液压缸是挖掘机的重要组成部分,它的可靠性直接关系着整机的工作性能与工作效率。液压缸的故障主要表现为:工作无力、速度下降和静沉降大。由于液压缸的内外泄漏降低了工作装置的作业速度和工作效率,甚至无法正常工作。同时,工作中介质的流失也造成机器和环境的污染,因而
The hydraulic cylinder is an important part of the excavator, and its reliability is directly related to the work performance and work efficiency of the whole machine. The failure of the hydraulic cylinder is mainly manifested as: worklessness, speed drop, and large static settlement. Since the leakage of the inside and outside of the hydraulic cylinder reduces the working speed and work efficiency of the working device, even the normal work cannot be performed. At the same time, the loss of media at work also causes pollution of the machine and the environment.
