Core tip: engineering machinery hydraulic oil replacement minor sense: engineering machinery on hydraulic components are many, need sufficient hydraulic oil. When the hydraulic oil needs to be replaced by too long time, someone mistakenly thinks that only the oil in the hydraulic mailbox will be released and the new hydraulic oil is filled.
There are many hydraulic components on construction machinery, and sufficient hydraulic oil is needed. When the hydraulic oil needs to be replaced by too long time, someone mistakenly thinks that only the oil in the hydraulic mailbox will be released and the new hydraulic oil is filled. But at this time, there are still many old hydraulic oil in the hydraulic tubing and hydraulic control valve. When the equipment is used, the new and old oil mixture will accelerate the speed of new oil deterioration.
The correct oil transfer steps should first release the hydraulic oil in the hydraulic mailbox, clean the oil tank and add the new hydraulic oil, then remove the loop general pipe, start the engine after the downturn, so that the operating hands of the oil pump can be operated separately, and the oil will be discharged from the old oil in the loop until the new oil is out of the main pipe. Finally, connect the return manifold with the fuel tank and replenish the new hydraulic fluid to the specified position.
Of course, this oil exchange also has its defects, say with the pilot loader, so oil change, first idle speed, the pilot oil pressure is 35 kilograms, just start the machine, the pilot oil (the new oil for new) to the oil pipe, is to prepare 3 barrels of hydraulic oil is not necessarily enough, in addition, the oil pipe is not only one, and the oil pipe is not only one, the oil tubing is also only one, the oil tubing is also not only one, the oil pipe is also not only one, the oil pipe is also not only one, the oil tubing is also not only one, the oil pipe is also not only one, the return tubing is also not only one, the oil pipe is also not only one, the return tubing is also not only one, the oil pipe is also not only one, the return tubing is also not only one, the oil pipe is also not only one, the oil pipe is also not only one, the oil tubing is also not only one, the oil pipe is also not only one of the oil tubing, It needs to be removed one by one, so it is very difficult to do it one by one.
As the saying goes, "sharpen your knife without cutting the chopsticks", don't be afraid of trouble! Think about it, although the oil change is slow, it also needs to be determined by the specific model and the situation, but it is enough to do it for a maximum of half a day. How much money can this day make? If a component is damaged due to dirty oil, how much money will be eaten only for spare parts besides maintenance time and cost? This is absolutely not alarmist!
