What are the screw pumps of Lanzhou Naichi Pump Industry Co., Ltd.?

1. Screw pump: Screw pump is a new type of pump that works according to the principle of rotating meshing volume. Its main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometric shapes of the stator and rotor, independent sealed cavities are formed respectively, so that the medium is uniformly pushed to flow axially, the internal flow rate is low, the volume is constant, the pressure is stable, and vortex and agitation are not generated.

2. Rotor pump: Rotor pump is a form of positive displacement pump. It consists of a rotating rotor and a stationary pump body, and there is no suction valve and discharge valve. The working volume is changed by the relative movement between the rotor and the pump body, and the liquid is discharged by the extrusion of the rotating rotor, leaving a space at the other side to form a low pressure, so that the liquid can be continuously inhaled.
