Corn processing machinery Several forms of noise expression and elimination 。 Corn processing machinery is mainly used for corn processing and production. In use, due to the motor drive, the corn kernels are ground into powder. In this process, some noises may appear, some of which are transmitted by the machine normally. The appearance of some noises means that there are some problems in the equipment. The staff should find out the source of the noise and solve it in time.
Corn processing machinery
Generally speaking, there are several detection methods for noise in the production of corn processing machinery
1. Electromagnetic sound. It is divided into high frequency and low frequency. It is caused by the poor conformity of the shaft core position inclined groove, the inner bore of the iron core and the inconsistent processing of the rotor outer diameter.
This is often caused by the high and low friction of the wind shield plate, which is caused by the high and low friction of the wind shield plate.
3. When the motor is running, there will be high and low and heavy sound. The reasons are as follows:
(1) the air gap between the stator and the rotor is not uniform. At this time, the sound varies from high to low, and the interval between high and low pitch is unchanged. This is caused by bearing wear which makes the stator and rotor not concentric.
The iron core is loose. During the operation of the motor, the fixed bolts of the iron core are loosened due to the vibration, resulting in the looseness of the silicon steel sheet of the iron core, and the noise is generated.
The three-phase current is unbalanced. This is due to the wrong grounding, short circuit or poor contact of the three-phase winding. If the sound is very dull, it indicates that the motor is seriously overloaded or runs without phase.
Several noise forms and elimination methods of corn processing machinery.
