压力转换滞后现象是液压系统经常可能出现的一种控制问题。它体现在工作机构上的压力变化往往跟不上实际控制的需要,难以及时建立新的压力系统。出现压力转换滞后现象,对于液压设备的正常工作有严重危害。造成压力转换滞后主要有4个原因。1．溢流阀阀芯不能正常动作溢流阀是用来调节系统压力的控制
Pressure conversion hysteresis is often a hydraulic system control problems may arise. It manifests itself in the pressure of working institutions often can not keep up with the actual control needs, it is difficult to establish a new pressure system in a timely manner. Appear the pressure change hysteresis phenomenon, have serious harm to the normal work of the hydraulic equipment. There are four main reasons for the lag in pressure conversion. 1. Overflow valve spool can not be normal operation Relief valve is used to adjust the system pressure control
