Xaiv txoj cai ntxig-hom magnetic flatermeter yog qhov tseem ceeb los ua kom ntseeg tau tias yog, txhim khu kev qha ua kua, thiab ntev-ntev ntev kev ntsuas hauv cov ntawv thov ntau yam.
Cov neeg txaus ntshai no tshwj xeeb tshaj yog pab rau txoj kab uas loj-ntawm cov kav dej loj, muab tus nqi rau kev siv tau nqi rau tag nrho cov neeg muaj kev sib nqus txaus. Txawm li cas los xij, tsis yog tag nrho cov ntxig-hom sib nqus Flatmeters raug tsim kom sib npaug. Xaiv txoj cai ib qho yuav tsum muaj cov ncauj lus kom ntxaws ntawm daim ntawv thov cov xwm txheej, cov kua khoom, ib puag ncig kev tshwj xeeb, thiab ib puag ncig kev ua haujlwm.
Nov yog phau ntawv qhia dav dav los pab koj xaiv qhov haumntxig-hom sib nqus flatermeter:
1. Nkag siab txog daim ntawv thov yuav tsum tau ua
Ua ntej xaiv cov neeg muaj kev cuam tshuam, nws yog qhov tseem ceeb kom txhais cov cai ntawm daim ntawv thov:
Dab tsi ntawm kua yog ntsuas?
Kev nkag-hom hlau nplaum flatermeters tsuas yog ua haujlwm nrog hluav taws xob ua kua, xws li dej, slurries, khib nyiab, lossis tshuaj lom neeg. Yog tias cov kua dej ua tau tsawg dhau (feem ntau hauv qab 5 μs \/ cm), lub meter yuav tsis ua haujlwm zoo.
Dab tsi yog cov yeeb nkab loj?
FlockMeters FlowMeters yog qhov zoo tagnrho rau cov kav dej nrog cov kab mob diameters tshaj 100 mm (4 ntiv). Xyuas kom tus qauv xaiv tuaj yeem haum raws li lub cheeb ntawm koj cov yeeb nkab.
2. Ntsuam xyuas cov kua dej
Nkag siab txog cov khoom ntawm cov kua ntsuas yog qhov tseem ceeb:
Conduction: Cov kua dej yuav tsum muaj hluav taws xob hluav taws xob zoo. Dej, kua qaub, mis nyuj, pulp slurry, thiab feem ntau cov dej khib nyiab loj tshaj.
Qhov kub thiab txias: Xyuas kom cov ntaub ntawv muaj flumeter thiab electronics tuaj yeem tiv taus qhov kev ua haujlwm kub.
Siab: lub sensor thiab cov tshuab sib sau yuav tsum tau ntsuas rau lub kaw lus siab.
Corrosive: rau cov tshuaj ua kom haum, xaiv meters nrog electrode thiab cov khoom siv hluav taws xob tiv thaiv kev ua tshuaj tua kab, xws li PTFE, hastelloy, lossis titanium.
3. Txheeb xyuas cov tshuab hluav taws xob
Txoj kev nkag cuam tshuam cuam tshuam rau kev saib xyuas yooj yim thiab ntsuas kev ntseeg tau:
Kub-kais muaj peev xwm: Yog tias cov txheej txheem kab tsis tuaj yeem kaw rau kev teeb tsa lossis kev saib xyuas, ib tus qauv sib tw kub uas tso cai rau kev raug tshem tawm thiab rov ua dua hauv siab.
Taag Vs. Adminustable Qhov tob: Cov kev kho kom haum yog qhov zoo tagnrho rau cov ntsiab lus sib txawv lossis cov ntsiab lus tob siv tau yooj yim rau nruab tab sis tsis yooj yim dua.
4. Txheeb xyuas qhov tseeb thiab kev rov ua dua
Kev siv cov ntxig ntxig feem ntau muab cov qauv qis dua li cov qauv ua qauv puv ntoob. Txawm li cas los xij, rau ntau cov txheej txheem muaj, ± 1% rau ± 2% yog tau txais.
Tshawb xyuas cov chaw tsim khoom ntawm cov ntawv teev cov ntawv tshwj xeeb rau qhov raug thiab rov ntsuas dua.
Xav txog cov qauv hluav taws xob muaj ntau lossis cov qauv nrog cov nyiaj ntsuab ntws los txhim kho qhov tseeb hauv qhov tsis zoo.
5. Kev Nruab Nruab Nrab Ib puag ncig
Koj lub chaw teeb tsa yuav cuam tshuam cov kev cai tshwj xeeb:
Puas yog qhov chaw yooj yim rau kev saib xyuas? Xaiv cov qauv sib xyaw lossis cov qauv chaw taws teeb rau thaj chaw nyuaj.
Puas yog ib puag ncig kev puas tsuaj, ntub, lossis plua plav? Xaiv ib lub 'meter' nrog tus IP kev ntaus nqi tsim nyog (piv txwv li, IP65, IP67) lossis tawg-pov thawj tsev.
Cov Hluav Taws Xob Hluav Taws Xob: Ua kom cov kev xaiv tsim nyog hauv av muaj rau cov kab ke uas cov ntaub ntawv yeeb nkab cov khoom tsis yog xim hlau.
6. Kev sib txuas lus thiab cov zis xaiv
Xaiv cov qauv uas sib xyaw tau yooj yim nrog koj cov kev tswj hwm lossis tshuaj xyuas cov txheej txheem:
Analog cim (4-20 ma) rau PLCS
Mem tes tsim tawm rau tag nrho lossis batching
Cov Txheej Txheem digital (modbus, HART, Profibus) rau Scada lossis DCS kev sib xyaw
Cov zaub hauv zos nrog tus nqi ntws, tag nrho tag nrho, thiab kuaj mob
