Failure

The occurrence of a malfunction or abnormality of the crawler mucking loader is caused by many factors such as manufacturing, operation, use environment, and maintenance. Some faults are mutually influential. For example, insufficient coolant in the diesel engine will not only increase the temperature of the diesel engine and the temperature of the oil, but also affect the temperature of the double-change oil.

The crawler mucking loader is mainly used for mine rock roadway and semi-coal rock roadway excavation. It can also be used for loading work in diversion tunnels, railway tunnel construction and defense cave construction, greatly improving the tunneling speed, and can be applied to large sections with a slope of +20°. ~-32° laneway. First of all, it should be stopped, and then analyzed according to the characteristics of the fault, and the fault nature should be judged initially. It is not advisable to force the sick operation, otherwise the fault will continue to expand as the working time continues. The inspection and judgment of faults should be combined with theoretical knowledge and practical experience as much as possible, using a comprehensive approach of seeing, touching, listening, smelling, and testing.

Look: Observe the changes in the readings of each meter, the condition of each connected component, the leakage of each combined sealing surface, the abnormality of each oil and water, and the smoke color of diesel exhaust.

Touch: Check the surface temperature, connection condition and vibration of each component by hand.

Listening: Determine the abnormal sounding part by judging the sound emitted by the working element and its changes according to the hearing.

Sniffing: I feel the smell of each part and each oil by smell.

Test: When conditions permit, test can be carried out according to requirements, and the cause of the fault is analyzed according to the test result.

Through the above methods, the crawler mucking loader has a preliminary judgment. After the preparation work before disassembly, it is dismantled in strict accordance with the sequence. During the disassembly process, the use of the components should be carefully and carefully observed and discharged. In order to further confirm the cause of the fault, the original signs of the fault zone should be protected and recorded. The fault can be repaired after the cause of the fault is identified.
