Izinhlobo ezi-3 zamavalvu okulawula asetshenziswa kuma-Hydraulic Systems

Izinhlelo zamandla we-hydraulic zivame kakhulu emkhakheni wezimoto, imoto, kanye nemishini ye-aerospace. Banesilinganiso esiqinile samandla nesisindo kanye nokukwazi ukungenzi lutho, ukusebenza ngezikhathi ezithile ngisho nokuhlehliswa. Angakwazi futhi ukuhamba ngokushesha, futhi asabele ngokushesha. Enye inzuzo ekhangayo yedivayisi yokulawula uketshezi ukuthi ngaphezu kokuletha amazinga okusebenza azinzile ingaba yesikhathi eside kakhulu. Uzocubungula ivalvu eyodwa noma amabili e-hydraulic ikakhulukazi uma uhlola izingxenye zemishini/imishini esebenza ngamanzi. Emakethe uzothola izinhlobo ezahlukene zamavalvu asebenza ngogesi akhiqizwa abakhiqizi abahlukahlukene. Ngokusekelwe emsebenzini owenziwe ama-valve anjalo angafeza izindima ezihlukene. Imishini eminingi esebenza nge-hydraulic idinga i-valve ezimele, kanti eminye isebenza ngengxube yamavalvu.

Manje ake siqhubeke nezisekelo zamavalvu asebenza ngogesi. I-hydraulic valve iyithuluzi le-elekthronikhi elisetshenziselwa ukulawula uketshezi noma ukunyakaza kwegesi kulo. Ama-valve e-hydraulic alawula ukugeleza ngokuvula nokuvala uhlelo. Ama-valve anjalo avame ukwakhiwa ngezinto eziqinile (insimbi noma insimbi) ukuze abekezelele ukucindezela koketshezi olusindayo olungaphezu kuka-3000psi. Sinamasu amaningana okuvula iphampu enamanzi. Angase alawulwe mathupha, kusetshenziswa uthi, ifindo noma ikhamera, anikwe amandla yi-solenoid, noma alawulwe umshayeli wendiza. Ama-valve aqhubekayo okuvula/avala ayizigaba ezimbili zokusebenza.

Amavalvu Okulawula Iziqondiso

Ama-valve okulawula ukuqondisa asetshenziselwa ukulawula ukugeleza koketshezi olusuka ohlelweni. Ama-valve anjalo azoma futhi aqalise kabusha ukugeleza koketshezi. Ngokuvamile, bangakwazi ukulungisa indlela yokugeleza kwamanzi. I-valve yokuhlola, i-valve yokugcwalisa kusengaphambili, ama-spool valves, njll. amavalvu ahlukene okulawula asemaceleni asetshenziselwa ukugcina ukunyakaza koketshezi olwanele ngaphakathi kwedivayisi. Amavalvu angabuyi amavalvu okuhlola kanye namavalvu okugcwalisa kuqala. Amavalvu okuhlola avimba indlela kanye nokungqubuzana kwegesi eqondiswa kabili. Iphampu yokugcwaliswa kuqala, ngakolunye uhlangothi, idlulisela uketshezi kusilinda esisebenza ngaphansi kwamanzi kanye ne-reservoir. Ukunyakaza koketshezi ngaphakathi kwedivayisi kulawulwa ama-spool valves.

Ivalvu yokulawula indlela yezindlela ezi-2 iyivalvu yokulawula inkomba elula, enamachweba amabili okungena nokuphumayo. Izindlela ezinjalo zitholakala kumpompi wamanzi, ngakho ukunyakaza kwamanzi kungase kuqhubeke noma kuphele. Ivalvu yokulawula indlela yezindlela ezintathu inezimbobo ezi-3 ezibizwa ngokuthi i-inlet, i-outlet kanye nezimbobo zokukhipha umoya. Lezi zitholakala kumashubhu acuphayo owodwa, ngakho zonke izimbobo zingavinjwa ishubhu lesithathu elisebenzayo. Ngokunjalo, ama-valve ezindlela ezi-4 kanye nama-valve ezindlela ezi-5 asetshenziswa ngokulandelana kuma-actuator asebenza kabili kanye namasekhethi omoya.

I-Pressure Controling Hydraulic Valve

I-valve yokunciphisa umfutho we-hydraulic isiza ekulawuleni ukuvuza nokuqhuma kwamapayipi. Amavalvu okulawula ukucindezela aqapha umfutho wamanzi oweqile odlula epayipini. Lawa ma-valve agcina ukucindezela okufinyelelwe opharetha ngesandla. Izitayela ezahlukene i-hydraulic pressure relief valve, i-valve yochungechunge, i-counterbalance valve kanye ne-valve yokunciphisa ingcindezi. I-valve ye-counterbalance ikhiqiza indlela eyinkimbinkimbi namandla e-valve yochungechunge, izwa ukucindezela okukhulu. Enye yezinhlobo ezibalulekile ze-valve yokusiza ingcindezi ukuthi ibeka i-cap yokucindezela ngokuhambisa ngokweqile emuva ethangini.

umfutholuketshezi Flow Control Valve

Ama-valve okulawula ukugeleza asetshenziselwa ukuqapha nokulungisa ukugeleza koketshezi noma igesi ngohlelo. Lawo ma-valve angakhuphula ukusebenza kahle kohlelo lwe-hydraulic. Ama-valve okulawula ukugeleza asetshenziselwa ukulandelela nokulawula ukuguquguquka kwengcindezi yesistimu. Ivimbela ukugeleza ezingxenyeni ezingaxhaswanga zenethiwekhi.

Izibonelo zamavalvu okulawula ukugeleza zifaka i-throttle valve, i-valve yokulawula isivinini, i-valve yokugeleza efakwe ngamananifold, njll. Isihlukanisi sokugeleza singolunye uhlobo lwevalvu yokulawula ukugeleza. Le valve ithatha uketshezi okokufaka emthonjeni owodwa bese iluqondisa kabusha emithonjeni emibili noma ngaphezulu.

I- GRH  ikhethekile ekuhlinzekeni ngezakhi zamanzi nezisombululo ezinhlelweni ezisebenza ngogesi. Ngokuthuthuka okuqhubekayo nomdlandla kule minyaka engu-30 edlule, i-GRH ibilokhu ingamandla asafufusa embonini yamandla oketshezi kusukela yasungulwa ngo-1986.GRH inokubambisana okuseduze namakhasimende ethu ngokunikela. izixazululo zabo kumasistimu we-hydraulic. Uma unezidingo, sicela ukhululeke ukuxhumana.
