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。
Take the pilot relief valve to realize the long time that the unloading of the system is switched to the high-pressure overflow state through the remote control port and the stagnation of high pressure of the hydraulic system of a press as an example. Based on the test analysis, the main reason is found out. Without changing the structure of the pilot relief valve on the premise, by changing the circuit to solve the above problems.
