How to Select Submersible Pumps?

Submersible pumps for well use are essential equipment for deep well water extraction, and they are crucial in providing our source of life. The selection method for well submersible pumps is "determine the pump by the well." The flow rate of the selected well submersible pump must not exceed the涌水流量 of the well. If the flow rate of the selected well submersible pump is too small, it cannot fully utilize the benefits of the well. Conversely, if the flow rate is too large, it will cause a significant drop in the dynamic water level in the well, increasing the pressure difference between the inner and outer walls of the well. The increased inflow velocity against the well wall can lead to a large amount of sand surge, causing clogging in the intake pipeline and sedimentation within the well, shortening the well's lifespan and potentially leading to wall collapse and the abandonment of the well. Therefore, the flow rate of the selected well submersible pump should be less than or equal to the well's water inflow.
