东方红-60型推土机,液压系统(图1)在使用常出现以下故障,下面介绍这些故障及排除方法。一、铲刀提升缓慢原因是系统压力较低。1.油箱液面过低,油泵吸油量不足或回油滤清器堵塞。按规定添加液压油,清洗滤清器。2.进油管接头密封不好,空气进入管路,应检查,拧紧。3.分配阀关闭不严,高压油从回油阀结 Dongfanghong-60 bulldozer, hydraulic system (Figure 1) often appear the following failures, the following describes these failures and troubleshooting. One reason for the slow rise of the blade is the low system pressure. 1. The fluid level of the tank is too low, the oil pump is insufficient or the return filter is blocked. Add hydraulic oil as required and clean the filter. 2. The inlet pipe joint is not well sealed and the air enters the pipe. Check and tighten. 3.
