Below with reference to Fig. 1-Fig. 3, the compressor according to this utility model embodiment is described.
Compressor according to this utility model embodiment, including: main body (not shown go out), main body has air entry and air vent, and air vent is connected to hush pipe 100.Compressor also includes reservoir, and reservoir is connected on the air entry of main body.
With reference to Fig. 1, hush pipe 100 includes: main siphunculus 10 and quarter-wave long tube 4, main siphunculus 10 is used for the coolant that circulates, main siphunculus 10 is equivalent to exhaustor disclosed in prior art, quarter-wave long tube 4 is blind pipe, one end of quarter-wave long tube 4 connects with main siphunculus 10, and the other end of quarter-wave long tube 4 is blind end.
Here, quarter-wave long tube 4 is a kind of reactive muffler, and quarter-wave long tube 4 is to utilize antiresonance principle abating noises.When sound wave enters in quarter-wave long tube 4 from main siphunculus 10, sound wave is closed end and reflects back into main siphunculus 10.When the cavity length of quarter-wave long tube 4 is equal to the 1/4 of the noise wavelength of some frequency range, the phase 180 degree of the echo of wavelength tube porch and incidence wave, form antiresonance, namely the sound wave that this frequency range is reflected back is cancelled out each other due to opposite in phase with the sound wave of same frequency range in main siphunculus 10, reaches the purpose eliminated the noise.So, wavelength is that the noise of four times of wavelength tube is maximum by the noise elimination amplitude of this wavelength tube.
By arranging quarter-wave long tube 4 in the exhaust ports of compressor, be equivalent to be provided with on the compressor exhaust muffling device, by rationally arranging the length of quarter-wave long tube 4, such as the length of quarter-wave long tube 4 is arranged to compressor produce maximum noise wavelength 1/4, then can reduce the discharge noise of compressor to greatest extent.
Quarter-wave long tube 4 is one section of blind pipe, and the setup cost of quarter-wave long tube 4 is relatively low, and whole hush pipe 100 can entirety be integrally machined, and is welded to connect after the processing of whole hush pipe 100 also sectional again.Relative to muffler parts such as expansion pipes, owing to the caliber of quarter-wave long tube 4 is less, if hush pipe 100 entirety is integrally machined, difficulty of processing is little, if be welded to connect after hush pipe 100 segmental machining, soldering opening is less again, connects operation also simple.
Compressor according to this utility model embodiment, by arranging quarter-wave long tube 4 on exhaustor, can improve the outside transmission of compressor air-discharging noise, reduce the exhaust noise that compressor is outwards transmitted by pipeline to greatest extent.And quarter-wave long tube 4 setup cost is low, pipeline processing, easy to manufacture.
Owing to noise proportion in the noise that compressor produces of the natural frequency section of compressor is relatively big, if therefore quarter-wave long tube 4 can eliminate as much as natural frequency section noise, then the discharge noise of compressor can be substantially reduced.Therefore, 1/4th of the wavelength of the natural frequency of the length preferred compressed machine of quarter-wave long tube 4.
Wherein, one of affecting parameters of natural frequency of compressor is the housing interior diameter of main body, and the housing interior diameter of main body is the interior diameter of the main casing of the known compressor of prior art.To in actual experiment Operation Summary, the inventors have also found that, when the length of quarter-wave long tube 4 is arranged to the 30%～70% of the housing interior diameter of main body, noise reduction is obvious.
