The contents of MINI excavator regular maintenance and maintenance

[BONOVO]

MINI excavators sometimes jam up during construction, because the instantaneous speed is too large, the gate valve will be blocked, and the internal structure will leak, which will lead to common problems, reduce the efficiency and reduce the service life. When repairing the hydraulic transmission system of excavators, some abnormal signs often occur. Therefore, daily maintenance is very important, and we will talk about it briefly.

1, before starting the hydraulic transmission system, please carefully explore whether the limit part and tee are loose and whether the pipeline is deformed or damaged.

2, before the first hydraulic cylinder, try to leak oil first to prevent the hydraulic cylinder from being destroyed by the actual pneumatic operation.

3, when the hydraulic cylinder starts, it can continue to work (novel is in cold areas) to test whether it is flexible. Before you start the actual operation, make sure that everything is normal and there is no noise.

4, when the working pressure of the hydraulic transmission system multiway valve manufactured by the machine is higher than or below the limit value.

5, after the hydraulic transmission system is in stable operation, not only pay attention to the temperature of water, working pressure and noise, but also pay attention to the operation of hydraulic cylinder, oil motor, hydraulic reversing valve and gate valve.
