Installation of the pump in the well can be done independently. This will allow residents of country houses and owners of summer cottages to use clean drinking water, which can be produced without interruption and with ease.
Mounting technology
Before starting the installation of the pump, it is necessary to analyze whether there are any distortions, narrowing or unevenness of the casing. Such problems can complicate the installation, as well as significantly reduce the life of the equipment. Installation of a vortex pump in a well should be made taking into account the difference between the diameters of the pump and pipe. If it is too small, existing surface defects can adversely affect work. Whereas if the difference is too large, the pump may burn out. In the latter case, the required water velocity, which is required to cool the engine, will not be provided. The minimum permissible indicators should be indicated in the technical documentation. Installing a pump in a well involves suspending the equipment on a nylon cord that will be able to endure a tensile load (it should exceed 5 times the weight). In order to exclude the suction of the unit on which the suspension is fixed, it should be tied up, deviating from the inlets at least 10 centimeters. As for the ends, they should be scorched. If the equipment is supposed to be lowered less than 10 meters, an additional spring suspension must be fixed at the end of the rope, it must dampen the vibration. To do this, you can use a flexible rubber tape or medical plait.
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 as a suspension. This is due to the fact that these materials during operation are able to break the mounts that are located on the aluminum case of the equipment.
What is important to know
The nylon suspension, power cord, and also the plastic metal pipe must be fixed with electrical tape, observing a step within 130 cm. The first bundle must be removed from the pump nozzle by 30 centimeters.
Connectivity
When the centrifugal pump is installed in the well, you will not have to use threaded connections when connecting. They can reduce the strength of pipes that corrode. Longer life span are flange connections. When using them, the fixing bolt must be installed on top, while the nut is fixed on the bottom. This is because a fallen bolt can cause serious accidents. On the base plate, you need to fix the discharge pipe, or rather, its upper end. At the next stage, a check valve is mounted on it if the pump is devoid of it.
At the same stage, the elbow, gate valve and pressure gauge should be connected to the water supply system. Now the suspension is fixed to the crossbar. This is the last thing to do before the pump is in the well. Installation of a surface pump in a well involves the process of lowering equipment that should not touch the walls. If this possibility cannot be ruled out, it is recommended to protect the case with a rubber ring. To measure the water level in the well, it is necessary to mount a column of gas pipes, which is installed in the hole of the base plate. It must be loaded below the dynamic level.
With a megger it will be possible to determine the insulation resistance of the motor winding with the cable down. Then you should connect the control station to the equipment, checking whether the pump is sufficiently submerged in water. Installing a pump in a well, the price of which will be indicated below, requires the assessment of the correct functioning of an electric motor under the load.
Determining the depth of the pump
If you yourself will be installing the deep pump in the well, then it is important to think about how deep 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 the water stops is called dynamic. In order for the engine to cool properly, it is necessary to lower the equipment 30 cm lower in relation to the dynamic level. As the most suitable deepening, a dive 3 meters below the mentioned mark is taken. It must be remembered that the distance to the bottom of the well should be equal to two meters.
Pump installation in the event of an accident
Installation of a downhole pump in a well is sometimes carried out after an accident. Such a need appears rarely enough, as a rule, this happens because the installation technology was not observed the previous time. The cause of the accident may lie in improperly selected power automation, the problem may lie in the low power of the equipment itself. Thus, if the pump is designed for immersion to a depth of 50 meters, and it was deepened to 80 meters, then repairs will be required after several months of operation. The power automation is designed for the working pressure of the water, while from the wrong depth a sufficiently weak pump will not be able to lift the liquid up. Ultimately, the installation will work continuously, which will cause a quick failure.
Self-replacement pump
Reinstallation of the submersible pump in the well can be carried out both independently and with the help of specialists. If the first option is the most acceptable for you, then first you need to make sure that the equipment is working. If you decide to independently carry out such work, then you should enlist the help of five people. This is due to the fact that you will have to work at a 100-meter depth, and the cable, suspension and pump will have a weight equal to about 250 kilograms. Initially, you need to prepare a bench tool, a heat shrink sleeve, an electric soldering iron, supplies, a building hair dryer, and scissors. At the next stage, you need to disconnect the line that goes into the house from the well head. Among other things, disconnect the equipment power cable. Now the tightening element can be unscrewed.
Some nuances of work
Installation of a submersible pump in a well must be accompanied by the use of a safety cable, which is used when lifting old equipment. This requirement is due to the fact that the pump cable can break, and it will be impossible to lift it. Ultimately, this will lead to the fact that it will not be possible to use the well in the future. After the pump is raised to the surface, it must be disconnected from the line. It is important to check whether it is in working condition, in this case, you can replace the connecting mechanism, non-return valve and coupling. The listed parts are likely to have lost their performance characteristics during operation. Experts advise installing new ones. If the previous installation is completely out of order, and there is no way to fix it, then new equipment should be installed.
Technology of work
The master must connect the pipeline main to the equipment, solder the power supply cable. It is important to ensure tightness of the connection. After the safety cable is strengthened, its tension should be analyzed. Installation of a surface pump in a well is carried out practically using the same technology, however, you do not have to use insurance. Once the borehole head is tightened, fit the fittings to the harness by completing the automation settings.
Installation Price
If you will install a pump in a well, the price for such services should be of interest to 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.
