Ukuhlolwa kwesitofu - Iingcebiso zesitofu
(1) Sebenzisa iglasi yokukhulisa ukukhangela umngxuma womlomo wesitofu samafutha kunye nesiphelo sentloko yomlomo womlomo, uze uzithelekise nentloko yomlomo omtsha. Intloko yesitofu samafutha kufuneka ilahlwe ukuba inayo nayiphi na kwezi meko zilandelayo:
I-1 I-Abrasive wear, olu hlobo lokugqoka luya kwenzeka ngaphakathi kwentloko ye-injector, ngoko ke, omabini amacala angaphakathi nangaphandle kufuneka ahlolwe.
2 Kukho i-corrosion, i-ablation umonakalo kunye nokushisa, okuvame ukubangelwa ngamanzi aphezulu, i-asidi kunye nomxholo we-sulfure kwi-fuel okanye ngenxa yomsebenzi ogqithiseleyo.
3 Umngxuma wokutshiza wandiswa okanye ukhubazekile, obangelwa ukucoca umngxuma wokutshiza nge-drill okanye ezinye izixhobo kwaye uyisebenzise ixesha elide. Qaphela ukuba ubukhulu bomngxuma wombhobho wentloko yesitofu akufunekanga butshintshwe. (2) Jonga ubume bomphezulu wokudibanisa iplunger kwintloko yomlomo. Khetha iplunger entsha kwaye uyipeyinte bluwu yePrussian. Faka i-plunger kwincam ye-injector kwaye uyiguqule i-90 °. Izitofu zingaphinda zisetyenziswe ukuba indawo yokudibanisa iplunger iyaqhubeka kwaye ithatha i-40% yendawo ejikeleze ikhowuni yencam yesitofu okanye ibhore yeplunger. Ngelo xesha, i-plunger kufuneka idibane nommandla we-cone ukusuka kwi-1/4 ukuya kwindawo yonke ye-cone kwintloko ye-nozzle. Iingcebiso zomlomo ezinomphezulu woqhagamshelwano ngaphantsi kwe-1/4 yendawo yokuphela kwencam yomlomo ayinakusetyenziswa. Ukuba indawo yokudibanisa i-tip ye-injector isekupheleni, indawo yoqhagamshelwano yayo kufuneka ibe mkhulu kune-1/2 yendawo ye-cone. Sebenzisa umvavanyi ukujonga ukuvuza kweoyile ye-injector kunye neplunger. 3) Khangela umonakalo kunye nokungalingani kwendiza yokugqibela yomkhono we-plunger wentloko ye-injector. Jonga ukungalingani komphezulu kunye nepleyiti ecwebileyo (ngokukhethekileyo iplate yomhlaba) kunye ne "blueing agent". Ukuba intloko yomlomo ifunyenwe yonakele okanye ayilingani, yiphawule ukuba ilungiswe.
(4) I-injector yamafutha inokuhlolwa ngokutshiza kwisixhobo esikhethekileyo sokulondoloza. Esi sixhobo sinokusetyenziselwa ukujonga incam ye-injector ngaphambi kokuba ifakwe kwi-injector.
