Yi kuskuren injin zai iya tsayawa "sabon makini 1/3" kawai? —— abokan ingginia mai shekara 30 yana da labarin mai tsawo mai yiwuwa wanda ya koyar da ku yin gyara girma ta hanyar yin gyara injin 80%!6 kayan aiki masu mahimmanci da damfassan 4 don sauƙaƙe duka uku da biyu

Wasu abokan aikin na ke nemi:
"Shi kuskuren injin zai iya tsayawa wajen sakawa daya kawai na sabon?"
Amma iri naka - a wadannan alamar da aka yi maintenance, injin zai iya samun tsawon rawar sabon makini bayan gyara girma.
Wandan ke gudanar da tsawon rawar ne: amfanin kayan aiki mara amfani, albishin da ba shi da kyau, amfanin kayan aiki mara kyau, da ƙaramin dubawa da karkashin.

Daga binciken na shekaru da manyan shekaru, na kula da kayan aiki masu mahimmanci a daban, domin ma'ajin abokan aikin da suka buƙatar saukewa amma sun so injin ya tsaya sosai.

 

I. Alamar da ake buƙata don gyara girma

Gyara girman injin ba "rufe, canza, da saita" bane, kuma dole ne a yi shi cikin wasan kimiyya mai mahimmanci wanda yana da wadannan halaye:

• Albishin saitin saituna
• Matsar da kayan sauyawa
• Takarda na gwaji, takarda na gurji
• Albarkatu masu dacewa (mita na girma na wiyar, mita na koma, mita na alfu, da sauransu)
• Mai karfafa mai amfani da alhakin guduma

Idan baka yi wadannan sharuddan, babu ingancin yawa.
Kamar yadda ya kamata, ba za a iya kontin kalubale na kayan aikin daidaita, kuma kayan aikin da ke mahimmanci ba za a amta su ba!

 

II. Abubuwan muhimman gudumawar guduma

1. Sauna dole ne taushe (babu zama ta tafiye)

Wadannan yankuna dole ne a sauya:

• Hanyar hawa, hanyar abura
• Crankshafts, joints, interior na body
• Dukko dukko pipelines
• System na lubrication
  Kuma gujuba ingancin wear, koma shawarar replacement kuma rika shi.

Munabiyoyin muhimmi:

• Cap bolts, rod bolts, da shaft bolts suna "plastic deformation bolts" kuma suna da huduwar adadin lokuta da za a iya amfani da su kuma dole ne a canza su idan ba za a iya tabbatar da su bane.
• Dukkanin bolts da ke bukata torque dole ne a yadda ake nuna darajar, kuma ba dole ne a "feeling"!
  Nauyi dai na yi lafiya da waɗan tare da bolts na crankshaft weighting block suna barayen saboda torque ya fi, wanda ya samu damage direkta ga body - misalin "non-conformity."

 

2. Tsauraran wurin assembly yana nufin abokurwa

Wannan shine tunani mai kuruci:

• Taliyar mai aikin wakili ta ke da dakin manyan ruwa da raggi a wurin a rani, kuma tsarin aikin ya kasance mai hankali, kuma an tura injin bayan da ma labarin ojo iri de - dalilin shine raggi!
• Gwargwadun mi ta babu waɗannan nau'ikan kuskure zuwa baya labarai, saboda kai tsaye zuwa cikin nihimta, kamar yadda ke kasancewa tsokace.

Hanyoyin amfani:

• Yi amfani da zanen gaskiya don sassa (zaman da ke wadanda suke iya samunsa).
• Lokacin da yake da kyau, sassa farin gari ta hannu da ruwa.
• A rani, kirkiri garuruwa mai sauƙi don kula da humuditi daga raggi.
• Duk wadannan hudu na goyan, yanayin zuwa gaskiya, da sauran abubuwan masu mahimmanci suna bukatar lokaci don aiki cikin albishin mai nihimta.

Wannan ita ce takamfe mai adalci amma mai amfani mai zurfi "tsarin al'ada".

