YZC10型振动压路机的行走系统采用了机、电、液一体化技术,因此一旦行走系统出现故障,应从机械、电气、液压三个方面去查找故障原因。该机行走系统的电路见图1、液压系统原理见图2,因机、电、液方面原因而造成该机行走无力或无动作的故障事例如下。 1.机械原因 现象:机器突然出现无行走动作,但其他动作正常。 检查:打开与制动器连接的液压油管(图2中A点或B点)时,有一定的 YZC10 vibratory roller walking system uses a machine, electricity, liquid integration technology, so once the traveling system fails, should be from the mechanical, electrical, hydraulic three aspects to find the cause of the malfunction. The machine running system circuit shown in Figure 1, the hydraulic system principle shown in Figure 2, due to machine, electricity, liquid aspects of the cause of the machine to walk weakness or no action failure cases are as follows. 1. Mechanical reasons: the phenomenon of sudden no-walk machine, but the other movements are normal. Check: When opening the hydraulic tubing connected to the brake (point A or point B in Figure 2), there is a certain
