Pump

潜油泵CentrifugalPumpsTheREDApumpisamultistagecentrifugalpump,containingaselectednumber(applicationdependent)ofimpellersequippedwithvanes,insideacloselyfitteddiffuser,locatedinseriesanaxialshaft,drivenbytheelectricalmotor.

雷达潜油泵是一种多级离心泵。泵由很多级带有叶片的叶轮及导壳紧密配合以串联方式安装在泵轴上。泵是由电机驱动。Each“stage”consistsofanimpellerandadiffuser.

每一泵级由一个叶轮和一个导壳组成。Acentrifugalpumpcreatespressurebytherotationofaseriesofvanesinanimpeller

离心泵是通过转动叶轮中一系列叶片产生压力
