Abstract
The utility model relates to a siphon suction silencer for a compressor. The siphon suction silencer comprises an upper cover(2), a clapboard(3) and a lower cavity(1), and is characterized in that an air suction pipe(7)takes the shape of a siphon. An air suction port(6)is aligned with the air intake port of the compressor; refrigerant flows steadily in the siphon and cushions effectively, thus reducing the noise caused by the pulsating movement of the air flow. Refrigerant gas runs through an upper hollow cavity and the lower hollow cavity and expands therein, thus reducing the air suction load of the compressor and reducing the noise caused by the fluctuation of pressure. The refrigerant flows in the entire pipeline and reduces the noise of the whole compressor through above effective method.
Description
Technical field
The utility model relates to a kind of compressor bend pipe air suction silencer, is applicable in the totally-enclosed reciprocating type freezer compressor to use.
Background technique
Fast development and user's improving constantly along with refrigeration industry for the refrigeration appliance requirement, the user more and more pursues the chiller plant of low noise, the refrigerator industry has now been released super-silent refrigerator, and as " heart " of refrigerator, the noise of compressor requires also to improve constantly thereupon.The full enclosed type reciprocating compressor is in running, connecting rod-piston moves reciprocatingly, the suction and the compression of refrigeration agent finished in the unlatching of Aspirating valves and outlet valve, under specified frequency, air-breathing-compression process is not continuous, just periodic, when the valve block cycle opens and closes, at air valve mouth place, gas handling system is produced velocity fluctuation, pressure pulsation and the gas noise that a corresponding cycle changes, and the gas noise that therefore solves compressor is most important to the reduction of the complete machine noise of compressor.In the prior art, when compressor operating, the compressed machine sucking pipe of low-temperature low-pressure refrigerant that flows out from vaporizer sucks, and directly enters compressor muffler lower chamber cavity, and cushioning effect is limited, influences the baffler effect.
Summary of the invention
It is a kind of simple in structure, easy to use that the utility model purpose is to provide, and is issued to the bend pipe air suction silencer of best noise reduction in the prerequisite that does not reduce compressor efficiency.
The utility model is realized by following technical solution: compressor bend pipe air suction silencer, comprise loam cake, dividing plate and lower chamber three parts, one cavity A is arranged in the loam cake, one cavity B is arranged in the lower chamber, cavity B is provided with the sucking pipe of UNICOM with it, it is characterized in that described sucking pipe shape is an elbow-shaped.
The preferred R=36mm of sucking pipe crooked radian, noise reduction the best.
Between cavity A and cavity B, the dividing plate guiding tube is set, because the dividing plate guiding tube can directly import refrigeration agent cavity A, thereby reduced the loss of gas in runner, refrigerant gas is through two cavitys of A, B, gas expands and has reduced the IL of compressor, reaches more effective noise reduction.
When compressor operating, the compressed machine sucking pipe of low-temperature low-pressure refrigerant that flows out from vaporizer sucks, enter the intakeport of compressor with the bend pipe baffler, refrigerant vapor effectively cushions through the bending sucking pipe, reduces gas, carries out acoustic attenuation, the noise that pressure surge is caused reduces, under the prerequisite that does not influence original windage loss, effectively eliminate the noise effect that gas brings, thereby reach noise reduction.

Fig. 2 cuts open for the A-A direction of Fig. 3 and shows structural representation;
Fig. 3 is a longitudinal profile structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing, the utility model comprises loam cake 2, dividing plate 3 and lower chamber 1 three parts, on be stamped the outlet 6 that is connected with compresser cylinder, lower chamber has the sucking pipe 7 of a bending, loam cake and lower chamber are by the 4 fixing butt joints of baffler rivet, dividing plate is closely cooperated by the inner ring of loam cake and the step of lower chamber, dividing plate is divided into A with baffler, two cavitys of B, dividing plate 3 is provided with gas guiding tube 5, guiding tube 5 is with A, two cavitys of B effectively are communicated with, the compressed machine sucking pipe of refrigeration agent sucks, enter the intakeport 8 of compressor, after entering bending sucking pipe 7 and effectively cushioning, flow into lower chamber cavity B with the bend pipe baffler, enter loam cake inner cavity A through dividing plate guiding tube 5, refrigerant vapor is through A, effective acoustic attenuation of two cavitys of B is after the air outlet in the cavity A flows into cylinder of compressor.
