With the development of economy and technology, the application scope of vacuum pump is more and more extensive. It plays an important role in the process of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing.
In addition, it also has the characteristics of compact structure, reliable working balance and uniform flow, but the efficiency of the vacuum pump is relatively low, which is mainly due to the large amount of energy lost by the impeller in the process of mixing liquid. In the process of long-term use, some parts of the vacuum pump will be damaged. When the damage reaches a certain degree, there will be screams and vibrations, and the wear of the motor bearing or shaft is the main reason. Therefore, it is necessary to check all parts of the pump and replace the damaged parts.
In addition, if there is solid entering the pump cavity, blocking it will also cause this phenomenon. What needs to be done is to remove the debris in the pump cavity. If the shaft center of the pump body and the motor of the vacuum pump is used without alignment, it will easily cause the coupling to wear, and noise and vibration will appear after Z. therefore, the shaft center of the pump body and the motor must be corrected, and the coupling can also be replaced.
There is another situation that will also cause noise and vibration of the vacuum pump. That is, when the vacuum is too large, this noise is harsh. Therefore, when you hear the harsh sound, it is likely that the vacuum is too large. At this time, you need to open the pneumatic valve of the vacuum pump and put some air in it.
