Today, an increasing number of citizens change their place of residence to suburban settlements. This is not only prestigious, but also nice. In addition, for health such a lifestyle is very useful. However, habitat change sometimes involves interruptions to electricity and water extraction from a nearby column. It is quite difficult to find a place for a well independently, and it is dangerous for life to make its excavation. It is best to contact specialists who will do the job for you in a short time and will also 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.
If the pumps are to be installed, it should first be checked whether the casing has any constrictions, irregularities or other distortions. If such circumstances occur, it can significantly complicate installation, and also reduce the life of all equipment. Installation of deep pumps should assume the difference between the diameters that are characteristic of the pipe and the pump. If it turns out to be too small, the existing surface defects will act as a problem when working, if this parameter is too large, the pump may burn up completely. This can be explained by the fact that in the latter case, it is impossible to provide the speed of water movement, which is required in order for intensive and proper cooling of the engine to occur. The pumps must only be installed after you have been able to determine the permissible value for the difference in diameters. You can find out by looking at the technical documentation.
What is important to know before installing
The installation of pumps must not be done independently unless you are confident in your own skills and knowledge. However, if you decide not to use the services of professionals, then the pump should be suspended on a nylon cord, the latter must withstand the tensile load, which exceeds the weight by at least 5 times. It is important to exclude the effect of suction of the assembly on which the suspension is fixed, it should be tied at 10 centimeters from the inlet openings. This indicator is minimal. Then the ends should be scorched. If the pump is to be lowered by less than 10 cm, a spring suspension should be attached to the end of the cord, it will allow the vibration to be extinguished. To do this, you can purchase a medical tourniquet, but flexible rubber is also suitable.
Advice of an experienced master
Installation of pumps is never done using iron wire. It is inadmissible to use a cable, which some domestic masters use as a suspension. This rule is due to the fact that this approach can damage the mounts that are located on the aluminum casing of the equipment being installed. Using insulating tape, it is necessary to fix a nylon suspension, a metal-plastic pipe, and also a power cord. Mounting is installed at a distance ranging from 70 to 130 cm. The first bunch is located 20 centimeters from the pump branch.
Recommendations for commissioning
Installation of the pump, the price for which can reach 20,000 rubles, is often produced independently, while the owners of private houses try not to resort to qualified assistance. If you decided to approach the solution of this issue, limiting yourself, then you should first thoroughly 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 discarded, as this can reduce the strength of pipes that are corroded. When a downhole pump is installed, experts advise the use of flanged connections that can last much longer. Their use involves the installation of the mounting bolt exclusively from the top, while the bottom should be located nut. Do not reinforce the bolt at the bottom, since if it falls into the well, it will cause a serious accident. To the base plate should be strengthened the discharge pipeline, or rather, only its upper end. Then a check valve is installed to the base plate, which is the case if the pump is devoid of such an element. Further, the knee, the bolt, and also the manometer are strengthened. After carrying out these manipulations, you can connect the pump to the water supply system.
Features of work
Installation of the pump, the price for which was indicated above, provides for the next stage to strengthen the suspension to the crossbar. This manipulation is the last before the pump is lowered into the well. When the equipment is placed inwards, contact with the walls should be avoided. If you can not guarantee this by 100%, then the body is recommended to protect beforehand using a rubber ring. The installation of a downhole pump involves measuring the water level that is in the well. For this purpose, a gas pipe string should be installed in the hole that is located on the base plate. It should be loaded to such a depth that it is below the dynamic level. The megaohmmeter will allow analyzing the insulation resistance of the motor winding with the cable lowered. Then you have to connect the control station to the pump itself. The master must analyze whether the immersion in water has been made sufficiently. At the same stage, it is estimated how well the engine is operating under the workload.
Pump immersion depth
Installation of water pumps requires the correct determination of the level of immersion. Before this, it is important to decide what the static level is. This is the length of the segment from the level of the surface of the earth to the mirror of water, when the latter is in its natural state. After that, water can be pumped out of the well. The received level at which water will stop is called dynamic.
In order for the motor to cool properly, the pump must be immersed 30 cm below the dynamic level. And this indicator is minimal. As the optimal level of immersion, they are 2 meters below this mark. In this case, the master should remember that the distance to the bottom should be equivalent to one meter or more.
Work to install a new pump after an accident
Installation of the pump in the well may be required also when an accident or failure of old equipment has occurred. This need, it must be admitted, is rare. As a rule, this is due to the fact that the pump was incorrectly installed in the well at the initial work. The cause of the accident can be hidden in the automation system, which was selected illiterately. In some cases, an accident occurs because of the low power of the pumping equipment. As an example, you can consider a pump, which is calculated by the manufacturer for a dip of 50 meters. If you close the equipment by 80 cm during installation, the repair will be necessary after several months of operation. The pump must only be installed in the well after the automatic power supply has been adjusted to the water pressure maintained by the equipment. From the above-mentioned depth, the equipment shown in the example will not be able to raise water. As a result, the pump will operate smoothly for a long time. In the end, you will come across a problem with the installation failure. In this case, one can resort to one of two solutions. The first involves calling specialists, while the other involves conducting all the work independently.
Pros of solving the problem by a team of professionals
If the installation of the submersible pump is carried out by specialists in their field, they will be able to objectively assess the current situation, as well as to identify the reasons that led to a malfunction in the pump. Agree, you can not determine on your own whether the automation and the pump itself worked correctly. A situation may arise that the pump did not fail, while the automation failed. In this case, it will be enough just to make the adjustment.
Installation of the submersible pump by specialists has one more plus, which is expressed in the fact that the company gives a guarantee for the work. In addition to the basic manipulations, the contractor performs the adjustment of the water supply system.
Self-replacement of pumping equipment
Re-assembly of water supply pumps should only be carried out 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 because the suspension, cable and pump have an impressive weight at a depth of 100 meters. We will have to work with a mass of 250 kilograms. Initially, prepare a metalwork tool, supplies, scissors, a construction hair dryer, a soldering iron, a shrink sleeve. In the next step, disconnect the well head pipe and the equipment power cable from the line. After the latching element is removed. As soon as the pumping equipment is lifted up, it should be disconnected from the pipeline. Installation of a surface pump, as well as a submersible pump, involves inspecting the equipment to check whether the installation is in working order.
Replacement of worn pump parts
Experts advise changing the equipment to replace the coupling mechanism, the coupling, and also the non-return valve. The listed components most often lose their quality characteristics in the process of operation. Installation of deep pumps involves connecting the pipeline with the equipment, then the power cable is soldered. It is important to ensure maximum tightness of the connection. Do not forget about the safety rope, the stretch of which should be checked before the moment of immersion. Only after you can start installing the pump.
