Inspection and maintenance of hydraulic pump

Good equipment must have a good repair and maintenance, so that the equipment will be used for a longer time, higher safety performance. About the hydraulic pump, this is one of the important components in the equipment, more need our daily life in the establishment of reasonable detection and maintenance.

Establishing preventive maintenance. The basic means of maintenance include inspection, maintenance, replacement and commissioning. Pump preventive maintenance is to pump on line regularly, pump hard life every 1500 hours for a flush, this method is to improve the pump life is one of the most effective methods.

A common maintenance method is to repair at a predetermined time. For a typical example, the bearing life of the pump is ten thousand hours, but this soft life is only a reference, which can extend the time, but it must be estimated that such extension will increase the risk of damage to the pump.

The hydraulic system of metallurgical industry is very complex, especially the impact of pollution, accurate assessment needs a wealth of experience, but we can according to the hard life of the pump, (hard life - equipment service time) computer analyzer on the operation of the bearing three pairs of friction and rolling bearing were analyzed by timely, correct according to the working state of judgment and accurate analysis of the friction pairs and bearing in operation, according to the damage trend to estimate the residual life of the pump and bearing, and timely replacement program, in order to avoid the accident caused economic losses.

The probability of failure of the hydraulic pump and the pump increases with age, from the pump service began to establish the corresponding record, interval time, hard life and each record pump has reached the flushing bearing replacement, maintenance and testing results, quality acceptance of a set of maintenance records.

The establishment of professional equipment supervision personnel, the exercise of equipment operation, maintenance, maintenance of the whole process of supervision function, make the equipment maintenance management scientific, digital, realize the equipment maintenance "zero fault"".

Pump is the most valuable component in the whole hydraulic system component. It is difficult to predict what kind of maintenance the pump needs when the pump is not on-line monitored and tested. If you do not record and do not analyze the monitoring pump data, it is almost impossible to determine whether the online pump can operate according to the specified service period.

In China's Xiaolangdi Dam project and the construction of the Three Gorges Project foreign contractors on its use of hydraulic pumps, hydraulic motors adhere to 1500 ~ 2000h hours for a wash, the hard life of 8000h, that is, the pump, motor replacement bearings and adjustment. This is our use of imported hydraulic equipment units can learn from.

If a pump appears detectable deterioration signs, there is enough time to observe the deterioration degree before the failure occurs, then it is reasonable to conduct online regular inspection of the pump. To strengthen the maintenance and protection, can improve the service life of the pump (utilization). Foreign equipment management has a famous saying: "maintenance is for the use of equipment and fault management."".

So the establishment of state based detection of periodic inspection, maintenance system, daily timing detection, make a record of the on-line use of the pump to draw, pressure and temperature, noise level, the current value and the curve table make trend analysis of state recognition and status of pump maintenance maintenance policy.
