stainless steel single screw pump is a single-screw transport pump, its main working parts are eccentric screw (rotor) of helix and the inner surface is on the surface of the double spiral screw bushing (called stator).stainless steel working principle of single screw pump is when the motor drives the pump shaft rotation, screw around the axis of rotation itself on the one hand, on the other hand it along the bushing inside surface rolling, then form the pump seal chamber.screw each week, liquid sealed cavity forward a pitch, with continuous rotation of the screw, liquid spiral way from a sealed cavity pressure to the other a sealed cavity, finally out of the pump body.single screw pump is a new type of fluid conveying machinery, has a simple structure, safe and reliable work, convenient operation and maintenance, the fluid continuous uniform, stable pressure, etc.a use of the rotation of the screw to absorb liquid pump, it is most suitable for suction row of viscous liquid.single screw pump has the following advantages:
