Analyses on Improving the Life of the Screw Pump's Stator Rubber

介绍了采油螺杆泵的结构和工作原理。针对提高采油螺杆泵工作寿命的问题,通过对螺杆泵工作原理和工作寿命影响因素的分析,框述了近年来国内外螺杆泵定子橡胶新材料的特点和螺杆泵结构的优化设计方法,研究并采用了活化的硅酸盐矿物与以丁腈橡胶为主要成分的复合材料,来制备出高性能的活化硅酸盐复合材料。该材料的各项性能均高于羧基丁腈橡胶及通用丁腈橡胶。

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.
