What to do if there is noise in the production of corn processing machinery

corn processing machinery is mainly equipment for processing and producing corn. In use, due to the rotation of the motor, the corn kernels are pulverized into powder. During this process, some noise may occur, and the appearance of these noises means that the production of equipment has appeared. For some problems, the staff should find out where the noise is coming out in time, solve these problems, let the work go smoothly, and avoid causing bigger problems.

　　 Generally speaking, there are several detection methods for noise in the production of corn processing machinery:

1. The windshield of the corn processing machinery makes an abnormal noise, which has a lot to do with the compliance of the windshield. It is because the welding point is rough during the processing of the corn processing machinery, and the edge of the windshield is inconsistent with the rotor. Caused by friction at the end.

　　2, electromagnetic sound. Divided into two kinds of high frequency and low frequency. Kenneng is caused by poor conformity of the skew degree of the shaft iron core position, poor iron core bore, and inconsistent rotor outer diameter machining. Usually, the replacement of the rotor is used to eliminate and solve this type of problem.

　　3. There will be a high, low and heavy sound when the motor is running. Probably the reasons are as follows:

　　1) The air gap between the stator and the rotor is not uniform. At this time, the sound fluctuates and the interval between high and low frequencies does not change. This is caused by the bearing wear that makes the stator and rotor not concentric.

　　 2), the three-phase current is unbalanced. This is because the three-phase windings are grounded incorrectly, short-circuited, or poorly contacted. If the sound is dull, it means that the motor is seriously overloaded or running without phase.

　　3) The iron core is loose. When the motor is running, the iron core fixing bolts are loosened due to vibration, which causes the iron core silicon steel sheet to loosen, causing noise.
