Troubleshooting of hydraulic pump components
Hydraulic pump plays an important role in the equipment, each component is also very important, hydraulic pump components failure is divided into a variety of, some need to be replaced, and some need to repair, depending on the situation.
Two. Classification of faults
All equipment faults or component faults can be divided into random faults and regular faults.
Random failure is unpredictable, the interval cannot be estimated, a random failure of the development process can be determined, with the state monitoring method for example, the problem of hydraulic pump and motor spindle fracture; random fault free development process cannot be determined according to the observation, people can only record and fault data analysis, through improved design of reducing fault.
Regular faults can be predicted, so the interval can be estimated. The regular faults in the development process can be measured by the "state monitoring method", for example, the clogging of the filter; the regular failure of the non development process can be scheduled for parts replacement or maintenance, for example, the variable swing support of the hydraulic pump motor is damaged.
Generally, the fault can be classified from different angles such as engineering complexity, economy, safety, the speed of fault occurrence and the cause of the fault, and so on:
1, intermittent fault
The failure that occurs in a very short period of time, causes the equipment to lose some function locally, and then returns to its normal state immediately after the accident occurs. For example, the roller vibration solenoid valve plug contact is bad, resulting in sometimes energized, sometimes power off, making the roller vibration sometimes work, sometimes not work.
2, permanent fault
Some failures will make the equipment lose some function, and can not automatically restore to normal state, until the failure of the parts repair or replacement, the function of the device to restore, such failures, we call it permanent fault. For example, the roller vibration pump damage, resulting in vibration does not work, the hydraulic pump must be repaired, the vibration function can be restored.