 

3. Kima da kiyasin nau'ika da kiyasin shigarwar waje

Zai kamata a kimi waɗannan abubuwan masu mahimmanci masu mahimmanci:

• Tsarin axis na curve, tsarin radial / axial bending
• Samun farko a cikin wazin girma na joint assembly
• Crankshaft + tsarin balance na flying wheel
• Farko a tsakiyar main bearing shell da connecting rod shell
• Farko na karo da side gap na piston ring
• Gudanrar oil pump (Kwafinta canza shi)

Alamar muhimmanci na nukarin lubrication system:

• Duba dama na giniyar oil filter ya fara pressure
• Tabbata cewa piston yana kuskuren nozzles daidai.
• Duk indaɗan oil dole ne a siyan su da kuma an lubricate su zuwa kai

Bayani mai tsada:

• Kada ka yi wani aikin “sauran shiga” baki.
  An kirkirar falgan silinda ta " laser quenching " don nuna tushen, sai kuma farkon ring din piston ya ruwa sosai – wani abubuwan da suka dawo friction pair ba su dawo ba.

 

4. Zaman lafiya masu takwasawa suna bukatar atunwa ga "farko mai kuwi".

Wasu abubuwan masu yawa akan zaman lafiya masu takwasawa:

• Farko mai tsawawa tsakanin shaft na rocker da rocker pore → pressure na juzuwa mara standard
• Zinayi na jet casing → Kuskure waƙaƙe
• Harbargen ruwa da harbargen maiɗa suna kiyaye → Kwada su a canza sosai
• Dabarri mai zurfi na maiɗa → Dole ne a gano dalilin sa kafin ka ci gaba da amfani

Sani: Wani gyara girma ita ce "gyara sosai," sai kuma wani bauta ita ce "canza ba tare da hada da standard ba."
Alajiji masu yawa suna da sharuddan testowa masu iyaka, kuma yake da muhimmanci a kawo hankali don karɓa abin da zai haɗa waƙaƙe.

Wani dora mai muhimmanci:
Duk abubuwan da aka cire dole ne a marka su, abubuwan da aka amfani da su dole ne a sake sanya bisa wurinsu, abubuwan da bai amfani da su ba dole ne a futuwa komai, kuma bai zama iya ƙunya su ba.

 

5. Maiɗa da kuma binciken farko bayan wani gyara girma

Awanni 50 bayan gyara ita ce "karni mai waƙaƙe" kuma dole ne a kawo hankali zuwa shi:

• har zuwa ta ruwa
• Dabarri na maiɗa
• Zube mai zurfi
• Anjiya runzuwa, anjiya runzuwa
• Hali mai rura

Duk wani matsar da ya dole a wara kuma a buce shi kusan lokaci

 

6. Ya kamata a sake tsaro shi kari uku ne 50 awa bayan gyara

Yana haɗawa:

• Dauke anjiya
• Sake yi amfani da fiter
• Dubuta don kuturu
• Ka duba tsawon ruwa da dabin anjiya

Wannan hankali manya babu shi masu siyan gargajiya, wasu lokuta yana samunun matsalolin injin waɗanda suka dauki 200 awa.

 

III. Wasu tambayoyin na'ura (muhimmiyar kyauta)

1. Nau'in gas kara za ta iya cire gurji → babban mutuwa ba ya dali sosai.
2. Hawan da aka sarrafa ke sama daya zuwa tafarki mai tsinkaya → abubuwan kayan cin abinci sun yi sallama, kuma mesin yana tafi hankali zuwa sauya.
3. Tame ce a sarrafa girman ruwa: mesin yanzu yana da wani yankin ruwa, sai dai idan baku shi, zai sami zurfi.
4. Duba girman abinci da ruwa a mesinun sarduna itace shine ayyukan kowane rana don masu amfani.
5. Yi katsewa a tallafin ilmin fahimta yayin da ake bukata, sai dai zaka sami karfin kuskuren bayani.

 

bayan fikir

Mutuwar mesin ba abokin teknikal bane, amma:

• Shin ana bucewa su bisa fasaha?
• Shin akwai mahimmacin goyon gano?
• Shin za ka yarda ka sauye kayan aiki masu mahimmanci?
• Shin tayi tabbata cikakken sauya da misali
• Shin an kama sarrafawa da gyara-maki?
• Shin an yi amfani da zurfi da kayan gyara-maki masu iko?

Idan an yi waɗannan duk, zai iya canza maƙina zuwa ga yadda ya kasance a baya 80 % na rayuwa ba shi ikwaa.
