压力过低和压力过高是液压系统的典型故障。液压泵、控制阀和执行元件如有故障,都会使液压系统的压力出现异常。1.压力过低(1)根本无压力这说明系统中动力元件未提供压力油,应检查液压泵与油箱之间的所有零部件。首先检查油箱中液压油是否充
Underpressure and overpressure are typical failures of the hydraulic system. Hydraulic pump, control valve and actuator failure, will make the hydraulic system pressure abnormalities. 1. Low pressure (1) No pressure at all This means that no pressure oil is supplied by the power components in the system. Check all the components between the pump and the oil tank. First check the fuel tank is filled with hydraulic oil
