Abstract

The invention relates to the field of compression equipment and discloses an air suction pipe set, a compressor and a mounting method of the air suction pipe set of the compressor. The air suction pipe set is used for connecting a liquid storage device of the compressor with a compression unit located in a main shell of the compressor. The air suction pipe set comprises a connecting pipe and a heat insulating pipe. The connecting pipe comprises a first pipe section used for being connected with the liquid storage device and a second pipe section used for being connected with the main shell ina welded mode. The heat insulating pipe communicates with the compression unit, at least part of the heat insulating pipe is sleeved with the connecting pipe, the heat insulating pipe is in contact connection with the inner wall face of the first pipe section, and the heat insulating pipe and the second pipe section are arranged in a spaced mode in the radial direction. The heat insulating pipe isin contact connection with the inner wall face of the first pipe section, and the heat insulating pipe and the second pipe section are arranged in the spaced mode in the radial direction so as to form a heat insulating chamber, so that heat transmitted to the heat insulating pipe is reduced, and the heat insulating effect is ideal; and meanwhile, the number of parts included in the air suction pipe set is small, the structure is simple, the number of weld joints is small, thus the risk of airtightness leakage is reduced, and the using property of the air suction pipe set is improved advantageously.

Description

technical field [0001] The invention relates to the field of compression equipment, in particular to a suction pipe group, a compressor and a method for installing the suction pipe group of the compressor. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. A compressor generally includes a liquid accumulator, a main housing, a compression unit (such as a cylinder) disposed in the main housing, and a suction pipe group connecting the liquid accumulator and the compression unit. During the refrigeration cycle, the main casing of the compressor contains high-temperature and high-pressure gas, and the suction pipe group is always sealed to connect the liquid receiver and the compression unit, so that the heat in the main casing is easily transferred to the suction pipe through the outer wall of the suction pipe group. The low-temperature gaseous refrigerant flowi...
