Abstract

The invention provides a quick start and stop system for a hydrogen compressor. The quick start and stop system is characterized in that an oil conveying pipe is connected with an oil port A of a compression cylinder in the hydrogen compressor through a hydraulic pump, a one-way valve and an oil path A of a hydraulic sliding valve; hydraulic oil returns to the oil tank from an oil port B of the compression cylinder in the hydrogen compressor through the oil conveying pipe, an oil path B of the hydraulic sliding valve, an oil tank heat exchanger and a hydraulic oil filter; the quick start and stop system further comprises a quick start branch; the quick start branch comprises an electromagnetic unloading valve and an overflow valve; and after the oil conveying pipe passes through the hydraulic pump, one path of the oil conveying pipe is connected with the corresponding oil port through the one-way valve, the hydraulic sliding valve and the compression cylinder, and the hydraulic oil returns to the oil tank from the other path through the overflow valve and the electromagnetic unloading valve. Before the hydrogen compressor is started, the electromagnetic unloading valve and the overflow valve are opened, the hydraulic pump remains in the no-load state, and a motor used for driving the hydraulic pump is started; after the start of the motor is completed, the electromagnetic unloading valve and the overflow valve are closed, the hydraulic pump enters the supercharging mode, and the hydrogen compressor is started; and accordingly, the purpose of quickly starting the hydrogen compressor is fulfilled.

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...
