Sharing of tips for daily maintenance of excavators

If the hydraulic excavator is compared to a person, then the hydraulic system is equivalent to the human blood circulation system.

The hydraulic circulation system is an extremely important part of the hydraulic excavator. It includes precision-made: hydraulic main pump, hydraulic oil tank, multi-way valve, oil cylinder, motor and a large number of pipelines.

Because of its precision production, the hydraulic system is actually very "fragile" and requires our careful maintenance; if it is not maintained or improperly maintained, various failures will occur, affecting you and causing huge losses.

1 Keep the hydraulic oil clean.

The hydraulic oil must be placed in a clean place. It is necessary to pour the oil from the container into the oil tank with a clean funnel equipped with a fine grid filter. If the hydraulic oil contains impurities, it will jam the valve, scratch the pump, and block it. Oil port, causing machine failure.

2 Keep the system clean.

Replace hydraulic oil and hydraulic oil filters regularly. Because there are many additives in hydraulic oil, the original function of these additives is to prevent the hydraulic oil from deteriorating, but it will expire after 5000 hours. At this time, the hydraulic oil should be replaced with a new one. In addition to changing the oil, the water and sediment in the fuel tank should also be regularly removed. If there is sediment in the fuel tank without cleaning, replacing the hydraulic oil will have no effect.

3 Keep the work area clean.

When filling the fuel tank, make sure that the area around the filter box cover is clean. Only use clean funnels or containers. Do not bring dirt into the system. When maintaining the hydraulic system, only clean plastic plugs can be used to seal the ends of the pipeline. When maintaining hydraulic components, the workbench must be absolutely clean. Check the condition of the tools used, they should also be clean.
