Abstract

The invention discloses a hush pipe connecting structure applied to a compressor silencer. The hush pipe structure comprises a compressor silencing cavity body and an air flow passage, and further comprises at least two hush pipes, wherein the hush pipes are connected with the compressor silencing cavity body and the air flow passage in parallel, and the sum of the volumes of the hush pipes is far smaller than the volume of the compressor silencing cavity body. The hush pipe connecting structure overcomes the defects of a traditional compressor silencer, effectively improves the silencing capacity of the silencer, widens the silencing frequency band to a certain degree, can adjust the silencing frequency, and improves the silencing effect of the compressor silencer.

Description

For the hush pipe linkage structure of compressor silencer
Technical field
The present invention relates to a kind of hush pipe linkage structure for compressor silencer.
Background technique
The hush pipe aperture of compressor silencer is general less, its sound-damping qualities is very responsive to the volume size of compressor cavity, slightly increasing volume within the specific limits can make sound-damping qualities significantly improve, but baffler is selective to frequency, general less in the hush pipe aperture designed high frequency noise, but sound-damping qualities is less.
As shown in Figure 1, usual compression muffler structure connects compressor silencing cavity cavity 1 and air-flow path 2 by hush pipe 3 single tube, the length of hush pipe 3 is t, section area is S, and compressor silencing cavity cavity 1 volume is V, requires that compressor silencing cavity cavity 1 volume is much larger than hush pipe 3 volume; This conventional muffler structure is once after design processes, its noise reduction frequency bandwidth is little, and not easily regulates noise reduction frequency on the original basis, in the R&D process of compressor, causes the waste of component sometimes and delays product development progress.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hush pipe linkage structure for compressor silencer, this hush pipe linkage structure overcomes the defect of traditional compressor baffler, effectively improve the sound-damping qualities of baffler, expansion noise reduction frequency band, and voice frequency enforcement adjustment can be offseted, improve the erasure effect of compressor silencer.
For solving the problems of the technologies described above, the hush pipe linkage structure that the present invention is used for compressor silencer comprises compressor silencing cavity cavity and air-flow path, also comprise at least two hush pipes, described at least two hush pipes are connected in parallel described compressor silencing cavity cavity and air-flow path, and the volume sum of described at least two hush pipes is much smaller than the volume of described compressor silencing cavity cavity.
Further, the section area of described at least two hush pipes is equal or not etc.
Further, the length of described at least two hush pipes is equal or not etc.
Further, the sectional shape of described at least two hush pipes is circular, square, semicircle or triangle.
The hush pipe linkage structure being used for compressor silencer due to the present invention have employed technique scheme, namely this hush pipe linkage structure comprises compressor silencing cavity cavity and air-flow path, also comprise at least two hush pipes, described at least two hush pipes are connected in parallel described compressor silencing cavity cavity and air-flow path, and the volume sum of described at least two hush pipes is much smaller than the volume of described compressor silencing cavity cavity.This hush pipe linkage structure overcomes the defect of traditional compressor baffler, effectively improves the sound-damping qualities of baffler, expands noise reduction frequency band to a certain extent, and can offset voice frequency enforcement adjustment, improves the erasure effect of compressor silencer.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is the linkage structure schematic diagram of hush pipe in conventional compression baffler;
Fig. 2 is the hush pipe linkage structure schematic diagram of the present invention for compressor silencer;
Fig. 3 is the schematic diagram that in this hush pipe linkage structure, hush pipe section area does not wait, length is equal;
Fig. 4 be in this hush pipe linkage structure hush pipe length do not wait, section area schematic diagram not etc.;
Fig. 5 is the schematic diagram that in this hush pipe linkage structure, three hush pipes connect;
Fig. 6 is the comparison diagram of traditional hush pipe structure and this hush pipe linkage structure acoustic damping characteristic.
Embodiment
As shown in Figures 2 to 5, the hush pipe linkage structure that the present invention is used for compressor silencer comprises compressor silencing cavity cavity 1 and air-flow path 2, also comprise at least two hush pipes 3, described at least two hush pipes 3 are connected in parallel described compressor silencing cavity cavity 1 and air-flow path 2, and the volume sum of described at least two hush pipes 3 is much smaller than the volume of described compressor silencing cavity cavity 1.
Further, the section area of described at least two hush pipes 3 is equal or not etc.
Further, the length of described at least two hush pipes 3 is equal or not etc.
Further, the sectional shape of described at least two hush pipes 3 is circular, square, semicircle or triangle.
The present invention changes the linkage structure of hush pipe in traditional compressor baffler, at least two hush pipes are adopted to be connected in parallel compressor silencing cavity cavity and air-flow path, thus effectively improve the sound-damping qualities of baffler, simultaneously according to the needs of compressor noise reduction, at least two hush pipes adopt section area equal or not etc., length is equal or not etc., reach expansion noise reduction frequency band, regulate the object of noise reduction frequency, improve the erasure effect of compressor silencer.
As shown in Figure 6, curve 4 is the acoustic damping characteristic curve of traditional single tube hush pipe, and its noise reduction resonant frequency is 3610Hz, and sound-damping qualities is about 15dB; Curve 5 is the acoustic damping characteristic curve of two uniform sections in the present invention, isometric hush pipe, and its noise reduction resonant frequency is 5134Hz, and sound-damping qualities is about 18dB; Curve 6 is the acoustic damping characteristic curve of two unequal sections in the present invention, isometric hush pipe, and its noise reduction resonant frequency is 4723Hz, and sound-damping qualities is about 22dB; Curve 7 is the acoustic damping characteristic curve of hush pipe of two unequal sections in the present invention, Length discrepancy, and its noise reduction resonant frequency is 4553Hz, and sound-damping qualities is about 24dB.Obtain thus, by the setting of hush pipe parameter in this hush pipe linkage structure, improve the sound-damping qualities of baffler, expand noise reduction frequency band simultaneously, noise reduction frequency-adjustable, thus the erasure effect improving baffler, can adapt to the research and development of compressor in time, avoid component to waste, accelerate product development progress.
