What causes the noise of the air compressor

The noise of the air compressor may be caused by the following reasons:

1. Internal factors of the equipment

1. Mechanical vibration noise:

   • Component wear: For example, the components of the screw air compressor’s yin and yang rotor, bearing, connecting rod bearing, piston and cylinder are worn after long-term use, resulting in an increase in the coordination gap and a large vibration and noise occur during operation.
   • Imbalance: The unbalanced workload of the compressor, such as excessive or too small, may cause mechanical vibration and thus produce noise.
   • Loose: Loosening of fixing bolts, nuts for fastening gears, etc. will cause impact and vibration between components and produce noise.

2. Gas flow noise:

   • Poor air intake: The air filter is blocked, resulting in a decrease in the intake amount, affecting the normal operation of the air compressor, thereby causing vibration noise.
   • Exhaust gas blocked: The exhaust valve is faulty or the exhaust pipeline is blocked, causing exhaust gas to be poor, causing pressure fluctuations and generating noise.
   • Gas Edges and Turbulence: The eddy currents and turbulence generated by gases when they flow in pipes and valves will cause air to vibrate and produce medium-frequency noise.

3. Motor noise:

   • Mechanical noise: Noise caused by friction and vibration of bearings, fans and other components when the motor is running.
   • Electromagnetic Noise: The noise caused by changes in the electromagnetic field inside the motor, although relatively small, may also affect the overall noise level in some cases.
   • Ventiation Noise: The noise generated when the motor cooling fan is running is usually high.

4. Fan and cooler noise:

   • The fans and coolers inside the compressor produce noise when they are running.

5. Equipment failure:

   • If the belt is too loose or the main or passive belt grooves are mismatched, it causes slipping and howling, and the air compressor fails to supply oil in time after starting, resulting in dry friction between metal parts.

2.External factors

1. Installation problems:

   • The foundation of the air compressor is not solid during installation, or the anchor bolts are loose, which makes it easy to cause greater vibration and noise during operation.
   • Unproper installation location, such as proximity to sensitive areas or places that are susceptible to interference, may also lead to increased noise problems.

2. Computer room environment:

   • The reflection effect of the computer room walls and ceiling on noise may make the noise more messy.
   • The layout in the computer room is unreasonable. If the distance between the equipment is too close, it may also cause noise to overlap and increase the noise level.

3. Poor lubrication:

   • Lack of sufficient lubricating oil or poor quality of lubricating oil cannot effectively reduce friction and wear between parts, resulting in noise.

3. Solution

For the above reasons, the following measures can be taken to reduce the noise of the air compressor:

1. Regular inspection and maintenance:

   • Conduct regular inspection and maintenance of the air compressor, and replace severely worn parts in a timely manner to ensure that the equipment is in a good condition.
   • Cleaning and replacing the air filter regularly, checking the exhaust valves and exhaust lines to ensure their normal operation.

2. Improve the installation conditions:

   • Ensure that the air compressor is installed firmly, the anchor bolts are tightened, and the use of shock absorbing pads and other devices to reduce the transmission of vibration and noise.
   • Select the installation location reasonably to avoid being close to sensitive areas or places that are susceptible to interference.

3. Optimize the computer room environment:

   • Please sound insulation of the computer room, such as installing sound insulation walls, sound insulation doors, etc.
   • Rank the equipment in the computer room rationally to ensure that the equipment is maintained at an appropriate distance and reduce the noise superimposed on each other.

4. Strengthen lubrication management:

   • Add an appropriate amount of high-quality lubricant in accordance with regulations, and regularly check and replace the lubricant.
   • Ensure that the lubrication system works properly and reduce friction and wear between parts.

In summary, the reasons for the high noise of the air compressor may involve multiple aspects such as internal factors and external factors of the equipment. By taking targeted measuresIt can effectively reduce the noise level of the air compressor and create a good working environment for employees.
