摘要
装载机是宁波港镇海港埠公司进行矿散货装卸作业的主要机械。近两年来相当部分的装载机(尤其是柳工ZL50C型)在作业中出现了以动臂升举无力为主的故障。经拆检分析,可判断为动臂油缸的内泄漏所致。更换相关密封件后,故障得以排除。但继而发现一些装载机与大多数同类装载机相比,发生该类故障的周期极短。在认真观察司机操作特点后,经分析找到产生此类故障的根源是操作不当,这为操作实践及之后的大修拆检所证实。
The loaders are the main machine of ore bulk cargo handing operation in Zhenghai port company of Ningbo port. In recent years, the lifting weakness malfunction appeared on most of the loaders especially the Liugong ZLSOC. The reason was the internal leakage of the boom cylinder which was found by overhaul analysis. The malfunction was cleaned by changing the sealing elements. But after comparing the loaders with other machines of the same kind, we found out the period of the malfunction was extremely short. Then we found the source of this kind of malfunction was misoperation by observing and analyzing the operating characteristic of the driver, and it was proved by the operation practice and the overhaul.
