Problems solved by technology

[0002] The chlorine compressor is a centrifugal compressor, and the seal between the input shaft and the body is particularly important. If leakage occurs during use, the entire compressor must be disassembled for overhaul, resulting in the need to replace the dry gas seal and other parts of the body. , which not only increases the maintenance cost, but also wastes a lot of manpower, and the maintenance efficiency is low

Abstract

The invention relates to a compressor input shaft sealing structure. The compressor input shaft sealing structure comprises a compressor body and an input shaft. The input shaft is mounted on one side of the compressor body, and a shaft sleeve is coaxially mounted between the input shaft and the compressor body in a sealed manner. The upper end face and the lower end face of the shaft sleeve are each provided with an annular groove for containing a sealing ring. According to the compressor input shaft sealing structure, the shaft sleeve and the sealing ring are used in cooperation, and the sealing effect of the input shaft is effectively improved; and the leakage problem of the input shaft is solved. The compressor input shaft sealing structure is simple in structure, and scientific and reasonable in design; dry gas seals and other partial parts of the compressor body are not required to be replaced, and maintenance cost is reduced; and manpower is saved, and the maintenance efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a compressor input shaft sealing structure. Background technique [0002] The chlorine compressor is a centrifugal compressor, and the seal between the input shaft and the body is particularly important. If leakage occurs during use, the entire compressor must be disassembled for overhaul, resulting in the need to replace the dry gas seal and other parts of the body. , This not only increases the maintenance cost, but also wastes a lot of manpower, and the maintenance efficiency is low. [0003] After searching, I found a document related to the content of this patent application, the Chinese invention patent with the publication number CN2811619, which discloses a hermetic compressor, which includes: an airtight container, an electric motor installed in the airtight container, The compression mechanism arranged in the airtight container and driven by the motor, the lubricat...
