Before the failure of weihe tractor, there will be some special phenomena, which is the precursor of the failure.These precursors usually have visible, audible, audible, touchable, or measurable properties, which can be roughly summarized as follows:

1. Abnormal appearance.If the exhaust pipe emit black smoke, white smoke or blue smoke, there are water leakage, oil leakage, electricity leakage and leakage of the phenomenon, the light is not bright, parts or parts of the confusion, meter reading beyond the normal value.

2. Abnormal function.The technical state and performance of weihe tractor are abnormal, such as the engine is difficult to start, braking failure, the main clutch slipping, the generator does not generate electricity and the traction is too small.

3. Abnormal consumption.Such as diesel oil, oil and cooling water consumption is too high.

4. Abnormal temperature.Such as clutch overheating, bearing overheating and generator overheating.

5. Abnormal odor.Exhaust belt combustion does not completely give out the smell of oil or friction pieces burnt smell

6, abnormal sound, tractor working engine there are abnormal knocking sound, sound and noise.

The above phenomenon is the tractor fault 'early warning', operators need to according to these 'early warning' specific analysis, timely diagnosis, as soon as possible to find out the cause, will be trouble trouble elimination.
