Pneumatics machine regards a kind of air as power plant, it is equipment of a kind of strong noise. Pneumatics machine applies extensively in industrial domain, so if pneumatics engine noise is too big, can make the staff member produces dizziness, disgusting, the heartbeat passes fast, the symptom such as hypertension. Because this is right,pneumatics machine undertakes a confusion of voices is handled falling very be necessary.

Examine the equipment structure of a place with a draught of pneumatics machine pass in and out, for instance fan fan leaf has damaged to whether perhaps have slight collision attrition with fan cover, these metropolises cause noise. To the attrition noise of equipment, can increase or change lube, reduce the attrition noise of equipment. To the noise of air motive force of a place with a draught of pass in and out, can add outfit muffler, use porous sound absorption material to secure the wall in air current passageway to go up, block sex muffler is right in effect of noise elimination of high frequency noise is good.
2, pneumatics machine airframe
Be aimed at the oscillatory noise with pneumatics overall machine, the proposal installs damping base, can go up in certain level so slow down is oscillatory, reduce noise. Pneumatics machine often can give out very strong oscillatory noise, this moment is about to be adopted to the base of pneumatics machine decrease brace up processing, press the different and oscillatory frequency of machine according to different sky, still have the weight of the machine, model, will choose to be decreased suitably brace up product. Vibrating absorber and bedspring shock absorber can reduce oscillatory noise effectively. Administer pneumatics engine noise integratedly, can install acoustic hood, in-house in order to decrease brace up stuff stuff, prevent oscillatory sound wave to transmit.
3, structural design
Noise of pneumatics machine conduit is very serious also, because this wants to be adopted to conduit,decrease brace up design, can add orifice plate of outfit reduce expenditure inside vent-pipe usually, can feeling of shake of slow down vibration.
4, gas tank
Of pneumatics engine noise still having a source is the noise inside gas tank, we can be inside jar body of pensile sound absorption, those who use sound absorption system is sound-absorbing the effect, prevent the transmission of sound wave.
Of course, the product that the pneumatics aircraft manufacturer with the method with the simplest problem that should solve pneumatics engine noise from fountainhead or credible alternative produces.
