摘　　要：液压马达平衡回路在制动过程中,马达回油腔的压力与负载的质量、回油腔的容积和马达开始制动时负载的运动速度有关。带有大惯量的液压马达平衡回路如果在较高的速度下制动,将在马达回油腔形成过高的压力,进而损坏设备,并有可能造成严重事故。本文用工业现场的典型故障验证了上述分析结果,并给出了消除这类典型故障的解决方案。In course of the braking of hydraulic motor, its pressure of returning line is related with the load mass, the cubage of returning line, the load velocity before motor brakes. When hydraulic motor with great inertia breaks at high - speed, the high pressure in returning line will be brought, this would demolish equipment, engender fearful accident. The typical fault in industrial scene was presented to validate above analysis result, and the solution of the fault was given.
