Abstract
The utility model relates to an exhaust silencing device in refrigeration compressor, which comprises an exhaust pipe (1), the exhaust pipe (1) is wound to special-shape spring structure, an end of the exhaust pipe (1) is connected with an exhaust silencer chamber cover (2), the exhaust pipe (1) is jacketed with a damping spring (3), a cavity enlarging type muffler (4) is connected with an end of the exhaust pipe (1) near the exhaust silencer chamber cover (2) in series. The utility model has the advantages that: due to the muffler on the exhaust pipe and the damping spring jacketed on the exhaust pipe, the compressor exhaust passes through the cavity enlarging type muffler, noise generated by exhaust can be reduced greatly, so overall noise of the compressor is improved.
Description
Technical field
The utility model relates to the exhaust muffling device of refrigeration compressor.
Background technique
Along with improving constantly of people's living standard, chiller plant such as refrigerator, air conditioner has been come into huge numbers of families, the noise that produces during chiller plant work is befouling environment not only, waste energy, and shortened working life of equipment, so, people more and more pursue the chiller plant of super low noise, one of main index noise level during as choosing equipment, equipment manufacturers are also reducing noise as one of important quality control index, in order to meet the need of market, so-called " super quiet " refrigerator and air conditioner appearred on the market.As everyone knows, the heart of chiller plant is a compressor, and the noise great majority of chiller plant are to produce in the compressor operation, or compressor operation is caused.Therefore, reduce the noise of chiller plant, at first should on the noise that reduces compressor, set about.
From the working procedure of above-mentioned compressor as can be seen, because the pressure of compressor discharge refrigeration agent is in the circular wave state, very strong gas is arranged, can produce exhaust shock, this exhaust shock is the main cause that compressor produces vibrating noise, these vibrating noises, the low frequency noise that produces with other parts of chiller plant is easy to generate resonance, has aggravated the noise and the vibration of whole chiller plant.Produce vibrating noise in order to reduce the compressor discharge vibrations, normally outside the drain tap of cylinder, enclose one or two simple and easy silencing apparatuss, but because this silencing apparatus is to be connected on the exhaust cavity of cylinder, and simple in structure, so erasure effect is not remarkable.
Summary of the invention
In order to solve the noise problem that exhaust produces in the refrigeration compressor that exists in the prior art, the utility model proposes exhaust muffling device in a kind of refrigeration compressor.
The utility model is realized by following technical solution:
Exhaust muffling device in a kind of refrigeration compressor, it has an outlet pipe, this outlet pipe coiled deformed spring shape structure, an end of outlet pipe is connected with the exhaust noise silencing chamber cap, it is characterized in that: the end by the exhaust noise silencing chamber cap on outlet pipe is serially connected with baffler.
Further design is an overcoat damping spring on described outlet pipe.
As optimization, baffler adopts cavity to enlarge the formula baffler.
During use, exhaust noise silencing chamber cap cover is connected on the exhaust noise silencing chamber of compresser cylinder, the outlet pipe latter end then is connected to compressor lower casing outlet pipe, and the exhaust that makes compresser cylinder is discharged to refrigeration system after by the utility model.
The beneficial effects of the utility model are: owing to increased baffler and at the damping spring of outlet pipe overcoat on outlet pipe, the exhaust of compressor enlarges the formula baffler through cavity, can significantly reduce the noise that exhaust produces, the compressor overall noise is improved.

Embodiment
Venting gas appliance in the prior art compressor as depicted in figs. 1 and 2 has an outlet pipe 1, and outlet pipe 1 coiled deformed spring shape structure is set with damping spring 3 on the outlet pipe 1, and an end of outlet pipe 1 is connected with an exhaust noise silencing chamber cap 2.During use with exhaust noise silencing chamber cap 2 housings on the exhaust noise silencing chamber of compresser cylinder, compressed High Temperature High Pressure refrigerant vapor through drain tap, enters exhaust chamber and noise elimination chamber cap 2 from pressing chamber, is sent to condenser by outlet pipe 1, carries out cooling liquid.
As shown in Figure 3 and Figure 4, the utility model makes improvements venting gas appliance in above-mentioned compressor: an outlet pipe 1 is arranged, outlet pipe 1 coiled deformed spring shape structure, be set with damping spring 3 on the outlet pipe 1, one end of outlet pipe 1 is connected with an exhaust noise silencing chamber cap 2, is enlarging formula baffler 4 by near the serial connection one cavity exhaust noise silencing chamber cap 2 on the outlet pipe 1.
Through actual measurement, through after the above-mentioned improvement, the noise of compressor assembly reduces the 3-5 decibel.
Claims (3)
1, exhaust muffling device in a kind of refrigeration compressor, it has an outlet pipe (1), outlet pipe (1) coiled deformed spring shape structure, one end of outlet pipe (1) connects exhaust noise silencing chamber cap (2), it is characterized in that: an end of going up by exhaust noise silencing chamber cap (2) at outlet pipe (1) is serially connected with baffler (4).
2, exhaust muffling device in the refrigeration compressor as claimed in claim 1 is characterized in that: go up overcoat damping spring (3) at described outlet pipe (1).
