The operation principle of electronic type sequential control dish of the present invention is as follows: after compressor apparatus energising, and CPU commands magnetic valve SV3 to open, and instrument supply gas controls Pneumatic valve MVA3-1, MVA3-2, MVA3-3 by magnetic valve SV3 and opens simultaneously.
1, first the cooled gas of compressor pressurizes enter high-pressure gas cylinder group air inlet pipeline and gas selling machine high pressure aspirating pipeline through the manual ball valve MV of main air inlet pipeline, check valve CV0.If do not have pressure in high-pressure gas cylinder group, and aerating vehicle is had to need aerating (now gas selling machine high pressure valve is opened).Natural gas now after pressurization is by the restriction of sequence valve SRVV force value 24Mpa and check valve CV3, and gas according to the sequential flowing of MV-CV0-CV2-MVA3-1, can only enter gas selling machine, preferential to the aerating of aerating vehicle.
2, the cooled gas of compressor pressurizes enters high-pressure gas cylinder group air inlet pipeline and gas selling machine high pressure aspirating pipeline through the manual ball valve MV of main air inlet pipeline, check valve CV0.If there is no pressure in high-pressure gas cylinder group, do not need again to the aerating of aerating vehicle (now gas selling machine high pressure valve is closed).Natural gas now after pressurization is subject to the restriction of gas selling machine and check valve CV3, and gaseous-pressure supercharging, during more than 24Mpa, sequence valve SRVV opens, and gas enters high-pressure gas cylinder group through check valve CV1.Fuel gas flow order is: MV-CV0-SRVV-CV1-high-pressure gas cylinder group.
3, CPU is when pressure sensor PT1 receives high-pressure gas cylinder group pressure to 24Mpa, and commander's magnetic valve SV1 opens, and instrument supply gas controls Pneumatic valve MVA1 by magnetic valve SV1 and opens.At this moment high-pressure gas cylinder group air inlet pipeline and gas selling machine high pressure aspirating pipeline pressure are to 24Mpa, the Pneumatic valve MVA2 controlling low pressure gas bomb group air inlet pipeline and gas selling machine low pressure aspirating pipeline pressure does not open, and does not give again aerating vehicle aerating (now gas selling machine high pressure valve is closed).Gas according to the sequential flowing of MV-CV0-MVA1-CV4, can only enter middle pressure gas bomb group.
4, CPU is when pressure sensor PT2 receives middle pressure gas bomb group pressure to 24Mpa, and commander's magnetic valve SV2 opens, and instrument supply gas controls Pneumatic valve MVA2 by magnetic valve SV2 and opens.At this moment high-pressure gas cylinder group air inlet pipeline and gas selling machine high pressure aspirating pipeline pressure are to 24Mpa, and in middle pressure gas bomb group air inlet pipeline and gas selling machine, force feed air pipe pressure is also to 24Mpa, give again aerating vehicle aerating (now gas selling machine high pressure valve is closed).Gas according to the sequential flowing of MV-CV0-MVA2-CV5, can only enter low pressure gas bomb group.
5, when pressure sensor PT3 receives low pressure gas bomb group pressure to 24Mpa, do not give again aerating vehicle aerating (now gas selling machine high pressure valve is closed), sequence valve SRVV opens, high, medium and low voltage gas bomb group can fill simultaneously, until when reaching the setting value 25.4Mpa of compressor apparatus shutdown, compressor apparatus is shut down;
Inflation sequence is: MV-CV0-SRVV-CV1--high-pressure gas cylinder group
Gas bomb group is pressed in MV-CV0-MVA1-CV4-
MV-CV0-MVA2-CV5-low pressure gas bomb group.
6, in high, medium and low voltage gas bomb group, gas is full of, and compressor apparatus is shut down, and at this moment has aerating vehicle aerating (now gas selling machine high pressure valve is opened).First gas is got from low pressure gas bomb group, aerating vehicle is directly supplied through Pneumatic valve MVA3-3, when car bottle pressure and low pressure gas bomb group pressure comparatively close to and when not ensureing to fill speed, gas selling machine is switched to middle pressure gas bomb group, aerating vehicle is directly supplied through Pneumatic valve MVA3-2, when car bottle pressure and middle pressure gas bomb group pressure comparatively close to and when not ensureing to fill speed gas selling machine be switched to high-pressure gas cylinder group, through check valve CV3, Pneumatic valve MVA3-1 to aerating vehicle inflatable.
