介绍了卧式活塞推料离心机推料液压系统的结构和工作原理,针对其运行中存在的推料杆颤抖、停滞等质量问题,分析了产生的原因,提出了一系列改进措施。实践证明,改进后的液压系统工作正常,性能稳定可靠。 This paper introduces the structure and working principle of the hydraulic system of the pusher hydraulic system of the horizontal piston pusher centrifuge. In view of the quality problems such as trembling and stagnation of the pusher rod in its operation, the causes of the problems are analyzed and a series of improvement measures are put forward. Practice has proved that the improved hydraulic system is working properly, the performance is stable and reliable.
