E loketse CAT Carter 2522237 lisebelisoa tsa excavator solenoid valve 252-2237 24V

Proportional solenoid valve

Kamoo e sebetsang kateng:

Likarolo tsohle tsa li-valve tsa solenoid ke coil ea motlakase ho latela karolo ea motlakase, ke hore, inductor.Ha inductor e fuoa lets'oao la motlakase, sebaka sa motlakase se hlahisoang ke hona joale se tla etsa hore "valve core" e tsamaee le ho hlokomela phetoho ea liparamente tse laoloang.
Boitsebiso ba boleng:
Khoeli e 'ngoe le e' ngoe ea motlakase e na le boleng bo tsitsitseng ba R, empa R ena e ke ke ea e-ba "0" kapa "∞", ha R= "0" e bontša potoloho e khutšoanyane ea ka hare: ha R= "∞" e bontša potoloho e ka hare e bulehileng;ka
Ho hanyetsa ha coil ho ea matlong ho ke ke ha e-ba "0".Haeba maemo a ka holimo a ka finyelloa 'me valve ea solenoid e sa sebetse, e ka' na ea e-ba hore ho kenya letsoho ho fosahetse kapa mokokotlo oa valve o khomaretsoe.

Sensor ea khatello

Kamoo e sebetsang kateng:

Bakeng sa sensor ea khatello ea terata e meraro, e ka utloisisoa e le potentiometer ea terata e meraro kapa e feto-fetohang, hangata e eketsa motlakase oa 5V ho mela e 'meli (mohala o le mong le mela e 3), mme ha boleng bo lekantsoeng bo fetoha, motlakase oa mola bohareng (2 mela) fetoha pakeng tsa 0 le 5V.

Boitsebiso ba boleng:
1. Etella pele moeli o bohareng, fetola letšoao le lekantsoeng, sebelisa multimeter ho lekanya hore na motlakase oa mohala o bohareng (2 mela) o fetoha ka pontšo e lekantsoeng.
2. Tšela sensor ntle le phoso

Ho hlahisoa molao-motheo oa ts'ebetso oa proportional electromagnetic control valve

E itšetlehile ka molao-motheo oa valve ea solenoid on-off: ha matla a tima, selemo se hatella mokokotlo ka ho toba khahlanong le setulo, se etsa hore valve e koalehe.Ha khoele e matlafatsoa, ​​​​matla a makenete a motlakase a hlahisoang a hlola matla a selemo ebe o phahamisa mokokotlo, kahoo a bula valve.Proportional solenoid valve e etsa liphetoho tse ling sebopehong sa valve ea solenoid: e etsa hore ho be le botsitso lipakeng tsa matla a selemo le matla a makenete a motlakase tlas'a likhoele leha e le life tsa hona joale.Boholo ba coil hona joale kapa boholo ba matla a makenete a motlakase bo tla ama sekhahla sa plunger le ho buloa ha valve, 'me phallo ea valve (phallo) le hona joale ea khoele (lets'oao la taolo) ke kamano e nepahetseng ea mela.Valofo e sebetsang ka kotloloho ea solenoid e phalla ka tlas'a setulo.Moemeli o phalla ho tsoa ka tlas'a setulo, 'me tataiso ea matla e tšoana le matla a makenete a motlakase, le ho fapana le matla a selemo.Ka hona, hoa hlokahala ho beha litekanyetso tse kholo le tse nyenyane tsa phallo e lumellanang le sebaka sa ho sebetsa (coil current) sebakeng sa ho sebetsa.The proportional solenoid valve ea Drey fluid e koetsoe (NC, hangata mofuta o koetsoeng) ha matla a tima.
