针对煤矿铲运机桥冷却系统在实际使用中经常存在的漏油问题,介绍了煤矿铲运机桥冷却系统的工作原理及计算,分析了漏油故障的主要原因,经过实际测量结合桥中湿式多盘制动器冷却条件的要求,初步判断制动器的进口压力太大,给出了相应的解决方法。分别对改造管路和增加节流的两种解决办法,进行冷却系统的实际测试,结果表明在增加节流的作用下能够减少压差和流量。并在现场的使用中取得到了良好的效果。
In view of the oil leakage problem existing in practical use of the coal mine scraper bridge cooling system, the working principle and calculation of the cooling system of the coal mine scraper bridge are introduced. The main reasons for the oil leakage fault are analyzed. After the actual measurement and the wet type Multi-disk brake cooling requirements, the initial judgment of the brake inlet pressure is too large, given the corresponding solution. Respectively on the transformation of the pipeline and increase the throttle of the two solutions, the cooling system for the actual test results show that the increase in the throttle can reduce the pressure and flow. And in the field of use has achieved good results.
