Problems solved by technology

However, as compressor users have higher and higher requirements for low noise, and there are more and more types of suction mufflers, although the above-mentioned structural improvements can reduce noise, they will increase the suction resistance of the suction muffler. Reduce the overall performance of the compressor, it is difficult to meet the requirements of low noise and high efficiency at the same time

Embodiment Construction

[0014] Such as figure 2 As shown, the separator inner tube structure of the compressor suction muffler of the present invention includes a first separator 3, a first inner tube 11, a second separator 5 and a second inner tube 12, and the first inner tube Tube 11 is U-shaped (see also Figure 4 ), which is located on the first partition 3. The second inner insertion tube 12 is bent, and it is arranged on the second partition 5 . The lengths of the two arms of the first intubation tube 11 are adjusted according to the frequency bands that the muffler needs to eliminate noise, so that the noise elimination of the secondary frequency bands can be taken into account when eliminating the noise of the main frequency bands. The first partition 3, the second partition 5 and the muffler housing 6 are connected by direct buckling (please also refer to figure 1 ), the second partition 5 divides the interior of the muffler into two chambers, and the first partition 3 divides the muffle...

Abstract

The invention discloses a partition board and inner insertion tube structure of an air suction silencer for a compressor. The partition board and inner insertion tube structure comprises a first partition board, a first inner insertion tube, a second partition board and a second inner insertion tube, wherein the first inner insertion tube and the second inner insertion tube are respectively arranged on the first partition board and the second partition board; the suction inlet in the lower end of the first inner insertion tube is arranged over against the air suction hole of the air suction silencer; and the opening in the upper end of the first inner insertion tube is arranged over against the suction inlet in the lower end of the second inner insertion tube. The partition board and inner insertion tube structure provided by the invention can effectively meet the performance requirements of noise reduction and high efficiency and is especially suitable for be applied to a high-noise totally-closed refrigeration compressor.

Description

technical field [0001] The invention relates to an inserting tube structure in a partition used in a plastic suction muffler of a fully enclosed refrigeration compressor. Background technique [0002] For hermetic refrigeration compressors, noise has always been an important indicator to measure their performance. The application of the suction muffler can better reduce the noise generated by the compressor when it is suctioning, and it can also have a good noise reduction effect on the noise of the valve plate beating the valve seat. But on the other hand, the use of a suction muffler will increase the flow loss of the refrigerant suction port to a certain extent and reduce the overall performance of the compressor. The main noise frequency bands produced by different types of compressors are also different. Therefore, a reasonable design of the internal structure of the compressor suction muffler is helpful to improve the overall performance of the compressor and reduce ...
