我公司在试制XE215CLL履带式液压挖掘机时,该车在启动后操作行走动作出现故障,整车的左、右行走方向均与实际操作方向相反,文章对该挖掘机行走故障的排查诊断进行了分析描述。1压力测量因为右行走和左行走故障现象一样,我们现场选定右行走的先导管路作为故障排查点。对主阀右行走阀芯两端的先导油口pAtr、pBtr同时进行压力测量,具体测量结果如下。
When the company trial XE215CLL crawler hydraulic excavator, the car after the start of the operation of the operation of a fault, the vehicle left and right directions are the actual operation of the opposite direction, the article on the excavator troubleshooting troubleshooting carried out Analyze the description. 1 Pressure Measurement Because right-hand travel and left-hand travel are the same, we selected the right-walking pilot line as the troubleshooting point in the field. The main valve right-hand spool at both ends of the pilot port pAtr, pBtr pressure measurement at the same time, the specific measurement results are as follows.
