Abstract
The utility model discloses a plastic suction muffler used for hermetic compressors, which comprises an upper cover, a suction pipe assembly, a lower housing, a suction pipe arranged on the upper cover, and a suction port and a suction pipe both arranged on the lower housing. The suction port, suction pipes, suction pipe assembly and the suction pipe on the upper cover combine to form a refrigerant suction passage. The suction pipe assembly is provided thereon with a baffle for dividing the inner cavity of the muffler into a left muffling chamber and a left muffing chamber. More than two bypass ports are received on each of the parts of suction pipe assembly inside the left and right muffling chamber respectively. The utility model can regulate and optimize the sectional areas of the suction pipes and the bypass pipe, thereby ensuring good suction efficiency and noise reduction effect.
Description
Technical field
The utility model relates to a kind of plastics air suction silencer that is applied to hermetically sealed compressor.
Background technique
Hermetically sealed compressor uses reed Aspirating valves and outlet valve to carry out the suction and the compression of refrigeration agent usually.Because the air-breathing and compression process of compressor is periodic, and is discontinuous, so periodic, the discontinuous fluctuation of meeting generation in transmission course of the refrigeration agent of compressor, this is the main source of compressor noise.In order to reduce noise, hermetically sealed compressor is provided with air suction silencer and muffler usually.Because the heat that produces during compressor operating can produce heat effect to the refrigeration agent that sucks, the density that causes sucking gas reduces, thereby reduces the gettering efficiency of compressor.Therefore, air suction silencer often adopt heat-insulating property preferably plastic materials make, on the one hand be in order to reduce noise, be in order to reduce the heat effect of compressor heat, to improve the gettering efficiency of compressor on the other hand to refrigeration agent.The plastics air suction silencer that present high-efficient compressor has generally adopted can be improved gettering efficiency, reduce noise.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 suction line of the employing bending that has (as S shape) 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, but all can increase inhalation resistance, reduces the gettering efficiency of compressor, is difficult to reach simultaneously raise the efficiency and reduce noise two aspects and look for requirement.
Summary of the invention
It is a kind of by optimizing suction line sectional area and by-pass port area thereof to reach the better gettering efficiency and the plastics air suction silencer that is applied to totally-enclosed compressor of noise reduction that technical problem to be solved in the utility model is to provide.
For solving the problems of the technologies described above, the plastics air suction silencer that the utility model is applied to totally-enclosed compressor 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, on the suction conduit assembly in the described left silencing cavity two or more by-pass ports is arranged.
The above-mentioned plastics air suction silencer that is applied to totally-enclosed compressor, it also comprises filter screen, described filter screen is located in the step hole of described suction conduit assembly upper end.
The above-mentioned plastics air suction silencer that is applied to totally-enclosed compressor, the sucking pipe of described loam cake enters the step hole wind of described suction conduit assembly, and compresses described filter screen.
The above-mentioned plastics air suction silencer that is applied to totally-enclosed compressor, 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 plastics air suction silencer that is applied to totally-enclosed compressor, described suction conduit assembly is made up of two and half sucking pipes, and it is shaped as L shaped, U-shaped or S shape.
Because the utility model adopts two silencing cavity and a cover to have the suction line assembly of four above by-pass ports, thereby can pass through to adjust length, sectional area and the shape in air-breathing path (loam cake sucking pipe, suction conduit assembly and lower casing sucking pipe) to improve the gettering efficiency of compressor; Can reduce the noise of compressor by the area of adjusting by-pass port.Adjustment and optimization by this two aspect can reach the excellent effect of raising the efficiency and reducing noise.
