Excavator hydraulic system maintenance method

mportance of hydraulic system maintenance of excavators:

Excavators may encounter some minor problems in daily use, big faults, many excavator masters often consult the excavator repair shop after encountering the fault problem, and spend a lot of fault repair costs, in fact, if the excavator master is in daily life The excavator can do a good job of daily maintenance of the excavator to avoid these failures to a large extent.

1 First of all, to do the hydraulic system maintenance of the excavator, you must choose the right excavator hydraulic oil.

Excavator hydraulic oil is especially important for excavators. Hydraulic oil plays a role in lubrication, cooling and sealing in excavators. Therefore, choosing the right excavator hydraulic oil is a point that excavator masters must know.

When selecting excavator hydraulic oil, it must be selected according to the requirements of the manual. If you want to use substitute oil under special circumstances, you must also choose the same performance as the original hydraulic oil. Do the above two points to effectively prevent the hydraulic system of the excavator from malfunctioning. happened.

In addition, the discolored hydraulic oil can not be used.

2 Excavator hydraulic system maintenance method "When using oil, prevent impurities from entering the hydraulic system"

If impurities enter the hydraulic fluid during the oil change process of the excavator, it may cause strain, card issuance or oil passage blockage of the internal parts of the hydraulic system.

Therefore, in the excavator replacement process involved: the staff's overalls, refueling tools, oil change environment, etc. must be strictly in accordance with the requirements of the instructions.

3 Excavator hydraulic system maintenance method "cleaning of excavator hydraulic system"

The same hydraulic oil should be used when cleaning the hydraulic system of the excavator, and the temperature of the hydraulic oil should be 45 to 80 degrees. It should be cleaned more than three times. After cleaning, the hydraulic oil is released, and the filter is cleaned. Filter element, then add new oil.

Pay attention to the process of refueling:

To prevent air from entering the hydraulic system, if air enters the hydraulic system, it may cause the pump to be emptied, which will cause cavitation and reduce the efficiency of the excavator. Therefore, be sure to pay attention when changing oil.

Also prevent water from entering the hydraulic system. Water entering can cause corrosion of hydraulic system components, emulsification of oil, and accelerate mechanical wear. Therefore, in order to maintain the hydraulic system of the excavator, it must be noted in the hydraulic oil to be replaced. Do not have moisture.

4 Excavator hydraulic system maintenance method "Use the excavator according to the regulations"

Failure to use the operating excavator in accordance with the instructions may also cause the excavator to malfunction.

5 Excavator hydraulic system maintenance method "do the excavator timing maintenance work"

Excavator should check the filter screen when it is used for 250 hours, check the filter element for 500 hours, replace the filter element for 1000 hours, clean the hydraulic oil tank, change the hydraulic oil. Check and adjust after 7000 hours and 10000 hours.
