Abstract

The invention discloses a multistage hydraulically-driven hydrogen compressor control system and method.The multistage hydraulically-driven hydrogen compressor control system comprises compression oil cylinders which comprise a plurality of first-stage compression oil cylinders and a plurality of second-stage compression oil cylinders, and each first-stage compression oil cylinder and each second-stage compression oil cylinder are arranged in series through a gas pipeline; the air supply source independently supplies power to the first-stage compression oil cylinder and the second-stage compression oil cylinder; the plurality of first heat exchangers are respectively connected in series between the first-stage compression oil cylinder and the second-stage compression oil cylinder; a first-stage reversing valve and a first-stage compression overflow valve are further connected in series between each first-stage compression oil cylinder and the corresponding access port of the hydraulic station, and a second-stage reversing valve and a second-stage compression overflow valve are further connected in series between each second-stage compression oil cylinder and the corresponding access port of the hydraulic station; and the gas utilization equipment is connected to the tail end of the second-stage compression oil cylinder. The displacement of the compressor is dynamically adjusted according to actual working condition requirements so as to adapt to various different working conditions, the operation efficiency of the hydraulic drive compressor is improved, and stable operation of hydrogenation facilities is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydrogen compressors, in particular to a multi-stage hydraulically driven hydrogen compressor control system and method. Background technique [0002] In the existing hydrogen refueling station applications, the gas compressors are mostly conventional hydraulic drives, and are generally single-stage compression or single-cylinder two-stage compression. Under the condition of constant external conditions, the compressor displacement is fixed, and the compression During the working process of the machine, the displacement of the compressor is passively changed according to the intake pressure of the compressor. Since hydrogen long-tube trailers are generally used as the source to supply gas to the station in the hydrogen refueling station, the intake pressure is a dynamic change. When filling the vehicle, the hydrogen flow into the fuel cell vehicle needs to be adjusted to prevent over-temperature during th...
