Submersible pumps, which are used to supply water from wells in the area, periodically need preventive maintenance. It also happens that the equipment needs to be obtained for minor urgent repairs. The rise of the device is also due to the replacement of the unit with a model that is more powerful. This need arises with the time when the old device has served its time.
The operation of removing the submersible pump is not always successful, and the well pipe sometimes turns out to be a place where the pump simply gets stuck. Sometimes the equipment gets up tight, and the owners of the site, faced with such a problem, do not know what to do so as not to break the cable.
The main causes of jamming
If the equipment is stuck, how to pull the deep pump out of the well? First you need to deal with the main reasons why such a nuisance can occur. Usually they are caused by the human factor.
During the installation of the pump, the technological requirements for fixing the elements of the device may be violated. Sometimes it also happens that demands are made on the quality of their manufacture that have not been met. A favorable outcome is not expected, which manifests itself during the dismantling of the pump.
What to do if cable slack
If you are also faced with the question of what to do if the pump is stuck in the well, first you need to figure out the reasons. Sagging electric cable occurs most often. The cable is in a loop, which is wrapped around the equipment case. At the same time, pulling the device with all its strength is not worth it, since it certainly will not lead to success, but the cable can simply break. In this case, it is quite difficult to do something on your own.
You may try to push the appliance back. You can do this on your own. You can try again if you feel slack. In this case, you need to start a leisurely climb. It is better to prevent the situation being described than to try to fix it. In order not to run into sagging electric cable, you should fasten it with clamps to the hose or pipe. And this must be done even at the stage of installation of the system. It is not recommended to fix the cable to the cable, since the clamps can fly off during operation. When lifting equipment, you must ensure that the cable and hose exit to the surface at the same time. It is important to rule out slack in one or the other.
Well siltation
If the Malysh pump is stuck in the well, it is possible that silting has become the reason for this. This happens quite often when the water source is not used for a long time. As a result, a layer of sludge is formed, which becomes an obstacle to the equipment.
If you encounter a similar problem, you should swing the unit. During this, the device can be lowered or raised. This will lead to the fact that the water will begin to erode sediment, and the road up will be freed, which will allow you to remove the device out. You should not rush while exhibiting excessive activity. Indeed, otherwise a dull jamming of the unit may occur.
If the pump is stuck in the well, how to pull it out, you can only understand after you determine the cause. If it is accumulated sludge, then you can use a non-standard way of dealing with it. To solve the problem, firefighters should be attracted, who with their sleeve will be able to erode deposits. The sleeve is lowered into the well. When the pump is free, you can understand this, because it will smoothly go up. In order to exclude siltation of the well, it is necessary to subject it to preventive cleaning with a certain frequency, which is once every three years.
Overcoming a Complex Solid State Obstacle
If the pump is stuck in the well, how to get it, you can understand if you determine the cause yourself. It sometimes becomes a solid obstacle, which can be considered a rather complex barrier. If there is such an obstacle in the way of the device’s movement, then you can find out about it by the characteristic knock. The congestion will serve as a wedge, and sometimes acts as a wedge:
- flattened edge of the pipe;
- defects in the assembly of the column;
- burrs from the weld;
- a dent in the pipe.
The latter may occur due to movement of the soil. As for the burrs, this is the problem of the team that worked on the well. The reason may also be the marriage of the sedimentary column, which is expressed in axial displacement, when the threaded connection or welding is carried out poorly. With such an obstacle, the pump will freely pass down, but will not be able to move up.
If you have a well for water, and the pump is stuck in it, then you can solve the problem by rotating the equipment using a pipe around its axis. At the same time, the obstacle that has stood in the way can be circled. But the probability of freeing the device with movement is not one hundred percent. Success can be one-time. However, it’s still worth a try, because in each specific situation the problem can be resolved in this way.
Sometimes a situation occurs in which a solid-state obstacle falls into the well. It is a tool, a foreign object or a fastener component. In this case, the pump stops during a sharp rise. You can find out about this unexpectedly. When the device falls into the gap between the pump and the wall of the well, a solid object will not allow you to remove the equipment, which is the reason for jamming.
The downward movement will remain free, while the gaps upward will vary depending on the selection of the cable. Experts advise calling professionals to solve a similar problem, because only with the help of appropriate equipment it will be possible to remove interference.
Reverse siltation
If the pump is stuck in the well, you can find out ways to get it if you read the article. Among other problems, one can single out the effect of reverse siltation, which is observed where the well is located in limestone soils. During long-term operation, the sedimentary layer will grow over the place where the equipment is located. The result is a cork. In order to stop this process, the well must be cleaned every three years.
Additional extraction recommendations
A stuck pump with a dangling cable can be removed using metal fixtures with pins. In the people they are called a cat. The pump can be hooked, which is considered a great success. You can grab the end of the hose or cable, then the equipment can be pulled up.
In order to push the pump down, some inventors use scrap tied to a rope. You should strengthen it firmly enough so that it does not stay inside when you throw it. So you can act in the case of an old device that is not intended to be used further. The probability of damage to the unit is very high, but this technique can work with a small depth of the device.
If the pump is stuck in the well, you can use a pipe to which the ear is welded. A cable, a cable or a hose is passed through a pipe, and after the device is lowered into a separate cable inside. Under pressure from the equipment, the equipment can slip down and hang on the cable. Pull the pipe and pump to the surface at the same time. The weight of the structure can reach 50 kg, so for work it is necessary to enlist the help of another person.
Additional tips
If the pump is stuck in the well, and its suspension was not cut off, then with force extraction it is possible to fix the equipment in a tightened state and tap it periodically. When there is a weakening of the cable, you can re-pull it and knock again. These actions are repeated for several days. The method is suitable only for especially patient masters, but will succeed only in individual cases.
How to prevent a problem
To prevent the pump from getting stuck in the well, you can try to prevent this from happening. To do this, you should not save on the quality of the cable. To suspend submersible equipment, stainless steel fasteners and cable should be purchased. Inside the well, it is not recommended to use pieces of cables and hoses that are spliced together. When lifting, weaknesses can disperse, and the scraps will bend and cause the device to jam.
It is recommended to purchase a pump so that it has a minimum diameter for a particular well, which will increase the gap between the walls and the body. Pumps of small thickness are more expensive than more bulky counterparts, however, when comparing the difference in cost with the price of a new well, acquiring a thin device becomes profitable.
What else is important to remember
Replacing the pump will reduce the likelihood of it sticking in the future. It is recommended to install a head on the well, which was performed in the factory. It must be mounted in such a way that it is located as tightly as possible to the pipe walls. This part will prevent debris and random objects from getting inside.
Conclusion
If the pump gets stuck in the well, then many craftsmen begin to come up with sophisticated ways to solve this problem. The high cost of the services of those firms that are engaged in this direction pushes them to this. Sometimes the cost of a specialist in such a company reaches the cost of installing a new well. To save the budget, you must try to do everything possible to prevent jamming of the equipment or try to solve the problem yourself, which, however, is not always possible.
