To effectively reduce the noise of Roots blowers, it is first necessary to understand the main source of noise.
The noise of Roots blowers usually comes from the following aspects:
1. Mechanical noise
Mechanical noise is mainly caused by the movement and friction of the internal parts of the blower, including:
Bearing vibration
Gear engagement
Change of clearance between rotor and housing
2. Airflow noise
Air flow noise is generated by the gas flow and compression process inside the blower, mainly including:
Turbulent air flow at inlet and outlet
Pulsation during gas compression
Gas leakage between impeller and housing
3. Motor noise
The motor that drives Roots blowers is also an important source of noise, mainly including:
The sound of the motor itself
Coupling vibration of motor and blower
4. Resonant noise
When the blower's operating frequency is close to the natural frequency of other equipment or building structures, resonance may occur, resulting in increased noise.
In view of the above noise sources, we can take the following measures to effectively reduce the noise of Roots blowers:
1. Optimize the mechanical structure
Use high-precision machining technology to improve the matching accuracy of parts
Use high quality bearings to reduce running noise
Optimized clearance design between rotor and housing to reduce gas leakage
2. Improve the airflow channel
Optimize the design of inlet and outlet to reduce airflow turbulence
Use a silencer or muffler to absorb airflow noise
Install expansion joints in the piping system to reduce vibration transmission
3. Motor noise reduction measures
Choose low noise motor
Use an elastic coupling to reduce motor vibration transmission to the blower
Install motor soundproof cover
4. Sound insulation and vibration reduction treatment
Install a vibration cushion or damper on the blower base
Use soundproof enclosures or soundproof rooms to encapsulate the entire blower system
The surrounding walls and ceilings were treated with sound-absorbing materials
