1. Cov khoom ua kua dej:
Hom kua dej (xws li dej, roj, cua, thiab lwm yam).
Lub cev muaj zog ntawm cov kua dej, piv txwv li, ntom, viscosity, tshwj xeeb kub muaj peev xwm, thermal conductivity, thiab lwm yam.
Cov khoom siv tshuaj lom neeg ntawm cov kua dej, xws li seb puas muaj corrosive, seb nws puas muaj cov khib nyiab tshem tawm.
2. Cov xwm txheej ua haujlwm:
Flow rate (ntau npaum li cas los yog huab hwm coj flow rate).
Inlet thiab qhov hluav taws xob kub.
Siab (siab siab los yog ntsuas siab).
3. Thaum tshav kub kub hloov khoom yuav tsum tau:
Thaum tshav kub kub hloov pauv tus nqi (ntau npaum li cas ntawm tshav kub hloov mus rau ib chav tsev ntawm lub sij hawm, feem ntau qhia nyob rau hauv kilojoules los yog lab BTUs ib teev).
Kub qhov sib txawv (kub qhov sib txawv ntawm cov kua kub thiab txias).
Thaum tshav kub kub hloov coefficient (feem ntau yog nyob ntawm cov kua thiab cov khoom siv hluav taws xob sib hloov).
5. Cov qauv tsim nyog:
Dimensional txwv ntawm lub tshav kub exchanger, nrog rau qhov ntev, dav, thiab thickness.
Phaj sib nrug, phaj loj thiab phaj hom (xws li corrugated, tiaj tus phaj, thiab lwm yam).
Qhov loj thiab lub zog xav tau ntawm lub tshav kub exchanger plhaub.
6. Cov khoom siv xaiv:
Thaum tshav kub kub exchanger phaj thiab thav duab cov ntaub ntawv (xav txog corrosion kuj, kub kuj, lub zog, thiab lwm yam).
Sealing cov ntaub ntawv (gaskets, sealing daim kab xev, thiab lwm yam).
7.Kev tsim khoom thiab kev saib xyuas:
Manufacturing txheej txheem xav txog, xws li vuam, brazing, thiab lwm yam.
Kev saib xyuas yooj yim, xws li kev xav tau ntawm cov phaj tshem tawm, thiab lwm yam.
8. Kev xav txog nyiaj txiag:
Cov nqi peev (nrog rau cov khoom siv, kev tsim khoom, cov nqi tsim khoom).
Cov nqi khiav lag luam (kev siv hluav taws xob, nqi kho mob).
lub sij hawm them rov qab.
Tom qab txiav txim siab cov qauv tsim saum toj no, cov ncauj lus kom ntxaws txog kev hloov pauv hluav taws xob thiab cov kua dej dynamic tsom xam yuav tsum tau ua los xaiv cov phaj kub hloov pauv uas tsim nyog thiab qhov loj me thiab xyuas kom meej tias nws ua tau raws li qhov xav tau ntawm kev sib pauv cua sov hauv cov txheej txheem. Nyob rau tib lub sijhawm, lub zog ntawm cov qauv, kev sib khi ua haujlwm, kev tiv thaiv corrosion thiab lwm yam kev ntsuas ntawm lub tshav kub exchanger yuav tsum tau txiav txim siab raws li qhov tseeb daim ntawv thov ib puag ncig ntawm lub tshav kub exchanger los xyuas kom meej qhov kev cia siab thiab kev lag luam ntawm lub tshav kub exchanger.
