Abstract

The invention discloses an efficient and energy-saving type large-discharge double-line hydraulic gas substation system and belongs to the technical field of compressed natural gas filling. The system comprises a hydraulic substation CNG (Compressed Natural Gas) transport trailer, a hydraulic supercharging pry body, an electric control system and a gas filling machine, wherein the hydraulic substation CNG transport trailer is respectively connected with a hydraulic oil way quick coupler, an exhaust gas circuit quick coupler and a jacking block body quick coupler on an operating platform of the hydraulic supercharging pry body, the exhaust pipeline of the hydraulic supercharging pry body is connected to the gas filling machine, and the electric control system is respectively connected with the hydraulic substation CNG transport trailer and a control module of the hydraulic supercharging pry body. The efficient and energy-saving type large-discharge double-line hydraulic gas substation system has the advantages of high efficiency, energy saving, large gas filling capability and stable operation, and the system can be used for realizing stepless regulation of a large range of 1700-4080 m<3>/h and is compatible to the deflation function of hydraulic substation CNG transport trailers of 8 tube 559 series and 6 tube 711 series.

Description

technical field [0001] The invention belongs to the technical field of compressed natural gas (CNG) refueling, and in particular relates to a high-efficiency, energy-saving and large-displacement double-line hydraulic refueling substation system. The invention is not only compatible with the unloading function of the 8-pipe 559 series and 6-pipe 711 series hydraulic sub-station CNG transport trailers, but also has high gas filling capacity and efficiency, low energy consumption, stable system operation and long service life of the hydraulic pump Etc. Background technique [0002] At present, the displacement (filling capacity) of the existing natural gas hydraulic filling sub-station mainly has two types: 1000Nm3 / h and 2000Nm3 / h, equipped with a gas storage cylinder with a diameter of 559mm and a maximum nominal volume of 18m 3 , the 8-pipe hydraulic sub-station CNG transport trailer with a maximum natural gas transportation volume of 4551Nm3 (the CNG storage and transporta...
