I-High Performance Delivery Valve K15 ye-Injection Pump Diesel Engine Spare Parts ye-ISUZU KUBOTA ISEKI

1. Isakhiwo se-valve yokulethwa

(1) I-valve yokuletha uwoyela nesihlalo se-valve izingxenye ezinembayo, ezenziwe ngensimbi ye-alloy yekhwalithi ephezulu. Izimbobo zazo eziqondisayo, ubuso baphezulu naphansi ekugcineni kanye nezimbobo zezihlalo zicutshungulwa ngokunemba futhi ziphansi, futhi azikwazi ukushintshaniswa ngemva kokumataniswa.

(2) Ingxenye yekhoni yevalvu yokukhipha uwoyela iyindawo ye-axial sealing cone yevalvu. Ingxenye yekhoni yevalvu ishelela embotsheni yomhlahlandlela futhi idlala indima yokuqondisa. Umsila wenziwa ngomshini onama-grooves ukuze wenze i-cross-section ukuze uphethiloli udlule. I-cylindrical surface emaphakathi nevalve yokuletha uwoyela ibizwa ngokuthi i-decompression zone, eyenza ivolumu yokunciphisa nge-cone yokuvala.

(3) Indawo engezansi yokugcina yesihlalo se-valve kanye nengaphezulu lomkhono we-plunger wenziwe ngomshini ngokunemba futhi ufakwe ngokuqinile. Aqiniswa yinadi elicindezelwe ngetorque ecacisiwe yokuqinisa. Kukhona iwasha yethusi evala umfutho ophezulu yogqinsi oluthile phakathi kwenadi elicindezelayo kanye nesihlalo sevalvu. Kukhona futhi i-gasket yokuvala ingcindezi ephansi phakathi kwentongomane yokuminyanisa ivalvu yokulethwa kukawoyela kanye nobuso obuphezulu bendlu.

(4) Isiqukathi sokunciphisa esibolekile sifakwa endaweni engaphakathi yentongomane yokuminyanisa ivalvu yokudiliva uwoyela ukuze kuncishiswe umthamo wesikhala esingaphakathi, sikhuthaze ukuma komjovo ngokushesha, futhi kukhawulelwe ukuphakama okuphezulu kwevalvu yokukhipha uwoyela.

2. Umsebenzi we-valve yokulethwa

(1) Vimbela ukuconsa kukawoyela ngaphambi komjovo futhi ukhuphule isivinini somjovo: Lapho iphampu yomjovo kaphethiloli inikezela uwoyela, ngemva kokuba umfutho kawoyela ungaphezu kwamandla okulayisha kuqala wesiphethu sevalvu yokuletha uwoyela kanye nokucindezela okusalayo epayipini likawoyela elinomfutho omkhulu, ivalve yokukhipha uwoyela Ivalvu kawoyela iyakhuphuka futhi ikhoni yayo yokuvala ishiye isihlalo sevalvu. Kudingekile ukulinda kuze kube yilapho ibhande lokunciphisa ingcindezi ku-valve yokulethwa kwamafutha lishiya ngokuphelele imbobo yomhlahlandlela wesihlalo se-valve ngaphambi kokuba uphethiloli ekamelweni likawoyela wepompo lingangena epayipini likawoyela elinomfutho ophezulu.

(2) Vimbela uwoyela ukuconsa ngemva komjovo futhi ukhuphule isivinini sokuvala: Lapho ukunikezwa kukawoyela kumiswa, ngokushesha nje lapho unqenqema oluphansi lwebhande lokukhulula i-valve yokukhipha uwoyela lungena kumsele, indlela ephakathi kwepayipi likawoyela elinomfutho ophezulu. negumbi lokumpompa linqanyuliwe. Lapho i-valve yokuletha uwoyela ihlezi ngokuphelele, yehla ibanga h, ngakho umthamo wepayipi likawoyela elinomfutho ophezulu uyanda, okwenza umfutho kawoyela wehle ngokushesha ngo-1MPa ~ 2MPa, futhi uwoyela unqanyulwa ngokushesha futhi kalula, ukuvimbela ukuguquguquka kwengcindezi kawoyela kanye "nokuncipha kwamapayipi" ekubangeleni ukwanda kwamafutha. "Futhi ukhiqize amafutha aconsayo ngemva kokufutha. (3) Vimbela uphethiloli ukuthi ungabuyeli emuva futhi ugcine ingcindezi ethile eyinsalela epayipini likawoyela elinomfutho ophezulu.
