How does a clean room centrifugal blower fan achieve silent energy savings? May 15, 2018

Clean room centrifugal blower fans have special occasions, so their requirements are also higher than those of ordinary centrifugal blowers. From the aspect of noise, in order to create a good environment for clean rooms, centrifugal blowers in clean rooms are required to have good Silent effect.

 

Therefore, it is necessary to combine clean room centrifugal blower fan noise reduction and energy saving in the process. After practice, the process arrangement for the clean room remains unchanged. Centrifugal air blowers in the clean room are placed in the soundproof room, and they are connected to the main engine with ventilation ducts. Air inlets are set on the top of the sound insulation room or on the wall surface. Install a muffler for use in the air intake of the engine room.

 

In the plane layout, the clean room centrifugal blower fan is close to the clean room side, the air inlet is on the upwind side, and the motor is placed in the middle of the air flow channel. As the clean room centrifugal blower generates negative pressure in the soundproof room, a large amount of outdoor fresh air will automatically enter the soundproof room.

 

In the design and construction, noise intensity, sound frequency and other factors should be considered according to specific requirements, and sound insulation, sound absorption, and ventilation and heat dissipation should be designed in detail, and details should be handled. The size and thickness of the soundproof room, the type and thickness of the sound absorption material are calculated. In the clean room, the muffler volume of the centrifugal muffler of the air intake muffler is generally about 25 dB, and the noise radiation area is minimized; and unnecessary metal plate surfaces are removed.

 

The clean room centrifugal blower fan connection pipes and thin-walled steel chimneys are the weak links for noise control. The 5cm thick glass fiber cotton is wrapped in the pipe wall and fastened with steel wire and then brushed with 2cm thick wire mesh cement. The glass fiber cotton is fixed on the steel plate to absorb the reverberation noise in the sound insulation room.

 

During the installation and operation of the clean room centrifugal blower, care must be taken to reduce the risk of rust removal on some joints. Dripping should be done with grease or engine oil. At the same time check the inside of the casing and other casings, there should be no falling or leftover tools or sundries.

 

At the same time, the horizontal position of the centrifugal blower main shaft of the clean room shall be ensured, and the concentricity of the main shaft and the motor shaft and the parallelism of both ends of the coupling shall be measured. When installing the clean room centrifugal blower inlet and outlet piping, the weight should not be added to the housing.
