Abstract

The invention discloses an end cover structure for preventing working gas leakage of a vertically split compressor, comprising an end cover main body, an air inlet hole, a connecting hole and a dry gas sealing hole arranged on the end cover main body, the air inlet The hole communicates with one end of the connecting hole, the other end of the connecting hole communicates with the dry gas sealing hole, and the dry gas sealing hole communicates with the dry gas sealing area. The invention also discloses a processing method of the end cover structure preventing the leakage of the working gas of the vertically split compressor, and a compressor including the end cover structure preventing the leakage of the working gas of the vertically split compressor. The end cover structure for preventing the leakage of the working gas of the vertically split compressor and the processing method thereof provided by the present invention can prevent the working medium in the compressor from leaking from the connecting hole of the end cover structure for preventing the leakage of the working gas of the vertically split compressor , and the end cover structure that prevents the leakage of the working gas of the vertically split compressor has high processing efficiency and low processing cost.

Description

technical field [0001] The invention relates to the technical field of centrifugal compressors, in particular to a compressor, an end cover structure for preventing leakage of working gas of a vertically split compressor, and a processing method thereof. Background technique [0002] A centrifugal compressor is a blade-rotating machine. In the centrifugal compressor, the gas runs along the radial direction perpendicular to the compressor shaft, and the increase of the gas pressure is achieved by the interaction between the blade and the gas. [0003] Centrifugal compressors play an important role in the national economy. Especially in metallurgy, petrochemical, natural gas transmission, refrigeration and power and other industrial sectors have been widely used. [0004] The vertical split compressor is a kind of centrifugal compressor, which is composed of end cover, casing, partition, rotor, seal and other parts, and can compress gas with high pressure. The end cover is ...
