Problems solved by technology

The thermal conductivity of the current compressor cylinder is relatively high. During the operation of the compressor, the heat in the high-temperature area of ​​the compressor shell is transferred to the compression cavity through the metal material of the cylinder, resulting in an increase in the temperature rise of the low-temperature cavity in the compressor cylinder, thereby reducing compression. Ratio, which in turn affects the performance of the compressor; in addition, the noise generated during the operation of the compressor is also transmitted to the outside of the casing through the cylinder, and the noise is large

The heat insulation and noise reduction part 5 is a material with low thermal conductivity and is installed on the surface of the cylinder body 1 or inside the cylinder body 1 to isolate the heat exchange ...

Embodiment 2

[0066] like figure 1 , 2 As shown, a compressor heat-insulating and sound-absorbing cylinder of the present invention includes a cylinder body 1, and the cylinder body 1 is provided with a compression chamber 2, an air intake hole 3 communicating with the compression chamber 2, and a sliding vane groove 4 communicating with the compression chamber 2 , and also includes a heat insulating and sound-absorbing member 5 for slowing down the heat exchange between the compression chamber 2 and the outside, and the heat-insulating and sound-absorbing member 5 is arranged on the cylinder body 1 . A compressor generally includes a crankshaft, a piston, a cylinder, an upper bearing and a lower bearing, the cylinder is arranged between the upper bearing and the lower bearing, the piston is arranged in the compression chamber 2 of the cylinder, and the crankshaft is passed through the upper bearing and the lower bearing to drive the piston to rotate , the motor drives the crankshaft to ro...

Embodiment 3

[0076] like Figure 10 As shown, the difference between the present embodiment and the second embodiment is that the heat insulation cavity 6 is a closed heat insulation cavity. Specifically, a semi-circular cavity with one end open and the other end closed can be milled on the cylinder body 1 first. Close the hollow body.

[0077] The rest of this embodiment is the same as that of Embodiment 2, and the features not explained in this embodiment are all explained in Embodiment 1, and will not be repeated here.

Abstract

The invention relates to the field of compressor technical equipment, in particular to a thermal insulation and noise reduction cylinder of a compressor. The cylinder comprises a cylinder body which is provided with a compression cavity, a gas inlet hole communicated with the compression cavity, a slide piece groove communicated with the compression cavity. The cylinder further comprises a thermal insulation and noise reduction piece which is used for slowing down heat exchange between the compression cavity and the outside world and is arranged on the cylinder body. According to the cylinder, the compression cavity of the cylinder of the compressor is isolated through the thermal insulation and noise reduction piece, heat exchange between the compression cavity and a shell of the compressor is avoided, and therefore heat in the high-temperature area in the shell of the compressor is effectively prevented from penetrating through the cylinder body to be transmitted to the compression cavity, it is also avoided that heat of a high-temperature cavity is transmitted into the shell of the compressor, it is avoided that refrigerant is heated and expanded before being compressed by a piston, and the overall performance of the compressor is improved. The thermal insulation and noise reduction piece can effectively prevent noise in the compression cavity from being transmitted outwards, and noise of the compressor is reduced.

Description

technical field [0001] The invention relates to the field of compressor technical equipment, in particular to a heat-insulating and sound-absorbing cylinder for a compressor. Background technique [0002] Compressor, a fluid machine that elevates low-pressure fluid to high-pressure fluid, is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant to the exhaust pipe to provide power for the refrigeration cycle, thereby realizing compression, condensation, heat release, expansion, evaporation and absorption. Hot refrigeration cycle. The compression ratio refers to the ratio of the absolute pressure of the exhaust gas to the absolute pressure of the intake air in the compression cylinder. [0003] In the compressor, the compressor cylinder is the main part of the compressor pump body. ...
