Installation of the pump in the well. Installation, self-connection

Installation of the pump in the well can be done independently. This will allow residents of country houses and owners of dachas to use clean drinking water, which can be produced without interruption and with ease.

Mounting technology

Before starting the pump installation, it is necessary to analyze whether there are curvatures, narrowing or crookedness of the casing. Such problems can complicate installation, as well as significantly shorten the life of equipment. The installation of the vortex pump on the well should be done taking into account the difference between the pump and pipe diameters. If it is too small, the existing surface defects can adversely affect the operation. Whereas if the difference is too large, the pump can burn. In the latter case, the necessary speed of water movement, which is required to cool the engine, will not be provided. The minimum permissible values should be indicated in the technical documentation. Installation of the pump in the well involves the suspension of equipment on a nylon cord, which will be able to undergo a tensile load (it must exceed the weight 5 times). In order to exclude the absorption of the assembly on which the suspension is fixed, it should be tied, having deviated from the inlet holes to a minimum of 10 centimeters. As for the ends, they should be scorched. If the equipment is supposed to be lowered by less than 10 meters, at the end of the rope it is necessary to fix an additional spring suspension, it must extinguish vibration. To do this, you can use a flexible rubber band or a medical tourniquet.

Recommendations for work

Installation of the pump in the well is carried out according to a certain technology. It eliminates the use of a cable or iron wire in the role of suspension. This is due to the fact that these materials are able to break the fasteners, which are located on the aluminum case of the equipment.

What is important to know

Kapron suspension, power cord, as well as a plastic metal pipe must be fixed with an electrical tape, observing a step within 130 cm. The first bunch should be removed from the pump branch pipe by 30 centimeters.

Connectivity

When the centrifugal pump is installed in the borehole, the connection does not have to use threaded connections. They are able to reduce the strength of pipes that are corroded. Longer life span has flanged connections. When using them, the mounting bolt must be installed from the top, while the nut is strengthened from below. This is because the fallen bolt can cause serious accidents. On the base plate, you need to fix the discharge pipeline, or rather, its upper end. At the next stage, a non-return valve is mounted on it, if the pump is empty.

At this stage, the knee, valve and pressure gauge must be connected to the water supply system. Now the suspension is strengthened to the crossbar. This is the last thing that will have to be done until the pump is in the well. The installation of a surface pump per well involves the process of lowering the equipment, which should not touch the walls. If this possibility can not be ruled out, the body is recommended to be protected with a rubber ring. To measure the water level in the well, it is necessary to mount a gas pipe string, which is installed in the hole of the support plate. Immerse it below the dynamic level.

With a megger, it is possible to determine the insulation resistance of the motor winding with the cable lowered. Then connect the control station to the equipment, checking if the pump is sufficiently submerged in water. The installation of the pump in the well, the price of which will be indicated below, requires the evaluation of the correct functioning of the electric motor under the load.

Determining the depth of the pump

If you independently install a deep- well pump into the well, it is important to consider the depth at which it will be located. The static level is the length of the segment from the surface of the earth to the surface of the water, which is true in the natural state. Water must be pumped out of the well. The level at which water stops will be called dynamic. In order for the engine to cool properly, lower the equipment must be 30 cm lower relative to the dynamic level. As the most suitable depth, a dip of 3 meters below the mentioned mark is taken. It must be remembered that the distance to the bottom of the well should be two meters.

Installing the pump in an accident

Installation of a deep-well pump in the well is sometimes carried out after an accident. Such a need appears quite rarely, as a rule, this is due to the fact that the installation technique was not followed the previous time. The cause of the accident may also be in the improperly selected automatic power supply, the problem may also lie in the insignificant capacity of the equipment itself. Thus, if the pump is designed to dive to a depth of 50 meters, and it was buried at 80 meters, repair will be required after a few months of operation. The power supply automation is designed for working water pressure, whereas from an incorrect depth a sufficiently weak pump will not be able to lift the liquid upward. Ultimately, the installation will work continuously, which will cause a rapid failure.

Self-service pump replacement

Re-installation of the submersible pump into the well can be done both independently and with the help of specialists. If for you the first option is the most acceptable, then it is necessary first to make sure that the equipment is functioning properly. If you decide to independently perform such work, then you should enlist the help of five people. This is due to the fact that you have to work at 100-meter depth, and the cable, suspension and pump will have a weight equal to about 250 kilograms. Initially, it is necessary to prepare a metalwork tool, a shrink sleeve, an electric soldering iron, consumables, a construction hair dryer and scissors. At the next stage, it is necessary to disconnect the trunk that goes into the house from the well head. Among other things, disconnect the power cord of the equipment. A latching element can now be loosened.

Some nuances of work

Installation of a submersible pump in the well must necessarily be accompanied by the use of a safety line, which is used when lifting old equipment. This requirement is due to the fact that the pump cable may fail, and it will be impossible to raise it. In the end, this will lead to the fact that it will not be possible to use the well in the future. After the pump is lifted to the surface, it must be disconnected from the pipeline. It is important to check whether it is in working order, in this case, you can replace the connecting mechanism, check valve and clutch. The listed spare parts, most likely, during operation have lost the operating characteristics. Experts advise to install new ones. If the old installation is completely out of order and there is no way to repair it, new equipment should be installed.

Technology of work

The master should make the connection of the pipeline main line with the equipment, solder the power supply cable. It is important to ensure the tightness of the connection. After the safety rope is reinforced, its tension should be analyzed. The installation of a surface pump on a well is carried out practically using the same technology, but you do not have to use insurance. Once the borehole headband has been tightened, the fittings must be installed on the harness by setting the automation.

Cost per installation

If you install the pump in a well, the price for such services should interest you. When ordering the installation of such equipment from professionals, you will have to pay about 20,000 rubles. In different companies, the cost, of course, will be different. Some other factors are important, for example, the complexity of the work.
