If the hydraulic excavator is compared to one person, then the hydraulic system is equivalent to the human blood circulation system.
The hydraulic circulation system is a very important part of the hydraulic excavator. It includes the production of precision: hydraulic main pump, hydraulic tank, multi-channel valve, oil cylinder, motor and a large number of pipes.
It is precisely because of its precision, in fact, the hydraulic system is very "fragile", needs our careful maintenance, if not maintenance or improper maintenance, can lead to a variety of failures, affecting you to bring huge losses.
Maintenance of hydraulic excavator: cleaning article
1 to keep the hydraulic oil clean.
The hydraulic oil must be placed in a clean position. The oil change is to use the clean filter funnel with fine screen to pour oil from the container.
If the oil tank contains impurities in the hydraulic oil, it will block the valve, abrade the pump and block the oil port, causing the machine failure.
2 keep the system clean.
Replace the filter of hydraulic oil and hydraulic oil regularly. Because there are many additives in hydraulic oil, the original effect of these additives is to prevent the deterioration of hydraulic oil, but it will expire after 5000 hours, and new hydraulic oil should be replaced at this time. In addition to changing the oil, the water and sediment in the tank should be removed regularly. If there is sediment in the tank and not cleaned, replacing hydraulic oil is useless.
3 to maintain the cleanliness of the working area.
When filling the tank, ensure that the area around the filter box cover is clean. Only a clean funnel or container can be used. Do not bring the dirty things into the system. When maintaining the hydraulic system, only the clean plastic plug can be used for the end of the sealing pipeline. The workbench must be absolutely clean when maintaining hydraulic components. Checking the condition of using tools must also be clean.
