How to use the pump to maximize the effectiveness of it? If the use of unreasonable will shorten the life of the pump, so the correct use of the method is to extend the pump life, reduce economic losses, an important factor. First, for the submersible pump, start before doing some necessary checks: the rotation of the pump shaft is normal, there is no stuck phenomenon; impeller position is normal; cable and cable plug without rupture, abrasions and broken phenomenon . Operation should pay attention to observe the voltage changes, the general control of the rated voltage within ± 5%. In addition, the location of the pump in the water is very important, should be selected as much as possible in the water, silt-free, good water quality, vertical suspension in the water, not allowed to cross, so as not to fall into the mud or suspended matter blocked by the pump inlet, and Lead to sharp drop in water or even pumping to the water. Second, for the self-priming pump, should be placed in a well ventilated place to run, in order to facilitate rapid cooling, reduce the motor temperature. Otherwise, prolonged operation, easy to burn the motor. If a farmer is using a self-priming pump, the motor is overheated and the coil burned out because the plastic film covering the motor is not removed. In addition, before starting, be sure to check the pump body of water, otherwise, not only affect the self-priming performance, but also easy to burn shaft seal components. Under normal circumstances, the pump should be 3-5 minutes after the start of water, or should immediately stop checking. Third, when the pump fails, should not disassemble yourself. Because of their demolition, I do not know where the fault is caused by blindly dismantling a pass; Second, there is no special tools and often damage the original parts intact. The best way is to have the experience, the maintenance of scale maintenance, and timely replacement of "over age" parts and some wearing parts. Under normal circumstances, the pump should be repaired once every six months, to eliminate "sick" work. Fourth, in non-use period, the pump should be promptly removed from the water, and empty the pump water, especially in the cold winter. Then place it in a dry place, conditional users can also apply butter in the key parts of the pump, add lubricant to the bearings to prevent corrosion of parts. In addition, the non-use of the pump, not the longer the better. If you do not use for a long time, not only easy to rust parts, but also reduce the service life of the pump. How to maintain the pump 1 Always check whether the lack of oil bearing is working properly 2 Coupling is normal 3 Whether the suction pipe leakage Leakage 4 Balance tube is blocked 5 The water pressure is normal 6 Whether the vibration is too large 7 Bearing base is overheated 8 Manual crank is flexible 9 Pump base is solid 10 Packing with a seal often add fastening replacement sleeve
