Description
Technical field
The utility model relates to technical field of refrigeration compressors, particularly a kind of compressor air suction silencer.
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.
Working procedure from compressor, because sucking the pressure of refrigeration agent, compressor is in the circular wave state, very strong gas is arranged, can produce air-breathing vibrations, these vibrations are main causes 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.Suck vibrations generation vibrating noise in order to reduce compressor, normally at the outdoor silencing apparatus that adds of the suction and discharge of cylinder head, but the inlet of this silencing apparatus is not provided with wind-guiding device, the intake grill place can produce as eddy current cyclone the tornado during use, the vibration that spreads out of when being accompanied by compressor operating has formed new noise source.
The model utility content
In order to solve the noise problem that inhaling silencer intake grill place exists in the prior art, a kind of compressor air suction silencer of the utility model design with rubber corrugated pipe.
The utility model is realized by following technical solution:
A kind of compressor air suction silencer with rubber corrugated pipe, it is installed on the lower casing inboard of refrigeration compressor, front device as compressor air suction, its effect is to reduce the noise that is produced by compressor air suction, it has a muffler body, and muffler body is provided with give vent to anger device and air intake, and the air outlet is connected with the induction chamber of compressor, air intake places near the air-breathing mouth of pipe of compressor lower shell body, it is characterized in that:
Air intake place in muffler body is provided with a joint, the outer tubaeform rubber corrugated pipe that connects of joint, the end that tubaeform rubber corrugated pipe is connected with joint is designed to elbow-shaped, makes the air-breathing mouth of pipe of the horn mouth of tubaeform rubber corrugated pipe over against the compressor lower shell body.
As optimization, the HNBR rubber material of the preferred high temperature resistant anti-refrigeration agent of described tubaeform rubber corrugated pipe is made.
During use, rubber corrugated pipe can play the guiding role to air-flow, the air whirl noise that produces when reducing the air suction silencer air inlet, and reduce the noise that transmits out from compressor.
The beneficial effects of the utility model are: reduce the compressor air suction loss, reducing inhalation temperature, when improving refrigerating capacity, avoid the direct transmission of compressor noise, also reduced the noise and the consequent vibration at intakeport place.
Description of drawings
Fig. 1 is the suction tude sectional view on interior air suction silencer of prior art compressor and the housing;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a rubber corrugated pipe sectional view of the present utility model;
Fig. 4 is the left view of Fig. 3.
Among the figure: 1-rubber corrugated pipe, 2-air suction silencer main body, 3-compressor housing, 4-sucking pipe, 21-bend pipe, 22-joint.
The arrow indication is an airflow direction among the figure.
Embodiment
Fig. 1 is that the air suction silencer suction port docks schematic representation with sucking pipe in the prior art compressor; The suction port place of air suction silencer 2 is connected with one 90 ° of bend pipes 21, the mouth of pipe of bend pipe 21 is over against the mouth of pipe of answering the sucking pipe 4 on the housing 3 and spaced apart, the air outlet of air suction silencer 2 connects the suction chamber (not marking among the figure) of compressor air intake valve, during compressor operating, the refrigeration agent of gasification is sucked in the space that housing 3 surrounded by sucking pipe 4, and the vaporizing system cryogen enters the compressor compresses chamber from bend pipe 21 through behind the air suction silencers 2 more then.Since spaced apart and do not establish wind-guiding device between the import of air suction silencer 2 and the sucking pipe 4, therefore be easy to generate intake swirl, thus the generation noise, the noise during compressor operating also can directly transmit out.
As shown in Figure 2, be a possible embodiments of the present utility model, it makes improvements compressor air suction silencer as shown in Figure 1, change former bend pipe 21 into joint 22, one end of joint 22 is connected with the suction port of air suction silencer main body 2, the other end of joint 22 connects a tubaeform rubber corrugated pipe 1, the end that tubaeform rubber corrugated pipe 1 is connected with joint 22 also is designed to elbow-shaped, the mouth of pipe that during installation the horn mouth of rubber corrugated pipe 1 is faced toward the sucking pipe 4 on (perhaps contacting) housing 3, but do not form a fixed connection, the air outlet of air suction silencer 2 connects the suction chamber (not marking among the figure) of compressor air intake valve, during compressor operating, the refrigeration agent of gasification is sucked in the housing 3 by sucking pipe 4 and directly enters rubber corrugated pipe 1, passes through air suction silencer 2 again, enters the compressor compresses chamber.
The intake swirl noise that such design produces in the time of can eliminating air inlet directly transmits the noise of coming out when also having prevented compressor operating.
