Umgangatho ophezulu we-injini ye-Diesel Fuel Injector Nozzle Dlla160sn731

Ukuqhaqha kunye nokuHlolwa kweNtloko ye-Injector kunye neZakhono zokuLungisa ukuSila zeumbhobho wesitofuUkudibanisa (inxalenye2)

2 iTekhnoloji yoBuyiselo lweumbhobho wesitofu Ukudibanisa

Ukuchaneka komphezulu we-cylindrical guide of the umbhobho wesitofu iphezulu kakhulu. Umsantsa wendibano phakathi kwayo kunye ne umbhobho wesitofu umngxuma yi 0.002 ~ 0.006mm, kunye ne umbhobho wesitofu kufuneka ikwazi ukutyibilika ngokukhululekileyo phezulu nasezantsi kwi umbhobho wesitofu umngxuma womzimba. Umphezulu we-cylindrical guide we umbhobho wesitofu imnyama, kwaye ukuba ukulingana kukhululekile kakhulu, kuyimfuneko ukukhetha i umbhobho wesitofu ngokuqina okufanelekileyo ngakumbi. Ukuba i umbhobho wesitofu kwaye i umbhobho wesitofu umzimba uxinene kakhulu, ungasebenzisa ngokubanzi ioyile yomatshini kwindawo yesikhokelo yecylindrical umbhobho wesitofu kuqala, kwaye ke usila umbhobho wesitofu. Ukuba iqinile kakhulu, inokucolwa ngechromium oxide.

Ukuba umgca wevalve ye umbhobho wesitofu kwaye i umbhobho wesitofu umzimba awulingani, bobabini banokunyanzelwa ukuba basebenzisane nge-percussion kunye nesitampu. Beka i umbhobho wesitofu ifakwe kwioli kwi umbhobho wesitofu umzimba, seta i-punch (Figure 4, Figure 5) kwi umbhobho wesitofu phatha, kwaye ucofe kancinci ihamile elinesiqingatha ngehamile yeponti (ukuthintela umbhobho wesitofu ukusuka ekubetheni ngamandla Umgca wevalve we umbhobho wesitofu umzimba wonakele) jika iminyaka engama-90° kwaye unkqonkqoze kwakhona, kwaye uyijike kathathu iyonke ukufezekisa ukulingana okuhle.

Kukho iimpawu zomonakalo kwi umbhobho wesitofu ucingo lwevalvu yomzimba kunye umbhobho wesitofu ucingo. Ukuba iimpawu zomonakalo zinkulu, sebenzisa inani elincinci le-abrasive intlama erhabaxa kumgca wevalve ye umbhobho wesitofu intloko, kwaye uyibambe i umbhobho wesitofu isiphatho kwisixhobo esikhethekileyo sokuqhaqha sempembelelo kunye nokugaya okujikelezayo. Ukuba une-drill yebhentshi okanye i-drill ngesandla, ungayifaka umbhobho wesitofu phatha i-chuck kwaye uyijike ukuze ugaye, kodwa isantya akufanele sikhawuleze kakhulu, ukuze uthintele umgca wevalve ukuba ube nzima ukubuyisela ukugudiswa ngenxa yokugaya ngokukhawuleza.
