Dab tsi yog kev siv lub tsheb turbocharger liner
Lub luag haujlwm tseem ceeb ntawm lub tsheb turbocharger yog ua kom lub cev muaj zog, yog li ua kom lub zog tso zis thiab lub zog ntawm lub cav, kom lub tsheb tau txais lub zog ntau dua. Tshwj xeeb, lub turbocharger siv cov pa hluav taws xob los ntawm lub cav los tsav lub compressor, thiab compresses cua mus rau hauv cov kav dej kom tsawg, ua kom cov khoom noj kom tsawg, ua rau lub cav hlawv roj ntau, yog li ua kom lub zog tso zis ntau ntxiv.
Yuav ua li cas lub turbocharger ua haujlwm
Turbocharger feem ntau yog tsim los ntawm ob ntu: turbine thiab compressor. Thaum lub cav ua haujlwm, cov pa pa tawm tawm los ntawm cov yeeb nkab tso tawm, thawb lub turbine kom tig. Kev sib hloov ntawm lub turbine tsav lub compressor thiab compresses huab cua mus rau hauv cov yeeb nkab intake, yog li ua rau kom tau txais siab thiab txhim kho cov combustion efficiency thiab lub zog tso zis.
Qhov zoo thiab qhov tsis zoo ntawm turbochargers
Qhov zoo:
Lub zog tso zis ntau zog: Turbochargers muaj peev xwm ua kom cov cua nkag mus, tso cai rau lub cav ua kom muaj zog thiab lub zog ntau dua rau tib qhov kev hloov pauv.
Kev txhim kho roj kev lag luam: Cov cav nrog turbocharged hlawv zoo dua, feem ntau txuag tau 3%-5% roj, thiab muaj kev ntseeg siab, zoo sib xws thiab cov lus teb ib ntus.
Hloov mus rau qhov siab siab: turbocharger tuaj yeem ua rau lub cav muaj zog tso tawm ntawm qhov siab siab, los daws qhov teeb meem ntawm cov pa nyias nyias ntawm qhov siab.
Disadvantages:
Turbine hysteresis : Vim lub inertia ntawm lub turbine thiab nruab nrab bearing, thaum cov pa pa dheev nce, lub turbine ceev yuav tsis nce tam sim ntawd, ua rau lub hwj chim tso zis hysteresis.
Cov nyhuv qis qis tsis zoo: nyob rau hauv cov ntaub ntawv ntawm kev ceev ceev lossis tsheb khiav ceev, cov nyhuv ntawm turbocharger tsis pom tseeb, txawm tias zoo dua li lub tshuab nqus tsev.
Automotive turbochargers yog tsim los ntawm cov khoom sib txawv xws li lub log, bearings, plhaub thiab impellers. Cov log feem ntau yog ua los ntawm cov khoom siv superalloy, xws li Inconel, Waspaloy, thiab lwm yam, kom ua tau raws li qhov xav tau ntawm qhov kub thiab txias.
Bearings feem ntau yog ua los ntawm cermet thiab lwm yam ntaub ntawv los txhim kho hnav thiab corrosion kuj.
Rau lub plhaub, lub plhaub compressor feem ntau yog aluminium alloy lossis magnesium alloy kom txo qhov hnyav thiab txhim kho kev ua haujlwm, thaum lub plhaub turbine feem ntau yog cam khwb cia hlau.
Lub impeller thiab ncej yog tsuas yog ua los ntawm cov hlau, tshwj xeeb tshaj yog cov compressor impeller feem ntau siv superalloy, uas muaj zoo heev kub oxidation kuj, lub zog thiab corrosion kuj.
Cov khoom ntawm qhov sib txawv thiab lawv txoj haujlwm
log hub : siv cov khoom siv kub kub, xws li Inconel, Waspaloy, thiab lwm yam, kom ua tau raws li qhov yuav tsum tau muaj ntawm qhov kub thiab txias.
bearing : feem ntau yog siv cov hlau ceramic thiab lwm yam ntaub ntawv los txhim kho hnav thiab corrosion kuj.
plhaub:
compressor plhaub: feem ntau aluminium alloy lossis magnesium alloy, kom txo qhov hnyav thiab txhim kho kev ua haujlwm.
turbine plhaub: feem ntau cam khwb cia hlau khoom.
impellers thiab shafts : feem ntau steel, tshwj xeeb tshaj yog compressor impellers feem ntau siv superalloy, no alloy muaj zoo heev kub oxidation kuj, lub zog thiab corrosion kuj.
Influencing yam ntawm kev xaiv cov khoom
Kev xaiv cov khoom siv turbocharger feem ntau suav nrog cov hauv qab no:
Qhov kub thiab txias siab: qhov kub thiab txias ntawm lub turbocharger yog siab, thiab nws yog ib qho tsim nyog yuav tau xaiv cov khoom uas muaj qhov kub thiab txias thiab kub siab.
hnav tsis kam : cov khoom hnyav yuav tsum muaj qee yam hnav tsis kam los txhim kho lub neej kev pabcuam.
mechanical zog: cov ntaub ntawv yuav tsum muaj lub zog txaus thiab toughness kom tau raws li qhov xav tau ntawm kev ua haujlwm siab.
