1台配置了西门子CPU224型控制系统的20t全液压振动压路机,在施工过程中出现了2起与振动轮有关的故障,现分述如下。1.振动轮无振动(1)故障现象该压路机作业过程中,操作手反映振动轮无振动,观察仪表盘显示屏无转速数据显示。(2)故障排查首先,将压路机停放妥当,断开电磁阀原有线路,直接给电磁阀送电后试机,结果振动轮振动正常。由此说明电
A set equipped with Siemens CPU224 type control system 20t hydraulic vibratory roller, appeared in the course of the construction of two vibration-related failures, are as follows. 1. Vibration wheel without vibration (1) Failure phenomenon During the operation of the roller, the operating hand reflects the vibration of the vibration-free wheel, observe the dashboard display without speed data. (2) Troubleshooting First of all, the road roller parked properly, disconnect the original solenoid valve line, the power supply directly to the solenoid valve test machine, the results of the normal vibration of the vibration wheel. This shows that electricity
