How to fix the pump in the well with a cable

Autonomous water supply site is not limited to the device of the well. It is necessary to deliver water to the points of water collection through the pipeline. When the depth of the source exceeds 7 m, a submersible pump of the vibratory or centrifugal type should be used.

Their design allows water to be raised from depths up to 90 m with the required pressure, while the energy consumption is much lower than that of the surface aggregates. The advantage of submersible pumps is relative silence during operation, as water serves as a natural sound insulator. only heard as the relay clicks.

In addition, such equipment is protected from frost and can show stable and efficient operation at any time of the year. The main issue in the operation of a submersible pump for the well is the correct choice of model to fit your needs, as well as the correct installation of the pump in the well.

Characteristics of a submersible pump

It is possible to make a logical conclusion from the name of the equipment that it should work submerged in water. This allows the latter to cool its body and engine. When the water level at the source drops to a critical level, the protective system “dry running” turns off the pump.

Equipment that has been developed exclusively for this type of source can be used in wells as well as well. Their device is almost the same, they are distinguished only by the shape, price, it is slightly lower, and size.

At the same time, the narrow shape and small diameter of the downhole equipment is rather a disadvantage for use in wells. For example, when the length of the pump for wells is 900 mm, it will be difficult to withstand conditions in a shallow source, which prescribe that the pump does not lie below 1 m in the well to the bottom. But this does not prevent them from being used even more often than standard equipment.

Types of pumps for wells are divided into:

• centrifugal;
• vibrating;
• augers;
• whirling.

The principle of their work is different.

Choosing a submersible pump

Beforehand it is necessary to know how to calculate power of the pump for a well. For example, the performance of the equipment must meet the needs for water, while it can be even slightly higher in this parameter.

The required consumption is determined by summing up the consumption of the washbasin, kitchen sink, washing machine and shower. In addition, you can add here and use of water for irrigation, sinks in the kitchen, bathroom and washing machine.

In the second stage, determine the actual consumption per unit of time. Agree, it is improbable that all points of water analysis turned on at full capacity at the same time. For this, the total flow rate can be taken as 60-80%, and if the pump capacity is expressed in m3 / h, the values ​​in l / h should be multiplied by 3.6.

Pump installation

If you, before connecting the pump in the well, did not develop a scheme for supplying water to it, then it is time to do it. Equipment installation is the last thing to do.

It is safe to say that connecting the pump to the well and laying the pipeline is not difficult. It is only necessary to follow the well-known rules and some nuances. It is better, of course, when you take someone to help you, so that there is some insurance in the actions.

Device plumbing

It is necessary to stretch the pipeline, even if you will not use the pump to supply water to the house. It is impossible that next to him formed a puddle, the water from which can get back into the mine source. In extreme cases, take the water 2-3 m to the side and make a tap, and place a place next to it and make the drain away from the source.

To supply water to the house, it is necessary to make a trench with your own hands or with the help of equipment at a depth that will not allow water to freeze in the pipe in winter. If the conditions of the site do not allow, then it is necessary to make it warming with the use of foam plastic and mineral wool. You can also wrap it with a heating cable, which will not allow the liquid to freeze and destroy the pipeline.

To prevent damage to the plastic water supply pipe, make sure that there is no broken glass, sharp stones or other cutting objects in the trench. Cover the bottom of the pit with a layer of sand and lay out with geotextiles.

Installation

An instruction is provided to help you understand the process:

1. Prepare a cable for hanging, it is better that it was made of stainless steel, but galvanized and nylon will do.

1. Make a mounting frame for suspension. To do this, take the corner with a shelf 50 and weld a square frame from it, and then install it on the top of the well.

1. Drill a hole in one of the corners for pulling the cable and fixing it.
2. Prepare a tee for withdrawal from the pump to the pipeline.
3. Connect it to the equipment.
4. Unwind the electrical cable to the required length.
5. Install a check valve on the outlet of the pump, if it was not provided for in production. At the same time use sanitary plumbing material.
6. Attach a brass or plastic coupling to the non-return valve.
7. Connect the pipe to the coupling.

1. Attach the electrical cable to the water pipe with plastic clips or electrical tape with a step of 500 mm, then it will not hang out in the well.

Tip: coil the cable is not tight, but with a small slack.

1. Thread the safety cable into the lugs located on the top of the pump and fasten it.
2. Put all the details in a straight line so that you can:

• trumpet;
• on her electrical cable;
• near safety cable.

1. Start slowly lowering the pump, it is desirable that you have an assistant in this process.

Tip: lifting, lowering, and replacing the pump in the well is done only by the cable; it is forbidden to do it by the cable.

1. Lower the equipment to the desired depth of the well construction, we recall that it should not be closer than one meter to the bottom of the source, secure the second end of the cable to the frame frame. Pass the end through the hole and fix.
2. Attach a vertical pipe with a tee to the equipment. To do this, you need to go down into the well and connect them among themselves by an American with sanitary paste and tow.

Tip: In order not to sink into the well for installation work, you can use a flexible hose for the pump in the well or a soft pipe to carry out all the work from above.

1. The electric cable can be brought upstairs, or it can be brought into the trench, if it was decided in this way to bring it into the house.

When pumping equipment is installed, it is possible to continue laying the pipeline through the foundation and supplying it to the point of installation of the accumulator, filter and boiler. Upon completion of the installation work, wrap the trench in geotextiles and cover it with a sandy layer 100 mm high, and then with soil.

Optional equipment

No one argues that you can use the pump for the well in a simple way, press the button when you need water in the house. Another option is to automate the process, which will require a hydroaccumulator and a pressure switch.

The first serves as an intermediate link between consumers and the pump. Moreover, its use significantly increases the service life of the equipment. You can pick up such a volume of capacity that water with a certain pressure is enough for several hours, and the pump will be inactive.

The pressure switch is used to automatically turn on the pump at a critical level of water in the hydroaccumulator. After filling the tank it will turn it off.

Conclusion

The process of installing a submersible pump in a well does not cause difficulties, it is only necessary to adhere to certain rules. In addition, it is necessary before this to provide options for draining water from the source, preparing everything in advance.

A large role in increasing the service life of the equipment is played by additional accessories - a hydroaccumulator and a pressure switch. In the presented video in this article you will find additional information on this topic.
