Vertical compressor suitable for high-temperature gas media

Abstract

The invention relates to the technical field of compressor structures, in particular to a vertical compressor suitable for high-temperature gas media, and accordingly integral compressor cooling can be conveniently achieved. The vertical compressor comprises a crank case and an air cylinder. A crankshaft is connected with a piston rod through a connecting rod and a cross-shaped head structure. A communication first oil path is arranged in the crankshaft and the connecting rod. An inlet of the first oil path is connected with an oil pump. The cross-shaped head structure comprises a cross-shaped head body and a cross-shaped head pin arranged on the cross-shaped head body. A hollow cavity is formed in the cross-shaped head pin. A second oil path is arranged in the cross-shaped head body. The cross-shaped head pin is provided with a first oil hole communicating with the hollow cavity and the second oil path, and a second oil hole communicating with the hollow cavity and an outlet of the first oil path. Sealing covers are arranged at the two ends of the cross-shaped head pin, a third oil path communicating with the second oil path is arranged in the piston rod, and a hollow oil return pipe communicating with the third oil path is arranged in the middle of the piston rod. An oil inlet and an oil outlet are formed in the outer wall of a cylinder body of the air cylinder. An oil cooling channel communicating with the oil inlet and the oil outlet is arranged in the cylinder body of the air cylinder.

Description

technical field [0001] The invention relates to the technical field of compressor structure, in particular to a vertical compressor suitable for high-temperature gas medium. Background technique [0002] Compressor is a driven fluid machine that upgrades low-pressure gas to high-pressure gas, and can be divided into piston compressors, screw compressors, centrifugal compressors, linear compressors, etc. Vertical piston compressor is a kind of compressor. The piston and crank are connected by crosshead and connecting rod. When the high-temperature (≤400℃) gas medium is compressed in the cylinder, it is necessary to install a suitable compressor on the compressor. Cooling mechanism, labyrinth compressors under normal working conditions are usually cooled by circulating water, that is, water cooling channels are installed on the cylinder block and crosshead slide to realize cooling of the cylinder block and crosshead, but under high temperature conditions, the cylinder cannot b...

Problems solved by technology

Vertical piston compressor is a kind of compressor. The piston and crank are connected by crosshead and connecting rod. When the high temperature (≤400℃) gas medium is compressed in the cylinder, it is necessary to install a suitable compressor on the compressor. Cooling mechanism, labyrinth compressors under normal working conditions are usually cooled by circulating water, that is, water cooling channels are set on the cylinder block and crosshead slide to realize cooling of the cylinder block and crosshead, but under high temperature conditions, the cylinder cannot be water cooled method, and the piston rod and the crosshead need to be cooled, the existing compressor structure cannot meet the cooling requirements
