The article analyzed reason that current centrifugal liquid charge pump solve the difficulty of mud leaking,then it points out that the main failure of pump seal is caused by the disalignment of pump shaft rotating centerline with the centerline of shaft inner bore centerline and abrasive grain.
分析了现用离心式灌注泵难以解决泥浆泄漏的原因,指出了泵轴旋转中心线与轴封内孔中心线不重合和泥浆内含有磨砺性固相硬颗粒是引起径向接触式软填料密封失效的主要原因。
The PCP system is comprised of a water injection pump, a liquid charge pump, variable-frequency speed regulating system, computer-aided control system, instrument monitoring system, lubricating system and cooling system.
PCP系统由 1台注水泵、 1台灌注泵、变频调速系统、计算机控制系统、仪表监测系统、润滑系统及冷却系统组成 ,其中注水泵是整个泵站系统的核心。
