Titanium tso pa systemyog khoom plig rau lawv lub teeb yuag, lub zog, thiab tiv thaiv corrosion thiab kub. Txawm li cas los xij, txawm tias cov khoom siv qib siab no tuaj yeem tsim cov kab nrib pleb hauv qee yam mob. Kev nkag siab txog dab tsi ua rau titanium tso tawm kom tawg yog qhov tseem ceeb rau cov tuam txhab, cov neeg sib tw, thiab cov neeg nyiam uas xav ua kom muaj zog thiab ua haujlwm tau zoo.
1. Cov laj thawj tseem ceeb ntawm Titanium Exhaust Cracking
A. Thermal Cycling thiab qaug zog
Qhov kub hnyiab heevtshwm sim hauv cov pa tawm- cua sov sai thaum lub cav pib thiab khiav, tom qab ntawd txias thaum nws kaw.
Titanium nthuav dav thiab cog lusnrog kub hloov. Kev rov ua dua tuaj yeem ua rauthermal qaug zog, ua rau microcracks uas yuav loj hlob dhau sijhawm.
Khiav thiab haiv neeg sivaccelerates qhov no vim qhov kub thiab txias heev.
B. Kev them nyiaj yug tsis txaus thiab kev vibration
Tsis txaus mounting los yog bracingtso cai rau kev txav mus los lossis kev co.
Kev vibration ntawm lub cav los yog txoj kevtuaj yeem ua rau muaj kev ntxhov siab ntawm welds, pob qij txha, lossis khoov, tshwj xeeb tshaj yog nyob rau hauv lub teeb yuag.
Resonancentawm qee RPMs tuaj yeem ua rau muaj kev ntxhov siab ntawm cov ntsiab lus tsis muaj zog.
C. Welding tsis zoo lossis Fabrication
Titanium vuam xav tau kev txawjthiab tswj, inert ib puag ncig (xws li, argon shielding).
Cov kab mob (oxygen, nitrogen, hydrogen)nyob rau hauv qhov chaw weld tuaj yeem ua rau titanium nkig, ua rau cov kab nrib pleb tuaj yeem tshwm sim ntawm weld seams.
Nyias- phab ntsa tubingtshwj xeeb tshaj yog yooj yim yog hais tias weld nkag los yog tsis zoo.
D. Tsim kev tsis haum thiab kev ntxhov siab
Ntws khoov, nruj radii, lossis hloov pauv saituaj yeem mloog zoo rau kev ntxhov siab thiab ua raws li qhov chaw pib tawg.
Cov ntu tsis txhawb nqalos yog kev sib raug zoo tsis zoo tuaj yeem ntxiv cov neeg kho tshuab kev ntxhov siab.
E. Overheating lossis overheating
Kev ua haujlwm ruaj khov ntawm qhov cua txias heev(khiav los yog siv turbocharged) tuaj yeem degrade titanium's microstructure.
Xiav / liab doog discolorationqhia tau hais tias raug tshav kub tab sis, yog tias ntau dhau, nws yuav qhia tau tias cov khoom raug thawb dhau nws qhov kev txwv, nce brittleness.
F. Kev puas tsuaj
Txoj kev khib nyiab, hauv qab tawm, los yog tiv tauj nrog curbstuaj yeem tsim cov dents lossis microcracks uas nthuav tawm nrog kev vibration thiab thermal cycling.
2. Cov lus xaus
| Ua rau | Kev piav qhia/Mechanism | Kev Tiv Thaiv / Tsawg |
|---|---|---|
| Thermal Cycling | Expansion/contraction ua rau qaug zog | Tso cai rau kev txav, siv cov pob qij txha |
| Kev vibration / Kev them nyiaj tsis txaus | Kev txav mus los - ua rau muaj kev ntxhov siab, tshwj xeeb tshaj yog nyob rau welds | Zoo mounting, vibration dampers |
| Welding tsis zoo | Cov kab mob sib kis lossis cov txheej txheem tsis raug | Kev tshaj lij, inert-gas vuam |
| Tsim Flaws | Nyuaj khoov, kev nyuaj siab risers | Smooth hloov, optimized tsim |
| Kub kub | Ntev ntev siab ua kom brittleness | Thaum tshav kub kub shields, airflow kom zoo |
| Kev puas tsuaj | Lub cev dents, tawg los ntawm cov khib nyiab los yog cuam tshuam | Ua tib zoo routing, skid daim hlau |
3. Kev Paub Txog Kev Lag Luam
Sib tw thiab taug kev tsheb kauj vab:Ntau dua rau kev tawg vim ntau zaus, huab cua kub mus thiab ntau dua kev co.
Tom qab kev muag khoom systems:Thinner phab ntsa rau qhov hnyav txuag, tab sis ntau rhiab heev rau kev txhim kho thiab kev txij nkawm.
OEM systems:Feem ntau siv cov phab ntsa tuab thiab kev tsim qauv tsim kom muaj zog dua.
4. Cov kev coj ua zoo tshaj plaws los tiv thaiv kev tawg
Xyuas kom tag nrho cov hangers thiab mounts muaj kev ruaj ntseg thiab siv vibration- cais cov ntaub ntawv.
Muaj cov khoom siv hluav taws xob tsim thiab welded los ntawm cov kws tshaj lij uas siv cov khoom siv tiv thaiv zoo.
Zam kev khoov ntse thiab hloov pauv sai ntawm cov yeeb nkab txoj kab uas hla.
Tshawb xyuas tsis tu ncua kom tsis muaj xim, tawg, lossis cov cim qhia txog kev cuam tshuam.
Cia lub tso cua txias kom txias; zam kom txias sai sai (piv txwv li, cov tshuaj tsuag dej tom qab siv khiav).
