What are the differences and connections between long shaft pumps and deep well pumps
Long shaft pump:
The long shaft pump is a vertical single suction centrifugal pump, with its impeller installed below the dynamic water level in the well, and the power machine set on the well. The impeller is driven by the long shaft to rotate inside the guide shell, and the water flows along the flow channel between the guide shell and the impeller, and is lifted up to the ground through the water delivery pipe. When the head is high, a multi-stage centrifugal pump with multiple impellers in series can be used. Due to the high precision requirements for the manufacturing and installation of the transmission long shaft, the efficiency significantly decreases with the increase of well depth, so it is generally only used for deep wells not exceeding 100 meters.
Deep well pump:
It is a pump that is immersed in underground water wells for pumping and transporting water, and is widely used in agricultural drainage and irrigation, industrial and mining enterprises, urban water supply and drainage, and sewage treatment. Due to the simultaneous submergence of the electric motor into the water, the structural requirements for the electric motor are special compared to general motors. The structural forms of its electric motor are divided into four types: dry, semi dry, oil filled, and wet.
The difference between long shaft pumps and deep well pumps: long shaft pumps are separated, while deep well pumps are integrated. The connection between long shaft pumps and deep well pumps: both are used to pump underground well water.
