Dab tsi yog daim ntawv thov ntawm titanium alloy hauv tsheb?
I. Qhov zoo ntawm titanium thiab titanium alloy
Qhov zoo ntawm titanium hlau: siab zog, lub teeb yuag, kub tsis kam, corrosion kuj. Modulus ntawm elasticity yog hais txog ib nrab ntawm cov hlau, tsis tshua muaj coefficient ntawm thermal expansion, txog 50% stainless hlau thiab txhuas, uas tsis yog-sib nqus, tsis tshua muaj thermal conductivity, corrosion-resistant, non-polluting rau ib puag ncig. Yog li ntawd, tsis yog tsuas yog kev lag luam aerospace thiab tshuaj lom neeg kev lag luam tau muaj ntau tus titanium, thiab raws li cov khoom siv tsheb tau ntev tau nyiam cov neeg nyiam. Lub tsheb titanium tuaj yeem txo qhov hnyav ntawm lub tsheb, txo cov roj noj, txhim kho kev ua haujlwm, txhim kho ib puag ncig thiab txo suab nrov.
II. Daim ntawv thov ntawm titanium alloy nyob rau hauv lub tsheb
1. Cav Txuas Qws
Lub cav txuas rods ua los ntawm titanium alloys tuaj yeem txo lub cav loj, txhim kho kev siv roj thiab txo cov pa tawm. Piv nrog cov hlau txuas, titanium txuas rods tuaj yeem txo qhov hnyav los ntawm 15% mus rau 20%. Daim ntawv thov ntawm titanium txuas rods yog thawj zaug pom nyob rau hauv lub tshiab Ferrari 3.5LV8 thiab Acura NSX cav nyob rau hauv ltalis. Cov khoom siv rau titanium txuas pas nrig feem ntau yog Ti-6Al-4V, Ti-10V-2Fe-3Al, Ti-3Al - 2.0V and Ti-4Al-4Mo-S n-0.5S i.
2. Cav Valves
Lub tsheb cav li qub ua los ntawm titanium alloy tsis tuaj yeem tsuas yog txo qhov zoo thiab txuas lub neej kev pab cuam, tab sis kuj txo cov roj noj thiab txhim kho kev cia siab ntawm lub tsheb. Titanium li qub piv nrog steel li qub, qhov zoo tuaj yeem raug txo los ntawm 30% mus rau 40%, lub cav txwv ceev tuaj yeem nce 20%.
3. Valve Caij Nplooj Ntoos Hlav
Lub zog siab thiab qaug zog ua haujlwm yog lub rooj zaum lub tog raj kheej yuav tsum muaj kev ua tau zoo ntawm titanium alloy rau kev kho cua sov hom alloy, tuaj yeem ua cov tshuaj tiv thaiv kev laus kom tau txais lub zog siab, cov ntaub ntawv tsim nyog ntau dua yog Ti - 15V {{1 }}Cr - 3Al - 3Sn.
4. Titanium Alloy Caij nplooj ntoos hlav
Titanium thiab nws cov alloys txheeb ze rau cov ntaub ntawv hlau muaj qhov qis dua ntawm elasticity, σs / E tus nqi yog qhov loj, haum rau kev tsim cov khoom siv elastic. Piv nrog rau steel tsheb springs, nyob rau hauv lub premise ntawm tib elastic ua hauj lwm, qhov siab ntawm titanium springs tsuas yog 40% ntawm steel springs, thiab qhov zoo tsuas yog 30% mus rau 40% ntawm steel springs, uas yog yooj yim rau tsim ntawm lub tsheb lub cev. . Tsis tas li ntawd, titanium alloy zoo heev qaug zog kev ua tau zoo thiab corrosion kuj tuaj yeem txhim kho lub neej kev pab cuam ntawm lub caij nplooj ntoos hlav.
5. Exhaust System thiab Muffler
Titanium yog siv nyob rau hauv ntau ntau nyob rau hauv lub pa system ntawm tsheb. Titanium tso tawm tshuab tuaj yeem txo qhov hnyav li ntawm 40% piv rau cov pa hluav taws xob. Titanium mufflers muaj ib tug loj ntawm 5 mus rau 6 kg, uas yog sib dua li stainless hlau thiab lwm yam mufflers. Cov kev hloov pauv muaj tib lub zog thiab ua rau lub tsheb nrawm dua, ua kom muaj zog thiab siv roj ntau dua. Lub titanium siv rau lub muffler tseem yog feem ntau industrially ntshiab titanium.
6. Lub Cev Ncej Tshooj
Txhawm rau txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm lub tsheb, kev txiav txim siab yuav tsum tau muab rau cov qauv tsim thiab kev tsim khoom, tshwj xeeb tshaj yog cov khoom siv hauv kev tsim khoom. Titanium yog ib qho khoom siv zoo heev rau lub cev ntas, tsis yog rau nws lub zog tshwj xeeb, tab sis kuj rau nws qhov zoo toughness.
7. Lwm yam Titanium Cheebtsam
Ntxiv rau cov khoom siv saum toj no, titanium kuj tseem siv rau hauv lub cav rocker caj npab, ncua kev kawm ntawv, lub cav piston pins, tsheb fasteners, lug ceev, tsheb qhov rooj protruding kab teeb, tsheb iav brackets, nres caliper pistons, pins, siab daim hlau, hloov khawm thiab automotive clutch phaj thiab lwm yam automotive qhov chaw.
