, hook or rope with a loop.
In some cases, you can try to push the fallen object with a hard cable or crowbar. This must be done very carefully, because. there is a high risk of breakage of the lifting cable and damage to the pump housing. Excessive efforts in this case should not be applied.

If these measures were not enough, and the pump is completely stuck in the well due to a foreign object getting between its body and the walls of the casing, then it is necessary to stop trying to solve the problem on your own.

A team of specialists should be called in to remove the obstacle and lift the pump to the surface without damaging it.

Reason #6 - skewed pump inside the pipe

In no case should you continue to pull the device from the well, because. this will lead to even more skew and jamming! The only solution to the problem is to loosen the cable tension and, lowering the pump, try to return it to its original position.

To do this, the lifting cable must be rotated, gradually pulling the pump up, if the unit is stuck again, then you can try to rotate the cable in the other direction. When lifting is done with the help of a cable and an electric cable, then by manipulating them one by one it is quite easy to return the device to the required position.

A submersible pump operating in a water well sometimes has to be taken to the surface for repair, preventive maintenance, replacement with new or more powerful equipment. If the source is equipped correctly, and you periodically check the condition of the device and its mounting, there are no problems with this. But if it so happened that the pump got stuck in the well, how to pull it out without damaging anything and without breaking the cable?

Causes of the problem and solutions

There is one common reason why the pump becomes difficult or even impossible to get out of the well. It's non-compliance technological requirements to the device of the well itself and the fastening of equipment in it, as well as improper operation of the water source. If the instructions were strictly observed during these works, the dismantling of the device will be easy and simple.

What leads to such consequences?

Sand well silting

But it is even more important to properly equip it, starting with the manufacture of the casing, which should be perfectly straight, with smooth inner walls.

Install a nozzle in the well of such a diameter that the gap between its body and the walls of the pipe is sufficient. It will cost more than larger analogues, but its price cannot be compared with the cost of equipping a new well.
For installation of submersible equipment, use only a strong, high-quality stainless steel cable, securely attaching it to the device.
Neither the suspension nor the pressure hose must be spliced from separate sections. They can disperse when lifting the pump, the pieces will fall down and jam it, preventing free movement.
To electrical cable does not sag, attach it with clamps to the hose before starting the descent of the device into the well.

Note. Do not tie the cable to the suspension cable - the clamps from it can fly off under strong tension.

To prevent foreign objects and debris from getting inside the well, install a special head on it (see), tightly closing the mouth.

Conclusion

The video in this article will show you how to proceed if you cannot get the pump out of the well. If this problem has not touched you yet, re-read the tips above and think about what you can do to prevent this from happening in the future.

If your pump is stuck in a well or has fallen into a well, check out our instructions. Lifting pumps should be done carefully, as there is a high probability of making a mistake and damaging expensive equipment.

5 Causes of Pumps Stuck in Wells

Before you pull the pump out of the well, you need to determine the exact cause of its jamming. This will make it possible to choose the most effective way to eliminate the breakdown, which will reduce the risk of failure of pumping equipment.

There are 5 main causes of the problem:

Sagging power cable. This is the most common situation faced by every third owner. autonomous system water supply. The main signs of the problem are not only the sagging of the cable when lifting the pump from the shaft, but also its winding around the equipment body. In this case, even the application of great efforts will not allow you to move the device.
Stuck in limestone. Rare maintenance of the mine causes stagnant water. Because of this, metal salts form limescale. It securely fixes the pump and makes it impossible to pull it up.
Well silting. Using the pump for several years and not wanting to carry out cleaning activities leads to the fact that a large amount of sludge accumulates at the bottom. It completely covers the body and does not allow you to lift the device up.
Mechanical damage. Most often, the pump is stuck in the casing, which was damaged as a result of a heavy object falling into the mine or inaccurate human actions during cleanup.
Hit by a foreign object. If it gets stuck in the pipe, then do not allow the pump to be pulled out of it.

