Pumping equipment designed for installation in a well acts as an important element responsible for water intake. The functioning of the entire water supply system will depend on how correctly the equipment has been selected and installed. Before starting the installation of the pump, it is necessary to analyze the well for the absence of distortions or any kind of narrowing, which may have a casing. If such conditions exist, then it is necessary to be prepared for the fact that the installation will occur with some difficulties. It must be remembered that the life of the equipment will be significantly reduced. If the difference between the pipe diameters turned out to be quite impressive, then the device will not be able to cool properly. This will cause the pump to ignite. Experts emphasize that too small a difference can lead to problems that arise during the operation of the equipment. If you are interested in this question, then you can find out about the minimum acceptable indicators by looking at the technical documentation.
Installation of the pump in the well
Installation of the pump in the well should be done only after the cord or the team selects the cord to which certain requirements are presented. The rope must withstand a tensile load that is five times the mass of the device itself. Among other things, it is necessary to pay attention to what distance must be maintained in order to fix the suspension. Be sure to exclude the absorption of the site. To do this, it should be located no closer than 10 m from the inlet. If the installation of the pump in the well is accompanied by lowering the device to a more impressive depth, then a spring suspension is fixed at the end of the cable. This component will contribute to the damping of vibrations. As this element, a medical tourniquet can act.
Technological features of the installation
Installation of the pump in the well should not imply the use of a steel cable, which some masters use as a suspension. This rule should not be neglected for the reason that the metal element is able to break the mountings located on the pump casing. Withstanding a step in the range from 0.7 to 1.3 meters, it is necessary to strengthen the power cord, nylon suspension, and also the pipe (the latter should be made of metal plastic). To carry out these manipulations, use electrical tape. Having departed from a branch pipe about 20 cm, it is necessary to make one fastening.
How to avoid mistakes
Installation of the pump in the well should not imply the use of threaded connections to connect the device. Experts say that they can be susceptible to corrosion during operation. That is why it is recommended to use an alternative solution, involving the use of flange connections. In this case, the fixing bolt must be turned up, while the nut will look down. Thus, you will be able to prevent the bolt from falling into the well, which can happen by accident. If this cannot be avoided, then the well will be stopped.
Installation Recommendations
When the submersible pump is installed in the well, the upper part, which refers to the discharge pipe, must be well fixed to the base plate. Then you can begin installation work involving the use of a check valve. It is worth considering that this recommendation is true for all variations that are devoid of this component. To the crossbar you need to strengthen the suspension. It is important to exclude any contact of the surface of the pump casing with the walls of the well. If you are not sure that you can perform these manipulations without the interaction of materials, then you can play it safe by protecting the case using a rubber ring. The insulation resistance of the motor winding is determined by a pressure gauge. In the next step, it will be necessary to check whether the device is at a sufficient depth. After that, you can test how well the electric motor functions when it is under load.
About the depth of immersion
If you yourself decided to install the water pump in the well, then you need to think about the depth of its location. Installation of equipment is carried out 30 cm below the so-called dynamic level of water position. This indicator is minimal. Below the static level, raise the distance from the water mirror to the surface of the earth. After pumping water from the intake, measure the level at which the stop will be made. This position will become a dynamic level. The step from the pump to the bottom should be equal to the limit of 1 to 2 meters. This indicator can be increased. If the submersible pump will be installed in the well for the first time, then when choosing equipment it is necessary to pay attention to those models that have a float switch. If the water level in the well reaches the most critical level, then the float switch will perform its function by stopping the engine.
Reinstallation of the pump in the well
Do-it-yourself installation of the pump in the well can be done again. Such a need arises in some cases. Among them, one can single out the fall of equipment into the water intake. The most common cause is a break in the mounting cable. It may be necessary to replace the installation if the equipment modification is incorrectly selected. Quite often, purchased pumps have insufficient or, on the contrary, excessive power. This also applies to performance. Re-installation of the ECV pump in the well may be necessary if the operation or installation was carried out in violation of the rules and technology. Well owners are faced with the problem of voltage drop that occurs in the mains. This can also contribute to the need for equipment changes. Reinstallation of the water pump into the well is carried out when pulling the electric cable, as well as wedging equipment. If a break in the water-lifting pipe, slack in the cable, and groundwater fluctuations have been noticed, the equipment must be immediately removed and replaced.
Replacing a pump with a new one
You can carry out replacement work on your own or use the services of specialists. If you decide to carry out the work yourself, then you will need the help of several more people. One master will not be able to cope with the weight of 100 kilograms, which is possessed by equipment located at a depth of 50 meters. It will be required for manipulations and a safety cable. After removing the equipment, it should be checked for maintainability. If there is no chance to return the pump to work, then you need to purchase and install a new unit.
The order of work
Step-by-step installation of the pump in the well involves an initial disconnection of the equipment from the power supply. In the place where the pipe was connected, the fastening must be unscrewed. The old pump is removed slowly enough, while it is necessary to provide insurance with a cable. It is necessary to pull out the equipment continuously, with the help of three people. After removing the pump, you can begin to install a new one. Installation of a downhole pump in a well involves fixing the device to the pipe. It is necessary to connect a cable to the base, as well as solder the wires and install the fluid coupling. The wires are fixed to the pipe. The next step is to lower the device into the well. The electrical cable must be protected against rubbing at the edge.
Final work
Once the pump reaches the required depth, it should be tested by connecting to the electrical network. If the need arises, it will be necessary to carry out a reconfiguration of the automation. Installation of the deep pump in the well can be carried out independently, but experts recommend seeking professional help. Among other things, this approach is more acceptable also for the reason that a team of professionals guarantees a successful outcome.
