The technological scheme of the utility model:
A kind of hydraulic compressed natural gas vehicle gasification device; Form by hydraulic type gas cylinder, hydraulic pressure installation, high-pressure gas-liquid separator, high-pressure gas cylinder group and filling machine; The upper end gas port of hydraulic type gas cylinder is connected with natural air-air source through pipeline and is provided with gas source inlet valve and one-way valve a; The lower end liquid mouth of hydraulic type gas cylinder is connected with the fluid pipeline of hydraulic pressure installation through pipeline; The upper end gas port of hydraulic type gas cylinder is connected in series through pipeline and high-pressure gas-liquid separator and high-pressure gas cylinder group; On the pipeline between hydraulic type gas cylinder and the high-pressure gas-liquid separator, be provided with one-way valve, on the pipeline between high-pressure gas-liquid separator and the high-pressure gas cylinder group, be provided with control valve, pressure gauge a and safety valve; High-pressure gas-liquid separator is a gas cylinder, and compressed natural gas gets into from the gas cylinder bottom, and the gas cylinder top is located in the air outlet; The high-pressure gas cylinder group is the high-pressure gas cylinders of two groups of parallel connections and is used alternatingly that each bypass line is respectively equipped with inlet/outlet valve and pressure gauge b, and the high-pressure gas cylinder group is connected with filling machine through pipeline and is provided with the aerating outlet valve.
The working principle of the utility model:
This hydraulic natural gas automobile gas station utilizes hydraulic pressure installation that wear resistance hydraulic oil is directly injected the hydraulic type gas cylinder; Back and forth compressed natural gas is to 20Mpa; Deliver to then in the high-pressure gas cylinder group, inject high-pressure natural gas in the air cylinder of automobile through filling machine again and reach purpose to refueling.Carrying out along with refueling; Compressed natural gas pressure in the air cylinder descends; Hydraulic pressure installation continues compressed natural gas and in high-pressure gas cylinder, replenishes compressed natural gas; Need not adopt other supercharging equipment, promptly rock gas pressurizeed to substitute the compressor compresses rock gas, so not only reduce equipment investment but also can cut down the consumption of energy with hydraulic pressure installation.
The working procedure of the utility model:
This aerator can be earlier with the compressed natural gas that is full of 20Mpa in the high-pressure gas cylinder group, and the high-pressure gas cylinder component becomes two groups.When opening air gun to refueling, one group of gas cylinder begins air feed, opens the oil hydraulic pump compressed natural gas simultaneously and replenishes compressed natural gas to gas cylinder.Organize and continue aerating in the subsequent use gas cylinder when the pressure of rock gas in the hydraulic type gas cylinder and working pressure switch to another during near balance until arriving customer requirement.
The utility model has the advantages that: adopt hydraulic pressure installation to replace the compressor compresses rock gas, the gas cylinder group stores compressed natural gas, and simple in structure, little investment, maintenance cost be low, cut down the consumption of energy, adaptability is strong, has good economic benefit.
