摘要
以先导溢流阀通过遥控口实现系统卸荷切换到高压溢流状态的时间过长 ,以及某压力机液压系统高压上升停滞等问题为例 ,在测试分析的基础上 ,找出了主要原因 ,并在不改变先导溢流阀结构的前提下 ,通过改变回路而解决了上述问题 ,经过实践证明 。
Taking the high pressure elevation stopping problem of a pressure machine hydraulic system as an example and based on analysis, research and measuring, this paper demonstrates the main reasons causing problem of over length time when the status change is made from system unloading into high pressure overflow of the pilot relief valve by remote control Given the conditions that the structure of the pilot relief valve unchanged,a solution is proposed to solve the mentioned problem by modification of the return system and the practice has been proved of realatively good effect
