How to mute the sound of centrifugal fan
When the noise produced by the equipment is strictly required in the indoor or surrounding environment, in addition to reducing the vibration and reducing the noise of the centrifugal fan, the noise suppression and sound insulation treatment should also be carried out.
The centrifugal fan is usually treated with sound insulation box. According to the type and size of the fan, the centrifugal fan insulation box makes the cover body of various shapes. It is composed of a number of standard or non-standard sound insulation plate splicing, can also be made into an integral mask. The cover body leaves out the fan in and out of the tuyere and the inspection door, and all other parts are closed. The exhaust pipe is installed at the top of the hood to eliminate the heat released from the motor running.
Centrifugal fan sound insulation method:
1. reduce the noise of centrifugal fan outlet, and install muffler in the inlet and outlet pipe of the fan.
2. The centrifugal fan unit is equipped with sound insulation cover to solve the noise source of fan housing, motor, foundation vibration and so on.
3. the fan unit should be enclosed in the fan room so that the noise can not be transmitted out, and the air inlet muffler should be installed on the sealed air room to supply the fan suction and the need of heat dissipation such as the motor and the housing.
Centrifugal fan is a kind of driven fluid machinery, which depends on the input mechanical energy to increase the gas pressure and exhaust the gas. Centrifugal fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and ventilation of boilers and industrial kilns.www.jnblower.com
