Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
According to compressor silencer of the present invention; As shown in Figure 1; Comprise upper strata expansion cavity 10 that is arranged on compressor silencer top and the lower floor's expansion cavity 20 that is arranged on compressor silencer below; The shape of upper strata expansion cavity 10 is different with the shape of lower floor expansion cavity 20, is provided with intermediate clapboard 30 between upper strata expansion cavity 10 and the lower floor's expansion cavity 20, and intermediate clapboard 30 is provided with gas stream through hole 31.
For simple expansion cavity, there is the formula of following expanssion type silencing apparatus:
Wherein, TL represents sound deadening capacity, m representative expansion section ratio, l
2Represent the length of expansion cavity, k is a constant.
Can know expansion cavity section ratio decision sound deadening capacity through formula; The length decision frequency of noise elimination of expansion cavity; After knowing that so the frequency band that need to reduce is the exhaust sound frequency range, be that the shape of expansion cavity designs silencing apparatus according to the size of the formula preliminary definition expansion cavity of expanssion type silencing apparatus.
In the present embodiment; Be provided with intermediate clapboard 30 in the compressor silencer; Intermediate clapboard 30 is divided into upper strata expansion cavity 10 and lower floor's expansion cavity 20 with the inner chamber of compressor silencer, high pressure draught through lower floor's expansion cavity 20 backs through the gas stream through hole on the intermediate clapboard 30 to upper strata expansion cavity 10, the upper strata expansion cavity 10 of silencer is different with the shape of lower floor expansion cavity 20; So the frequency band at the noise elimination low ebb place of upper strata expansion cavity 10 and lower floor expansion cavity 20 is also different; Two expansion cavity series connection can be eliminated some noise elimination low ebb frequencies, thereby improve the noise elimination effect of compressor.
As shown in Figure 2, lower floor's expansion cavity 20 is a cylindrical structural, and upper strata expansion cavity 10 is a pintongs shape structure.
According to one embodiment of present invention, with upper strata expansion cavity 10 be set to pintongs shape structure, lower floor's expansion cavity 20 is set to cylindrical structural, the two shape is different, can eliminate noise elimination low ebb frequency.
Preferably, the compressor silencer also comprises interpolation pipe 32, and interpolation pipe 32 is arranged in the gas stream through hole 31, and the hole wall of its outer side wall and gas stream through hole 31 fits tightly.The length that interpolation pipe 32 stretches into upper strata expansion cavity 10 is height half the of upper strata expansion cavity 10.The length that interpolation pipe 32 stretches into lower floor's expansion cavity 20 is height half the of lower floor's expansion cavity 20.
The structure of interpolation pipe 32 and intermediate clapboard 30 such as Fig. 4 and shown in Figure 5, interpolation pipe 32 are arranged in the gas stream through hole 31, and gas stream through hole 31 and the position of interpolation pipe 32 on intermediate clapboard 30 can be confirmed according to the acoustic mode attitude of lower floor's expansion cavity 20.Shown in the transmission loss curve synoptic diagram that interpolation pipe 32 and no interpolation pipe are arranged of compressor silencer as shown in Figure 7, under all constant prerequisite of other structures, there be the sound deadening capacity of silencing apparatus in the 500Hz-3000Hz frequency range of interpolation pipe 32 to increase.
High pressure draught is through passing through the interpolation pipe 32 inflow upper strata expansion cavities 10 on the intermediate clapboard 30 behind the expansion cavity of lower floor's expansion cavity 20; The length that interpolation pipe stretches into upper strata expansion cavity 10 is height half the of upper strata expansion cavity 10, and the length that stretches into lower floor's expansion cavity 20 is height half the of lower floor's expansion cavity 20.Formula according to aforesaid expanssion type silencing apparatus can be known: if original setting is the hole, add that now interpolation pipe 32 and its length are set to a half of expansion cavity length, can improve sound deadening capacity on the basis of original gas stream through hole 31.
Like Fig. 4 and shown in Figure 5, the cross section of interpolation pipe 32 is circular arc.Interpolation pipe 32 is one-body molded with intermediate clapboard 30.
According to one embodiment of present invention, the sectional shape of interpolation pipe 32 is a circular arc, and interpolation pipe 32 simple shape of this kind sectional shape are easy to manufacture.Interpolation pipe 32 can integratedly machine with intermediate clapboard 30, further enhances productivity, and reduces cost; Intermediate clapboard 30 combines to constitute double-deck silencer through welding with the silencer shell.In other embodiments of the invention, interpolation pipe 32 also can be set to other shapes.
Like Fig. 2, Fig. 3 and shown in Figure 6, the outlet 11 of compressor silencer is arranged on the side of upper strata expansion cavity 10.
Because the spatial limitation under the upper flange 50 of compressor and the rotor between the equilibrium block 60, in order to reduce the secondary noise, with silencing apparatus export 11 be arranged on upper strata expansion cavity 10 the side, just this silencer is a side relief opening silencer.
Preferably, gas stream through hole 31 is arranged on the axle journal place of the upper flange of compressor.
Gas stream through hole 31 and interpolation pipe 32 can confirm that in the position of intermediate clapboard 30 position of the interpolation pipe 32 that provides among Fig. 1 is at the axle journal place of upper flange 50 according to the acoustic mode attitude of lower floor's expansion cavity 20.Interpolation pipe 32 positions among Fig. 1 are one embodiment of the present of invention, also can interpolation pipe 32 be arranged on other positions of intermediate clapboard 30.
The present invention also provides a kind of compressor, comprises aforesaid compressor silencer.
The compressor silencer is described in detail in the above-described embodiments, is not described in detail in this.Compressor has comprised the compressor silencer, thereby can in wider frequency, improve sound deadening capacity, thereby reduces the noise of compressor, promotes customer experience.
The miscellaneous part of compressor of the present invention is a conventional components of the prior art, also no longer details at this.Be provided with the compressor of this compressor silencer; Make the angle of rotatable parts of compressor obtain accurate more control; Like this; Also make compressor under the situation that start runs well, shutdown is out of service, the parts of compressor and the overall co-ordination of complete machine more coordination, more perfect function, control more accurate.
From above description, can find out that the above embodiments of the present invention have realized following technique effect:
Compressor silencer of the present invention and have the compressor of this silencer; Its upper strata expansion cavity is different with the shape of lower floor's expansion cavity; So the frequency band at the noise elimination low ebb of upper strata expansion cavity and lower floor expansion cavity place is also different; Two expansion cavity series connection can be eliminated some noise elimination low ebb frequencies, thereby improve the noise elimination effect of compressor.
More than be merely the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
