降低大功率液压泵启动扭矩的方法研究

Method Research on Decreasing Startup Torsion of High-power Hydraulic Pump

针对某型号钻机液压系统的设计,对比目前广泛运用的负荷传感降低大功率液压泵启动扭矩技术,设计采用了一种新型的大功率液压泵低扭矩启动的方法。它具有结构简单、可靠性高和成本低的特点。

Based on the hydraulic system design of one type of borers, comparing to the load - sensing technology, a new method of decreasing startup torsion of high - power hydraulic pump is adopted. It is simple, reliable and cheap.
