Abstract
The invention discloses a silencer of a refrigeration compressor, which comprises a hollow silencer main body in which at least one anechoic chamber is formed, wherein the silencer main body is provided with a refrigerant inlet tube which has a horn-shaped air-sucking collection port communicated with a refrigerant supply system of the compressor; a refrigerant flows into the refrigerant inlet tube from the horn-shaped air-sucking collection port and then is introduced into the anechoic chamber; a plurality of drain holes are formed on the horn-shaped wall face of the horn-shaped air-sucking collection port; and after the refrigerant flows through the horn-shaped air-sucking collection port, a liquid substance drains from the drain holes, while the gas refrigerant flows into the refrigerant inlet tube and then enters the anechoic chamber. By reserving the drain holes and by using the principle that the inertia of the liquid substances such as refrigerated machine oil and the liquid refrigerant is bigger than that of the gas substance, various liquid substances are separated from a gas medium before entering a silencer cavity, so that the amount of the liquid substance which enters a piston chamber is reduced, the probability of liquid impact is reduced, and the service life of the compressor is prolonged.
Description
Technical field
The present invention relates to the baffler that a kind of refrigeration compressor is used.
Background technique
In the prior art, for reducing chiller plant as the noise of refrigerator, air conditioner, usual way is, at compressor, baffler is installed.The baffler using on compressor is mainly used for changing the flow direction of compressor assembly, to improve the Energy Efficiency Ratio COP value of compressor, noise decrease.Baffler is conventionally by baffler body, baffler lid and be located at respectively baffler body, the suction covering, outlet pipe and form.In general the air-breathing mouthful liquid sucking of collecting by baffler body enters the liquid hit phenomenon that cause in compressor piston chamber, can cause compressor total failure, and consequence is serious.
Summary of the invention
The object of this invention is to provide a kind of optimal design to existing fluid path.
For achieving the above object, the technical solution used in the present invention is: a kind of silencer of refrigeration compressor, comprise the inner hollow silencing device body that at least limits Yi Ge anechoic chamber, on described baffler body, be provided with one and enter pipe for refrigeration agent refrigeration agent being introduced in described anechoic chamber, described refrigeration agent enters pipe and has the tubaeform air-breathing collection mouthful being connected with the refrigeration agent supply system of compressor, refrigeration agent flow into after described refrigeration agent enters pipe and is fed through in described anechoic chamber via described tubaeform air-breathing collection mouth, it is characterized in that: on the tubaeform wall of described tubaeform air-breathing collection mouth, offer a plurality of leakage openings, after refrigeration agent flows through from described tubaeform air-breathing collection mouth, liquid material will release from described leakage opening, gaseous refrigerant will be flowed through after described refrigeration agent enters pipe and be entered in described anechoic chamber.
Preferably, baffler body interior is provided with Liang Ge anechoic chamber, and Zhe Liangge anechoic chamber is realized and being connected by the coupling pipe of described baffler body interior.
Preferably, described leakage opening is offered along the approach axis of refrigeration agent.
The present invention compared with prior art, tool has the following advantages: leakage opening utilizes the liquid principles larger than the inertia of gaseous substance such as refrigerator oil, liquid refrigerant, various liquids were separated before entering muffler chamber from gaseous state media, greatly reduced the liquid quantity that enters piston cavity, reduce the probability of liquid hit phenomenon, extended the working life of compressor.

embodiment
Describe below with reference to accompanying drawings concrete structure of the present utility model in detail:
Shown in accompanying drawing 1, accompanying drawing 2: a kind of silencer of refrigeration compressor, comprise the inner hollow silencing device body 1 that at least limits Yi Ge anechoic chamber, baffler body 1 inside is provided with Liang Ge anechoic chamber 5, and Zhe Liangge anechoic chamber is realized and being connected by the coupling pipe of baffler body 1 inside.On baffler body 1, be provided with one and enter pipe 4 for refrigeration agent refrigeration agent being introduced in anechoic chamber, refrigeration agent enters pipe 4 and has the tubaeform air-breathing collection mouth 2 being connected with the refrigeration agent supply system of compressor, and refrigeration agent flow into after refrigeration agent enters pipe 4 and is fed through in described anechoic chamber via tubaeform air-breathing collection mouth 2.On the tubaeform wall of tubaeform air-breathing collection mouth 2, offer a plurality of leakage openings 3, leakage opening 3 is offered along the approach axis of refrigeration agent.
During normal work, when refrigeration agent arrives leakage opening 3, leakage opening 3 has utilized the liquid principles different from the momentum of gaseous state refrigerator such as refrigerator oil, liquid refrigerant, various liquids were separated before entering anechoic chamber 5 from gaseous state media, liquid refrigeration agent will release from leakage opening 3, and the refrigeration agent of gaseous state will be flowed through after refrigeration agent enters pipe 4 and be entered in described anechoic chamber 5.Therefore greatly reduce the liquid quantity that enters piston cavity, reduced the probability of liquid hit phenomenon.And, owing to having increased after leakage opening 3, on tubaeform air-breathing gas collection mouth 2, formed out-of-flatness surface, refrigeration agent forms turbulent flow on out-of-flatness surface, makes the gasification that liquid refrigerant is good, has improved the air-breathing mass dryness fraction of compressor, increase reliability, improved again efficiency.
Claims (2)
1. a silencer of refrigeration compressor, comprise the inner hollow silencing device body that at least limits Yi Ge anechoic chamber, on described baffler body, be provided with one and enter pipe for refrigeration agent refrigeration agent being introduced in described anechoic chamber, described refrigeration agent enters pipe and has the tubaeform air-breathing collection mouthful being connected with the refrigeration agent supply system of compressor, refrigeration agent flow into after described refrigeration agent enters pipe and is fed through in described anechoic chamber via described tubaeform air-breathing collection mouth, it is characterized in that: on the tubaeform wall of described tubaeform air-breathing collection mouth, offer a plurality of leakage openings, on the tubaeform wall of described tubaeform air-breathing collection mouth, form out-of-flatness surface, it is outside that the described tubaeform air-breathing tubaeform wall of collecting mouth is positioned at described anechoic chamber, described leakage opening is offered along the approach axis of refrigeration agent, after refrigeration agent flows through from described tubaeform air-breathing collection mouth, liquid refrigeration agent will release from described leakage opening, the refrigeration agent of gaseous state will be flowed through after described refrigeration agent enters pipe and be entered in described anechoic chamber.
