Kev tshawb fawb ntawm corrugated stainless hlau yeeb nkab: thermal expansion thiab mertaction

Lub hauv paus rau phau ntawv

Corrugated Stainless hlau kav yog dav siv hauv ntau yam kev lag luam, los ntawm cov kav dej zawv thiab hVAC thiab cov txheej txheem kev lag luam. Ib qho ntawm cov ntsiab lus tseem ceeb uas cov kws tsim qauv thiab cov neeg tsim qauv yuav tsum xav txog thaum cov kav dej yog lawv tus cwjpwm nthuav dav thiab kev cog lus tshwj xeeb. To taub qab qhov tshwm sim no tseem ceeb heev rau kev ua haujlwm kom nyab xeeb thiab siv tau ntawm cov kav hlau tsis huv.

Cov hauv paus ntawm kev nthuav dav thiab kev cog lus

Molecular piav

Nyob rau theem molecular, thermal expansion thiab condaction tshwm sim vim qhov kev hloov pauv ntawm lub zog ntawm atomet. Thaum lub corrugated stainless hlau yeeb nkab yog rhuab, cov atoms nyob rau hauv stainless - cov khoom siv steel qub thiab pib tshee ntau npaum li cas. Qhov kev co no nce ntxiv ua rau cov atoms txav me ntsis ntxiv sib nrug sib nrug sib nrug, ua rau muaj kev nthuav dav ntawm cov khoom ntawm macroscopic. Hloov siab, thaum cov yeeb nkab txias, cov atoms poob lub zog ua kom zoo, lawv txo qis, thiab lawv txav mus ze ua ke, ua rau muaj kev cog lus.

Coefficient ntawm thermal expansion (CTE)

Cov coeffic kev nthuav dav yog ib qho kev ntsuas ntawm ntau npaum li cas cov khoom siv nthuav dav lossis sib cog lus nrog kev hloov pauv kub. Rau corrugated stainless hlau kav, CTE yog tsawg dua piv rau qee cov ntaub ntawv, tab sis nws tseem muaj qhov tseem ceeb txaus kom muaj kev txiav txim siab hauv kev tsim qauv engineering. CTE ntawm stainless hlau feem ntau yog li ntawm txog {0}}}}}}, degree, raws li qib ntawm stainless hlau. Qhov no txhais tau tias rau txhua txhua 1 kev hloov pauv hauv qhov kub,}}} cov yeeb nkab yuav nthuav tawm lossis sib cog lus los ntawm ib qho feem ntawm millimeter. Piv txwv li, yog tias CTE yog 15 x 10⁻⁶ / degree,}} Cov yeeb nkab - ntev xaim yuav nthuav dav los ntawm 0.015 mm rau txhua 1 degree hloov hauv qhov kub.

Qhov cuam tshuam rau kev nthuav dav thiab kev cog lus hauv corrugated stainless hlau kav

Qib ntawm Stainless Hlau

Cov qhab nia sib txawv ntawm cov hlau tsis muaj stainless muaj cov coeffic me ntsis ntawm kev nthuav dav thermal. Raws li tau hais ua ntej, cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau stainless, uas txawv ntawm cov qib, cuam tshuam nws CTE. Piv txwv li, stainless hlau qib nrog siab dua li tsib xee cov ntsiab lus feem ntau muaj CTE me ntsis piv rau cov uas muaj cov ntsiab lus tsis muaj npe tsawg dua. Hauv cov ntawv thov uas ntsuas kev nthuav dav ntawm kev nthuav dav ntawm thermal yog qhov tseem ceeb, kev xaiv ntawm stainless - qib steel tuaj yeem yog qhov kev txiav txim siab tseem ceeb.

Qhov ntsuas kub ntau

Qhov ntau ntawm cov cua sov nthuav dav thiab maub los yog ncaj ncaj qha rau qhov kub ntau yam cov yeeb nkab muaj rau. Hauv kev siv cov ntawv thov uas cov kav dej ntev yuav raug rau cov nroj tsuag kub heev, cov qib txias tuaj yeem ua rau muaj ntau txheej txheem, cov hluav taws xob nthuav dav thiab kev cog lus tuaj yeem ua tau ntau. Nyob rau hauv kev sib piv, nyob rau hauv ib lub qhov dej ntws nrog cov dej khov kho nrog cov dej me me ntawm cov kav dej kub thiab cov kuab cua txias, cov kav dej yog tsawg dua tab sis tseem yuav tau suav rau.

