摘要
通过对采煤机液压系统故障的分析,指出液压油是保证采煤机工作效能的一个重要前提,并对液压油选用的主要技术指标和保持油液使用的合理性进行了阐述。
Through the analysis on the failures of the coal cutter＇s hydraulic system, this paper points out that the hydraulic oil is an important precondition for guaranteeing the working performance of the coal cutter, and expounds the main technical indexes for selecting the hydraulic oil and how to make rational use of hydraulic oil.
