Embodiment Construction

[0027] The technical solutions claimed in this application will be further described in detail in combination with the accompanying drawings and specific implementation methods.

[0028] In order to eliminate the noise generated when the compressor rotates, the present application discloses a sound-absorbing device for a rotary compressor to absorb and eliminate the noise generated when the compressor rotates. The structure of the sound-absorbing device combines figure 1 - Figure 5 As shown, it includes a casing 1 used to be set outside the cylinder of the rotor compressor, and the inner wall of the casing 1 is provided with a sound-absorbing material as a sound-absorbing layer 2; when the compressor rotates, the sound-absorbing material acts as a The sound-absorbing layer 2 absorbs the sound generated by the rotation of the compressor, thereby realizing noise elimination.

[0029] The shell 1 can adopt any shape that is rolled from a metal hot-rolled sheet or plastic inject...

Abstract

The invention discloses a rotor type compressor noise absorbing device. The device is used for eliminating noise generated during rotor type compressor rotation. The rotor type compressor noise absorbing device comprises a shell (1) used for sleeving a rotor type compressor barrel. A noise absorbing layer (2) is arranged on the inner side wall of the shell (1). The noise absorbing layer is used for absorbing the noise generated during compressor rotation, and the purpose of eliminating noise is achieved. The device is simple in structure, the noise lowering volume for specific frequency at 6.3K and 12.5 K can reach 5 decibels or above, and the total noise lowering volume of the whole machine can reach 5 decibels or above as well.

Description

technical field [0001] The invention relates to a sound absorbing device, in particular to a sound absorbing device for a rotary compressor. Background technique [0002] With the improvement of people's living standards, they are gradually pursuing a high-quality living environment. Among them, people's requirements for noise are getting higher and higher, and they prefer a warm and quiet environment. All kinds of noise are becoming more and more popular among the public. Attention and attention. Household air conditioners are a necessity in life, and almost every household has several units. In addition to having good performance and safety indicators, low noise must become the focus of attention, and it is also one of the important indicators to improve product market competitiveness. [0003] At present, the noise reduction method in the existing technology of compressor enterprises is mainly to achieve noise reduction by changing the structure of the compressor core an...
