Deep well submersible pump manufacturers tell you how to pick deep well pumps

Deep well pump huge production needs to stimulate the birth of a large number of deep well pump enterprises, the market deep well pump brand varies greatly, coupled with the deep well pump working environment is different, how can we pick a suitable deep well pump? Selection will be greatly improved work efficiency, selection of mistakes, not only can not play its effectiveness, but also increase production costs. So in the selection of deep well pump should be considered in the following aspects.
Deep well submersible pump manufacturers tell you how to pick deep well pumps
According to the allowable exploitation amount of the water source well, the deep well submersible pump is selected, and the specifications and models of the deep well submersible pump are determined according to the water level of the water source well to determine the reasonable structure of the water source well.
2, the diameter of the deep well pump must be consistent with the diameter of the wellbore. In order to make the deep well pump from the smooth, groundwater when the space can be quickly pooled, no resistance can reduce the pump running wear and tear, requiring the water pipe and pump parts of the well diameter is greater than the maximum diameter of the pump 20 ~ 40 mm, That is, the maximum diameter of the pump body and the annular wall between the ring gap should be 10 ~ 20 mm, in order to extend the wells and deep well submersible pump life;
3, according to the total loss of pressure to choose deep well pump. The diameter, head (series) and power of the deep well submersible pump are selected according to the total loss of the required pressure head from the pump head to the ground pool or water tower according to the deep well submersible pump. The water pressure increases with the number of impellers. Deep well pump impeller immersed in water work, only the head without suction. Rated head and pump actual running head, can not be too much difference, absolutely can not be higher than the actual head of 25%. The pump head is high, the required motor power, easy to cause the pump has a larger string, the light wear the impeller and the leaf shell, heavy in the shell of the bearing (from the limit role) easy to stick with the pump coupling, Causing the pump can not run, the motor overload winding will burn out.
4, according to the maximum allowable exploitation of water wells to select the multi-stage diving pump. The pump pump must be consistent with the actual amount of water in the wells, the pump must be equal to or slightly less than the actual amount of water wells, or will inevitably produce strong pumping, not only will shorten the life of the deep well submersible pump, Network destroyed, resulting in more than sand, and even cause the wells scrapped.
5, deep well pump pump downhole position Deep well submersible pump pump head, absolutely not in the filter tube (flower tube) position, must be in the wall tube (tube) position, otherwise pumping will be more than sand or The wells are destroyed. According to the electrical survey curve of the probe, the two sides, according to the well and adjacent water source of the hydrogeological conditions (aquifer depth, aquifer thickness, aquifer lithology) and the pump operation, The well of the well structure (well diameter, flower tube, solid pipe position) and well depth and pump selection to ensure that the future, the next pump and pump operation process, without any problems.
