Abstract

The invention discloses a mechanical piston compressor for a hydrogen refueling station. The compressor comprises a cylinder which is vertically arranged and is provided with at least two cylinder bodies that are arranged in parallel, a shell and a guide mechanism. A piston rod is arranged in each cylinder body, and a piston is arranged on each piston rod; the interior of the shell is hollow; theguide mechanism is arranged in the shell, a plurality of guide channels are formed in the guide mechanism, and each guide channel corresponds to one cylinder body so that the piston rods of the cylinder bodies can pass through the guide channels when moving up and down, and the piston rods can be limited, guided and sealed; and the technical difficulties of oil-free lubrication and dynamic sealingin high-pressure and hydrogen environments are solved, and safe and reliable long-time operation of the compressor in the hydrogen refueling station is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical piston compressors for hydrogen refueling stations. More specifically, the present invention relates to a mechanical piston compressor for a hydrogen refueling station that can meet high pressure and hydrogen environments, and is oil-free and well-sealed. Background technique [0002] The hydrogen refueling station is a key hub connecting the upstream hydrogen production of the hydrogen energy industry and the downstream fuel cell vehicle hydrogen use, and the hydrogen compressor is the core equipment of the hydrogen refueling station. In order to ensure the purity and compression displacement of hydrogen, the hydrogen compressors currently used in domestic hydrogen refueling stations include metal diaphragm compressors and hydraulic piston compressors. [0003] Because the traditional mechanical piston compressor cannot overcome technical difficulties such as oil-free lubrication and dynamic sealing, i...
