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 pontšo e lekantsoeng, sebelisa multimeter ho lekanya hore na motlakase oa mohala oa 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 a phahamisa mokokotlo, ka hona 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. Direct acting proportional solenoid valve 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 tse 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.
