The screw pump uses the rotation of the screw to suck the liquid. The middle screw is an active screw, which is driven back by the original motivation. The screw on both sides is the motorized screw, and the active screw is rotated in the reverse.

Each screw is messed with each other, and the screw and the inner wall of the lining tube are closely matched. Between the inlet and outlets of the pump, they will be separated into one or more sealing spaces. With the rotation and meshing of the screw, these sealing spaces are constantly forming at the absorbing end of the pump. The liquid in the inhaled room is seized into it, and the self -suction room is continuously moved to the axial of the screw to the discharge end. The liquid is constantly discharged. This is the basic working principle of the screw pump.

It can be seen from the above working principles that you can understand the advantages of the screw pump more clearly:

The range of pressure and flow is wide; the types and viscosity range of the transportation liquid are wide; because the rotation parts in the pump are low, they can use a high speed; good inhalation performance, self -suction ability; uniform flow continuous flow, small vibration, small vibration, small vibration, small vibration, and small vibration, and small vibrations, vibrations, and small vibrations. Low noise; compared with other rotating pumps, it is not very sensitive to the entry gas and dirt; the structure is solid, and it is easy to install and maintain.
