I. The Roots blower produces noise when it is working.

Its main sources are:

1. Mechanical noise of the blower itself: including gear transmission, motor operation, friction of mechanical parts, etc.

2. Gas flow noise: Noise caused by the flow of gas inside the blower.

II. The Roots blower will produce vibration during operation.

Its main sources are:

1. Unbalanced vibration: vibration caused by low manufacturing accuracy or unstable installation of parts.

2. Damping vibration: vibration caused by air flow inside the Roots blower. Long-term vibration can accelerate the wear of Roots blower components, reduce their service life, and even lead to equipment failure.

III. Effects of cooling methods on noise and vibration

I. Direct air cooling method

Direct air cooling is the direct exposure of Roots fans to natural air, through the convection of air to reduce the temperature. This cooling method is simple and economical, but the noise and vibration control effect is poor.

2. Water cooling method

Water cooling is the use of water circulation system to conduct the heat of the Roots blower to the water, thereby reducing the temperature of the blower. This cooling method can effectively reduce the temperature of the Roots blower and reduce noise and vibration.

Three.

3. Oil cooling method

Oil cooling is the use of oil cooling system to absorb and distribute the heat of Roots blower, so as to achieve the purpose of reducing the temperature of the blower. This cooling method can effectively reduce noise and vibration levels, and improve the working efficiency and service life of the equipment.

IV. Conclusion:

Roots blower is an important industrial equipment, but its noise and vibration problems have been troubling users. By studying different cooling methods, we found that water cooling and oil cooling can effectively reduce the temperature of Roots blower and reduce noise and vibration. In addition, the use of highly efficient sound insulation materials can also provide a better working environment.
