How to determine the source of the murmur

The operation of large corn processing machinery will emit a large sound, but it is always inevitable that there will be some abnormal noise. When all kinds of noise, is also a signal, can reflect some of its machine operation, we today to support how to determine what these noises are the case.            

　　When the normal work of large corn processing machinery, suddenly issued a high and low and heavy sound, then do not panic, quickly turn off the machine, this is the normal shutdown, do not cut its power supply, which will cause harm to the motor. If the sound is dull, it means that the motor is seriously overloaded or running out of phase. It may also be because the motor is running due to vibration and the core fixing bolt is loosened causing the core silicon steel piece to be loose and make noise.

　　If it is a large corn processing machinery sound high and low and high and low interval time is unchanged, that is bearing wear and tear so that the stator and rotor is not the same center. Just check one by one according to these three positioning can be ruled out. If the electromagnetic sound, then it is certainly the shaft core bit slant slot degree of conformity is not good, core bore is not light, rotor outer diameter processing inconsistent more than caused. When the large corn deep processing machinery wind baffle noise will be because the wind baffle small mouth edge height inconsistency, assembly often with the rotor end friction and caused by. If a non-collision noise, it may be caused by the wind blade collision fan cover.