If 7 gas bomb groups do not reach requirement to aerating vehicle inflatable, compressor apparatus has been received machine signal and has been run, and sequential control dish can by 1 step to aerating vehicle inflatable, until fill it up with.
The inflation regime of electronic type sequential control dish of the present invention have employed compressor Priority Control Strategies.Electronic type sequential control dish is according to demand assignment throughput, and when needs are to aerating refueling, if caisson pressure is inadequate, electronic type sequential control dish directly to aerating refueling, instead of gives caisson aerating by compressor apparatus.Like this, caisson can give aerating refueling, and compressor apparatus also can give aerating refueling (now compressor apparatus is not to caisson aerating).In this scheme, concerning compressor, the priority of automobile is the highest, and caisson takes second place.If caisson gassy, after caisson fills it up with gas to aerating automobile, electronic type sequential control dish supplements the gas be added to from caisson aerating automobile to caisson by compressor apparatus.This inflation regime significantly increases the utilization ratio of caisson, and improve the aerating speed of aerating automobile, for very effective small-sized station (compressor and caisson do not need large investment) or the more uniform gas station of aerating power load distributing.
Electronic type sequential control dish have employed a kind of system being referred to as three grades of order aerating strategies to caisson.In such systems, caisson is divided into three unitary part be separated completely, adopts sequential inflation scheme to be added by CNG in three grades of caissons.Gas is got gas way to realize from the taking-up caisson by gas selling machine employing order.
Three grades of caissons of the present invention are divided into high-pressure gas cylinder group (finally exitting), middle pressure gas bomb group (the second venting), low pressure gas bomb group (exitting at first) according to the sequencing getting gas from device.When caisson is all full of, the pressure that three stage arrangements start most is all 3600psig (24.8MPa).The gas storage volume of three ranks preferably divides by 50%, 30%, 20%.
First gas selling machine gets gas to refueling from low pressure caisson, once pressure starts equal (be actually flow be reduced to a unacceptable level judge), the source of the gas of gas selling machine is just switched to middle pressure caisson by the control system in gas selling machine, then same by pressure reduction to automobile inflating, until flow constantly reduces, be then switched to high-pressure gas system.Finally, once high-pressure installation gas flow rate is out reduced to certain level, just start compressor directly to refueling, until fill it up with.
In this scheme, the volume of three groups of caissons can be equal, but certain collocation method also can be adopted to be divided into three groups that differ in size.Utilize gas storage volume for more effective, generally the volume fraction of three groups of containers is divided into low pressure 50%, middle pressure 30%, high pressure 20%.
By electronic type sequential control dish, we can utilize total gas storage volume of about 32%, far above the utilization rate of buffer system; In addition, aeration speed is also greatly improved, because when gas selling machine switches between three groups of storage tanks, automobile gas cylinder can obtain three fulminant high speed inflations.
In practical operation, the gas storage volume due to gas station will be far longer than the gas cylinder volume of automobile, and gas selling machine only needs to get gas from one group or two groups of storage tanks just can fill it up with an automobile.
The electronic type sequential control dish principle of three grades of gas storage systems is: first compressor apparatus gives the inflation of high-pressure gas device, and being then middle pressure, is finally low pressure.This guarantee can low-voltage and medium voltage device complete they in power add tolerance after, automobile can be filled it up with by high-pressure gas device.In fact, when needs aerating, the highest compressor priority gives automobile gas cylinder; After automobile is filled it up with and gas selling machine cuts off air-flow, compressor just supplements the tolerance taken away from caisson.
It should be pointed out that the above detailed description of the invention can make the invention of those skilled in the art's comprehend, but do not limit the present invention in any way creation.Therefore, although this description and embodiment have been described in detail to the invention, it will be appreciated by those skilled in the art that and still can modify to the invention or equivalent replacement; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the invention, it is all encompassed in the middle of the protection domain of the invention patent.
