How to choose deep well pump? Analysis of deep well pump selection method

The huge production needs to stimulate the birth of a large number of deep well pump companies, the market deep well pump brand mixed, coupled with deep well pump working environment is different, how to pick a suitable deep well pump? Proper selection will greatly improve work efficiency, selection mistakes, not only can not play its effectiveness, but also increase production costs. So in the selection of deep well pump should consider the following aspects. 1, According to the allowable production of water source wells, deep well submersible pumps are selected to determine the specifications and types of deep well submersible pumps under the conditions of hydrogeology and according to the inflow of water from the water wells, so as to determine the reasonable structure of water wells; Deep well pump? 2, deep well pump diameter and well diameter must be consistent. In order to make the deep well pump go smoothly, pumping groundwater has space to collect quickly, without resistance but also reduce the pump running wear and tear, requiring the pumping pipe and pump body parts of the borehole diameter greater than the maximum diameter of the pump 20 ~ 40mm, That is, the maximum diameter of the pump body and the annular wall between the annular gap to have 10 ~ 20 mm, can extend the life of wells and deep submersible pumps; 3, according to the total loss of pressure head selection deep well pump. The diameter, head (series) and power of the deep well submersible pump are to be selected based on the total head pressure required for the submersible pump to deliver groundwater from the pump head to the surface pool or tower. Pressure increases with the number of impeller flow increases. Deep well pump impeller immersed in water work, only lift without suction. Rated lift and pump actual lift, can not be much difference, absolutely can not be higher than 25% of the actual lift. High pump head, the required motor power, likely to cause a larger pump on the string, the lighter wear impeller and leaf shell, heavy shell bearings (from the limit role) easy to stick with the pump coupling, Cause the pump can not operate, the motor overload winding will burn out. 4, according to the maximum allowable exploitation of water wells to select multi-stage diving pump. The pump volume of the pump must match the actual water volume in the well. The pump volume must be equal to or slightly less than the actual production volume of the water well. Otherwise, strong pumping will inevitably occur. This will not only shorten the service life of the deep well submersible pump, Network destroyed, resulting in more than gushing sand, or even cause the wells scrapped. 5, the deep well pump head down well position Deep well submersible pump head, must not be under the filter tube (flower tube) position, must be under the shaft wall tube (tube) position, or pumping more grit sand will or will Water well clumsy. According to the electric test curve of the hole, according to the hydrogeological conditions (the depth of the aquifer, the thickness of the aquifer, the aquifer lithology) and the operation of the pump according to the well and the adjacent well, Well completion structure (well diameter, flower pipe, pipe position) and well depth and pump selection to ensure that the next pump and pump operation, without any problems. In summary, different environments, the use of deep well pump is not the same. Therefore, the choice of deep well pump must be clear before deep well pump working environment.
