Xaiv cov kauj ruam ntawm tubular tshav kub exchanger
1. Nkag siab txog cov dej num hloov hluav taws xob thiab cov txheej txheem tus yam ntxwv thiab cov ntaub ntawv yooj yim:
(1). Kev khiav dej txias thiab dej kub, qhov nkag thiab qhov hluav taws xob kub, siab, thiab lwm yam.
(2). Txheej txheem cov yam ntxwv ntawm cov kua dej txias thiab kub, xws li corrosivity, tshem tawm cov khoom khib nyiab, thiab lwm yam.
(3). Cov ntaub ntawv lub cev ntawm cov kua dej txias thiab kub.
2. Kev suav cov ntsiab lus thiab cov kauj ruam:
(1). Xam lub tshav kub load.
(2). Xam qhov nruab nrab kub qhov sib txawv.
(3). Xaiv tag nrho cov tshav kub hloov coefficient raws li kev paub dhau los thiab kwv yees qhov chaw hloov hluav taws xob.
(4). Xaiv cov khoom siv hluav taws xob uas tsim nyog.
(5). Xam cov convective heat transfer coefficients ntawm lub raj sab thiab lub plhaub sab ntawm cov khoom siv hluav taws xob uas tau xaiv, thiab suav tag nrho cov cua sov hloov coefficient. Piv nrog rau kwv yees tag nrho cov tshav kub hloov coefficient. Yog tias qhov sib txawv loj, nws yuav tsum rov kwv yees.
(6). Xam qhov chaw hloov hluav taws xob raws li kev suav tag nrho cov tshav kub hloov coefficient thiab qhov nruab nrab kub qhov sib txawv. Piv nrog rau qhov chaw hloov hluav taws xob ntawm cov khoom siv hluav taws xob xaiv, yuav tsum muaj cov npoo ntawm 10 feem pua ~ 25 feem pua. Txwv tsis pub, rov xam los ntawm kauj ruam (3).
Yog li ntawd, hom kev xaiv xam yog ib qho txheej txheem ntawm kev rov sim xam, qee zaum ob lossis peb zaug.
