Cov phaj hloov cua sov siv dav hauv ntau yam lag luam rau kev hloov cua sov zoo ntawm ob lub kua. Lawv paub txog lawv qhov me me, ua haujlwm tau zoo thiab yooj yim saib xyuas. Thaum nws los txog rau cov phaj hloov cua sov, ob hom feem ntau yog gasketed thiab welded plate heat exchangers. Kev nkag siab txog qhov sib txawv ntawm ob hom no yog qhov tseem ceeb rau kev xaiv qhov kev xaiv tsim nyog tshaj plaws rau ib qho kev siv tshwj xeeb.
Gasketed Phaj Kub Exchanger:
Cov qauv tsim ntawm cov phaj hloov pauv cua sov uas muaj gasket muaj ntau daim phaj uas tau kaw ua ke nrog cov gaskets. Cov gaskets no tsim kom muaj lub foob nruj ntawm cov phaj, tiv thaiv ob lub kua dej sib pauv los ntawm kev sib xyaw. Gaskets feem ntau yog ua los ntawm cov ntaub ntawv xws li EPDM, roj hmab nitrile, lossis fluoroelastomer, nyob ntawm seb cov xwm txheej ua haujlwm thiab cov kua dej raug tuav.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov gasketed plate heat exchangers yog lawv qhov yooj ywm. Cov gaskets tuaj yeem hloov tau yooj yim, ua rau kev saib xyuas sai thiab tsis tas siv sijhawm ntau. Tsis tas li ntawd, cov gasketed plate heat exchangers yog qhov tsim nyog rau cov ntawv thov uas qhov xwm txheej ua haujlwm yuav txawv, vim tias cov gaskets tuaj yeem xaiv kom tiv taus qhov kub thiab txias sib txawv.
Txawm li cas los xij, cov phaj hloov pauv cua sov gasketed kuj muaj qee qhov kev txwv. Gaskets tuaj yeem lwj mus raws sijhawm, tshwj xeeb tshaj yog thaum raug rau qhov kub siab, cov kua corrosive, lossis cov voj voog kub ntau zaus. Qhov no tuaj yeem ua rau muaj peev xwm xau thiab xav tau kev saib xyuas ntau zaus.
Qhov sib txawv, cov phaj hloov cua sov uas vuam tau ua los ntawm cov hlau tsis muaj gaskets. Hloov chaw, cov phaj raug vuam ua ke los tsim kom muaj lub foob ruaj khov thiab ruaj khov. Qhov kev tsim no tshem tawm qhov kev pheej hmoo ntawm kev ua tsis tiav ntawm gasket thiab tej zaum yuav xau, ua rau cov phaj hloov cua sov uas vuam tau tsim nyog rau cov ntawv thov uas muaj qhov kub siab, cov kua dej corrosive, thiab cov xwm txheej siab.
Qhov tsis muaj gaskets kuj txhais tau tias cov welded plate heat exchangers muaj qhov me dua thiab muaj qhov pheej hmoo tsawg dua ntawm kev ua qias vim tias tsis muaj gasket grooves uas cov deposits tuaj yeem sib sau ua ke. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas qhov chaw tsawg thiab kev huv yog qhov tseem ceeb.
Txawm li cas los xij, qhov tsis muaj gaskets kuj txhais tau tias cov phaj hloov pauv cua sov welded tsis yooj yim dua thaum nws los txog rau kev saib xyuas thiab kev kho dua tshiab. Thaum cov phaj tau welded ua ke, lawv tsis tuaj yeem yooj yim rhuav tshem rau kev ntxuav lossis kho. Tsis tas li ntawd, tus nqi pib ntawm cov phaj hloov pauv cua sov welded feem ntau siab dua li cov phaj hloov pauv cua sov gasketed vim yog qhov kev vuam raug.
Qhov sib txawv tseem ceeb:
1. Kev Txij Nkawm: Cov khoom siv hloov cua sov uas muaj gasketed yooj yim dua rau kev txij nkawm thiab yoog tau rau kev hloov kho, thaum cov khoom siv hloov cua sov uas vuam tau muaj kev tsim kho ruaj khov dua thiab tsis tas yuav txij nkawm.
2. Cov xwm txheej ua haujlwm: Cov khoom sib pauv cua sov gasketed yog tsim rau ntau yam kev ua haujlwm sib txawv, thaumcov phaj welded cua sov exchangersyog qhov tsim nyog dua rau qhov kub thiab txias, siab siab thiab cov kua dej corrosive.
3. Tus nqi: Tus nqi pib ntawm lub gasketed plate heat exchanger feem ntau qis dua, thaum lub peev nyiaj ua ntej ntawm lub welded plate heat exchanger yuav siab dua.
Hauv kev xaus lus, qhov kev xaiv ntawm cov khoom siv hloov cua sov gasketed thiab cov khoom siv hloov cua sov welded nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov. Cov khoom siv hloov cua sov gasketed muab kev ywj pheej thiab yooj yim rau kev saib xyuas, thaum cov khoom siv hloov cua sov welded muab kev daws teeb meem muaj zog dua thiab siv tau ntev dua rau cov xwm txheej ua haujlwm hnyav. Kev nkag siab txog qhov sib txawv ntawm ob hom no yog qhov tseem ceeb rau kev xaiv qhov kev xaiv tsim nyog tshaj plaws rau kev hloov cua sov zoo thiab txhim khu kev qha hauv ntau yam txheej txheem kev lag luam.
