How to carry out loader transmission repair and maintenance

[BONOVO]

The hydraulic transmission oil is the energy carrier of the normal work of the transmission, in the hydraulic transmission system, the pressure, temperature and flow of the working liquid determine whether the transmission can work normally, so in the daily maintenance of the transmission, special attention should be paid to the inspection and replacement of the hydraulic transmission oil.

1. Fix the oil change interval
Changing the oil at the right time interval is the key to maximizing the working life of the components in the gearbox. Only by ensuring a reasonable oil change interval can the lubrication and protection characteristics of the lubricating oil be brought into play.

Under normal circumstances, it should be based on the maintenance cycle recommended by the manufacturer of the whole machine, but this can only be relative, and it must be combined with the analysis results of the oil sample extraction to know the actual work.

For example, the maintenance manual requires that the oil change interval of the gearbox is 1000h, we sample the oil sample every 500h or 250h according to the operation of the loaderto determine when to change the oil, but the oil should be replaced immediately when it is used to 1000h. In addition to the regular replacement of new oil, in the usual inspection, if the oil is found to be deteriorated or mixed with impurities, it should also be cleaned and checked, and replaced with new oil.

2, the use of correct drainage, oil change method
When discharging oil, the oil temperature should reach 40 ~ 50 ° C, and the oil flow should be discharged in the case of agitation, and the dirty oil should be drained as thoroughly as possible; When refueling, a refueling machine with a filter device should be used to add oil.
3. Use the correct transmission system oil, and the lubricating oil used in the gearbox must meet the specifications.
4. Replace the filter in time by referring to the filter replacement cycle provided in the maintenance manual.
5, all kinds of lubricating oil must be pure, and after a period of precipitation, in line with the specified quality requirements.

Therefore, it is very necessary to strengthen the fault prevention and daily maintenance of the gearbox in the daily use process, which can not only reduce the inefficiency and delay the working time caused by the shutdown and maintenance, but also prevent and avoid the occurrence of greater subsequent failures, reduce maintenance costs, and improve the safety of the machine.
