Thaum twgcov cua kub exchangersrub tawm los ntawm cov ntawv raj hauv lub tshuab hluav taws xob tsis siv neeg lub tshuab hluav taws xob tag nrho, qhov no tsis yog tsuas yog txo cov khoom nruab nrab ntawm lub plhaub thiab cov cua kub pauv, tab sis kuj txo qis cov ntawv raj kev ntxhov siab los ntawm qhov sib txawv ntawm thermal expansion. Yog li ntawd, lub thickness ntawm lub raj ntawv yuav tsum raug txo kom tsim nyog.
Thaum xam cov ntawv raj ntawm lub raj ruaj khov-cov ntawv kub hloov pauv, yog tias ib qho ntawm cov hauv qab no ua tsis tau raws li qhov yuav tsum tau muaj zog (lossis kev ruaj ntseg)-xws li lub plhaub axial stress (σc) xam nyob rau hauv ntau yam kev ua hauj lwm nrog kub sib txawv, axial kev nyuaj siab ntawm lub tshav kub exchanger tubes, thiab lub tensile stress (q) ntawm lub tshav kub exchanges (q) ntawm daim ntawv yuav tsum tau muab faib ua 2 } sib koom.
Phaj heat exchangers yog cov cuab yeej tseem ceeb hauv ntau qhov kev lag luam. Txhawm rau kom yooj yim thaum siv, qee qhov kev ceev faj yuav tsum tau ua thaum lub sijhawm teeb tsa.
Txias- tsim cov pob qij txha txuas ua los ntawm cov hlau tsis muaj steel lossis qis- alloy steel xav tau kev kho cua sov kom tshem tawm cov kev ntxhov siab ua haujlwm txias.

Fully Automatic Heat Exchanger Unit
Kev suav thermal ntawm phaj kub exchangers ua raws cov cai tshwj xeeb. Feem ntau, muaj ob hom kev suav rau cov phaj kub hloov pauv: tsim kev suav thiab txheeb xyuas kev suav.
Kev khiav hauj lwm kub ntawm lub phaj kub exchanger yog txiav txim los ntawm qhov kub tsis kam ntawm sealing gaskets. Thaum siv cov roj hmab-raws li elastic gaskets, kev khiav hauj lwm kub yog qis dua 200 degree; Thaum compressed asbestos wool gaskets yog siv, qhov kev khiav hauj lwm kub ntawm 250℃mus rau 260 degree.
Thaum fouling nyob rau saum npoo ntawm daim hlau yog hnyav, corrosive cov ntsiab lus (xws li Cl, S) nyob rau hauv nruab nrab yuav feem ntau adheres rau lub fouling thiab accumulate nyob rau hauv lub qhov nyob rau hauv qab ntawm lub fouling txheej.
Tom qab cov phiaj xwm sib sau ua ke, ntau- cov qauv sib txawv tau tsim, suav nrog thaj chaw xws li cov ntsiab lus sib txuas ntawm cov phaj thiab hauv qab ntawm cov grooves sealing. Cov qhov khoob no ua rau Cl⁻ tsub zuj zuj, thiab cov qib hauv zos feem ntau nyob deb tshaj qhov kev ntxhov siab corrosion ntawm stainless hlau nws tus kheej.
Stainless hlau tshav kub hloov daim hlau yog tsim los ntawm mechanical stamping, uas inevitably tawm ib tug npaum li cas ntawm nto residual kev nyuaj siab. Rau nyias stainless hlau daim hlau uas tsis muaj molybdenum, tshem tawm cov seem residual kev nyuaj siab yog heev nyuaj, txawm tsis ua tau.
Yog xav paub meej txog cov kev qhia tshwj xeeb ntawm cov khoom siv hluav taws xob: Zoo siab txais tos hu rau peb, thiab peb yuav teb koj cov lus nug tam sim thiab xa cov phiaj xwm tsim nyog!