Yeeb Nkab Geometry Thiab Installation

Lub corrugated tsim ntawm cov yeeb nkab tseem ua lub luag haujlwm hauv nws qhov kev nthuav dav kub thiab kev coj tus cwj pwm. Txoj kev corrugations tuaj yeem muab qee qhov hloov qee yam, tso cai rau cov yeeb nkab kom nthuav dav thiab cog lus ntau dua piv rau cov yeeb nkab du - walled yeeb nkab. Txawm li cas los xij, txoj kev uas cov yeeb nkab tau teeb tsa tuaj yeem txhim kho lossis txwv qhov hloov no. Yog tias cov yeeb nkab yog nruj ruaj khov ntawm ob qho kawg tsis muaj kev nthuav dav, kev cog lus thermal tuaj yeem yog qhov kev puas tsuaj loj, ua rau muaj kev puas tsuaj los yog deformation.

Qhov tshwm sim ntawm unaccounted thermal expansion thiab mertaction

NEEG KHO TSHUAB KEV LUAJ THIAB TSIS TAU

Thaum thermal expansion thiab mortaction tsis tau suav rau hauv tus qauv thiab teeb tsa ntawm corrugated stainless - cov kav hlau muaj kev ntxhov siab tuaj yeem tsim tsa hauv cov yeeb nkab. Cov kev ntxhov siab no tuaj yeem ua rau cov yeeb nkab los khoov, warp, lossis txawm tawg. Nyob rau hauv ib tug piping system uas thauj cov dej siab - kua kom siab siab, uas tuaj yeem ua rau muaj hluav taws kub, uas tuaj yeem ua rau hluav taws kub, uas tuaj yeem ua rau hluav taws kub, muaj feem xyuam rau hluav taws, lossis cov khoom tawg.

To ntawm pob qij txha

Thermal Zog tuaj yeem cuam tshuam rau kev sab nrauv cov pob qij txha. Yog hais tias kev nthuav dav thiab kev txhawb zog ua rau cov pob qij txha txav lossis cais me ntsis, nws tuaj yeem ua rau toast. Hauv cov kav dej kav dej, piv txwv li, ib qho xau me me ntawm kev sib koom ua ke vim cua hlob tuaj yeem maj mam ua kom muaj kev puas tsuaj rau cov qauv ib puag ncig dhau sijhawm. Hauv kev siv cov ntawv thov, to ntawm cov pob qij txha tuaj yeem ua rau muaj txiaj ntsig zoo ntawm cov kua lossis roj av, txo cov txheej txheem kev nyab xeeb ntawm kev nyab xeeb.

Cov tswv yim kom haum raws li kev nthuav dav kub thiab cog lus

Cov pob qij txha nthuav dav

Ib qho ntawm cov kev tshwm sim feem ntau kom haum rau kev nthuav dav thiab kev cog lus hauv corrugated stainless - steel kav yog los ntawm kev siv ntawm kev nthuav dav. Cov pob qij txha nthuav dav yog cov khoom siv sib txuam uas tau teeb tsa ntawm kev sib nrug ntawm cov raj xa dej. Lawv tuaj yeem nqus lub thermal txav ntawm cov yeeb nkab los ntawm kev nthuav dav lossis sib cog lus lawv tus kheej. Muaj ntau hom sib txawv ntawm cov pob qij txha, xws li fwj pwm nthuav dav, uas yog ua los ntawm cov khoom siv nyias, uas tuaj yeem ncab thiab zaws kom haum rau cov yeeb nkab

Saj zawg zog cov yeeb nkab yeeb

Lwm lub tswv yim yog siv cov ntu hloov tau ntawm corrugated stainless - cov yeeb nkab steel. Lub ntuj yooj ntawm kev tsim qauv corrugated tuaj yeem hloov kho ntxiv los ntawm kev siv cov yeeb nkab uas yoog raws cov yeeb nkab uas muaj qhov tshwm sim. Cov ntu hloov tau tuaj yeem khoov thiab ntswj los nqus cov khoom nthuav dav thiab kev sib zog tsis muaj kev ntxhov siab ntau dhau. Hauv qee cov kev siv, coiled ntu ntawm corrugated stainless - cov yeeb nkab steel siv, uas tuaj yeem muab cov kev hloov pauv kub ntxiv kom haum.

Cov Hluav Taws Xob Tsim Nyog thiab Anchoring

Qhov txheej txheem ntawm cov kav dej thiab txoj kev cov kav dej yog anchored kuj ua lub luag haujlwm hauv kev tswj hwm thermal thiab consaction. Los ntawm kev tsim qauv txheej txheem uas tso cai rau cov kav dej kom nthuav dav thiab sib cog lus hauv ib txoj kev tswj hwm, kev ntxhov siab tuaj yeem txo qis. Anchors thiab cov kev qhia tuaj yeem muab cov leeg tso rau kom coj ncaj qha rau kev txav ntawm cov kav dej thiab tiv thaiv kev puas yog khoov lossis buckling. Piv txwv li, nyob rau hauv ntev - khiav raj dej, anchors tuaj yeem ntsia tau ntawm cov kab ke sib txuas, thiab cov yeeb nkab txav dawb rau hauv cov kev xav tau zoo thiab kev cog lus.
