Inkingi yo hejuru ya valve y'imodoka ni iyihe?
Urufatiro rw'imodoka, akenshi rwitwa valve tappet cyangwa valve tapple, ni ingenzi cyane muri sisitemu ya valve ya moteri. Ishinzwe cyane cyane guhindura ingendo ya camshaft ikajya mu nzira yo hejuru no hasi y'inzira ya valve, bityo ikagenzura neza uburyo valve zifunguka n'izifungwa.
Imikorere y'ibanze:
Nk'umukurikira wa kamera, agace k'ingufu kakira imbaraga zivuye kuri kamera hanyuma kakazishyira kuri pushrod cyangwa kuri valve.
Mu gihe cyo kohereza umuvuduko, igomba kandi kwihanganira imbaraga zo ku ruhande zikoreshwa na kamera no kohereza izo mbaraga ku mutwe wa silinda cyangwa ku gice cy'imashini kugira ngo ikomeze gukora neza.
Icyiciro cy'ingenzi:
Tappet ya Mechanical: Inyubako yayo ni yoroshye kandi igiciro ni gito, ariko ishobora gutanga urusaku rwinshi mu gihe cyo kuyikoresha kandi igasaba ko inyuzwamo valve ihinduka n'intoki kugira ngo ihuze n'ubushyuhe cyangwa ubusaza bwayo.
Hydraulic Tappet: Ikoresha umuvuduko w'amavuta imbere mu guhinduranya, bigatuma aho valve ihagarara haba zeru, bityo bigabanura cyane urusaku rwa moteri kandi bigatuma imikorere yayo iba myiza. Ariko, imiterere yayo iragoye kandi ikiguzi kiri hejuru.
Ibiranga imiterere n'ibikoresho:
Kugira ngo ugabanye uburemere, agace k'agace k'agace ka valve gashyirwa hejuru gasanzwe gakozwe nk'imiterere y'uruziga.
Roller Tappet ni ubwoko busanzwe, bugabanya gukururana n'imbaraga zo ku ruhande binyuze mu miterere y'umuzingo, bikanoza imikorere, ariko imiterere yayo iragoye cyane kandi ikoreshwa cyane cyane mu bihe bikomeye nko muri moteri nini zitwara mazutu.
Ibikoresho bisanzwe birimo icyuma gikozwe muri nickel-chromium alloy, icyuma gikozwe muri alloy gikonje, cyangwa icyuma gikomeye cyane. Ubuso bwo gukururana busaba ubushyuhe no gusya neza kugira ngo bwongere ubushobozi bwo kwangirika. Ikoranabuhanga rigezweho rinakoresha uburyo bwo gutunganya ubuso nka DLC (Diamond-like Carbon) coating kugira ngo bigabanye uburyo bwo gukururana.
Akamaro n'Uburinzi:
Imikorere ya valve tappet igira ingaruka zitaziguye ku ikoreshwa ry'amashanyarazi ya moteri, uburyo ikoresha lisansi mu buryo butaziguye, ndetse n'urwego rw'ibyuka bihumanya ikirere. Iyo habayeho amakosa nko kwangirika, guhinduka cyangwa gufata, bizatera gufungura no gufunga bidasanzwe kwa valve, bigatera guhindagurika kwa moteri, gutakaza ingufu, no kwiyongera kw'ikoreshwa rya lisansi.
Kugira ngo yongere igihe cyo kuyikoresha, guhindura amavuta buri gihe no kuyibungabunga moteri ni ngombwa kugira ngo igire ubushobozi bwo kuyisiga neza.
Imashini yo gufunga (izwi cyane nka "valve tappet") ni igice cy'ingenzi muri sisitemu ya moteri yo gufunga moteri. Inshingano yayo nyamukuru ni uguhindura ingendo yo kuzenguruka ya camshaft ikayihindura ingendo ijya hejuru no hasi y'imashini, bityo ikagenzura uburyo ifungura n'ifunga ry'imashini zinjira n'izisohora umwuka, ikareba ko moteri irangiza imirongo ine yo gufunga, gukanda, gutanga ingufu, no gusohora umwuka.
Imirimo yihariye ishobora kugabanywamo ingingo zikurikira:
Kohereza ingendo n'imbaraga: Yakira umuvuduko uva kuri camshaft hanyuma akawushyira kuri pushrod cyangwa kuri valve, bigatuma valve ifunga ku gihe cyagenwe.
Guhangana n'imbaraga zo ku ruhande: Mu gihe cyo kuzenguruka kwa kamera, imbaraga zo ku ruhande zirakorwa, kandi agace k'imashini gakeneye kohereza izo mbaraga ku mutwe wa silinda cyangwa ku gice cy'imashini kugira ngo gakomeze kugenda neza.
Guhindura uburyo bworoshye uburyo bwo gusohora imvange (ubwoko bwa hydraulic): Moteri zigezweho zikoresha cyane utumashini twa hydraulic, twuzuyemo amavuta kandi dushobora kwishyura uburyo bworoshye uburyo imvange isohoka bitewe n’ubushyuhe cyangwa ubusaza, bigatuma "ikoreshwa rya zero", bityo bigabanura cyane urusaku rwa moteri kandi bikanoza uburyo bwo gukora.
Kugabanya ibisabwa mu kubungabunga: Utwuma duto two mu bwoko bwa hydraulic ntabwo dukenera guhinduranya intoki aho valve ihagarara, bikoroshya uburyo bwo kubungabunga moteri.
Iyo agakoresho ko gushyiramo amashanyarazi (cyane cyane ubwoko bwa hydraulic) kananiwe, nko kwangirika, gusohora amavuta, cyangwa umwuka winjira imbere, bizatera urusaku "rudasaza" (rugaragara cyane muri moteri zikonje) kandi bishobora gutera ibura ry'amashanyarazi, kwiyongera kw'ikoreshwa rya lisansi, cyangwa ibibazo by'ibyuka bihumanya.
Impamvu zikunze kugaragara zirimo umuvuduko udahagije w'amavuta, urugero rw'amavuta ruri hejuru cyane cyangwa hasi cyane, cyangwa ubushyuhe bw'amavuta budahuye.
Kubwibyo, guhindura amavuta buri gihe no kubungabunga sisitemu isanzwe yo kwisiga ni ingamba z'ingenzi zo kongera igihe cyo gukora kwa valve tappet no kwemeza imikorere ya moteri.
