Te Injector Diesel Fuel Injector 0445120240 Bosch mo te keehi / New Holland Cummins Engine

Hei whakaroa i te oranga o te mahi o te injector me te whakapai ake i te tere kati o te valve ngira, me whakamahi te injector inertia iti mo te miihini diesel me te tere hurihuri nui atu i te 3000r / min. Engari he iti te diameter o te puna injector inertia iti, he nui te ahotea miihini me te ahotea waiariki, no reira kua pai ake nga whakaritenga o te kounga o te puna. I tua atu, ki te whakaiti ake i te inertia nekehanga, ka taea te whakamahi i te tikanga o te whakaiti i te diameter o te valve ngira ki te whakaiti ake te inertia nekehanga o te injector wahie. Ko te iti o te inertia o te injector wahie he pai mo te aukati i te cavitation i runga i te mata o te nohoanga ngira, karo i te haaputuputuraa waro mau i roto i te pupuha wahie meinga e te hau backflow, me te whakaroa werohanga i puta i te tauhohenga huakore o te piha ngira. Hei tauira, ka whakamahia e te miihini miihini YG6105QC te injector wahie inertia iti.

Ko te pehanga werohanga (te kaha j) o te miihini miihini he tohu nui mo te punaha wero wahie. I te wa e mau ana etahi atu tawhā o te punaha werohia, ka whakatauhia te pehanga werohanga e te pehanga werohanga. Ko te pehanga werohia noa o te miihini diesel 12150L he 21 MPa, engari ka heke haere me te tipu o te oranga ratonga. I muri i te paunga o te ratonga, ka heke ki te 17.3 ~ 19.4 MPa. Ko te maturuturu o te pehanga tiimata ka anga whakamua te werohanga, ka piki ake te roa o te werohanga, ka piki te tuku hinu, ka arahi ki te pikinga o te mana miihini diesel. I te wa ano, ka heke te tere o te werohanga wahie, ka whakapotohia te awhe kurupae hinu, ka piki te diameter toharite o te matūriki hinu v, ka heke te kounga rehu, ka heke te wera, ka puta te heke ohaoha o te miihini diesel. I tua atu, he ngawari hoki te tiimata o te heke pehanga ki te hanga i te putunga waro ki te upoko o te puera ngira.
