Description
(1) technical field
The present invention relates to a kind of natural gas vehicle refueling device, particularly a kind of hydraulic compressed natural gas automobile air-entrapping device.
(2) background technique
Gas in natural gas line generally first passes through purified treatment, remove sulfur and moisture content in gas, then by compressor, pressure be compressed to 20Mpa by 0.1Mpa-2.0Mpa, at last by filling machine to the vehicle aerating.This device has following shortcoming: the first system bulky complex, and pipe-line system, control system except routine also need cooling system, spray system etc., the manufacture cycle is long, and early investment is large; The second maintenance cost is high, and energy consumption is high.
(3) summary of the invention
The objective of the invention is for above-mentioned existing problems, provide a kind of simple in structure, easy to use, energy consumption is low, the little hydraulic compressed natural gas automobile air-entrapping device of investment.
Technological scheme of the present invention:
a kind of hydraulic compressed natural gas automobile air-entrapping device, by the hydraulic high-pressure gas cylinder, hydraulic pressure installation, high-pressure gas-liquid separator, high-pressure gas cylinder group and filling machine form, the upper end gas port of hydraulic high-pressure gas cylinder is connected with natural air-air source by pipeline and is provided with gas source inlet valve and one-way valve a, the lower end liquid mouth of hydraulic high-pressure gas cylinder is connected with the fluid pipeline of hydraulic pressure installation by pipeline, the upper end gas port of hydraulic high-pressure gas cylinder is connected in series by pipeline and high-pressure gas-liquid separator and high-pressure gas cylinder group, be provided with one-way valve on the pipeline between hydraulic high-pressure gas cylinder and high-pressure gas-liquid separator, be provided with control valve on the pipeline between high-pressure gas-liquid separator and high-pressure gas cylinder group, pressure gauge a and safety valve, high-pressure gas-liquid separator is gas cylinder, and compressed natural gas enters from 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 cylinder of two groups of parallel connections and is used alternatingly, and 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 by pipeline and is provided with the aerating outlet valve.
Working principle of the present invention:
This hydraulic natural gas automobile gas station utilizes hydraulic pressure installation with in the direct injection liquid pressure type of wear resistance hydraulic oil gas cylinder, back and forth compressed natural gas is to 20Mpa, then deliver in the high-pressure gas cylinder group, then by filling machine, high-pressure natural gas is injected the purpose that reaches in the air cylinder of automobile to refueling.Carrying out along with refueling, compressed natural gas pressure drop in air cylinder, hydraulic pressure installation continues compressed natural gas and replenish compressed natural gas in high-pressure gas cylinder, do not need to adopt other supercharging equipment, namely with hydraulic pressure installation, rock gas is pressurizeed to substitute the compressor compresses rock gas, so not only reduced equipment investment but also can reduce energy consumption.
Working procedure of the present invention:
This aerator can first will be full of the compressed natural gas of 20Mpa in the high-pressure gas cylinder group, the high-pressure gas cylinder component becomes two groups.When opening air gun to refueling, one group of gas cylinder begins air feed, opens simultaneously the oil hydraulic pump compressed natural gas and replenishes compressed natural gas to gas cylinder.Switch in the standby gas cylinder of another group during near balance when the pressure of rock gas in the hydraulic high-pressure gas cylinder and working pressure and continue aerating until arrive customer requirement.
Advantage of the present invention is: 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, reduce energy consumption, strong adaptability, has good economic benefit.