5 ways to get the pump out of the well

Experts recommend using several proven methods that allow you to quickly fix the problem. To pull out a stuck pump, do not use excessive force, which can only damage the device and disable it.

How to get a stuck pump

To quickly get rid of the problem, you need to know how to get the pump out of the well if it is stuck and does not move. For every reason there is a solution.

This is how the vibration pump can get stuck in the casing

Available methods:

Cable slack. If this situation occurs, you need to slowly and carefully lower the device. As soon as it is at the bottom, loosen the cable and try to lift again. At the same time, they move slowly, trying to avoid sagging of the electric wire and other structural elements (cable, hose).
Silting. With such a problem, it will be difficult to lift a stuck device. To remedy the situation, silt deposits must first be washed out. To do this, carefully swing the cable, in parallel trying to lift the stuck device. Gradually, the "grip" of the silt will weaken and after a few minutes of such work it will be possible to raise the equipment to the surface.
Burrow in limestone. If such a problem occurs, you should perform all the same actions as with silting. Slow rocking will gradually break up deposits near the hull and allow you to lift the device from the bottom.
Pipe damage. To get stuck equipment will help rotational movements that need to be given to its body. Lift the device slowly, as one careless movement will be enough to damage its outer part.
Foreign object stuck in the shaft. In such a situation, you need to take the help of professionals, since it will be difficult to get this item with your own hands. This is due to the risk of it falling to the bottom of the well or damaging the hull.

What needs to be done so that the pump does not get stuck

It is difficult to get a stuck pump, so experts recommend taking all necessary measures to reduce the likelihood of a problem. To do this, you need to perform several activities.

These include the following:

Attaching the electrical cable to the hose. This simple action will help to avoid sagging of the wire and its wrapping around the body of the pumping equipment. Fixation is carried out using special clamps, which must be regularly replaced with new ones.
Placement of the pump above the filter. This installation option will avoid sticking to the body of silt, which often causes the device to get stuck.
Annual cleaning. Regular carrying out of this event will not allow silt and sand to accumulate at the bottom of the well.
preventive treatment. In this case, professionals recommend using citric acid for limescale removal. She will quickly deal with the problem and eliminate the possibility of the device getting stuck.
During the arrangement of an autonomous water supply system, only pipes should be used High Quality. Due to this, there will be less risk of breakage as a result of mechanical stress.

How to get a pump that has fallen into a well

If the cable breaks and the pump falls into the well, it will be difficult to get it from the bottom. Even if you manage to do this work, you will have to change the device to a new one.

Procedure:

Find a rod made of any durable metal. Its size should be enough to reach the bottom.
A special screw nozzle is attached to one edge, which is shaped like a corkscrew with a pointed end.
At the second end of the rod, a rod is fixed, which allows you to rotate a home-made structure.
lowered ready product and find fallen equipment.
Applying force, screw the screw nozzle into the body of the device.
As soon as it deepens to half its length, the pump slowly begins to rise.

What needs to be done so that the pump does not fall

Lifting a pump from a well is considered a difficult undertaking, so you need to try to prevent it from falling to the bottom. To do this, you need to take several steps. Among them are:

use the most rigid and durable cable;
use a one-piece long hose, and not assembled from several small pieces;
the pipe diameter should be selected in a ratio of 3:2 with the dimensions of the pump;
install a head on the well to prevent falling objects.

How to get the pump out of the well

Extraction of pumping equipment stuck or fallen to the bottom of the well is carried out in exactly the same way as for the well. Use a homemade anchor.

If the depth of the mine is more than 10 m, then it is recommended to contact companies involved in cleaning wells. Their workers have at their disposal special equipment, thanks to which they can quickly fix the problem.

If the pumping equipment is stuck in the well or is at the bottom of the well, you need to know what to do in such a situation. It is important to quickly take all necessary measures to reduce the negative consequences and eliminate the problem.
