Common Classification Ntawm Tube Bundle Thaum tshav kub kub Exchangers
Tube Bundle Thaum tshav kub kub Exchanger-Introduction to Tube Bundle Heat Exchanger
Nyob rau hauv lub raj bundle heat exchanger, ob hom kua pauv cua sov, ib tug ntws nyob rau hauv lub raj, thiab nws cov hlab ntsha yog hu ua lub raj sab; lwm yam ntws tawm sab nraum lub raj, thiab nws cov hlab ntsha yog hu ua lub plhaub sab. Lub phab ntsa ntawm lub raj ntim yog lub tshav kub hloov chaw. Txhawm rau txhim kho cov cua sov hloov coefficient ntawm cov kua dej sab nraud ntawm lub raj, qee tus naj npawb ntawm transverse baffles feem ntau yog ntsia rau hauv lub plhaub. Lub phaj baffle tsis tuaj yeem tiv thaiv qhov luv luv ntawm cov kua dej, ua kom lub nrawm nrawm ntawm cov kua dej, tab sis tseem yuam kom cov kua dej hla dhau los ntawm lub raj ntim ntau zaus raws li txoj hauv kev, kom cov qib ntawm turbulence zoo heev. nce. Feem ntau siv baffles yog ncig thiab disc-puab, thiab cov qub yog siv ntau dua. Txhua zaus cov kua dej hla lub raj ntim hauv lub raj yog hu ua tube pass, thiab txhua zaus cov kua dej hla lub plhaub hu ua plhaub dhau. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau hauv cov kav dej, cov txheej txheem tsim nyog yuav tsum tau muab tso rau hauv lub taub hau ntawm ob qhov kawg kom faib tag nrho cov kav dej mus rau ntau pawg sib npaug. Ua li no, cov kua dej tuaj yeem rov qab mus rau ntau zaus los ntawm tsuas yog ib feem ntawm cov hlab ntsha ntawm ib lub sijhawm, uas yog hu ua multi-pass. Ib yam li ntawd, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov Nyob rau hauv lub raj bundle heat exchanger, vim qhov sib txawv ntawm cov kua dej sab hauv thiab sab nraud ntawm lub raj, qhov kub ntawm lub plhaub thiab lub raj ntim kuj sib txawv.
Tube Bundle Heat Exchanger - Kev faib ua feem ntawm Tube Bundle Thaum tshav kub kub Exchangers
Fixed tube-daim ntawv kub exchanger:Lub taag-tube-daim ntawv tshav kub exchanger welds lub raj ntawv ntawm ob hnub ncaj qha mus rau lub plhaub. Nws yog tsuas yog tsim los ntawm lub plhaub, raj ntawv, raj pob, lub taub hau thiab lwm yam tseem ceeb. Lub plhaub yog muab nrog ib lub raj ntim, thiab ob qhov kawg ntawm lub raj ntim yog tsau rau ntawm daim ntawv raj los ntawm kev vuam, kev sib koom ua ke los yog kev nthuav dav vuam, thiab sab nraud ntawm cov ntawv raj thiab lub taub hau flange yog fastened nrog bolts. Lub taag tube-daim ntawv kub exchanger muaj qhov zoo ntawm cov qauv yooj yim, tsis tshua muaj nqi, yooj yim siv, thiab yooj yim tu thiab txij nkawm ntawm lub raj sab, tab sis nws yog ib qho nyuaj rau ntxuav lub plhaub sab, thiab muaj qhov kub thiab txias qhov sib txawv tom qab lub raj. pob khoom yog tsim. Thaum muaj qhov sib txawv ntawm qhov kub thiab txias ntawm qhov sib txawv ntawm lub tshav kub thiab lub plhaub, ib qho kev sib koom ua ke yuav tsum tau muab rau ntawm lub plhaub.
Floating taub hau kub exchanger:Ib qho kawg ntawm lub taub hau hluav taws xob hloov hluav taws xob yog tsau ntawm lub plhaub thiab lub thawv raj, thiab lwm qhov kawg ntawm lub phaj phaj tuaj yeem txav mus los hauv lub plhaub, uas yog, thermal expansion ntawm lub plhaub thiab lub raj ntim tuaj yeem ua tau dawb. Yog li ntawd, tsis muaj qhov sib txawv ntawm qhov kub thiab txias ntawm cov hlua khi thiab lub plhaub. Feem ntau, lub taub hau ntab yog detachable, thiab lub raj ntim tuaj yeem rub tawm thiab thauj khoom dawb. Cov qauv no ntawm lub taub hau hluav taws xob hloov hluav taws xob tuaj yeem siv rau hauv kev ua haujlwm uas muaj qhov sib txawv ntawm qhov kub thiab txias ntawm lub raj ntim thiab lub plhaub. Kev tu thiab tu ntawm lub raj ntim thiab lub plhaub yog qhov yooj yim, tab sis nws cov qauv yog qhov nyuaj, thiab cov kev cai rau kev sib khi yog qhov siab.
"U"-shaped tube kub exchanger:U-shaped tube bundle heat exchanger yog U-shaped heat exchange tube, thiab ob qhov kawg yog tsau rau tib lub raj ntawv. Txij li thaum lub plhaub thiab lub tshav kub pauv cov hlab yog sib cais, lub tshav kub pauv tube pob tuaj yeem nthuav dav thiab cog lus ywj pheej, thiab tsis muaj qhov sib txawv ntawm qhov kub thiab txias yuav raug tsim vim qhov kub ntawm qhov nruab nrab. U-tube kub exchanger tsuas muaj ib daim ntawv raj, tsis muaj lub taub hau ntab, thiab cov qauv yooj yim. Lub hnab ntim lub raj tuaj yeem rub tawm thiab thauj khoom dawb, uas yooj yim rau kev ntxuav. Nws muaj qhov zoo ntawm lub taub hau ntab dej kub exchanger. Txawm li cas los xij, txij li cov raj xa hluav taws xob tau ua rau hauv U-zoo li khoov nrog cov radii tsis sib xws, lub raj xa hluav taws xob sab nraud tuaj yeem hloov tau tom qab kev puas tsuaj. Lwm cov raj Qhov kev puas tsuaj tsuas yog thaiv tau. Nyob rau tib lub sijhawm, piv nrog cov khoom siv hluav taws xob ruaj khov-daim ntawv hluav taws xob, vim tias lub raj xa hluav taws xob tau txwv los ntawm lub vojvoog dabtsi yog khoov, muaj qhov sib txawv ntawm qhov nruab nrab ntawm lub raj ntim, thiab cov kua dej tau yooj yim luv luv, uas cuam tshuam. lub tshav kub hloov nyhuv.
