Characteristics of deep well pump

Characteristics of deep well pump
1, deep diving
For the continuous access to groundwater resources or access to a deeper level of high-quality groundwater, wells with submersible pumps are generally placed tens of meters underwater, or even more than 100 meters deep water lift operations, subject to several or even a dozen atmospheric pressure, and With the increase in the depth of the pump placement, the pressure will be more and more. High-pressure environment on the motor sealing performance, parts of the anti-deformation, heat dissipation and parts design and manufacturing accuracy, reliability and other aspects have a higher demand.
2, high head
In order to meet the technical requirement of deep well water pumping, the head of submersible deep well pump is high. According to the national standard of "Submersible Pump for Well" (GB / T2816-2002), the lift range is 14 meters to 598 meters. In order to achieve high head, well submersible pump is generally multi-stage pump structure, the axial length is longer, resulting in a large axial force pump, how the integrated use of structural design and material selection to improve single-stage head, Axial force and radial concentricity control, determines the well with a submersible pump design and production more difficult.
3, the structure of special, radial size and overall small footprint.
