采煤机摇臂漏油问题分析

Analysis of Oil Leakage in Rocker arm of Shearer

采用MDY-150型号的单滚筒采煤机进行采煤工作时,刚开始确实有好的采煤效果.但是在采煤工作进行5个月之后,摇臂两轴和套子之间都存在不同程度的漏油情况.本文结合实际案例对采煤机摇臂使用过程中的漏油问题进行全面的研究,通过分析采煤机摇臂漏油产生的原因主要有浮动油封存在问题、密封的结构出现变化、密封材料的影响、油封会在使用的过程中发生断裂的现象等四个方面,针对产生的原因制定了通过选择合适的材料来确定间隙、有效更换支撑的轴承、选择带有凹槽的浮动油封、安装浮动的油封盘等四个解决采煤机摇臂漏油问题的主要策略,在经过2年的时间之后,已经基本上解决了油封漏油的问题,不仅有效地增加了采煤机工作的时间,也延长了采煤机的使用寿命,非常值得在企业内部推广.也希望能够给大家更多的参考性意见.

When mdy-150 single drum shearer is used for coal mining,it has a good effect at the beginning.However after five months of coal mining work,there are different degrees of oil leakage between the shaft and sleeve of the rocker arm.Combining with the actual case of oil spill problem in the process of coal winning machine rocker arm used to conduct a comprehensive study,through the analysis of the causes of coal winning machine rocker oil main problems have floating oil seal,seal structure change,the influence of the seal material and seal in the process of using four aspects,such as the phenomenon of fracture for reasons made by selecting suitable materials to determine the gap and effective support of replacement of bearings,and the choice of ovedfloating oil seal,installation of floating oil seal plate and so on four main strategy to solve the problem of coal winning machine radial leakage,after 2 years,Has basically solved the problem of oil seal leakage,not only effectively increased the working time of the shearer,but also extended the service life of the shearer,is very worthy of promotion in the enterprise.Also hoped can give everybody more reference opinion.
