Heavy equipment engine fault diagnostics

Svoevremennaya diagnostika neispravnostey engine pozvolyaet vyyavit problemy na ranney stadiand and predotvratit sereznye polomki. V etom rukovodstve my rassmotrim osnovnye priznaki neispravnostey engine spetstekhniki and metody ikh diagnostiki.

Osnovnye priznaki neispravnostey engine

1. Problemy s zapuskom

Esli engine ne zapuskaetsya ili zapuskaetsya s trudom, vozmozhnye prichiny:

• Razryazhennyy akkumulyator — proverte napryazhenie akkumulyatora
• Neispravnyy starter — proverte rabotu startera
• Problemy s toplivnoy sistemoy — proverte fuel filter and nasos
• Problemy s sistemoy zazhiganiya — proverte svechi and sistemu zazhiganiya

2. Snizhenie moshchnosti

Esli engine teryaet moshchnost, proverte:

• air filter — zagryaznennyy filter snizhaet moshchnost
• fuel filter — zasorennyy filter ogranichivaet podachu topliva
• Turbonadduv — proverte rabotu turbiny
• system okhlazhdeniya — peregrev snizhaet effektivnost

3. Povyshennyy raskhod topliva

Uvelichenie raskhoda topliva mozhet byt vyzvano:

• Nepravilnoy regulirovkoy toplivnoy systems
• Iznosom forsunok
• Problemami s sistemoy okhlazhdeniya
• Nizkim kachestvom topliva

4. Neobychnye zvuki

Razlichnye zvuki mogut ukazyvat na problemy:

• Stuk — mozhet ukazyvat na iznos podshipnikov ili porshnevoy gruppy
• Svist — vozmozhna utechka vozdukha ili problemy s turbinoy
• Skrip — mozhet byt svyazan s remnyami ili podshipnikami

5. Dym iz vykhlopnoy truby

Tsvet dyma mozhet mnogoe rasskazat o sostoyaniand engine:

• Chernyy dym — pereobogashchenie toplivnoy smesi, problemy s forsunkami
• Belyy dym — popadanie okhlazhdayushchey zhidkosti v cylinders
• Siniy dym — sgoranie motornogo oils, iznos porshnevykh kolets

Metody diagnostiki

Visual inspection

Nachnite s vizualnogo osmotra:

• Proverte uroven and sostoyanie oils

• Osmotrite air and fuel filters

Diagnostika s pomoshchyu priborov

Ispolzuyte diagnosticheskoe equipment:

• Skaner oshibok — dlya chteniya kodov neispravnostey
• Manometr — dlya proverki davleniya oils and topliva
• Kompressometr — dlya proverki kompressiand v tsilindrakh
• Multimetr — dlya proverki elektricheskikh systems

Analiz oils

Laboratory analysis oils pozvolyaet vyyavit:

• Iznos detaley engine
• Popadanie okhlazhdayushchey zhidkosti v oil
• Zagryaznenie oils toplivom
• Sostoyanie prisadok v masle

My predlagaem uslugi analiza masel and technical fluids dlya diagnostiki sostoyaniya your equipment.
