Abstract

The utility model belongs to the field of design of centrifugal compressors for natural gas in the west-east national gas transmission project, and particularly relates to a vertical dividing centrifugal compressor with a horizontal air inlet cylinder and a horizontal air outlet cylinder. The vertical dividing centrifugal compressor comprises a compressor shell, separating plates, an end cover, supporting bearings, a main shaft, impellers, separating sleeves, a balanced disc, the air inlet cylinder and the air outlet cylinder, wherein the two ends of the compressor shell are connected with the end cover through end cover connecting devices, the main shaft is arranged in the compressor shell, the two ends of the main shaft are in rotation connection with the end cover through the supporting bearings, the main shaft is sleeved with the impellers in all stages, the separating sleeves are arranged between the impellers in all stages, the main shaft is sleeved with the balanced disc, and the balanced disc is connected with the impeller in the final stage in an abutting-against mode; the separating plates arranged between the impellers in all stages are connected to the inner wall of the compressor shell, the connecting positions between the separating plates and the impellers and the connecting positions between the separating plates and the separating sleeves are provided with port ring seals and inter-stage seals respectively, a balanced disc seal is arranged between the balanced disc and the outlet separating plate, and the air inlet cylinder and the air outlet cylinder are horizontally arranged on the two sides of the compressor shell. The vertical dividing centrifugal compressor can stably and efficiently pressurize the natural gas and enable the natural gas to be conveyed in a pipe.
