What is the root cause of the problem that hydraulic oil replacement only treats the symptoms and not the root cause?

 In recent years, there have been continuous reports of hydraulic oil problems that cannot be resolved after replacement, whether it is caused by hydraulic oil deterioration or not. The problem still exists after replacement, and the working environment temperature of hydraulic oil is high. It is difficult to deal with problems in various harsh environments, and if the problem is not solved properly, it will not only be time-consuming and labor-intensive.

If the hydraulic oil is excessive, it will first clog some precision components. If it is treated for a long time, it may greatly affect the problem of hydraulic oil respirator failure. If not treated in a timely manner, it will directly lead to flow obstruction. Without proper protective measures, hydraulic oil pollution faults may occur. The importance of the respirator is mainly reflected in the key role of balancing the air pressure inside the hydraulic oil during the output and input process, filtering air and impurities in the hydraulic oil through the breathable device inside the oil tank.

If there are impurities in the hydraulic oil after replacement, the first step is to check the respirator. If the resistance is high, there is a high possibility of abnormal operation. Here, we need to replace it every thousand hours in daily use. This can be achieved by simply replacing the breathing filter. When encountering difficult problems, we first need to recall what problems occurred in the daily maintenance process,excavating machineryDaily maintenance costs only a few tens of yuan, and maintenance should not be taken lightly. The replacement time can only be advanced and cannot be postponed, as a large part of the failures of second-hand excavators are caused by improper maintenance.
