Embodiment Construction

[0025] The present invention will be described in detail below with reference to the figures and examples.

[0026] As shown in Figures 1 and 3, a motor 4 is installed inside the airtight container 1, and a crankshaft 5 is pressed and fixed in the center of the rotor 2, and a rolling piston 7 is inserted into the lower end and outside of the eccentric part 6 of the crankshaft 5 to form a cylinder. 9. A compression space 8 where the inner rolling piston 7 compresses the refrigerant gas, and a compression mechanism 12 composed of upper and lower bearings 10 and 11.

[0027] A gas-liquid separator 17 is provided on the side of the suction port 9a of the cylinder 9 to prevent the inflow of liquid refrigerant, and a discharge pipe 18 is provided on the top of the sealed container 1 to discharge the high-pressure refrigerant gas compressed by the compression mechanism 12 to the outside.

[0028] In such a hermetic rotary compressor, the gas suction connection device according to the...

Abstract

The present invention discloses gas sucking pipe connecting unit of sealed rotary compressor, and belongs to the field of compressor structure. The present invention includes pressing annular inlet pipe into the inlet of the cylinder, pressing the outside of the inlet pipe into outside of the sucking pipe and welding the inside of the canal of liquid storage to the outside of the inlet pipe. The present invention can prevent the surface of the cylinder and the rotor inside the compressor from becoming uneven during the welding and ensure the smooth running of the compressor. Said method can minimize the thermal deformation during welding. Therefore, the present invention can raise the performance and quality of sealed rotary compressor.

Description

technical field [0001] The present invention relates to the construction of compressors, in particular to gas suction connections for hermetic rotary compressors. Background technique [0002] In the existing fully enclosed compressor, as shown in Figure 1, a motor 4 composed of a rotor 2 and a stator 3 is arranged inside a sealed container 1, and a crankshaft 5 is pressed and fixed in a shaft hole 2a formed in the center of the rotor 2 in a vertical direction. . [0003] A compression mechanism 12 is provided at the lower end of the crankshaft 5 . And the compression mechanism is integrated with 6. The outer side of the eccentric part 6 is inserted into the rolling piston 7 . And the compression mechanism forms the rolling piston 7 to operate, and the compression space 8 for compressing the refrigerant gas is formed by the cylinder 9 and the upper and lower bearings 10,11. [0004] A valve plate 15 is provided on the outlet side of the discharge hole 10a on the upper be...
