What are the noise reduction methods for air compressors?
Air compressors are widely used mechanical equipment at the moment. The noise generated by the operation of air compressors cannot be ignored, which seriously affects the surrounding environment and the physical and mental health of workers. It is imperative to reduce the noise of setting up a compressor. So what are the effective methods for air compressor noise reduction?
Air compressor noise reduction method
1. Air compressor noise reduction method-muffler
A muffler is installed at the air inlet. Because the intake noise has low-frequency characteristics, it is generally equipped with an impedance composite muffler, a micro-perforated plate composite muffler, a venturi muffler, etc.
2. Air compressor noise reduction method-shock absorption
Carry out shock absorption treatment on the machine base, carry out shock absorption design and selection of shock absorption products according to the weight and vibration frequency of the air compressor.
3. Air compressor noise reduction method-sound insulation cover
The air compressor is equipped with a sound insulation cover, and the design of the sound insulation cover must ensure its airtightness in order to obtain a good sound insulation effect. At the same time, the heat dissipation of the unit should be considered, and mufflers should be installed at the air inlet and outlet.
4. Air compressor noise reduction method-gas storage tank
The noise control of the gas storage tank can be used to suspend the sound absorption body in the gas storage tank, and the sound absorption effect of the sound absorption body is used to hinder the formation of standing waves in the tank, so as to achieve the purpose of sound absorption and noise reduction.
Precautions for long-term parking of setting up a compressor
Shutdown of setting up a compressor often occurs in various departments. Then, before the first start-up of the air compressor for more than three months, or the air compressor is out of use for more than three months, measures must be taken before restarting, and professional air compressor personnel must be asked to maintain the equipment. Detect and formulate safety precautions to prevent poor conditions after booting.
1. First check the circuit status to see if everything is supplied normally and the working voltage is stable; the insulation resistance of the motor is accurately measured, and the standard value exceeds 1MΩ.
2. Check whether there is water and dust on the parts of the air compressor, and remove them immediately.
3. All-round detection of the air inlet and exhaust outlet to avoid blockage
4. The power can be turned on after the above has been completed, and the control panel on the computer can be inquired whether everything is operating normally
5. Disassemble and replace the three filters and lubricating oil. Due to the long-term unused condition, the three-filter oil is likely to be aging, which will cause the air compressor to gel and deposit or block soon after it is started up. The oil passage is blocked and the air compressor or other parts are destroyed.
6. Debugging by technical professional staff, manual intervention after hydropower transformation, loading and unloading, first running at no-load for more than ten minutes, testing all kinds of index values and vibration, noise, etc., and then loading, and querying all components It's normal.
