Ivaluvu Yevalvu Entsha Yekhwalithi Entsha Entsha Evamile Yokulawula Injector F00VC01509 Valve Assembly for Fuel Injector Engine Engine Parts

Enqubweni yokuqinisekisa ibhentshi, amandla kanye nokusetshenziswa kukaphethiloli kwenjini kadizili kwancipha ngokuqhubekayo. Ngemva kokuhlolwa, inani likawoyela lomjovo liyehliswa, futhi kwatholakala ukuthi isihlalo sokuvala somzimba wevalvu yenaliti yomlomo sasigugile kakhulu. Ngokwedatha yokuhlola, ukuguga kwesihlalo esivalayo somzimba wevalvu yenaliti kubangelwa amandla omthelela amaningi endaweni yesihlalo sokuvala lapho kumiswa ivalve yenaliti yomjovo. Ngokuthuthukisa i-valve yokulawula i-injector nokunciphisa ububanzi be-valve yenaliti, amandla omthelela we-valve yenaliti endaweni yesihlalo sokuvala ayancishiswa. Umjovo othuthukisiwe uqinisekiswe ukuqina kwenjini. Ngesikhathi sokuhlolwa ukuqina, amandla nokusetshenziswa kukaphethiloli kuzinzile, futhi ukuguga kwesihlalo sotywino somzimba wephinifa kusese ngaphakathi kwenani elilinganiselwe. Inkinga isixazululiwe. Isixazululo sale nkinga sihlinzeka ngesipiliyoni nereferensi yokwakhiwa kwevalvu yokulawula umjovo, futhi sinikeza ukwesekwa kwedatha ngamandla okuthinta isihlalo sokuvala somzimba wevalvu yenaliti esingamelana nayo.Ukuguga kwesihlalo somzimba wevalve yenaliti yomjovo wedizili kuthinta kakhulu ukuma kwesifutho sikaphethiloli nezici zokujova uphethiloli. Kuhloswe umonakalo odalwe ukuhlangana kwe-valve yenaliti ngaphansi kwesenzo semvamisa ephezulu kanye nomjikelezo womthelela wokucindezeleka okukhulu, ukuhlolwa kokukhathala kokuxhumana, isibonakhulu se-metallographic (OM) enohlelo lokuhlaziya isithombe kanye nesibonakhulu se-electron yokuskena indawo eshisayo kwasetshenziswa ukutadisha ukwehluleka ungqimba lwe-coating yesihlalo se-valve yenaliti kanye nokuziphatha okuguquguqukayo kwesihlalo se-valve yenaliti ngaphansi kokucindezeleka okuhlukile nezindlela zokulayisha. Imiphumela ibonisa ukuthi imodi yokulimala yokukhathala eyinhloko yokuhlanganisa i-valve yenaliti ngaphansi kwezindlela ezihlukene zokulayisha ukulimala kokukhathala kokuxhumana kokugcina kokugcina kwesisekelo senaliti ye-valve. Phakathi kwazo, ukusatshalaliswa kwengcindezi yokuxhumana okungaphezulu komzimba we-valve olayishwayo ohambisana newashi ufana, futhi umkhawulo wokukhathala uphezulu (228 MPa), kuyilapho ukulayisha kwendawo yesinyathelo kuthambekele ekulayisheni okungalingani, okuholela ekulimaleni kokukhathala kuqala kugxile engxenyeni. indawo yesiyingi, ukulimala kokukhathala kanye nokulimala akulingani, futhi umkhawulo wokukhathala uncane, kuphela i-74.6% yokulayisha okuphezulu.
