Technical field
The present invention relates to Compressor Technology field, particularly relate to a kind of screw compressor.
Background technology
As it is shown in figure 1, the exhaust process of existing screw compressor (especially high back pressure screw compressor) is: high pressure cold
Gas body is directly discharged to the epicoele (expansion cavity 3) of the enclosed formation of top cover 2 of quiet dish 1 and compressor from the air vent 11 of quiet dish 1
In, then it is discharged to the cavity of resorption of housing 9, through exhaustor 20 row by the exhaust passage 10 of quiet dish 1, upper bracket 8 and housing 9 composition
Going out, in Fig. 1, shown in arrow, direction is airflow direction.
There is pressure fluctuation in gases at high pressure when air vent 11 is discharged, thus produces noise；The height discharged from air vent 11
Pressure high-speed gas can be directly sprayed onto on the top cover 2 of compressor, causes vibration the radiated noise of top cover 2.Gas noise and
Top cover vibration radiation noise is the Main Noise Sources of screw compressor.Although the epicoele of quiet dish 1 and top cover 2 composition is equivalent to one
Expansion chamber acoustic filter, has certain noise elimination effect, but due to the restriction of structure space, its frequency of noise elimination and sound deadening capacity are limited,
Screw compressor pneumatic noise and the big problem of vibration radiation noise cannot be solved；Expansion cavity length mainly affects the maximum of epicoele
Frequency of noise elimination, the bandwidth lost by frequency (i.e. noise elimination low ebb frequency) and transmission, but due to structural volume and design requirement
Restriction, cause the sound deadening capacity of epicoele and frequency of noise elimination very limited；Although exhaust noise is had necessarily by the noise elimination structure of epicoele
Reduction effect, but due to exist eliminate the noise by frequency (noise elimination low ebb), the soundproof effect causing epicoele is very limited.

2, form expansion cavity 3 between quiet dish 1 and top cover 2, quiet dish 1 is provided with silencing apparatus 4, adopts between silencing apparatus 4 and quiet dish 1
Connect with the modes such as screw are fixing.The lower expansion cavity 32 of formation crowded around by silencing apparatus 4 and quiet dish 1, and expansion cavity 3 removes lower expansion cavity 32
Space form expansion cavity 31；Be provided with at least one through hole 41 on silencing apparatus 4, the upper expansion cavity 31 of through hole 41 connection and under
Expansion cavity 32.
Expansion cavity 3 on the quiet dish 1 of this silencing apparatus 4 is separated into two chambers, arrow institute in gas flow such as Fig. 2
Showing, the high-voltage high-speed gas gas pressure pulsation after lower expansion cavity 32 discharged from the air vent 11 of quiet dish 1 reduces, noise fall
Low, this air-flow is discharged to expansion cavity 31 by through hole 41 again, vibration when the less gas of pressure fluctuation is sprayed onto the top cover 2 of compressor
Also can reduce, correspondingly radiated noise reduces, and then air-flow is again by quiet dish 1, upper bracket 8 and the exhaust passage of housing 9 composition
10 cavity of resorptions being discharged to housing 9, discharge through exhaustor 20.The low ebb frequency of acoustic filter is eliminated by the quantity increasing expansion cavity
Rate, has reached to improve the purpose of compressor sound deadening capacity.
Original expansion cavity 3 is divided into the expansion chambers cavity of two series connection, lower expansion cavity 32 and upper expansion cavity by silencing apparatus 4
The height of 31 is different.Correspondingly, the part noise elimination low ebb frequency of silencing apparatus 4 can change, and reduces part in prior art
The noise of noise elimination low ebb frequency.Wherein, the height H of lower expansion cavity 32 and the design of the height L of upper expansion cavity 31 are mainly according to row
The peak value frequency range of gas noise is designed, and the height H of lower expansion cavity 32 is greater than expansion cavity 31 height L.
In view of the quantity increasing expansion cavity can only cut down the part low ebb frequency of silencing apparatus 4, in order to preferably cut down more
Many low ebbs frequency, can be respectively provided with interpolation pipe in lower expansion cavity 32 and upper expansion cavity 31；Can also be: silencing apparatus 4 is
Tipping upside down on the barrel-like structure on quiet dish 1 end face, through hole 41 is opened on the bottom surface of barrel-like structure, is provided with hollow in through hole 41
Tubulose intubate 5, intubate 5 be welded on through hole 41 in or with through hole 41 interference fit, the one end intubating 5 protrudes from silencing apparatus 4
The medial surface of bottom surface, the other end protrude from the lateral surface of bottom surface of silencing apparatus 4.
The length intubating 5 insertion expansion cavities mainly determines according to the crest frequency of exhaust noise to be eliminated, excellent
Choosing, intubate 0.25 times or 0.5 of the height H that height is lower expansion cavity 32 in the 5 inside bottom surface faces protruding from silencing apparatus 4
Times, specifically 0.25 times or 0.5 times then to select according to frequency of noise elimination；And/or, intubate 5 and protrude from silencing apparatus 4
The height in outer side bottom surface face is 0.25 times or 0.5 times of the height L of upper expansion cavity 31, then wants for specifically 0.25 times or 0.5 times
Select according to frequency of noise elimination.
Intubate shape and the quantity of 5 not limit, reasonable disposition can be carried out according to deadening frequency band.Intubate the cross section shape of 5
Shape can be the shapes such as circular, ellipse and rectangle；Intubate the quantity of 5 no less than one in the case of, all intubate 5 transversal
Area sum is more than or equal to the cross-sectional area of air vent 11, to reduce airflow pressure losses.
At the node location of the glottis neoplasms that through hole 41 (and intubating 5) is positioned at lower expansion cavity 32.This node in different product
Position is the most different, needs to carry out acoustics emulation in advance and determines this node location.
