摘　　要：工程机械常用的液压平衡回路，存在着悬垂负荷再提升下滑和下降冲击、振动的问题。本文从系统结构分析出发，针对以上两问题作了原理上的分析，采用蓄能器记忆压力和补充油液，并用压力比较定时元件来控制提升与制动释放同步动作，为克服提升瞬间下滑，提出了简单、有效的解决方案。Several problems exist in the commonly used hydraulic balancing circuits, such as drift in re－lifting of suspended load and shock and Vibration in lowering. In view of the above two problems and starting from an analysis of the system structure, a simple but effective solution to overcome the momentary drifting in the lifting is presented by adopting the memory pressure of accumulator and charging oil, together with pressure－comparing timing device to control synchronous actuation of lifting and breaking relief.
