Abstract：The paper introduces the design and technique of the screw pumps. In order to improve the service life of the screw pump,the working principle and factors affecting the service life of the screw pump are studied. The new rubber in a screw pump stator and the optimum design method of screw pumps at home and abroad in recent years are summarized. Applying the composite material mainly including silicate mineral and acrylonitrile-butadiene rubber,the activating silicate mineral nanometer complex material with good properties are developed,the properties of this material are better than that of carboxyl acrylonitrile-butadience rubber and all-purpose acrylonitrile-butadience rubber.
