Measures:
1, the installation of muffler
The main source of noise is the air inlet and outlet, should be used appropriate air inlet and outlet muffler. Air compressor air intake noise spectrum is low-frequency characteristics, the air intake muffler should be selected with a resistive structure or a, resistive-based impedance composite structure. The exhaust air pressure of the air compressor is large, the air velocity is high, should be used in the air compressor exhaust port small hole muffler.
2, set the muffler pit
Muffler pit underground or semi-underground pit, pit wall with sound-absorbing good brick masonry. The air inlet pipe of the air compressor is connected to the anechoic pit, so that the air enters the air compressor through the anechoic pit. The use of muffling pit can make the air intake noise of the air compressor is greatly reduced, the service life is also longer than the general muffler
3, the establishment of the acoustic enclosure
In the air compressor's air intake and exhaust port after the installation of the muffler or muffling pit, the noise of the airflow can be reduced to 80db (a) below, but the mechanical noise of the air compressor and the motor noise is still very high, so it should also be installed in the air compressor's mechanical noise and motor noise, so the air compressor's mechanical noise and motor noise is still very high. But the mechanical noise and motor noise of the air compressor are still very high, so the acoustic enclosure should also be installed on the air compressor unit.
4, hanging space sound-absorbing body
In Foshan Lingge wind compressor station, the high and empty plant reverberation is very heavy. If the roof of the plant scattered hanging sound-absorbing body, plant noise can be reduced by 3-10db (a), reverberation time is reduced by 5-10s.
Air compressor usual maintenance matters:
1, carefully read the randomly attached "Use and Maintenance Manual" and according to this maintenance.
2, strictly in accordance with the provisions of the replacement of three filters (air filter, oil filter, oil and gas separator). Replacement cycle in accordance with the requirements of the manual.
3, often check the operation of the oil tank oil level is in the middle of the normal position of the oil mirror.
Daily maintenance matters
1, check the air filter element and coolant level.
2. Check hoses and all pipe fittings for leaks.
3, check the record, if the consumable parts have reached the replacement cycle must be stopped to be replaced.
4, check the records, when the host exhaust temperature reaches or close to 98 degrees, you must clean the oil cooler.
5, check the condensate discharge, if you find the drainage is too small or no condensate discharge, you must stop to clean the water separator.
Monthly maintenance matters
1, check the surface of the oil cooler, if necessary, be cleaned.
2. Clean the after-cooler.
3. Check all wire connections and tighten them.
4, clean the motor suction port surface and shell surface dust.
5, clean the oil return filter.
