YZ10B振动压路机常见的故障是振动频率异常。我们在实践中总结出该故障产生的原因及排除方法如下：1．液压案效率低，排量达不到要求正常工作时一般液压泵工作压力为16MPa～20MPa，排量应在80cm’／r以上。若达不到以上值，振动频率就会降低。液压泵效率低的原因有：泵的密封环
YZ10B Vibratory Roller common fault vibration frequency is abnormal. We summarize in practice the reasons for the failure and troubleshooting are as follows: 1. Hydraulic case of low efficiency, displacement of less than the normal working hours of the general hydraulic pump working pressure of 16MPa ~ 20MPa, displacement should be 80cm ’/ r or more. If the above value is not reached, the vibration frequency will be reduced. The reasons for low efficiency hydraulic pump: pump seal ring
