2. Karya

1) Features. Zoben fistan na farko ya karye kuma an lalata zoben zoben piston; akwai alamomin jakunkuna a saman aiki na waje na zoben piston da ɓangaren sama na Silinda; siket ɗin piston da ɓangaren sama na silinda suna narkewa kuma suna sawa; karaya yakan faru a bangarorin biyu na budewa. Wurin nunawa.

2) Dalilai. Dalilin karayar zoben piston kai tsaye shine rashin amfani ko kiyaye injin. Babban abubuwan da ke tasiri sune: injin dizal yana aiki a ƙarƙashin zafi na dogon lokaci, yana haifar da zoben piston don matsewa; Dankowar man mai da ake amfani da shi ya yi yawa; zaɓi na zoben piston ba daidai ba ne ko hanyar shigarwa ba daidai ba ne, wanda ke haifar da damuwa da damuwa na zoben piston; fistan da silinda Daidaiton injin dizal ya yi ƙanƙanta sosai; injin dizal yana aiki a ƙarƙashin yanayin lalata na dogon lokaci.

3. Zobe mai ɗaki

1) Features. Akwai mai yawa sludge, carbon adibas da colloidal adibas a kan piston zobe da piston zobe tsagi; saman aiki na waje na zoben piston yana ba da haske mai gogewa, kuma akwai ɓarna mai zurfi mai zurfi; elasticity na zoben piston yana da rauni.

2) Dalilai. Dalilin kai tsaye na zoben mannewa shine cewa zoben piston yana haɗe da sludge da ajiyar carbon, kuma zoben piston da silinda sun lalace. Babban abubuwan da ke haifar da tasiri sune: mummunar nakasar zafi na zoben piston da Silinda, ƙananan koma baya da koma baya na zoben piston, sa zoben ya makale a cikin ramin zobe kuma ya kasa motsawa; injin dizal yana da zafi fiye da kima ko kuma na dogon lokaci da yawa, wanda ke haifar da mai ya haifar da colloid mai zafi; Rashin ingancin man mai; rashin ingancin allurar mai na mai mai; rashin aikin yi na na'urar samun iska na crankcase, haifar da matsananciyar matsananciyar matsananciyar matsananciyar matsananciyar wahala ko ƙarancin iska na Silinda, haifar da ƙarar mai; zaɓi mara ma'ana na silinda liners ko hanyoyin da ba daidai ba latsa nakasawa da sauransu.

4. Bangaren lalacewa

1) Features. Fuskokin ƙarshe na sama da na ƙasa na zoben piston da tsagi na zobe suna da ƙananan lalacewa, rashin daidaituwa ko rashin daidaituwa a saman kewaye; akwai tsinkaya na tsayin daka akan farfajiyar aiki na waje na zoben piston saboda lalacewa ta m; akwai busa a zoben fistan da saman alamar fistan.

2) Dalilai. Dalilin kai tsaye na rashin son zuciya na zoben piston shine saboda kuskuren matsayi na piston a cikin silinda. Babban abubuwan da ke tasiri su ne: rashin isasshen aiki na sabon injin ko injin dizal bayan an sake gyarawa; nakasar thermal na layin silinda da matsayi mara kyau bayan an shigar da silinda a cikin shingen Silinda; lankwasawa ko karkatar da sandar haɗi; wuce kima crankshaft axial yarda, da dai sauransu.


5. Scratches a kan aikin aiki

1) Features. Akwai tsagi masu tsayi a gefe ɗaya na zoben piston ko a saman aiki mai kewaye; kwasfa na ƙarfe ko manyan-ɓangarorin yanki akan fuskar lamba; aiki saman scratches da m zobba sau da yawa faruwa a lokaci guda.

2) Dalilai. Dalilin kai tsaye na tayar da zobe na piston shine saboda lalata fim ɗin mai mai mai a tsakanin zoben piston da silinda. Babban abubuwan da ke haifar da tasiri sune: madaidaicin yarda tsakanin fistan da silinda ya yi ƙanƙanta; Hanyar haɗa zoben piston ba daidai ba ne ko kuma an matsa bakin zobe ko a shimfiɗa yadda ake so yayin taron don haifar da nakasawa; Hanyar haɗuwa da silinda ko ƙarar kan silinda ba daidai ba ne, yana haifar da silinda ta lalace; Yin aiki na dogon lokaci na injin dizal a ƙarƙashin yanayin zafi mai zafi yana sa fim ɗin mai mai mai ya karye; rashin isassun man mai ko gurbataccen yanayi, da dai sauransu.
