Severe wear of the excavator hydraulic pump has a fatal impact on the excavator, so such problems must be solved in time. When repairing the excavator hydraulic pump, look for the cause of the fault from the following three points:

The filter element plays the role of filtering impurities in the oil or gas lines to prevent them from intruding into the system and causing malfunctions; various filter elements should be replaced regularly in accordance with the requirements of the (Operation and Maintenance Manual); when replacing the filter element, check whether there is metal attached to the old If metal particles are found on the filter element, diagnose it promptly and take improvement measures; use a pure filter element that meets the machine's regulations. The filtering ability of fake and inferior filter elements is poor, and the surface and material quality of the filter layer do not meet the requirements, which will seriously affect the normal use of the machine.

Daily inspection work is an important link to ensure that the hydraulic excavator can maintain efficient operation for a long time, especially for the self-employed, doing a good job in the daily inspection work can effectively reduce the maintenance cost.

First around the mechanical turn two laps check appearance and mechanical chassis, and rotary support whether there is oil outflow, then check the deceleration brake device and the crawler bolt fasteners, the tighten the tightening, the timely replacement, if it is a wheeled excavator will need to check whether the tire is strange, and the stability of the pressure.

Check whether the excavator bucket teeth have large wear, it is understood that the wear of the bucket teeth will greatly increase the resistance in the construction process, which will seriously affect the work efficiency and increase the wear of equipment parts.

Check whether the bucket rod and the oil cylinder have cracks or oil leakage phenomenon. Check the battery electrolyte to avoid being below the low level line.

Air filter element is an important part to prevent a large amount of dusty air from entering the excavator, and should be checked and cleaned frequently.

Check often the fuel oil, lubricating oil, hydraulic oil, coolant, etc., whether you need to add, and it is best to choose the oil according to the requirements of the instructions, and keep clean.

The difference between shovel machine, loader, bulldozer and excavator

Do you know what are the common faults of excavators?

How should we prevent and protect our machinery before failure occurs?

How do we deal with these emergency failures if they occur?

With the continuous advancement of the modernization construction, the excavator has become an indispensable and important equipment in the engineering construction. For the operation of excavator, professional training and a solid knowledge foundation are needed.
