Abstract

The invention provides a compressor pump body structure, a pump body assembly and a compressor. The compressor pump body structure comprises an air cylinder and a flange assembly arranged on the air cylinder, welding structures are arranged on the air cylinder and / or the flange assembly, each welding structure comprises a welding part and a separating part; welding points used for welding are formed on the welding part, a protruding structure is formed on the welding part, the protruding structure is formed by protruding towards the separating part, the welding points are located on the outerside of the welding part and are arranged opposite to the protruding structure; the separation part is located on the inner side of the welding part in the radial direction of the air cylinder and / orthe flange assembly, so that the welding part is separated from the main body part of the air cylinder and / or the flange assembly, and the influence of welding on the main body part of the air cylinder and / or the flange assembly is avoided; the plurality of welding structures are arranged in the circumferential direction of the air cylinder and / or the flange assembly. According to the compressor pump body structure, the pump body assembly and the compressor, welding stress and heat are absorbed through the welding structures, and the influence on the finish machining part of the pump body structure is avoided.

Description

Technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor pump body structure, a pump body assembly and a compressor. Background technique [0002] The rolling rotor compressor is a compressor that relies on the cylindrical rotor of the eccentric device to roll in the cylinder to realize the change of the cylinder working volume, and then realize the suction, compression and exhaust process. The conventional rolling rotor compressor is mainly composed of shell components, upper and lower covers, pump body components, motor components, and liquid distributor components. [0003] The casing component and the upper and lower covers cooperate to form a closed structure, and the pump body component is welded to the inside of the closed compressor casing through its flange or cylinder parts. The pump body components are composed of cylinders, rollers, crankshafts, upper and lower flange components (including upper and lower flanges...
