Muaj ntau qhov kev lag luam (feem ntau ntawm lawv) uas ntiav cov txheej txheem uas ua rau kev hloov ntawm cov cua sov ntawm ob lub kua. Tam sim no, yuav ua li cas raws nraim cov txheej txheem ntawm kev hloov hluav taws xob? Peb yuav qhib cov lus teb tam sim no. Nyeem ntxiv mus tshawb nrhiav!
Thaum tshav kub kub exchangers ua haujlwm li cas?
Ob lub kua dej ntawm qhov kub sib txawv yog muab tso rau hauv lub tshuab hluav taws xob thiab cov cua sov hloov ntawm qhov kub mus rau cov kua dej txias kom txog thaum ob lub kua dej mus txog qhov kub thiab txias. Ob leeg cov kua dej no yog nyob rau hauv kev sib cuag nrog ib lub raj phab ntsa uas ua ib tug conductive barrier. Muaj ntau hom thiab cov qauv ntawm cov khoom siv hluav taws xob sib txawv ua haujlwm rau cov txheej txheem no. Cov kev lag luam xaiv lawv cov khoom sib pauv raws li lub hom phiaj thiab cov xwm txheej ntawm qhov chaw.
Dab tsi yog corrugated tube heat exchanger? Nws ua haujlwm li cas?
Ib tug corrugated raj kub exchangertseem yog hom khoom siv hluav taws xob nrov heev uas siv los ntawm kev lag luam niaj hnub no - thiab tsis yog vim li cas. Cov cua kub exchangers no ua los ntawm kev ua kom muaj kev kub ntxhov. Qhov no, nyob rau hauv lem, renders siab dua kub hloov coefficient txawm ntawm tsawg Reynolds tus xov tooj. Lub corrugation ntawm lub plhaub raj, tseem hu ua programmed deformation yog lub luag hauj lwm rau qhov siab dua turbulence nyob rau hauv cov exchangers. Cov corrugated raj plhaub muab kauv kua dej ntws tawm tsam cov hlab nrog cov plhaub du.
Cov corrugated tube kub exchangers tuaj nrog sib txawv geometries. Hard corrugation paves txoj kev rau kev txhim kho ntau ntawm cov tshav kub hloov coefficient, uas dua, ua rau lub inevitable nce nyob rau hauv siab poob.
Cov yam ntxwv ntawm corrugated raj kub exchanger
- Nws muaj qhov du indented sab hauv uas tso cai rau kev tu yooj yim.
- Turbulence yog tsim los ntawm cov kua dej tsawg los txhim kho cov cua sov hloov mus rau qhov sib txawv ntawm cov cua sov ntau dua.
- Snarling ntawm lub raj ntiav yog qhov tsawg.
- Nws muaj nyob rau hauv ntau hom duab thiab diameters.
Ntau yam corrugation geometry
Mos corrugation: Kev hloov pauv ntawm lub raj corrugation HARD thiab lub raj du tsim txhim khu kev xa hluav taws xob mus rau qhov txo qis, txawm li cas los xij nrog kev poob qis.
Hard corrugation: Nws tso cai rau ua kom tiav qhov kev loj hlob ntawm cov cua sov hloov pauv uas muab nqi zog rau qhov nce siab hauv siab poob.
Cov txiaj ntsig ntawm corrugated tube heat exchangers
Mos corrugation, ntawm qhov tod tes, tso cai rau kev txhim kho cov cua sov tsawg dua tab sis lub siab poob qis dua. Puas yog koj tab tom tshawb fawb txog hom kev sib hloov cua sov tam sim no? Yog tias muaj, ces koj tuaj yeem so kom paub tseeb tias koj yuav tuaj hla corrugated tube heat exchangers raws li ib yam dab tsi uas tau siv dav hauv cov txheej txheem hloov hluav taws xob. Thiab vim li cas thiaj yog qhov ntawd? Needless hais, lub tshav kub exchangers yog siv dav - heev yooj yim vim hais tias ntawm qhov tseeb hais tias lawv muab ib tug xov tooj ntawm cov txiaj ntsig.
Ntawm no yog saib cov hlua ntawm qhov zoo uas muab los ntawm lawv:
- Lawv yog txuam nrog zoo dua tshav kub hloov coefficient thiab yog li ntau compact
- Lawv yooj yim heev rau nruab
- Lawv muab siab - ntxias kom muaj kev kub ntxhov yog li txo qis fouling - yog li ua haujlwm txuas ntxiv mus ntev heev tom ntej
- Muaj peev xwm nkag tau rau hauv cov duab modular thiaj li ua tiav lub luag haujlwm, raws li xav tau
- Lawv tuaj yeem ua tau nyob rau hauv qhov kub thiab txias
- Lawv tuaj yeem ua haujlwm rau kev hloov cov txheej txheem ua kua nrog cov khoom me me
- Tsawg-siab poob
- Zero gasket tsis ua haujlwm piv rau PHE
- Txawm tias tus nqi peev yog qis dua piv rau SHE / PHE
- Muaj ntau yam kev xaiv uas tuaj yeem nkag tau thaum nws tab tom raug teeb tsa - piv txwv li ntsug, kab rov tav lossis hauv ib qho kev nyiam.
- Yuav luag txij nkawm dawb
- Tsis muaj cua sov hauv zos
- Haum rau cov khoom uas rhiab rau cua sov
Koj daim ntawv thov kev sib pauv cua sov (xws li kev ua zaub mov, kev lag luam petrochemical, lub zog txias) thiab cov yam ntxwv nruab nrab (corrosiveness/viscosity/temperature) sib txawv, yog li cov phiaj xwm tshwj xeeb yuav raug hloov kho tshwj xeeb -thov qhia rau peb paub koj cov kev xav tau, thiab peb yuav muab koj cov phiaj xwm thiab cov lus hais.
