Why the smoke exhaust fan should not be equipped with vibration reduction device, the reasons are as follows:
1. Smoke exhaust fan is an emergency mechanical equipment used under special circumstances, which is usually used in fire accidents and emergencies, so the vibration and noise generated by mechanical equipment during operation are not necessarily considered.
2. The key purpose of shock absorber is to prevent or reduce solid-state sound, but in fire accidents and emergencies, it is not easy to care about the harm of noise; Moreover, when installing, several shock absorbers have a common fault point, which will bring inconvenience to maintenance, so there is no need for shock absorbers. Another function of the shock absorber is to reduce the damage to the fan, not to mention that the fan itself will have seismic performance parameters, and the fan will only start when there is a fire accident. Only the fan is used with the air conditioning unit. Because air conditioning is a common machine, the harm of solid-state sound caused by equipment vibration should be considered.
