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

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...
