推土机在长期使用后,会发生推土铲自动下沉故障。将推土机推土铲提起后,将发动机熄火,此时若见推土铲自动下沉,且超出8mm/min的自然沉降量标准,就说明推土机液压元件内泄漏严重。本文主要探讨液压元件内泄漏量的测量方法,以便准确查找泄漏部位。1.内泄漏源分析某型推土机工作装置液压系统主要由先导泵1、工作泵2、过滤器3、油箱4、溢流阀5、安全阀6、补油溢流阀
Bulldozers in the long-term use, the bulldozer will occur automatically sink fault. After the bulldozer blade lift, the engine flameout, this time if you see the blade automatically sink, and beyond the natural settlement of 8mm / min standard, it means bulldozer hydraulic components within the serious leakage. This article mainly discusses the measuring method of the leakage of hydraulic components, in order to accurately find the leak site. 1. Internal Leakage Source Analysis A bulldozer working unit hydraulic system mainly consists of pilot pump 1, working pump 2, filter 3, fuel tank 4, relief valve 5, safety valve 6, charge relief valve
