部队为了适应新时期发展的需要,购买了大量的新型工程机械,在使用过程中经常遇到工程机械液压系统失压而不能正常工作。结合新型工程机械的实际情况,分析新型工机械液压系统失压的故障原因,提出排除这种故障的方法。 In order to meet the needs of the development of the new era, the army purchased a large number of new construction machinery. During the course of its use, the troops often encountered pressure loss in the hydraulic system of the construction machinery and could not work normally. Combined with the actual situation of new construction machinery, the failure mechanism of new-type mechanical hydraulic system is analyzed, and the way to eliminate this kind of fault is put forward.
