In industrial production,
Screw Air Compressor is an indispensable and important equipment, however, the excessive noise during its operation has become a nuisance for many enterprises. Excessive noise not only affects the working environment of employees, but also may cause harm to their health. As a professional screw air compressor manufacturer, Jiubei analyzes the root cause of noise and provides you with systematic and efficient solutions.
In-depth analysis of the causes of noise
(A) Mechanical components
Screw air compressor running for a long time, the internal bearings, gears and other key mechanical parts will be worn out, and the gap between the parts will become larger, resulting in impact and friction during the operation, which will cause noise; during the operation of the equipment, the fixing bolts and other connectors may be loose, resulting in increased overall vibration, which will cause noise. During the operation of the equipment, the fixed bolts and other connectors may loosen, resulting in an increase in overall vibration, triggering noise; rotor and other rotating parts if there is an imbalance, the operation will produce periodic strong vibration, bringing obvious noise.
(B) airflow factors
When the compressed air flow in the pipeline, unreasonable pipeline design, such as sudden changes in pipe diameter, too many bends, the airflow will form turbulence, resulting in airflow noise; if the compressor air inlet or exhaust port silencer is damaged, failure, and can not effectively reduce the high-speed flow of the gas generated by the noise, but also lead to noise increase.
(C) Electrical System Failure
In the electrical system, the electromagnetic noise generated by the motor operation is also one of the sources of noise. Short-circuiting of motor windings, loose wiring, or wear and tear of motor bearings will cause electromagnetic noise to increase abnormally.
(a) Mechanical Noise Management
Jiubei technical team will use professional testing equipment, such as vibration detector, infrared thermal imager, etc., to conduct a comprehensive inspection of the compressor, and accurately locate the mechanical parts of the problem. For bearings and gears that are badly worn out, we will replace them with high-quality parts that meet the original factory standards; for loose bolts and other connecting parts, we will tighten them in strict accordance with the torque stipulated in the equipment manual; and if we find that the rotor is unbalanced, we will use advanced dynamic balancing and correction technology to adjust the rotor to achieve a balanced state, which can effectively reduce the vibration and noise of the mechanical parts.
(B) Airflow Noise Optimization
Jiubei will evaluate and optimize the piping system according to the actual working conditions of the enterprise. Through reasonable adjustment of piping direction, we reduce unnecessary bends and sudden changes in piping diameter to reduce airflow resistance and turbulence; we replace or repair damaged silencers for enterprises, and select high-performance silencing materials and scientific structural design to effectively absorb and reduce airflow noise; we also optimize compressor air inlet and exhaust ports to ensure that the gas flows in and out smoothly to reduce the noise generated.
(C) Electrical Noise Overhaul
Jiubei electrical engineers will carry out insulation testing and troubleshooting of motor windings, repairing short circuits, loosening and other problems; replacing worn-out motor bearings in a timely manner, and carrying out comprehensive maintenance on motors to ensure stable motor operation and control electromagnetic noise within the normal range. Although the problem of noisy screw air compressor is complicated, JOBE, with its professional technology and rich experience, is able to provide enterprises with practical and effective solutions to help them create a quiet and efficient production environment and guarantee smooth production.
