Sethapo sa selenoid sa excavator sete 423-4562 proportional solenoid valve

Molao-motheo oa ts'ebetso ea li-valve tsa electromagnetic proportional le ho lemoha:

Taolo ea li-valve e ka aroloa ka mefuta e 'meli:
E 'ngoe ke taolo ea switch: e ka buloa ka botlalo kapa e koetsoe ka botlalo, sekhahla sa phallo e kanna ea ba se seholo kapa se nyane, ha ho na boemo ba lipakeng, joalo ka li-valve tse tloaelehileng tsa motlakase ka li-valve, li-valve tse khutlisetsang morao tsa motlakase, li-electro-hydraulic reversing valves.
E 'ngoe ke taolo e tsoelang pele: sekepe sa valve se ka buloa ho ea ka tlhokahalo ea tekanyo leha e le efe ea ho bula, ka hona ho laola boholo ba phallo, li-valve tse joalo li na le taolo ea matsoho, tse kang li-valve tsa throttle, empa hape li laoloa ka elektronike, tse kang proportional. li-valve, li-valve tsa servo.
Kahoo morero oa ho sebelisa proportional valve kapa servo valve ke: ho finyella taolo ea phallo ka taolo ea elektronike (ha e le hantle, ka mor'a liphetoho tsa meralo e ka boela ea finyella taolo ea khatello, joalo-joalo), kaha ke taolo ea throttling, ho tlameha ho ba le tahlehelo ea matla, servo. li-valve le li-valve tse ling li fapane, tahlehelo ea matla a eona e kholoanyane, hobane e hloka phallo e itseng ho boloka mosebetsi oa potoloho ea oli ea pele ho sethaleng.

Molao-motheo o sebetsang oa proportional solenoid 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.khoele
Ha motlakase o sebelisoa, matla a makenete a hlahisoang ke motlakase a hlōla 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 phahameng le tse fokolang tsa phallo e lumellanang le sebaka sa ts'ebetso (coil current) sebakeng sa ts'ebetso.The proportional solenoid valve ea Drey fluid e koetsoe (NC, hangata mofuta o koetsoeng) ha matla a tima.
