Exhaust fans as ventilation and ventilation equipment, especially in restaurants, hotels and other places is very common. However, when the exhaust fan works, it will produce large vibration noise and airflow noise, which is easy to cause trouble to customers and nearby residents. How to reduce the vibration of exhaust fan and thus reduce the noise has become a key project of noise reduction and vibration reduction manufacturers.
How to reduce noise and vibration of exhaust fan?
1. Install sound insulation cover, which is a common method in industrial noise management. It can effectively reduce the overall noise of the exhaust fan by about 30 decibels, but attention should be paid to leaving ventilation and heat dissipation port to facilitate the maintenance and overhaul of the exhaust fan in the later period.
2. When the exhaust fan produces noise when working, the muffler can be installed at the inlet and outlet. If the exhaust fan pipeline also produces vibration, the fan pipeline can be wrapped with sound insulation materials. This method can greatly reduce the noise.
3. If it is the vibration noise of the exhaust fan, it is necessary to install the vibration isolator in the base at this time, so as to avoid the noise caused by the vibration of the fan.
Of course, it can not exclude the cause of the fault of the exhaust fan, such as the noise caused by the fault, timely maintenance can be done. In a word, if you want to solve the problem of vibration and noise of exhaust fan, the key is to suit the case.
