Cov dej khib nyiab flowmeteryog ib qho ntawm cov cuab yeej siv tau yooj yim dua, thiab nws cov kev xaiv kuj yog qhov nyuaj vim yog qhov muaj zog corrosiveness thiab tsis zoo ntawm cov khoom nws ntsuas, thiab vim nws muaj ntau yam, xws li electromagnetic flowmeters thiab throttle flowmeters Lwm cov dej khib nyiab flowmeters, thiab. integrated wastewater flowmeters thiab cais dej khib nyiab flowmeters, ces peb yuav tsum xyuam xim rau cov nram qab no yam thaum xaiv?
1. Muaj kev nkag siab zoo txog cov dej khib nyiab
Ua ntej yuav khoom pov tseg flowmeter, peb yuav tsum paub tias lub Hoobkas dej khib nyiab yog hom twg. Feem ntau, muaj cov dej khib nyiab hauv kev lag luam (xws li: fais fab nroj tsuag, steel nroj tsuag, tshuaj nroj tsuag, ntawv mills) thiab cov dej khib nyiab hauv tsev, thiab lwm yam. Cov dej khib nyiab sib txawv yog tsim rau cov dej khib nyiab sib txawv. Flow meters, xws li ntawv zeb khib nyiab dej ntws ntsuas. Nyob rau tib lub sijhawm, nws yuav tsum muaj tag nrho, cov ncauj lus kom ntxaws thiab kev nkag siab zoo ntawm cov khoom hauv cov dej phwj tuaj, thiaj li xaiv cov khoom siv hauv ob sab phlu thiab cov khoom siv electrode ntawm cov dej khib nyiab flowmeter. Piv txwv li, qhov loj ntawm corrosiveness ntawm cov dej khib nyiab, tus nqi ntawm cov khoom thiab cov khib nyiab nws muaj. Yog tias peb tsis paub ntau npaum li cas ntawm cov dej khib nyiab, peb tuaj yeem nkag siab txog qhov corrosiveness ntawm cov dej khib nyiab los ntawm kev txheeb xyuas cov khoom ntawm cov kav dej khib nyiab. Tom qab ntawd xaiv lub anti-corrosion hom khib nyiab flowmeter raws li qib ntawm corrosiveness.
2. Nkag siab tag nrho cov txheej txheem installation
Qhov chaw ib puag ncig nyob rau hauv uas lubdej khib nyiab flowmeteryog yuav tsum tau ntsia kuj ncaj qha cuam tshuam rau kev xaiv ntawm cov dej khib nyiab flowmeter. Nws tseem yog ib qho tsim nyog kom nkag siab tag nrho cov yeeb nkab ncaj nraim nyob rau hauv pem hauv ntej thiab qhov chaw cuam tshuam ntawm qhov chaw. Vim tias cov ntsuas dej khib nyiab sib txawv muaj qhov sib txawv ntawm ib puag ncig. Piv txwv li, lub installation ntawm electromagnetic flowmeter yuav tsum tau ib tug tej yam yeeb nkab seem (5D) nyob rau hauv pem hauv ntej ntawm nws, yuav tsum tsis txhob muaj zog cuam tshuam teeb liab ntawm qhov chaw, thiab lub site kub thiab av noo kuj yuav tsum tau raws li tej yam kev cai.
3. Nkag siab txog kev ua haujlwm ntawm flowmeter
Thaum xaiv ib lub flowmeter, nws yuav tsum nkag siab txog qhov ua tau zoo ntawm ntau yam flowmeters, thiab kom paub txog qhov tseeb, rov ua dua, linearity, turndown ratio, tso zis cov yam ntxwv thiab lwm yam ntawm cov dej khib nyiab flowmeter. Nws tseem yog ib qho tsim nyog kom nkag siab txog txoj kab uas hla ntawm cov kav dej khib nyiab, vim tias cov kev xav tau ntawm cov ntsuas dej sib txawv txawv. Piv txwv li, txhua lub caliber ntawm lub electromagnetic flowmeter muaj qee qhov kev xav tau ntawm qhov qis qis ntawm qhov ntws. Thaum qhov ntws tsawg dhau, qhov ntsuas qhov tseeb yuav tsis phim qhov tseeb. Thaum cov dej ntws tsawg dhau lawm, peb feem ntau ua tau raws li qhov yuav tsum tau ntsuas ntawm cov dej khib nyiab flowmeter los ntawm shrinking cov kav dej.
Tus nqi ntws ntawm cov dej khib nyiab sib txawv heev, thiab qhov sib xyaw ntawm cov dej khib nyiab tsis yooj yim los ntsuas. Nws muaj tsis tsuas yog ntau yam impurities, tab sis kuj muaj ntau yam. Cov dej khib nyiab kuj yog me ntsis conductive thiab corrosive. Qhov no muaj cov cai nruj heev rau ntau yam kev ua yeeb yam ntawmdej khib nyiab flowmeters, yog li peb yuav tsum tau kho cov kev ntsuas rau hauv cheeb tsam thiab tag nrho soj ntsuam ib puag ncig thiab dej khib nyiab thiaj li yuav xaiv cov dej khib nyiab uas haum tshaj plaws.
