Abstract

The invention provides a quick start and stop system of a hydrogen compressor. The oil delivery pipe is connected to the oil port A of the compression cylinder of the hydrogen compressor through the oil passage A of the hydraulic pump, the one-way valve and the hydraulic slide valve; the oil port of the compression cylinder of the hydrogen compressor is B returns to the fuel tank through the oil pipeline, the oil circuit B of the hydraulic slide valve, the fuel tank heat exchanger, and the hydraulic oil filter; it also includes a quick start branch circuit, which includes an electromagnetic unloading valve and an overflow valve; One way behind the hydraulic pump is connected to the oil port of the compression cylinder through a one-way valve and a hydraulic slide valve, and the other way is returned to the oil tank through an overflow valve and an electromagnetic unloading valve. Before starting the hydrogen compressor, open the electromagnetic unloading valve and overflow valve to make the hydraulic pump in the no-load state, and start the motor driving the hydraulic pump; after the motor is started, close the electromagnetic unloading valve and overflow valve to make the hydraulic pump Enter booster mode, start the hydrogen compressor, so that the hydrogen compressor can achieve the purpose of quick start.

Description

technical field [0001] The invention relates to a system for quickly starting a hydrogen compressor in a hydrogen refueling station in a shutdown state and quickly stopping it in a running state. Background technique [0002] As an emerging vehicle fuel, hydrogen has the advantages of low air pollution, high thermal efficiency, abundant sources, and economy. In order to solve the air pollution caused by traditional fuel vehicles, the country has vigorously developed hydrogen fuel cell vehicles in recent years. In order to solve the problem of battery life of hydrogen fuel cell vehicles, the country has plans to build hydrogen refueling stations in various places. [0003] A hydrogen refueling station is a gas station that provides hydrogen to hydrogen fuel cell vehicles. At present, the hydrogen supplied by domestic hydrogen refueling stations is mainly high-pressure hydrogen. The hydrogen comes from external hydrogen supply (transported to the hydrogen refueling station by...
