The invention discloses a decompression monitoring assembly, a hydraulic control system and a hydraulic lifting device. The decompression monitoring assembly comprises a pressure relay; an oil measuring port of the pressure relay is connected to a pressure measuring point so as to monitor whether the pressure measuring point loses pressure or not, and when the pressure measuring point loses pressure, a pressure loss signal is automatically sent out; the set pressure threshold value of the pressure relay is not lower than the action pressure value of the pressure relay in the simulated decompression state. According to the technical scheme, the problem that the timeliness and reliability of monitoring results of an existing voltage loss abnormity monitoring technology are insufficient can be solved.
本发明的失压监测组件、液压控制系统及液压升降装置,包括压力继电器;所述压力继电器测油口连接于测压点以监测所述测压点是否失压,且在所述测压点失压时自动发出失压信号;所述压力继电器的设定压力阈值不低于所述压力继电器在模拟失压状态下的动作压力值。本发明技术方案,可解决现有失压异常监测技术监测结果及时性可靠性不足的问题。
