Background technique
Air suction silencer is applied in the hermetically sealed compressor, general employing heat-insulating property plastic materials is preferably made, being in order to reduce noise on the one hand, is in order to reduce the heat effect of compressor heat to refrigeration agent, to improve the gettering efficiency of compressor on the other hand.Existing air suction silencer has two silencing cavity and a suction line usually.Along with the compressor user is more and more higher to the requirement that reduces noise, in order to reduce noise, the air suction silencer that has at present reduces noise with three even more silencing cavity, the extend length of whole suction line of the employing that has reduces noise, the complex-shaped suction line (as S shape) of the employing that has reduces noise, and the cross section that the employing that also has reduces suction line reduces noise.Above-mentioned several architecture advances can reduce noise really, but all can increase inhalation resistance, reduces the gettering efficiency of compressor, is difficult to reach simultaneously the requirement of raising the efficiency and reducing noise two aspects.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of air suction silencer with dual filter screen that can reach better gettering efficiency and noise reduction.
For solving the problems of the technologies described above, suction muffler for compressor of the present invention comprises loam cake, suction conduit assembly and lower casing, cover on described and be provided with sucking pipe, described lower casing is provided with intakeport and sucking pipe, described intakeport, sucking pipe, suction conduit assembly and described on the sucking pipe that covers formed the air-breathing path of refrigeration agent, dividing plate on the described suction conduit assembly is divided into left silencing cavity and right silencing cavity with the baffler inner chamber, and the suction conduit assembly in the described left silencing cavity is provided with two or more by-pass ports.
The above-mentioned compressor air suction silencer, the suction conduit assembly in the described right silencing cavity is provided with two or more by-pass ports.
The above-mentioned compressor air suction silencer, it also includes filter screen, and described filter screen is located in the described suction conduit assembly.
Above-mentioned compressor air suction silencer, described filter screen are located between two and half sucking pipes of described suction conduit assembly.
Above-mentioned compressor air suction silencer, described filter screen have two, and wherein another filter screen is located in the step hole of described suction conduit assembly upper end.
Above-mentioned compressor air suction silencer, described suction conduit assembly are provided with projection and compress the inwall of described lower casing, and described lower casing is provided with a convex tendon and compresses the outer wall of described suction conduit assembly.
The above-mentioned compressor air suction silencer, described suction conduit assembly is made up of two and half sucking pipes, and it is shaped as L shaped, U-shaped, W shape or S shape.
Because the present invention has adopted technique scheme, it utilizes the air-breathing path design of the suction line assembly and the dual filter screen of two silencing cavity, many by-pass ports, thereby adjustment that can be by following three aspects and optimize and reach the effect of raising the efficiency and reducing noise: length, sectional area and the shape of 1, adjusting air-breathing path (sucking pipe, suction conduit assembly and on the sucking pipe that covers), 2, adjust the area of by-pass port, 3, pass through to select the filter screen of different meshes, thereby make the present invention can reach better gettering efficiency and noise reduction.Contrast after tested, the gettering efficiency of air suction silencer of the present invention can reach equal even better level, and the overall noise of compressor reduces about 3dB.
