Description
Technical field:
The present invention relates to automobile with compressed natural gas air entraining substation technical field, especially a kind of secondary gas filling station self-complementing voltage-stabilizing charging method and device.
Background technology:
By standard GB 50156--2002 (version in 2006) " automobile fuel filler gas station design and construction standard " regulation, the compression natural gas air entraining substation can use gas cylinder group or gas well that the high, medium and low three group gas storages of volume ratio as 1:2:3 are set.The volume minimum of high pressure air reservoir only is 1/6 of a substation air reservoir capacity, but can its pressure have determined the external gas filed top pressure of air entraining substation reach the rated pressure scope.So when the fortune tank car was supplied gas to air entraining substation, the substation compressor all was that the sequence control according to high, medium and low voltage puts on the air to the substation gas storage, at first make the high-pressure gas storehouse reach behind the authorized pressure it, and then centering, low gas storage inflation.
But after the fortune tank car leaves, do not have under the state of external air source, though the substation compressor is housed, account for substation gas storage total volume 5/6 in, low pressure gas storage can't add to the high-pressure gas storehouse.When air entraining substation continued additional gas, high-pressure gas storehouse pressure still constantly descended, and externally can't keep the rated pressure scope, influences the air entraining substation normal operation.
Summary of the invention:
The objective of the invention is to overcome the deficiency of existing air entraining substation technology and device, a kind of secondary gas filling station self-complementing voltage-stabilizing charging method and device are provided.The object of the present invention is achieved like this: secondary gas filling station self-complementing voltage-stabilizing charging method is exactly under the state that does not have the outer source of the gas in station, utilizes low, the middle pressure gas storage of having by oneself in the station to be followed successively by the high-pressure gas storehouse and does additionally, makes the pressure to additional gas remain on rated range.Its device is mainly by the substation compressor, and the high, medium and low voltage gas storage refills road system and filling machine certainly and is formed by connecting.
The substation compressor is equipped with sequence control dish and overvoltage stoppage protection device, and exhaust gas pressure is 20-25MP
aFreeing pipe is the high, medium and low voltage gas supply electromagnetic valve by the sequence control dish respectively, the high, medium and low voltage gas supply line that connects high, medium and low voltage gas storage and filling machine, air inlet pipe connects check valve, pressure transformer and external interface successively, pressure transformer sends signal during outer source of the gas at station not, makes oneself refill road system self-opening; The high, medium and low voltage gas storage is equipped with pressure transformer respectively, low, middle pressure gas storage connects the substation compressor inleting pipe by low, the middle hydraulic circuit electromagnetic valve that refills the road system certainly respectively, outside having the station, under the state of source of the gas, do not mend the air reservoir of voltage stabilizing aerating certainly as air entraining substation successively; From refilling the road system by the pressure transformer that is contained in respectively on the high, medium and low voltage gas storage, in in being connected on respectively, between low pressure gas storage and the substation compressor inleting pipe, the low tension loop electromagnetic valve, connect to form with the electric control panel of benefit certainly with the interlock of sequence control dish, the interlock circuit of the signal of circuit electromagnetic valve and pressure transformer and sequence control dish all inserts from mending electric control panel, link successively during operation with the gas supply electromagnetic valve of low, middle pressure gas storage close, the circuit electromagnetic opening of valves, switch pressure can be adjusted; Whole device can adopt the module assembling; When gas storage many groups in substation are provided with, while corresponding pressure boost transmitter and circuit electromagnetic valve in refilling the road system certainly.
Air entraining substation is before mending the voltage stabilizing gas filled device and bringing into use, and the high, medium and low voltage gas storage of substation should be inflated in advance, and the air pressure in high-pressure gas storehouse should reach rated pressure 20-25MP
a, filling machine is externally inflated to be reached rated range.
When air entraining substation from mending voltage stabilizing gas filled device external interface not during the outer source of the gas connection in station, pressure transformer sends signal from mending the electric control panel self-opening, the low tension loop electromagnetic valve that connects the compressor inleting pipe line is open-minded, the interlock of the dish of sequence control simultaneously, close the inflation electromagnetic valve of low pressure gas storage, start the substation compressor.Do source of the gas with low pressure gas storage own in standing this moment, for the high-pressure gas storehouse replenishes gas, makes high-pressure gas storehouse pressure continue to remain on the rated pressure scope through the substation compressor, continues additional gas for filling machine.
When low pressure gas storage hypotony can't be utilized, the pressure voltage transformer sent signal, mended the interlock of electric control panel and sequence control dish certainly, closed the inflation electromagnetic valve of low tension loop electromagnetic valve and middle pressure gas storage, hydraulic circuit electromagnetic valve in opening.Do source of the gas with middle pressure gas storage own in standing this moment, for the high-pressure gas storehouse replenishes gas, makes high-pressure gas storehouse pressure continue to remain on the rated pressure scope through the substation compressor, continues additional gas for filling machine.Until the external air source supply is arranged.
Secondary gas filling station self-complementing voltage-stabilizing charging method and device replenish external air source and keep the specified device that adds atmospheric pressure and compare with existing only depending on, only increase few parts and can improve the station equipment degree of utilization, prolong the work-hours that air entraining substation keeps rated pressure, extend the distance of offering between the mothers and sons station, that improves the fortune tank car unloads gas efficient, save power consumption, reduce operating cost.Simple in structure, simple installation, automatic operating, convenient and reliable.Can effectively improve gas taking rate when using skid gas cylinder group, improve fortune efficient.
