In many factories and enterprises, miners will be in explosionMotorIt is used in medium, but there is some decibels of mechanical noise in operation, but how is the noise generated?

For most of our industrial technology and China’s mining industry, explosion-proof motors provide power sources for the production and operation management of enterprises and the security of social production information. However, one thing that cannot be ignored is that motors are also one of the main noise sources affecting the culture environment One.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Explosion-proof motorsA type of motor that can be used in flammable and explosive plants, and it does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.With the research on the development of our country's economy and the improvement of the actual quality of life of the Chinese people, industrial and mining enterprises have also received more and more attention to improve the production, education, work and learning environment of small and medium-sized enterprises.Therefore, new requirements are put forward for the noise control of explosion-proof motors. The noise level has gradually become one of the important factors for students to choose and purchase explosion-proof motors.For some small and medium-sized explosion-proof motors, rolling bearings are mainly used, and the necessary lubrication is provided by grease, which may cause greater mechanical noise.In addition, compared with other noise forms such as ventilation noise, there are more reasons for mechanical noise, and it is more difficult to solve.

The main reason for the mechanical noise of explosion-proof motors and how to effectively control the noise has become one of the problems in the explosion-proof motor industry.The main cause of explosion-proof motor noise is mechanical noise.Mechanical noise is mainly the bearing noise generated when the motor is working, the motor rotor vibration noise, the friction noise generated by the contact between the brush and the commutator, and the end cover vibration noise caused by the bearing vibration.Bearing noise is one of the important sources of explosion-proof motor noise.After understanding the reasons for the mechanical noise of explosion-proof motors, I believe that the noise problem of explosion-proof motors will be imminent, and it will be a milestone in the innovation of the explosion-proof motor industry.
