Abstract

The invention relates to the field of liquid-driven compressors, and provides a liquid-driven compressor and a supercharging method thereof. The compressor comprises an electric pump set, a hydrogen input unit, a liquid-driven hydrogen booster pump, a diffusion unit, a hydrogen conveying unit and a hydrogenation gun connecting unit; and one end of the liquid-driven hydrogen booster pump is connected with the electric pump set, the other end of the liquid-driven hydrogen booster pump is connected with the hydrogen input unit and the hydrogen conveying unit, and the hydrogen conveying unit is connected with the diffusing unit and the hydrogenation gun connecting unit. The compressor is driven through liquid oil, the influence on the service life of the compressor during starting and stopping of the compressor is reduced, and the compressor is more stable when outputting compressed hydrogen.

Description

technical field [0001] The invention relates to the field of liquid-driven compressors, in particular to a liquid-driven compressor and a boosting method thereof. Background technique [0002] The compressor in the hydrogen refueling station is the key equipment of the hydrogen refueling station. The reliability of its equipment performance directly determines the overall operation reliability of the hydrogen refueling station. At present, the traditional electric drive compressor is mostly used in the hydrogen refueling station. [0003] The electric drive compressor in the hydrogen refueling station is selected according to the design conditions of the hydrogen refueling station, such as the daily hydrogen refueling capacity, the number of vehicles, and the filling volume of each vehicle. Therefore, the electric drive compressor Frequent starts and stops are required to adjust the output power, and frequent starts and stops will greatly affect the service life of the elect...
