Isitofu seNozzle DLLA158P1096 yeCommon Rail Injector 093400-1096

Inkqubo yokuqhaqha yeperi 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 se-fuel, beka itshiphu yeplunger kwisiphatho sevalve yenaliti, kwaye kancinane ubethe izando ezilishumi elinesibini ngehamile enesiqingatha seponti ukunqanda ivalve yenaliti kunye nomzimba wesitofu se-fuel ukuba ungabethelwa ngamandla. .Ukuba ucingo lonakaliswe, luphendulele i-90 ° kwaye lunqonqoze kwakhona, kwaye lujike kathathu lilonke ukuze lufezekiseke kakuhle.

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 isiphatho sevalve yenaliti kwisixhobo esikhethekileyo sokuqhawula impembelelo kunye nokusila okujikelezayo.Ukuba une-drill yebhentshi okanye i-drill yesandla, unokufaka i-valve yesibambo senaliti kwi-chuck kwaye uyijike ukuze ugaye, kodwa isantya akufanele sikhawuleze kakhulu, ukwenzela ukuba ukuthintela umgca wevalve ukuba ube nzima ukubuyisela ukugudiswa ngenxa. 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 ukuthintela 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 kuMfanekiso 6, kwaye emva koko ugaye nge-oyile ye-injini ye-1 ~ 2min, ukwenzela ukuba umgca wevalve we-valve ye-naliti ye-taper ufikelele kwi-smodeness ejikelezileyo.Ububanzi bomphezulu odibeneyo wocingo lwevalve ngokuqhelekileyo malunga ne-0.1mm.
