Today, an increasing number of city dwellers are changing their place of residence to suburban settlements. It is not only prestigious, but also pleasant. In addition, this lifestyle is very beneficial for he alth. However, a change in habitat sometimes involves power outages and getting water from a nearby well. Finding a place for a well on your own is quite difficult, and digging it out is completely life-threatening. It is best to turn to specialists who will perform this work for you with high quality and in a short time, as well as install a surface pump. Professionals will be able to determine whether it is possible to drill a well and install a pump on the site, if this option is the most suitable for a particular situation.
Installation recommendations
If pumps are being installed, the casing should first be checked to see if the casing has any narrowing, unevenness or other distortion. If such circumstances exist,this can greatly complicate the installation, as well as reduce the life of the entire equipment. The installation of deep-well pumps should involve determining the difference between the diameters that are characteristic of the pipe and the pump. If it turns out to be too small, then the existing surface defects will act as a problem during operation, but if this parameter is too large, then the pump may even burn out. This can be explained by the fact that in the latter case it is impossible to ensure the speed of water movement, which is required for intensive and proper cooling of the engine. Pumps should only be installed after you have determined the allowable difference in diameter. It can be found by looking at the technical documentation.
What you need to know before installing
Installation of pumps by yourself should not be done if you are not confident in your own skills and knowledge. However, if you decide not to use the services of professionals, then the pump should be hung on a nylon cord, the latter must withstand a tensile load that exceeds the weight by at least 5 times. It is important to exclude the suction effect of the knot on which the suspension is attached, it should be tied 10 centimeters from the inlets. This figure is the minimum. Whereas the ends should be singeed. If the pump is supposed to be lowered less than 10 cm, then a spring suspension should be attached to the end of the cord, it will dampen the vibration. To do this, you can purchase a medical tourniquet, but flexible rubber is also suitable.
Advice from an experienced master
Pumps are never installed with iron wire. It is also unacceptable to use a cable, which is used by some home craftsmen as a suspension. This rule is due to the fact that with this approach, it is possible to damage the fasteners that are located on the aluminum case of the installed equipment. Using electrical tape, a nylon suspension, a metal-plastic pipe, and a power cord should be fixed. The mount is installed at a distance ranging from 70 to 130 cm. The first bundle is located 20 centimeters from the pump nozzle.
Commissioning recommendations
Installation of the pump, the price of which can reach 20,000 rubles, is often done independently, while the owners of private houses try not to resort to qualified help. If you decide to approach the solution of this issue, limiting yourself, then initially you should carefully familiarize yourself with the technology. This also applies to commissioning. Connection of the pump to the well should not involve the use of threaded connections. They should be abandoned, as this can reduce the strength index of pipes that are subject to corrosion. When a borehole pump is being installed, experts in their field advise using flange connections that can last much longer. Their use involves the installation of a mounting bolt exclusively from above, while from belownut must be in place. It is not necessary to strengthen the bolt at the bottom, because if it falls into the well, this will cause a serious accident. The injection pipeline, or rather, only its upper end, should be strengthened to the base plate. Then a check valve is installed to the base plate, which is true if the pump is devoid of such an element. Next, the knee, the valve, as well as the pressure gauge are strengthened. After carrying out these manipulations, you can connect the pump to the water supply system.
Features of the work
Installation of the pump, the price of which was indicated above, provides for the next stage of strengthening the suspension to the crossbar. This manipulation is the last one before the pump is lowered into the well. When the equipment is placed inside, contact of the case with the walls should be avoided. If you cannot guarantee this 100%, then it is recommended to pre-protect the case using a rubber ring. Installation of a borehole pump involves measuring the level of water that is in the well. To do this, a column of gas pipes should be installed in the hole, which is located on the base plate. It should be immersed to such a depth that it is below the dynamic level. A megohmmeter will allow you to analyze the insulation resistance of the motor winding with the cable lowered. Then you have to attach the control station to the pump itself. The master must analyze whether the immersion in water has been carried out sufficiently. At this stage, it is assessed howengine functions well under work load.
Pump immersion depth
Installation of water pumps involves the correct determination of the level of immersion. Before that, it is important to define what a static level is. This is the length of the segment from the level of the earth's surface to the water table, when the latter is in its natural state. After that, water can be pumped out of the well. The resulting level at which the water stops is called dynamic.
In order for the electric motor to cool properly, the pump must be immersed to a mark of 30 cm below the same dynamic level. Moreover, this indicator is minimal. The optimal level of immersion is 2 meters below the mentioned mark. In this case, the master should remember that the distance to the bottom should be equivalent to one meter or more.
Working to install a new pump after an accident
Installation of the pump in the well may also be required when an accident occurs or the old equipment fails. Such a need, it must be admitted, arises quite rarely. As a rule, this happens due to the fact that the pump was incorrectly installed in the well during the initial work. The cause of the accident may lie in the automatic power supply, which was selected illiterately. In some cases, an accident occurs due to the low power of pumping equipment. As an example, considerpump, which is designed by the manufacturer to dive to 50 meters. If, during installation, the equipment is deepened by 80 cm, then repairs will need to be carried out within a few months after operation. The installation of the pump in the well should be carried out only after the automatic power supply is set to the water pressure maintained during the operation of the equipment. From the depth mentioned above, the equipment shown in the example will not be able to lift water. The result will be that the pump will continue to work smoothly for a long time. In the end, you will run into the problem of a broken installation. In this case, you can resort to one of two solutions. The first involves calling in specialists, while the other involves doing all the work yourself.
Pros of solving a problem by a team of professionals
If the installation of a submersible pump will be carried out by specialists in their field, they will be able to objectively assess the current situation, as well as identify the causes that led to the failure of the pump. You must admit that you cannot determine on your own whether the automation and the pump itself worked correctly. A situation may arise that the pump has not failed, while the automation has failed. In this case, it will be enough just to make the settings.
Company guarantee
Installation of a submersible pump by specialists has another plus, which is expressed in the fact that the company gives a guarantee for the work. In addition to the basic manipulations, the contractor sets up the water supply system.
Self-replacement pumpequipment
Re-installation of water supply pumps should only be done when you are sure that the equipment is faulty. It is important to enlist the help of a few more people before starting work. This is due to the fact that the suspension, cable and pump have an impressive weight at a depth of 100 meters. You will have to work with a mass of 250 kilograms. Initially prepare a metalwork tool, consumables, scissors, a building hair dryer, a soldering iron, a heat shrink sleeve. At the next stage, the well head pipeline and the equipment power cable should be disconnected from the main. After that, the tightening element is removed. As soon as the pumping equipment is lifted up, it should be disconnected from the line. Installation of a surface pump, like a submersible pump, involves an inspection of the equipment in order to check whether the installation is in working condition.
Replacing worn pump parts
Experts advise when changing equipment to replace the connecting mechanism, clutch, and check valve. These components most often lose their quality characteristics during operation. Installation of deep pumps involves connecting the pipeline to the equipment, then the power cable is soldered. It is important to ensure maximum tightness of the connection. Do not forget about the safety cable, the tension of which should be checked even before the dive. Only then can you proceed with the installation of the pump.
