Description
Technical field
Utility model is related to compressor silencer technical field, particularly a kind of to reduce the secondary of freezer compressor noise
Expanding air suction silencer.
Background technology
Flow noise is compressor Main Noise Sources, and the suction noise of compressor is the main component of flow noise.Cause
The suction noise of this reduction compressor will directly reduce the overall noise of compressor, and suction noise mainly passes through air-breathing noise reduction
Device is reduced.Root is it was found that when compressor is matched with refrigerator body, noise is to noise of refrigerator shadow at 630Hz and 800Hz frequency ranges
Sound is the most obvious.But existing compressor silencer, it is impossible to effectively reduce noise at 630Hz and 800Hz frequency ranges, cause noise reduction
Effect is not good, and the noise problem is fed back when being matched with refrigerator body becomes apparent.
The content of the invention
To solve the problems of the prior art, it is easy, inexpensive, good muffling effect that the utility model provides a kind of assembling
The quadratic extension formula air suction silencer of freezer compressor noise can be reduced.
It is to solve above-mentioned technical problem the technical solution of the utility model：It is a kind of to reduce the two of freezer compressor noise
Secondary expanding air suction silencer, including epicoele, iron wire, pipeline, cavity of resorption, it is characterised in that：The epicoele bottom is provided with counterbore
First, neck, push rod one, the pipeline are made up of upper pipeline and lower pipeline, be provided with the upper pipeline conduit one, dividing plate one,
It is provided with deep gouge one, extension mouth one, the lower pipeline inside conduit two, neck two, extension mouth two, the cavity of resorption and is provided with counterbore
2nd, oil leaking hole, push rod two, dividing plate two；The neck and the phase of counterbore one of the dividing plate one and conduit one of the upper pipeline respectively with epicoele
Coordinate and be fixed on upper intracavitary by upper pipeline is horizontal, the conduit two and neck two of the lower pipeline respectively with the counterbore two of cavity of resorption and every
Plate two is engaged and is fixed on lower intracavitary by lower pipeline is horizontal；The upper pipeline and lower pipeline are combined into pipeline by deep gouge one, institute
State epicoele and cavity of resorption and welded together by iron wire and be combined into muffler.
The upper pipeline and lower pipeline of the push rod one and push rod two respectively with pipeline are inconsistent.
The oil leaking hole is arranged on the cavity of resorption bottom of the both sides of dividing plate two.
The utility model muffler will be divided into two expansion chambers by dividing plate inside it, horizontal pipeline is in two chambers up and down
Inside respectively there is an extension mouth, respectively there is an oil leaking hole cavity of resorption dividing plate both sides, and refrigerant gas stream is made by the frequency that disappears of quadratic extension room
With reaching effectively reduces the purpose of compressor 630Hz and 800Hz band noise.
The beneficial effects of the utility model are：The utility model is entered by the air suction silencer to Piston Refrigerant Compreessor
Row is improved, it is not necessary to change original pump body structure or housing, so that it may effectively reduce compressor 630Hz and 800Hz frequency range and make an uproar
Sound.The utility model is simple in construction, it is easy make, it is easy to assembly, therefore with wide market prospects.
