Reasons and Maintenance of Excavator's Weak Walking

Welcome to this article. Let's discuss what to do when the excavator is unable to walk.

Weak traveling of the #excavator is a fault that is easy to occur in the operation of the excavator, and it is also a thorny problem. When encountering this problem, if you have relevant experience in this field, you can try to check it. If not, please do not dismantle it randomly. The traveling system of the excavator is quite complex

Serious leakage of central rotary #joint;

The rotary joint has the advantages of reducing the wear of the rotary seal ring and the dust ring in the use process, and extending the service life of the product; The resistance moment of the product in use is reduced, and the operation efficiency of the product is improved. Once the swivel joint is damaged, it will affect the operation of the entire excavator. Therefore, replace it in time to keep the excavator moving normally and working smoothly

Serious leakage of traveling #motor;

The excavator traveling motor is mainly composed of safety valve, throttle valve, one-way valve, buffer piston, balance valve, brake, etc. Any valve failure will cause excavator traveling problems

The safety valve plays a protective role in the excavator traveling system, ensuring that the pressure of the traveling system is within a specified range, so that the excavator traveling system will not have a safety accident because the pressure exceeds the maximum value

Throttling valve is a valve that can control fluid and flow by changing throttling section or throttling length and other factors. It is relatively simple in structure, so its cost and maintenance are relatively low. Therefore, when there is a problem with the throttling valve, the excavator traveling system will also suffer from adverse phenomena. Because of the low cost, it is necessary to replace one

Precautions for speed regulation with pneumatic flow control valve

There shall be no air leakage or other phenomena on the pipeline

Check whether the cylinder and other components are well lubricated

Flow control valves shall be installed around the motor
