The specific embodiment
Accompanying drawing shows the most preferred embodiment of Intelligentized air dryer of the present invention.As shown in the figure, the drying assembly of described air dryer is installed on the base assembly that is mated.Have the drier 1 of suction usefulness and the filter 2 of the dustproof usefulness of oil suction in the air drying cylinder assembly, its middle filtrator 2 places the bottom and the outside of drying assembly, and drier 1 places the top and the inboard of drying assembly.There is circular passage H to connect between filter 2 and the drier 1.Air-in 20 connects the air compressor (not shown).Pressure reading device 3 directly reads on the mouth 25 with the pressure of thread connection at drier valve body 5, and it reads air constantly and exports suitable for reading 21 air pressure, and converts the drier output pressure signal that reads to voltage signal and feed back to ECU master control device 8.The both positive and negative polarity of pressure reading device 3, automatically controlled actuating unit 15 and ECU master control device 8 is all in parallel with the both positive and negative polarity of heater 7.The action of automatically controlled actuating unit 15 is by 8 controls of ECU master control device.ECU master control device 8 joint covers 11, gland 14 usefulness screws tightly connect whole automatically controlled actuating unit 15 and ECU master control device 8 with drier valve body 5.Valve 10 and 12 in the automatically controlled actuating unit 15 can be controlled switching by its corresponding magnetic valve 9 and 13.
Illustrate the course of work of diagram most preferred embodiment below.
Behind vehicle launch or in normal the enforcement, enter the inlet chamber A of drier by air-in 20 from the compressed air of air compressor output.Because compressed air descends to some extent in temperature when being connected to the copper pipe (not shown) of input port, can form condensed water in drier A chamber, and arrive on the air bleeding valve G by drain outlet B.Meanwhile, behind air process filter 2, be mixed in airborne mist of oil and impurity and be filtered.Air flows to drying upper end I through circular passage H, enters subsequently in the drier 1 and filters moisture.In air was flowed through the process of drier 1, the upper strata of drier 1 is taken off and be trapped in to moisture.Air after dry the processing backs down output check valve 4 and exports the suitable for reading 21 four-loop protection valve (not shown)s that connect from the last output channel F flow direction and air; Meanwhile, dry air enters down the 5L regeneration gas receiver 16 that output channel E flows to and air output end opening 22 connects through the hole of damming.
When air compressor during to main air reservoir gas storage, the pressure reading device 3 that is bound up on drier valve body 5 converts detected output pressure to voltage signal and feeds back to ECU master control device 8, after ECU master control device 8 obtains the feedback information of pressure reading device 3, control air inlet magnetic valve 13, the exhaust solenoid valve 9 of automatically controlled actuating unit 15 by logical program and do with air intake valve 12, drain tap 10 and combine and separating action.Thereby can enter the mouth from regeneration air from the clean recoil air pressure of 5L regeneration gas receiver 16 and 24 to enter into discharge chamber D through regeneration inlet channel C, promote exhaust pition 6 downwards and open exhaust valve port G, finally make most of regeneration air from output channel E backflow down, realize the regeneration of drier 1 and filter 2; After exhaust valve port G opened a period of time, ECU master control device 8 can be arranged the air pressure that promotes exhaust pition 6 to atmosphere from regeneration exhaust duct J, moves and close exhaust valve port G on the exhaust pition 6, realizes the air feed again to main air reservoir.The driver not under the prerequisite of closing automobile circuit, if when ECU master control device 8 does not receive the feedback signal of pressure reading device 3, perhaps the electric-control system circuit of drier be short-circuited, when opening circuit, its warning system 18 will be sent alarm signal to driver's cabin.
During cold weather, hindered the exhaust pition action if there is hydrops to freeze in the exhaust apparatus, heater 7 will be connected the external power supply 17 of a rated output voltage 24V, rated output power 100W, and the exhaust apparatus position is heated, and guarantee the reliability of this air dryer in Han Qu work.
Those skilled in the art are not difficult to find out, Intelligentized air dryer of the present invention is not only applicable to the moving system of Automobile air control, and its mentality of designing can be used as also that other belongs to the air dryer of air control equipment in the industrial production.
Abovely describe in detail in conjunction with the preferred embodiments of the present invention, but this is not a limitation of the present invention, every technical spirit according to the present invention program is to any simple modification that above embodiment did, and equivalent variations and modification all still belong in the present invention program's the scope.
