1台柳工产ZL50C型全液压装载机在装卸物料时,突然出现转向时有时无现象。经试机检查,发现挂挡微动或行走时可以左、右转向,但不挂挡原地操作转向盘转向时,2个转向轮却只能左、右转动15。左右。1.查找故障点该机转向液压系统原理如图1所示。该机采用流量放大转向液压系统,与工作装置液压系统是相互独立的。转向液压系统主要由转向泵、转向器、
1 Taiwan Liu ZL50C full hydraulic loader in the loading and unloading of materials, the sudden emergence of steering sometimes no phenomenon. The test machine inspection and found that when the hang-up fretting or walking can be left and right steering, but do not hang up in place to operate the steering wheel steering, the two steering wheels can only turn left and right 15. about. 1. Find the point of failure The machine steering hydraulic system shown in Figure 1. The machine uses flow amplification steering hydraulic system, hydraulic system and the working device are independent of each other. Steering hydraulic system mainly by the steering pump, steering gear,
