I-100% entsha evavanyiweyo kaloliwe oqhelekileyo weDizili / uMbhobho wesitofu seFuel DLLA155S295c2

Inkqubo yokudilizwa kweperi yomlomo wesitofu (Icandelo 3)

Ukuba umgca wevalve yevalve yenaliti kunye nomzimba we-injector awulingani, unokunyanzeliswa ukuba usebenzisane ngokunkqonkqoza kunye nokunyathela. Faka ivalve yenaliti efakwe kwioyile kumzimba wesitofu, beka itshiphu yeplunger kumqheba wevalve yenaliti, kwaye kancinane ubethe izando ezilishumi elinesibini ngehamile enesiqingatha seponti ukukhusela ivalve yenaliti kunye nomzimba wesitofu sefutha ekubeni ubethwe ngamandla. . Ukuba ucingo lonakele, lujike lube ngama-90° kwaye unkqonkqoze kwakhona, kwaye uyijike kathathu iyonke ukufezekisa ukulingana okuhle.

Kukho iimpawu zomonakalo kucingo lwevalvu yomzimba yokutofa kunye nocingo lwevalvu yenaliti. Ukuba iimpawu zomonakalo zikhulu, sebenzisa inani elincinci le-abrasive intlama erhabaxa kumgca wevalve yentloko yevalve yenaliti, kwaye ubambe isibambo sevalve yenaliti kwisixhobo esikhethekileyo sokuqhawula impembelelo kunye nokusila okujikelezayo. Ukuba une-drill yebhentshi okanye i-drill yesandla, unokufakela i-valve yesibambo senaliti kwi-chuck kwaye uyiguqule ukugaya, kodwa isantya akufanele sikhawuleze kakhulu, ukwenzela ukuba uthintele umgca wevalve ukuba ube nzima ukubuyisela ukugudiswa. ukugaya ngokukhawuleza.

Xa ugaya, kufuneka udibanise umzimba we-injector ngezandla zakho kwaye uqhube ngokuqhubekayo kwaye ujikeleze kwicala le-axial. Sila i-2 ~ 3 imizuzu ukuze ubone indawo edibeneyo yomgca wevalve ye-taper valve. Kodwa ingqwalasela ekhethekileyo kufuneka ihlawulwe kwinto yokuba i-abrasive paste ayifanele isetyenziswe okanye ichukunyiswe kwi-cylindrical guide surface ye-valve yenaliti yokukhusela i-abrasion ekonakaliseni i-sylindrical guide surface ye-valve yenaliti. Gcoba ibala lomonakalo, sebenzisa isirinji ukuphefumlela i-oyile yedizili ecocekileyo, kwaye ugungxule intlama erhawuzelayo kumngxuma womzimba wombhobho. Emva koko sebenzisa i-chromium oxide ukugaya umzimba we-injector ngendlela efanayo njengoko kubonisiwe kwi-Figure 6, kwaye emva koko ugaye nge-oyile ye-injini ye-1 ~ 2min, ukwenzela ukuba umgca wevalve we-valve ye-naliti ye-taper ufikelele kwindawo ejikelezileyo. Ububanzi bomphezulu odibeneyo wocingo lwevalve ngokuqhelekileyo malunga ne-0.1mm.
