全液压振动压路机一般都设有测压日，并配置了液压油压力测试仪表。因此，如何利用测压的方法来快速诊断故障值得重视。压路机行走液压系统的常见故障有：整机不能行走。驱动功率太低及行走不平稳跳动等。下面以YZ18GD全液压振动压路机为例（见附图），介绍通过测压诊断上述故 Full hydraulic vibratory rollers are generally equipped with pressure measuring day, and the configuration of the hydraulic oil pressure test instrument. Therefore, how to use the manometric method to diagnose faults quickly deserves attention. Roller hydraulic system to run the common faults are: the whole can not walk. Drive power is too low and walking is not smooth beating and so on. The following to YZ18GD full hydraulic vibratory roller as an example (see photo), introduced by pressure measurement to diagnose the above
