Standby hydraulic system of excavator and control method of standby hydraulic system
The invention provides an excavator standby hydraulic system and a control method thereof, and belongs to the technical field of engineering machinery, the excavator standby hydraulic system comprises a standby hydraulic system, the standby hydraulic system is connected with a hydraulic oil tank and a main valve, the standby hydraulic system comprises a standby pump, and an outlet of the standby pump is connected with an inlet of a diverter valve; a first outlet of the diverter valve is connected with a first inlet of the main valve, and a second outlet of the diverter valve is connected with a first inlet of the shuttle valve. By arranging the standby hydraulic system, normal action of the excavator can be guaranteed when the main hydraulic system breaks down, and the situation that the engineering progress is affected due to the fact that the excavator cannot move is avoided.
本发明提供了一种挖掘机备用液压系统及其控制方法，属于工程机械技术领域，包括备用液压系统，备用液压系统与液压油箱和主阀相连，备用液压系统包括备用泵，所述备用泵的出口连接分流阀的入口，所述分流阀的第一出口连接主阀的第一入口，所述分流阀的第二出口与梭阀的第一入口相连。本发明通过设置备用液压系统，在主液压系统出现故障时能够保证挖掘机正常动作，避免因挖掘机无法移动，影响工程进度。
