The suction silencer for refrigeration compressors is characterized in that a separating filter screen is arranged between the air inlet pipe and the air outlet pipe inside the casing, a resonant cavity and a silencing board are arranged in the inner cavity of the casing, the casing is combined by a main casing and a cover, the air inlet pipe and the air outlet pipe are arranged inside the main casing, the resonant cavity and the silencing board are disposed on the cover, the filter screen is placed in after the main casing and the cover are molded respectively, thereby integrally hot welding or cementing the main casing and the cover together. The suction silencer for refrigeration compressors has a reasonable structure and excellent silence effect, overcomes the problem that impurity in a refrigeration pipeline enters a cylinder of a compressor, and increases usage rate of finished compressors.
Description
Technical field
The utility model relates to the air suction silencer that refrigeration compressor is used.
Background technique
The reciprocating hermetic compressor that chiller plant such as refrigerator, air conditioner uses generally all is equipped with suction muffler, to eliminate the voice that is produced in suction refrigerant process.In the prior art, various bafflers are arranged, its thinking is to increase silencing cavity and sound-absorbing baffler etc. is set in silencing cavity in the sucking pipe of compressor.
In refrigeration system, except compressor, also have equipment such as heat exchanger, gas-liquid separator, microcapillary, refrigerant line lead to/passes these equipment and constitutes the loop, in manufacturing and installation process, may there be foreign matter in the refrigerant circuit, even very fine hard foreign matter when entering into compresser cylinder, also can have a strong impact on the motion of cylinder piston, even the destruction cylinder, so that whole compressor is scrapped.
Increasing the foreign matter filtering function in air suction silencer is to prevent that foreign matter from entering the effective way of cylinder.
The model utility content
The purpose of this utility model has provided a kind of refrigeration compressor air suction silencer, and it is rational in infrastructure, and sound-absorbing effect is good, and also tool filters the function that foreign material avoid entering compresser cylinder.
The utility model is realized by following technical solution:
A kind of refrigeration compressor air suction silencer, comprise housing with inner chamber, housing is provided with suction port and air outlet, the housing inner chamber is put a suction tude and a steam outlet pipe, one end of suction tude is connected in the suction port place of housing, the external expansion mouth of suction port, one end of steam outlet pipe is connected in the place, air outlet of housing, suction tude and steam outlet pipe form gas channel by the housing inner chamber, steam outlet pipe connects one section by the air outlet and extends tracheae outside housing, extend the tracheae end and have cylinder head and connect dop, it is characterized in that: housing is provided with the separation filter screen between the suction tude of inner chamber and steam outlet pipe.
Optimal design is that housing is provided with resonant cavity at inner chamber.
Further optimizing is that housing is provided with at least 1 acoustical panel at inner chamber.
The housing that includes suction tude and steam outlet pipe manufactures an overall structure with plastics, be convenient manufacturing process, housing is by main casing and lid be combined into, suction tude and steam outlet pipe are positioned at main casing, resonant cavity and acoustical panel are positioned at and cover, and insert filter screen the heat seal weldering or the structure that is bonded into one again respectively after the moulding.
The utility model is rational in infrastructure, and good muffling effect has overcome the problem that foreign matter enters compresser cylinder in the refrigeration pipe, improves the use yield rate of compressor.
