Sekhahla sa solenoid valve 457-9878 hydraulic pump proportional solenoid valve

1, sebopeho sa li-valve tse lekanang.

Proportional valve ke mofuta o mocha oa sesebelisoa sa hydraulic control. Khatello, phallo, kapa tsela ea molapo oa oli e ka laoloa u le hole ho latela lets'oao la motlakase le kentsoeng khafetsa le ka tekanyo. The proportional valve e entsoe ka likarolo tse peli: sesebelisoa sa phetoho ea electro-mechanical proportional le 'mele oa hydraulic control valve.

Ho na le mefuta e mengata ea li-electromagnetic electromagnets, empa molao-motheo oa ts'ebetso oa ts'oana, 'me kaofela li ntlafalitsoe ho latela litlhoko tsa taolo ea valve ea proportional. Mosebetsi oa eona ke ho tsoela pele le ka ho lekana ho fetola pontšo ea motlakase oa motlakase ka matla a mochine le tlhahiso ea ho falla, 'me ea morao e hlahisa khatello le ho phalla ka mokhoa o lekaneng le ho tsoela pele ka mor'a ho amohela matla a mochine le ho falla.

2. Molao-motheo o sebetsang oa valve e lekanang.

Letšoao la taelo le matlafatsoa ke proportional amplifier, le proportional output current ho proportional solenoid ea proportional valve, proportional solenoid output force le motsamao o lekanang oa boemo ba mantlha ba valve, o ka laola ka tsela e lekanang phallo ea phallo ea metsi le fetola tsela eo metsi a phallang ka yona, e le ho fihlella boemo kapa taolo ya lebelo la sehlomathisi. Lits'ebetsong tse ling tse hlokang boemo bo phahameng kapa ho nepahala ha lebelo, sistimi ea taolo e koetsoeng e ka boela ea etsoa ka ho lemoha phallo kapa lebelo la actuator.

Molao-motheo oa proportional solenoid valve

E itšetlehile ka molao-motheo oa solenoid switch valve: ha matla a khaotsoe, selemo se hatella mokokotlo oa tšepe ka ho toba khahlanong le setulo, ho koala valve. Ha khoele e matlafatsoa, ​​matla a motlakase a hlahang a hlola matla a selemo ebe o phahamisa mokokotlo, kahoo a bula valve. The proportional solenoid valve e etsa liphetoho tse ling sebopehong sa solenoid on-off valve: matla a selemo le matla a motlakase a leka-lekaneng tlas'a khola efe kapa efe ea hona joale. Boholo ba hona joale ba coil kapa boholo ba matla a motlakase bo tla ama ho otla ha plunger le ho buleha ha valve, 'me ho buloa ha valve (sekhahla sa phallo) le hona joale (letšoao la taolo) li na le kamano e nepahetseng ea mela. . Li-valve tsa solenoid tse sebetsang ka kotloloho li phalla ka tlas'a setulo. Mohare o phalla tlas'a setulo sa valve, 'me tataiso ea eona ea matla e tšoana le matla a motlakase, empa e fapane le matla a selemo. Ka hona, hoa hlokahala ho beha kakaretso ea litekanyetso tse nyenyane tsa phallo e lumellanang le sebaka sa ts'ebetso (coil current) sebakeng sa ts'ebetso. Ha motlakase o tima, valve ea Drake liquid proportional solenoid ea koaloa (hangata e koetsoe).

Mosebetsi oa proportional solenoid valve

Taolo ea throttle ea lebelo la phallo e finyelloa ka ho laola motlakase (ha e le hantle, taolo ea khatello e ka boela ea finyelloa ka liphetoho tsa moralo, joalo-joalo). Kaha ke taolo ea throttle, ho tlameha ho ba le tahlehelo ea matla.
