Cov khoom siv nthuav dav nyob rau hauv kev tsim kho kev tsim kho feem ntau suav nrog cov hauv qab no:
Corrugated Kev nthuav dav
Axial billows nthuav kev sib koom ua ke: nws yog tsuas yog siv los them rau cov raj xa pa Axial. Nws yog feem ntau siv nyob rau hauv cov dej ua dej thiab cov kav dej ntws tawm thiab cov kav dej hvac. Piv txwv li, nyob rau hauv cov dej kub tso cov kav dej tsis pub dhau cov tsev, vim tias cov roj ntsha ua rau cov kav dej ua ke tuaj yeem ua rau cov pob qij txha nthuav dav tuaj yeem nqus tau qhov kev hloov pauv no. Nws cov qauv yeeb yam yog tias cov yeeb nkab corrugated yog cov cylindrical nyob rau hauv cov duab, thiab kev them nyiaj kho mob raug them ntau yog feem ntau raws li cov yeeb nkab.
Transverse corrugated sib koom ua ke: hom kev nthuav dav no tuaj yeem them nyiaj rau cov raj xa rov qab. Nws yog siv nyob rau ntawm txoj kev khoov ntawm lub tuam txhab tsim lub tsev lossis qhov uas nws tau ua rau cov rog tom qab. Piv txwv li, thaum cov kav dej ntws tawm hauv lub tsev tom qab tsis sib xws ntawm lub hauv paus, qhov kev hloov pauv ntawm kev sib koom tes sib txuas lus zoo thiab tiv thaiv cov yeeb nkab puas zoo. Nws lub ntsej muag tuaj yeem yauv mus ua kev tawm tsam kom yoog raws li kev hloov chaw thaum raug rau cov tub sab tom qab.
Angular corrugated expansion sib koom ua ke: nws yog qhov haum rau them nyiaj ntawm lub rajmular qhov chaw xa dej Hauv kev tsim cov raj raj piping, nws tuaj yeem siv thaum lub kaum sab xis ntawm cov kav dej hloov vim kev teeb tsa lub tsev thiab lwm yam. Piv txwv li, nyob rau hauv cov piping system ntawm lub tsev kab hlau rhuav phab ntsa, vim lub phab ntsa me me ntawm phab ntsa, cov kav dej sib txuas nrog nws yuav yeblili tawg. Angular corrugated expansion pob qij txha tuaj yeem ua tau lub luag haujlwm them nyiaj hauv qhov no. Nws cov neeg tsis tuaj yeem tsim kom muaj kev sib txuas ntawm lub kaum ntawm lub axis kom yoog raws li kev hloov chaw.
Lub tes tsho expansion sib koom
Lub tes tsho expansion sib koom tes yog tsim ntawm lub tes tsho sab hauv thiab lub tes tsho sab nraud. Nws them nyiaj rau cov kab laum Axial ntawm cov raj xa dej los ntawm cov kwv tij swb ntawm sab hauv thiab sab tes tsho. Nws yog siv nyob rau hauv cov khoom siv dej thiab cov kav dej ntws tawm ntawm cov tsev thiab qee qhov kev them nyiaj rau kev them nyiaj tsis tshwj xeeb. Nws cov txiaj ntsig yog cov qauv yooj yim, tus nqi qis thiab muaj peev xwm tiv taus ib qho kev ua kom muaj axial thrust. Piv txwv li, nyob rau hauv cov chaw dej sab nraum zoov thiab dej ntws tawm ntawm qee cov tsev me me, tau them nyiaj rau cov yeeb nkab kom zoo thiab muaj kev txhawb nqa los ntawm qhov kub hloov.
Spherical expansion sib koom tes
Kev sib tw nthuav tawm cov pob qij txha muaj kev them nyiaj tau zoo heev thiab tuaj yeem them rau qee yam thiab tom qab. Nws yog siv nyob rau hauv cov xwm txheej nyuaj uas yuav tsum muaj kev them nqi rau lub tsev loj lossis cov kav dej loj ntawm cov tuam tsev loj. Nws cov qauv sib xws tuaj yeem tig hloov tau ntau yam, hloov rau ntau qhov chaw deformine, thiab paub meej qhov kev sib txuas thiab kev ua haujlwm zoo ntawm cov raj xa dej.
