Teeb meem nyob rau hauv daim ntawv thov ntawm Fluoroplastic Teflon Thaum tshav kub kub Exchangers nyob rau hauv tshuaj lom neeg kev lag luam

1. Lub hom phiaj ntawm cov yeeb nkab rupture yog los txhim kho lub tshav kub hloov coefficient.
Cov neeg feem ntau siv cov kav dej nyias nyias nrog cov kab me me. Txhawm rau kom tau txais cov coefficient ntawm cov cua sov ntau dua thiab siv nws kom ntseeg tau raws li kev nyab xeeb. Qee cov tuam txhab lag luam hauv tsev ntawm fluoroplastic heat exchangers siv ib txoj kab uas hla ntawm 6 hli. fluorine yas kav nrog phab ntsa tuab ntawm 5ram yog siv los ua cov kav dej sib hloov cua sov. Vim qhov zoo ntawm cov raj xa dej raw khoom tsis ua raws li cov qauv. Tsis yog tib theem ntawm cov khoom siv raw. Cov txheej txheem tsim cov kav dej tsis huv.
Cov pab pawg fluoroplastic yeeb nkab tsis raug kev sim siab ua ntej vuam. Yog li, lub raj xa dej tuaj yeem tawg thaum lub sijhawm ua haujlwm; Hauv lwm qhov xwm txheej, cov khoom siv hluav taws xob sib txuas hluav taws xob yog ncaj qha los ntawm cov kua dej, ua rau muaj kev sib txhuam ntau dhau thiab tawg ntawm cov khoom siv hluav taws xob sib txuas thiab cov khoom xws li cov phab ntsa lossis cov phaj folding. Xwb, thaum lub tshav kub txauv raj ntim nrog lwm cov khoom siv nrog lub plhaub, cov khoom sib tiv tauj raug khawb vim tsis muaj lub vaj loj loj.
2. Kev hloov pauv ntawm qhov kub thiab txias ua haujlwm vim qhov xau ntawm qhov chaw sib khi.
Nws tuaj yeem ua rau thermal expansion thiab txias shrinkage ntawm cov khoom. Cov coefficient ntawm thermal expansion ntawm cov ntaub ntawv fluoroplastic yog ntau dua li cov ntaub ntawv hlau. Lub thermal expansion ntawm lub tshav kub exchanger raj pob yuav raug kho los ntawm qhov yooj ntawm lub tshav kub exchanger raj bundle nws tus kheej. Txawm li cas los xij, thaum tsim cov fluoroplastic plhaub thiab lub raj xa hluav taws xob, kev txiav txim siab yuav tsum tau muab rau thaum lub tshav kub pauv tube ntim ntawm qhov kub thiab txias thiab kev txhawb nqa los ntawm baffle daim hlau. Yuav lub thermal expansion thiab elongation ntawm lub tshav kub pauv tube pob ua rau lub raj ntim rau sag thiab tuaj rau hauv kev sib cuag nrog lub plhaub, uas ua rau kev puas tsuaj. Nyob rau ntawm no, siv lub plhaub hauv cov nplaum nplaum los yog lwm cov txheej hauv ob sab phlu yog ib txoj kev pabcuam zoo dua.
Qhov no tuaj yeem txo qhov kev sib txhuam kev puas tsuaj ntawm cov khoom siv hluav taws xob sib pauv thiab lub plhaub. Nws kuj tseem tuaj yeem tiv thaiv cov kua dej corrosive vim qhov tawg ntawm lub tshav kub txauv raj, uas ua rau corrosion ntawm lub casing sai. Lub thermal expansion ntawm lub raj xa ntawv yuav tsum tau saib xyuas ntau dua los ntawm cov neeg tsim qauv. Thaum lub raj phaj yog rhuab, axial thermal expansion yog txwv los ntawm kev sib txuas bolts ntawm lub raj phaj flange thiab lub taub hau sealing. Ua kom lub thermal expansion ntawm lub raj ntawv raws lub radial kev taw qhia.
Vim tsis zoo fluidity ntawm fluoroplastics. Qhov kub hloov pauv ua rau lub raj phaj tsis them nyiaj rau kev xau hauv axial kev taw qhia. Vim yog ib qho ntawm cov yam ntxwv ntawm fluoroplastics yog inelastic, lub xauv lub zog ntawm cov ntsia hlau txuas tuaj yeem ua rau tsis tuaj yeem deformation ntawm kev sib cuag ntawm lub raj phaj thiab lub gasket. Qee zaum nws tsuas yog yuav tsum tau disassembled ib zaug, thiab nws tuaj yeem xau thaum rov tsav tsheb. Txoj kev daws teeb meem yog siv cov tshuab ntxhua khaub ncaws zoo dua. Xws li fluororubber washers thiab tsim nyog locking quab yuam ntawm txuas screws.
3. Yooj yim los tuav thiab siv tau yooj yim.
Qhov teeb meem uas tib neeg saib tsis taus yog thaum siv perfluorinated fluoroplastic heat exchangers los yog fluoroplastic heat exchangers. Vim tias qhov hnyav ntawm tus kheej tsis txaus lossis qhov sib txawv tseem ceeb ntawm cov kua dej kub thiab txias, qee zaum lawv ntab. Lub teeb yuav cuam tshuam rau kev sib hloov cua sov. Hnyav yuav ua rau shrinkage los yog tawg ntawm lub tshav kub exchanger raj. Fluoroplastic heat exchangers, vim lawv cov khoom tseem ceeb yog fluoroplastics, yog qhov zoo heev piv rau cov khoom siv hluav taws xob tsis yog xim hlau xws li hlau.
