Six Rules for Use of High Pressure Roots Blowers

At present, the Roots blower whose boost value is greater than 49KPa is generally regarded as the category of high-pressure Roots blower. High-pressure Roots blower is a kind of Roots blower. What are the requirements for the use of high-pressure Roots fans?
1. Flat washers and spring washers must be used to tighten the screws.
2. ** It is indispensable to use rubber buffer rubber to bear the weight of high-pressure fan, especially high-power high-pressure fan.
3. For some occasions where noise is required, mufflers can be installed to reduce noise (generally, about 5dB). The mufflers are installed at the end of the intake or outlet ducts.
4. For some occasions where the noise requirement is very high, the noise requirement of the scene can be met by adding a layer of silencing sponge according to the condition of the machine itself.
5. When using silencing cotton, pay attention to the distance between the high-pressure fan and the box, the ventilation and heat dissipation of the high-pressure fan, and the use of rubber buffer glue to bear the weight of the high-pressure fan.
6. Hose connections shall be used to isolate vibration when connecting the inlet and outlet pipes of high-pressure fans.
