Dab tsi koj yuav tsum paub txog kev ntxuav cov cua kub sib txawv?
Plhaub thiab raj kub exchangersyog tsim los ua -tab sis tsuas yog lawv tau ntxuav thiab tswj kom zoo. Txawm hais tias koj tab tom npaj lub kaw lus tshiab lossis ntsuas koj qhov tam sim no, kev nkag siab txog kev teeb tsa lub raj cuam tshuam li cas tuaj yeem pab koj kom tsis txhob muaj sijhawm poob qis, fouling, thiab kev kho nqi kim.
Cia peb rhuav tshem cov kev teeb tsa lub raj feem ntau thiab koj yuav tsum paub dab tsi kom lawv huv si thiab ua haujlwm tau zoo.
Tsau Tube Sheet Thaum tshav kub kub Exchangers
Kev tsim qauv ncaj nraim, tu ncaj nraim-feem ntau.
Lub raj xa hluav taws xob ruaj khov yog nrov rau lawv txoj kev yooj yim thiab tus nqi -kev ua tau zoo. Cov hlab yog ncaj thiab welded rau lub plhaub, ua rau kev tsim kho thiab txhim khu kev qha.
Lub tswv yim ntxuav:
Tube sab ntxuav yog ib qho yooj yim.Tsuas yog tshem lub kaus mom thiab koj nyob hauv. Txhuam, hoses, lossis cov tshuaj tua kab mob tuaj yeem nkag mus ncaj nraim nrog kev siv zog tsawg.
Plhaub sab ntxuav? Trickier.Txij li thaum daim ntawv raj yog welded nyob rau hauv, mechanical nkag mus rau lub plhaub sab yog yuav luag tsis yooj yim sua. Koj yuav tsum tau siv cov tshuaj ntxuav cov tshuaj-thiab xyuas kom meej tias lawv tau ntws tawm tag nrho tom qab ntawd kom tsis txhob muaj xeb lossis paug.
Bonnet style tseem ceeb.L-hom thiab N- hom bonnets tso cai yooj yim nkag tsis tau tshem cov kav dej. M- hom kaus mom? Tsis ntau npaum li ntawd -koj yuav tau tshem tag nrho lub taub hau.
Qhov zoo tshaj plaws rau:Siv cov kua dej huv ntawm lub plhaub sab lossis cov tshuab uas fouling tsawg heev.
U-Tube Heat Exchangers
Yooj yim rau kev khiav lag luam, tsawg dua hauv kev tu.
Tsuas yog ib daim ntawv raj thiab rov qab khoov, U-tube exchangers yog qhov zoo rau cov ntawv thov uas muaj thermal expansion. Tab sis qhov khoov ntawm qhov kawg? Nws nyuaj rau kev ntxuav.
Lub tswv yim ntxuav:
Tube sab yog tawv.Kev tu tshuab yog txwv tshwj tsis yog tias koj siv cov cuab yeej hloov tau yooj yim -shaft cov cuab yeej lossis cov txhuam txhuam. Kev ntxuav tshuaj yog ua tau, tab sis hardened scaling ntawm khoov yuav tawv ncauj.
Plhaub sab yog cua.Ib daim ntawv raj ua rau disassembly yooj yim dua, tso cai ncaj nraim mus ntxuav lub plhaub thiab sab nraud ntawm cov hlab.
Qhov zoo tshaj plaws rau:Tsis yog - cov kev pabcuam fouling ntawm lub raj sab thiab thaum thermal expansion yog ib qho kev txhawj xeeb loj.
Floating Head Heat Exchangers
Qhov zoo tshaj plaws ntawm ob lub ntiaj teb no - ntxuav thiab yoog raws.
Floating head exchangers muab kev ntxuav yooj yim ntawm cov raj ncaj nrog kev yooj yim los lis kev nthuav dav zoo li U- raj. Ib daim ntawv raj yog tsau; lwm qhov "floats" kom haum rau kev txav mus los.
Lub tswv yim ntxuav:
Tube sab ntxuav yog ib qho yooj yim.Cov raj ncaj txhais tau tias cov txhuam hniav thiab cov hoses ua haujlwm zoo.
Plhaub sab ntxuav kuj siv tau.Ntau lub taub hau ntab tsim tso cai rau koj tshem tawm tag nrho lub raj ntim rau qhov tob tob.
Saib lub taub hau rear tsim.
P- hom:Ib qho yooj yim raj sab nkag, tab sis koj tsis tuaj yeem rub lub nras.
S- hom:Bundle yog tshem tau tab sis nyuaj rau disassemble.
T- hom:Kev tshem tawm thiab ntxuav tau yooj yim dua - feem ntau nyiam, txawm tias kim dua me ntsis.
W-type:Kuj yooj yim tshem tawm thiab feem ntau siv nyiaj ntau dua - tus phooj ywg.
Qhov zoo tshaj plaws rau:Kev siv nrog hnyav fouling lossis thermal cycling, xws li roj av ua los yog reboilers.
Kev txiav txim siab huv huv=Kev txiav txim siab tsim qauv ntse dua
Thaum xaiv lossis tswj cov khoom siv hluav taws xob, tsis txhob kho kev tu raws li kev xav tom qab. Xaiv qhov kev teeb tsa lub raj zoo rau koj cov txheej txheem-thiab paub yuav ua li cas ntxuav nws- tuaj yeem txhim kho kev ua haujlwm, txo qis qis, thiab txuas ntxiv lub neej ntawm koj cov cuab yeej.
Tsis paub tseeb tias qhov teeb tsa twg yog qhov zoo tshaj rau koj txoj haujlwm?Tiv tauj pebrau kev taw qhia kom haum rau koj cov txheej txheem.
GNEE tau tsim muaj nyob rau xyoo 2008. Nws yog cov chaw tsim khoom thiab cov chaw muag khoom nrog kev nplua nuj hauv kev muab cov khoom lag luam customized hauv kev lag luam tshav kub hloov pauv.
Peb ib txwm ua "ib qho- nres kev pabcuam los ua kom xaiv tau yooj yim dua" raws li peb lub luag haujlwm, thiab tau cog lus los muab cov neeg siv khoom nrog- cov khoom zoo thiab kev txhawb nqa kev pabcuam.
