Hauv kev ua tshuaj lom neeg, kev tiv thaiv ib puag ncigkev kho dej khib nyiab, kev tsim tshuaj, thiab kev lag luam ua ntawv, qhov kev ntsuas qhov ntws tseeb ntawm cov kua qaub thiab cov kua alkali corrosive tau ntev los ua qhov kev sib tw tseem ceeb. Cov khoom siv ntsuas ntws ib txwm muaj, xws li turbine thiab vortex flowmeters, feem ntau yuav xeb, thaiv, thiab cov ntaub ntawv hloov pauv thaum siv rau cov xov xwm corrosive heev, ua rau muaj kev saib xyuas ntau zaus, cov nqi hloov pauv siab, thiab kev ua haujlwm hauv kev lag luam tsis ruaj khov. Raws li lub cuab yeej ntsuas qhov tseeb thiab ntseeg tau siab, lub electromagnetic flowmeter tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau kev kuaj pom qhov ntws ntawm cov kua qaub thiab alkali muaj zog, vam khom nws txoj cai ua haujlwm tshwj xeeb thiab kev tsim qauv tiv thaiv xeb.
Electromagnetic cov ntsuas dej ntwsua haujlwm raws li Faraday txoj cai ntawm electromagnetic induction. Thaum cov kua conductive ntws los ntawm lub magnetic teb sib npaug hauv lub raj ntsuas, cov kua txiav cov kab magnetic induction thiab tsim cov teeb liab voltage induced. Qhov amplitude ntawm qhov voltage no yog ncaj qha proportional rau qhov nruab nrab ntws ntawm cov kua. Tom qab tau sau thiab ua tiav los ntawm lub electrode siab thiab transmitter system, qhov real-time volumetric ntws ntawm cov kua raug suav kom raug. Ib qho txiaj ntsig tseem ceeb ntawm txoj cai ua haujlwm no yog tias tsis muaj cov khoom txav mus los lossis cov khoom throttling hauv lub raj ntsuas, ua rau xoom qhov poob siab thiab tsis muaj kev cuam tshuam rau cov kua ntws. Qhov kev tsim kho no fundamentally zam kev hnav tshuab thiab cov khoom me me thaiv, zoo meej hloov kho rau lub sijhawm ntev txuas ntxiv ntsuas qhov xav tau ntawm cov tshuaj lom neeg corrosive.
Qhov kev hloov pauv zoo heev rau cov kua qaub thiab alkali muaj zog yog los ntawm kev sib phim cov khoom siv tiv thaiv xeb, uas yog qhov sib tw tseem ceeb ntawm cov ntsuas hluav taws xob hauv kev lag luam. Rau cov xov xwm acidic heev xws li hydrochloric acid, sulfuric acid, thiab nitric acid, tantalum electrodes thiab PTFE (polytetrafluoroethylene) lining tau txais yuav. Tantalum hlau ua rau muaj kev tiv thaiv corrosion zoo heev rau feem ntau cov kua qaub thiab oxidizing media, thaum PTFE lining tiv taus kev yaig thiab tshuaj lom neeg xeb yam tsis muaj kev cuam tshuam nrog cov kua qaub. Rau cov xov xwm alkali muaj zog xws li sodium hydroxide thiab potassium hydroxide kua, Hastelloy C alloy electrodes thiab roj hmab lossis PFA lining tau teeb tsa. Cov khoom siv sib xyaw ua ke no tuaj yeem tiv taus kev yaig tshuaj lom neeg mus sij hawm ntev, tiv thaiv electrode oxidation thiab lining laus, thiab xyuas kom meej tias kev ntsuas ruaj khov hauv cov chaw muaj kuab paug hnyav.
Piv nrog rau lwm cov cuab yeej ntsuas kev ntws,cov ntsuas hluav taws xobqhia txog qhov zoo uas tsis muaj qhov hloov pauv tau hauv kev ntsuas cov khoom siv corrosive. Ua ntej, lawv tsis raug cuam tshuam los ntawm cov kua viscosity, kub, qhov ceev, thiab cov khoom khov, ua rau kev ntsuas ruaj khov ntawm cov kua corrosive nrog ntau qhov sib txawv thiab cov kua sib xyaw ua ke ob-theem. Qhov thib ob, qhov tseeb ntawm kev ntsuas tuaj yeem ncav cuag ± 0.5% lossis txawm tias ± 0.2%, ua tau raws li cov qauv ntsuas nruj ntawm kev sib xyaw tshuaj lom neeg, kev saib xyuas cov dej khib nyiab hauv kev lag luam, thiab kev ntsuas kev thauj mus los hauv cov kav dej. Tsis tas li ntawd, cov qauv kaw sib xyaw ua ke thiab qib tiv thaiv IP68 tso cai rau cov cuab yeej hloov kho rau cov chaw ua haujlwm noo thiab corrosive, nrog lub neej ua haujlwm ntau dua 10 xyoo thiab cov nqi kho tom qab qis heev.
Tam sim no, tiv thaiv xebcov ntsuas hluav taws xobtau siv dav hauv cov xwm txheej kev lag luam thoob ntiaj teb. Hauv cov nroj tsuag tshuaj zoo, lawv ntsuas qhov kev thauj mus los thiab kev sib sau ua ke ntawm cov kua qaub thiab alkali raw kom ntseeg tau tias cov mis ntau lawm raug. Hauv kev lag luam tiv thaiv ib puag ncig, lawv saib xyuas cov dej khib nyiab acid-base hauv cov txheej txheem kho dej phwj tuaj yeem pab cov tuam txhab ua tau raws li cov qauv tso tawm. Hauv kev lag luam ntawv thiab textile, lawv txhawb nqa kev ntes cov dej ntws ntawm cov tshuaj dawb corrosive thiab cov kua ntxuav alkaline. Ntxiv mus, lub transmitter ntse tuaj yeem tso tawm 4-20mA analog teeb liab thiab cov teeb liab sib txuas lus digital, paub txog kev sib txuas seamless nrog kev lag luam PLC thiab DCS systems los txhawb kev tsim khoom tsis siv neeg thiab kev saib xyuas cov ntaub ntawv deb.
Xaus lus, nrog nws txoj kev tshawb fawb induction, kev teeb tsa tiv thaiv xeb, kev ntsuas qhov tseeb thiab kev ua haujlwm ruaj khov, tuslub tshuab ntsuas hluav taws xobtau daws tau tag nrho cov teeb meem ntsuas ntawm cov kua qaub thiab cov kua alkali corrosive. Nws tsis yog tsuas yog txhim kho qhov tseeb thiab kev ruaj khov ntawm kev ntsuas kua dej hauv kev lag luam xwb tab sis kuj txo cov nqi khiav lag luam thiab kev txij nkawm ntawm cov khoom siv, ua ib qho cuab yeej ntsuas tseem ceeb hauv kev lag luam tshuaj niaj hnub thiab kev tiv thaiv ib puag ncig.
