Abstract

The invention discloses a suction structure of a refrigeration compressor, which comprises a bellows and a suction muffler, the bellows is connected to the suction muffler or is in line contact with the suction muffler, and the suction muffler includes a suction pipeline 1 and an expansion chamber , Suction pipeline 2, suction pipeline 3 and resonance chamber, suction pipeline 1, expansion chamber and suction pipeline 2 are connected in series, suction pipeline 3 is connected with the resonance chamber to form a resonance chamber assembly , the other end of the suction line 3 is connected with the suction line 1 or the suction line 2, the first-order resonance frequency of the resonant cavity assembly is between 80 and 210 Hz, and the suction muffler is connected with the bellows The first and second resonance frequencies of the structure are respectively between 45 and 160 Hz. The present invention not only has the effect of noise reduction and shock absorption, but also has a stable suction boosting effect, can greatly improve the refrigeration performance of a refrigeration compressor, and can be reliably and stably realized in a specific process.

Description

technical field [0001] The invention relates to a suction structure applied to a fully enclosed refrigerating compressor, in particular to a connection structure of an airflow pipeline from a compressor suction pipe to a suction valve plate. Background technique [0002] Refrigeration performance and noise level are two important indicators to measure the performance of hermetic refrigeration compressors. Reasonable compressor suction structure design, including suction muffler, bellows, etc., can well reduce the noise generated by the compressor when suction, and 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. Therefore, designing a reasonable compressor suction structure will help improve the overall performance of the compressor and redu...
