Background

The submerged pump is a single screw type transport pump, and its main working components are screw of eccentric spiral body (called rotor) and screw bush whose inner surface is made into double-line spiral surface (called stator). The working principle is that when the motor drives the pump shaft to rotate, the screw rod rotates around the axis of the screw rod, and rolls along the inner surface of the lining, so that a sealed chamber of the pump is formed. The liquid in the sealing cavity advances by a screw pitch in each rotation of the screw, and the liquid is pressed from one sealing cavity to the other sealing cavity in a spiral mode along with the continuous rotation of the screw, and finally the pump body is extruded.
