Single screw is to press rotary mesh displacement working principle of new type of pump, the main working parts is eccentric screw (rotor) and fixed bush (stator).
Because the two parts of the special geometry, which form a separate seal let cavity, medium by axial uniform implementation of the flow, the internal flow rate is low, the volume remains unchanged, the pressure stability, and won't produce eddy current and agitation. Every stage pump output pressure is 0.6 MPa, head *0 m (water), self-priming height is in commonly 6 m, it is suitable for conveying medium temperature below *0 °C (special request can reach **0 °C).
For stator a variety of elastic materials, so this kind of pump of high viscosity fluid conveying and contains hard suspended particle medium or contain fiber media delivery, general pump is unserviceable characteristics. The flow and speed is proportional.
Drive can use coupling direct drive, or use the speed regulating motor, triangle belt, transmission device such as variable speed.
This kind of pump parts less, compact structure, small volume, simple maintenance, rotor and stator is the pump of wearing parts, the structure is simple and convenient, easy to put down.
