Abstract
The invention relates to parts in refrigeration compressors, in particular to an air suction silencer for a compressor. The air suction silencer for the compressor comprises an upper cavity and a lower cavity, a protruded air suction port is designed at the top of the upper cavity, a communicated tube is installed in the lower cavity, a corrugated pipe which right faces to a lower horn mouth of the communicated tube is arranged on the outside of the lower cavity, a partition board is installed between the upper and lower cavities, and an upper end of the communicated tube penetrates through the partition board to be disposed in the upper cavity. The air suction silencer for the compressor is characterized in that an inclined steel wire gauze which is close to one side of the air suction port is installed in the upper cavity. The air suction silencer for the compressor has the advantages that air flow passing through an upper silencing chamber is smooth, the air suction work is stable, the air suction efficiency is improved, and the air suction silencer is suitable for air suction silencing of the refrigeration compressors.
Description
(i) technical field: the present invention relates to the component in refrigeration compressor, especially a kind of suction muffler for compressor.
(ii) background technique: for hermetically sealed compressor, the refrigeration agent that inlet temperature is lower is conducive to improve the air input efficiency of compressor.Therefore, at present the air suction silencer of hermetically sealed compressor with thermoinsulation material preferably plastics make, most bafflers have also adopted direct air-breathing technology simultaneously, reduce the temperature that sucks refrigeration agent.But connecting tube is unsettled installation in the prior art, different lower anechoic chambers connect, and the steel wire in upper cavity is to be laid in above dividing plate, and therefore existing baffler working stability is good not, the air-flow smoothness is undesirable, and the efficiency that finally affects compressor improves.
(iii) summary of the invention: it is undesirable with baffler air-flow smoothness that purpose of the present invention will overcome existing refrigeration compressor exactly, and the imperfect problem of working stability, provide a kind of suction muffler for compressor.
Concrete scheme of the present invention is: for existing baffler, improved, it includes upper and lower cavity, top design at upper cavity has protruding intakeport, connecting tube is installed in lower chamber, lower horn mouth in the lower chamber outside over against connecting tube is equipped with bellows, and between upper and lower cavity, dividing plate is housed, connecting tube upper end be placed in upper cavity through dividing plate, it is characterized in that: in upper cavity, by intakeport one side, the steel wire be in tilted layout is installed.
The angle α of steel wire described in the present invention and dividing plate is 10-45 °.
The inner spout of bellows described in the present invention stretches in the horn mouth of connecting tube lower end, and the external diameter of bellows inner spout is less than bell-mouthed internal diameter of connecting tube.
The lower end of connecting tube described in the present invention adopts draw-in groove to coordinate location with the lower chamber inwall.
A blowdown pipe is installed described in the present invention in lower chamber, and the lower end mouth of blowdown pipe is communicated with the lower chamber outside, the height of blowdown pipe>=
?the interior outage degree of lower chamber.
The present invention, owing to adopting the inclination steel mesh structure, has strengthened the area of steel wire, makes by the air-flow of upper anechoic chamber more steady.By connecting tube horn mouth dock and work in coordination with the gap of bellows, improved gettering efficiency.By connecting tube and lower chamber, adopt draw-in groove to coordinate, strengthened being communicated with the intensity of sucking pipe, improved air-breathing stability.By installing blowdown pipe additional, make when compressor moves under normal operating condition, can be by the direct lower refrigeration agent from the suction tude inlet temperature of air suction silencer.When compressor needs larger displacement, by blowdown pipe, from the compressor inner chamber, the refrigeration agent that inlet temperature is higher, by the temperature in the bottom silencer chamber, lower refrigeration agent is squeezed into sucking pipe to warm refrigerant.
By above design, guaranteed that the compression function moves under stable state, the refrigeration agent that inlet temperature is lower, thus reach the optimization of compressor air input efficiency.

(v) embodiment:
Referring to Fig. 1,2,3, upper and lower cavity 1 and 6 have been the present invention includes, top design at upper cavity 1 has protruding intakeport 2, connecting tube 5 is installed in lower chamber 6 is interior, lower horn mouth in lower chamber 6 outsides over against connecting tube 5 is equipped with bellows 10, the inner spout 12 of this bellows 10 stretches in the horn mouth 11 of connecting tube 5 lower end, and keeps the external diameter of bellows inner spout 12 to be less than connecting tube horn mouth 11 internal diameter.And between upper and lower cavity 1 and 6, dividing plate 4 is housed, connecting tube 5, upper end was placed in upper cavity 1 through dividing plate 4, particularly: by intakeport 2 one sides, the steel wire 3 be in tilted layout is installed in upper cavity 1, steel wire 3 is 10-45 ° with the angle α of dividing plate 4, concrete optional 30 °.
The lower end of connecting tube described in the present embodiment 5 adopts draw-in groove to coordinate location with lower chamber 6 inwalls.Be designed with dop 8 in the lower end of connecting tube 5, and be designed with groove 7 in lower chamber 6 inwall correspondences, referring to Fig. 3, dop 8 and groove 7 coordinate location.
A blowdown pipe 9 also is installed in the present embodiment in lower chamber 6, and the lower end mouth of blowdown pipe 9 is communicated with lower chamber 6 outsides, the height of blowdown pipe 9 by>=
?the interior outage degree design of lower chamber 6.Form the present invention.
