机械设备如果出现液压系统泄漏故障,不仅会降低系统压力影响生产,还会污染环境。但量几乎所有的液压机械都会出现泄漏的故障,特别是吊车液压系统,这是由于吊车在作业过程中,液压元件与管路在流动时会产生压力差,液压缸活塞与密封件之间有间隙;并且吊车的作业环境也比较恶劣,都会影响到液压系统的密封性能。针对起重吊车液压系统的泄漏故障进行分析。 Mechanical equipment in case of hydraulic system leakage failure, not only will reduce the system pressure affect the production, but also pollute the environment. But the amount of almost all the hydraulic machinery leak problems, especially the crane hydraulic system, which is due to the crane in the operation process, the hydraulic components and piping flow will produce a pressure difference between the hydraulic cylinder piston and seal Gap; and cranes operating environment is relatively poor, will affect the sealing performance of the hydraulic system. Analysis of the leakage of hydraulic system of lifting crane.
