Ukuhlaziywa kokuthi kungani umlomo womjovo ubhajwe kuzijovo.(ingxenye 1)
1 Ukuqinisekiswa kwezinto zokuhlola
Ngokucutshungulwa kwezizathu ezingaba khona zokunamathiselwa kokuhlanganiswa kwe-nozzle inaliti, kwanqunywa ukuba kwenziwe uchungechunge lokuhlola nokuhlaziya ekuhlanganisweni kombhobho onephutha.Izinto zokuhlola eziqondile zimi kanje:
1) Hlola imvume ehambisanayo yokuhlangana kanye nokufaneleka kwendawo yesihlalo sevalvu yenaliti;
2) Phinda ulinganise ukuzungeza, i-cylindricity, ubulukhuni, nokuqina kwendawo ye-valve yenaliti ngemva kokuhlanza (ukususa ukugqwala kwendawo, njll.);
3) Ukuhlanza (ukususa ukugqwala kwendawo, njll.)
4) Hlukanisa i-valve yenaliti kanye nombhobho, futhi wenze ukuhlolwa kombala endaweni yokukhwelana ye-valve yenaliti kanye nombhobho;
5) Thumela i-valve yenaliti kanye nombhobho ukuze uhlolwe i-metallographic, ulinganise isilinganiso sokungcola.
2 imiphumela yokuhlolwa
2.1 Imiphumela yokulinganisa yobubanzi obungaphandle bendawo yokufaka ivalvu yenaliti kanye nobubanzi bangaphakathi bondawo yokufaka umlomo wombhobho kukhonjiswe kuThebula 1. Phakathi kwazo, izingxenye ezilinganayo ezinenombolo yesitembu i-HHM azifakiwe futhi azisebenzanga.Kusukela kudatha yokulinganisa, kungabonakala ukuthi izikhala ezilinganayo zamasethi amabili okuhlangana zikhulu kunevelu yokuklama, ukuzungeza kwembobo engaphakathi yevalvu yenaliti kanye nombhobho onenombolo yesitembu HD konke kuhlangabezana nezidingo zokuklama, futhi ukuzungeza kwembobo yangaphakathi yevalvu yenaliti kanye nombhobho onenombolo yesitembu ethi HHM kudlula umklamo odingekayo.Indawo engaphezulu yevalvu yenaliti enenombolo yesitembu sensimbi HD ibucayi kakhulu, futhi indawo efanelekile ayinakuhlolwa.Isimo esiqondile sikhonjiswe ku-Figure2.
Indawo efanelekile yevalvu yenaliti enenombolo yesitembu sensimbi i-HHM ibanzi, inomkhawulokudonsa ongaba ngu-2mm, njengoba kukhonjisiwe kuMfanekiso 3 (indawo yokukhwelana izoba mnyama ngemva kokuba umbhangqwana uphansi kancane, ukuze ukwazi ukuhlola isimo sokufaneleka).Ngaphezu kwalokho, i-engeli yekhoni ekupheleni kwevalve yenaliti iyalinganiswa, futhi umklamo udinga i-engeli yekhoni engu-91°±5'.I-engeli yenaliti yenombolo yophawu lwensimbi eqala i-HHM ingu-91°1′, futhi i-engeli yevalvu yenaliti yenombolo yesitembu sensimbi eqala nge-HD ingu-91°2′, kokubili okuhlangabezana nezimfuneko zemidwebo.
