Many operators will encounter the situation that the automatic feeding mixer cannot walk during work. If you can't walk normally, it will certainly affect your normal work. However, don't panic, find the reason and eliminate the fault. Let's make a simple analysis.
Check the transmission oil limit valve and the transmission pressure gauge. If the transmission and variable distance oil are found to be missing, add new oil, but not too much, otherwise the transmission will be heated. Usually, oil added to the limit valve can flow out of the position valve.
Check whether the boom can rise and fall and whether there is steering. If the boom can rise and fall, it can also complete the steering action, but the machine itself cannot realize the walking process. This is mainly due to the lack of oil and water caused by the damage of variable speed pump.
The boom cannot take off and land, cannot realize steering action, and cannot walk. This situation is mostly caused by the steel plate connecting rod driven by the mixing bucket being cut off by bolts and the elastic plate being broken. Lift the diesel engine and gearbox together, remove the connecting parts of the torque converter diesel engine, check the damaged parts, and replace and repair parts.


In addition, prevent the fuel from leaking into the oil pan, because the oil pan will dilute the oil, greatly reduce the viscosity of the oil and prematurely lose the lubricating effect. Good atomization and reasonable throttle control ensure the complete combustion of fuel.
Avoid the engine working in high temperature environment. The normal working temperature of the engine is generally 80 ° C to 95 ° C. If the temperature is too high, the oil will become thin and accelerate the deterioration of the oil. Once the temperature is found to be too high, stop the machine immediately for inspection and continue to work after troubleshooting.
As the long-term use of the automatic feeding mixer will cause the blockage of the mechanical filter element, serious blockage will force the safety valve to open, and the unfiltered oil will directly enter the moving pair surface after the safety valve and be opened, which will aggravate the machine. The wear of parts will also cause the accumulation of impurities in the oil pan and accelerate the failure of oil products. Therefore, it is very important to clean the filter and replace the filter element regularly.
Therefore, no matter any equipment fails, we must take it seriously, find the root cause of the problem, and then find the corresponding solution. For more information, please visit Com.
