Abstract

The invention provides a hydraulically-driven hydrogen compressor, and relates to the field of compressors. The hydraulically-driven hydrogen compressor comprises a gas path and an oil path. The low-pressure hydrogen pipeline comprises a low-pressure hydrogen pipe orifice, a hydrogen pipeline ball valve, an air inlet pipeline pneumatic valve, a pre-compression cooler, a first-stage piston compression cylinder body, a first-stage cooling assembly, a second-stage piston compression cylinder body, a second-stage cooling assembly, an exhaust pipeline pneumatic valve and an exhaust pipe orifice which are sequentially connected in series; the oil way comprises an oil tank, a motor, an electric pump set and a three-valve set. The motor is connected with the electric pump set; an oil inlet of the electric pump set is communicated with the oil tank, and an oil outlet of the electric pump set is communicated with oil inlets of the first-stage piston compression cylinder body and the second-stage piston compression cylinder body through the three-valve set. Oil outlets of the first-stage piston compression cylinder body and the second-stage piston compression cylinder body are respectively communicated with an oil tank through a three-valve group; the technical problem that the service life of an existing electrically-driven hydrogen compressor is shortened due to frequent starting and stopping can be solved, and the hydrogen output pressure is stable.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a hydraulically driven hydrogen compressor. Background technique [0002] Nowadays, compressors are the key equipment for hydrogen boosting in hydrogenation stations, and the reliability of their equipment performance directly determines the overall operational reliability of hydrogenation stations. At present, traditional diaphragm compressors are mostly used in hydrogenation stations. [0003] The diaphragm compressor in the hydrogen refueling station is selected according to the design conditions such as the daily hydrogen refueling capacity of the hydrogen refueling station, the number of vehicles, and the filling amount of a single vehicle. Therefore, during the period of fluctuating hydrogen use, the electric drive compressor Frequent start and stop are required to adjust the output power, and frequent start and stop will greatly affect the service life of the electric drive comp...
