注聚泵液力端的改进设计

Abstract For the purpose of improving the service life and working performance of polymer injection pump's wearing parts this paperhas analyzed the polymer's flow characteristics and problems in usage and has come up with the improved program of polymer injectionpump hydraulic end by investigating the polymer injection pump usage in oilfield. Hydraulic end reduces the degradation of the polymer andit's diversion is good with a diversion-type valve.院注聚泵 液力端 改进设计Key words polymer injection pump hydraulic end improved design中图分类号院TE926 文献标识码院A 文章编号院1006-4311（2014）06-0053-02榆漏失较严重等。
