The basic working principle of screw pump
Due to the intermeshing of the screws and the close fit of the screw with the inner wall of the liner, it is separated into one or more sealing spaces between the suction and discharge ports of the pump.
The threads of the active screw driven screw are double-headed threads.
In the figure, the middle screw is the active screw, driven by the prime mover, and the screw on both sides is the driven screw, and the active screw is rotated in the reverse direction.
In the figure, a cross-sectional view of the three-screw pump is shown.
1. Screw pump is the use of screw rotation to suck the liquid.
