Description

technical field [0001] The invention relates to a reciprocating piston compressor, in particular to an energy-saving, noise-reducing, noise-reducing, and vibration-reducing reciprocating-piston compressor and a method for reducing noise and noise. Background technique [0002] In the prior art, the patent document No. 93112795.5 disclosed the technology of a noise reduction device for a hermetic reciprocating compressor on August 4, 1999. It is provided with an anti-noise chamber in the lower shell, and the anti-noise chamber is arranged outside the compressor. , and the muffler has only two stages, and a vibration isolator with elastic elements is also provided; since the noise-proof chamber needs to be welded with the lower shell, it must be ensured that the noise-proof chamber is well sealed. Generally, such weldments are made of metal materials. After analysis, the structure of this patented technology is complicated. It is installed in the outer anechoic chamber and has...

AI Technical Summary

Problems solved by technology

After analysis, the structure of this patented technology is complicated. It is set in the outer anechoic chamber and has elastic vibration isolation parts. The process is complicated. It is necessary to ensure that the welding of each part is reliable, and the pipeline is effectively inserted into the vibration isolation elastic parts.

At the same time, the muffler has only two stages, the amount of noise reduction is limited, and the metal material is not easily deformed compared with plastic, and its vibration isolation effect is not as good as that of plastic, and its noise reduction and vibration reduction effect will be further reduced.

[0003] At the same time, most of the suction mufflers of the prior art reciprocating piston compressors are two-stage mufflers. Because the muffler cavity is small and the compression ratio is limited, the noise reduction of the traditional muffler is limited. The volume is also small, and the specific volume of the suction working medium is large; at the same time, the suction port of the suction muffler has no baffle structure, and the refrigeration oil thrown by the crankshaft flows through the suction port with gravity, and the refrigeration oil is directly sucked into the compressor. However, since the refrigerating machine oil does not participate in the refrigerating cycle in the refrigerating system, it further reduces the suction density and further reduces the refrigerating capacity of the compressor.

As users have higher and higher requirements for energy efficiency ratio and lower and lower requirements for noise, the energy-saving, noise-reduction and noise-reduction effect of the compressor anechoic cavity in the traditional sense cannot meet the further requirements of customers for quality.
