Cov neeg siv yuav tsum paub txog cov xwm txheej uas tuaj yeem ua rau hnav thiab kua muag ntawm lub tshuab hluav taws xob teeb kom tsis txhob hnav thiab kua muag ntau dhau.
Yog hais tias diesel muaj cov sulfur lossis lwm yam impurities, cov tshuaj corrosive xws li acids yuav tsim thaum lub zog sib txuas; Yog tias muaj ntau cov leb feem ntau hauv cov roj duas, nws yog ib qho yooj yim los tsim cov roj carbon deposits tom qab kev hnav ib qho kev hnav, ua rau muaj kev sib txuas lus ntawm lub nplhaib piston thiab lub tog raj kheej; Lub viscosity ntawm diesel tuaj yeem cuam tshuam rau tsim ntawm kev sib xyaw thiab kev ntseeg tau ntawm cov khoom siv roj. Rau cov roj lubricating, viscosity thiab oxidation tsis tseem ceeb yog qhov tseem ceeb tshaj plaws, yog li siv cov kev ua haujlwm ntawm Volvo Generator teeb, thiab yog li ntawd tsis tuaj yeem siv cov neeg nyiam.
Cov txiaj ntsig kev sim qhia tau tias kev sib txhuam ntawm cov roj diesel nce nrog kev nce ntawm kev ceev thiab thauj khoom. Vim tias thaum lub thauj khoom nce, chav ntsuas siab rau kev sib txhuam cov nplaim thiab cov mob thermal tsis zoo. Thaum qhov ceev nce ntxiv, kev sib txhuam quab yuam ib lub sijhawm nce ib nrab, tab sis tib lub zog, qhov nce hauv kev ceev tshaj qhov nce ntawm kev nce. Txawm li cas los xij, qis dhau qhov nrawm tsis tuaj yeem lav cov kua roj lubrication lubrication, uas tseem nce hnav. Yog li ntawd, rau qee lub cav diesel, muaj tshwm sim qhov feem ntau haum kev khiav haujlwm ntau. Tsis tas li ntawd, thaum lub cav diesel nquag ua kom nrawm dua, nres, thiab pib siv cov khoom tsis zoo ntawm lub xeev cov roj diesel. Tshwj xeeb tshaj yog thaum pib pib, Crankshaft ceev yog qhov tsawg, cov roj pepruel yog qhov siab, thiab nws yog qhov nyuaj rau kev sib txhuam cov npoo ntawm cov npoo ntoo rau.
Qhov kub siv nyob rau hauv ib puag ncig kuj tseem muaj kev cuam tshuam ntawm kev hnav thiab kua muag ntawm volvo generator poob lawm. Thaum qhov kub yog qhov siab, lub cav yog qhov dhau overheating ntawm lubricating roj yog tsawg, thiab hnav ntawm qhov chaw nce. Thaum qhov ntsuas kub qis, viscosity ntawm lubricating roj nce ntxiv, ua rau nws nyuaj pib lub cav diesel. Cov dej txias tsis tuaj yeem tswj qhov kub thiab txias thaum ua haujlwm, yog li nce kev hnav thiab corrosion ntawm qhov chaw. Thaum lub cav diesel pib ntawm tsawg kub, cov hnav yog hnyav dua.
Kev ua haujlwm kub ntawm lub tshuab hluav taws xob yog ib qho tseem ceeb cuam tshuam rau kev hnav ris tsho thiab kua muag ntawm cov cav diesel. Thaum siv, vim muaj cov kev txwv ntawm cov qauv tsim kom txias, hloov pauv hauv cov khoom ua haujlwm thiab kev hloov pauv kub, kev ua haujlwm kub ntawm cov roj diesel tau sib txawv heev. Kev xyaum tau qhia tias cov dej txias txias yog tswj tau ntawm 75 tsawg dua lossis sib npaug ntawm 85℃roj kub yog tswj roj nrog 75 tsawg dua los yog sib npaug ntawm 95 degree.
