Ib qho electromagnetic flowmeter yog ib qho cuab yeej rau kev ntsuas qhov ntws ntawm cov kua hluav taws xob raws li Faraday txoj cai ntawm electromagnetic induction. Nws yog tsim los ntawm cov sensors, electrodes, teeb liab processors, thiab lwm yam. Electrodes yog cov khoom tseem ceeb ntawm electromagnetic flowmeters. Xaiv cov khoom siv electrode uas tsim nyog tshaj plaws raws li cov khoom ntawm cov kua ntsuas tsis tuaj yeem ua kom qhov ntsuas qhov tseeb ntawm electromagnetic flowmeter tab sis kuj ua kom nws lub neej kev pab.
1. Electrode khoom faib:
Cov khoom siv ntawm electrode muaj ib qho tseem ceeb ntawm lub neej, corrosion kuj, precision, thiab lwm yam khoom ntawm electrode. Yav dhau los, cov khoom siv electrode feem ntau yog stainless hlau, hlau alloy, titanium, tantalum, platinum, thiab lwm yam.
Stainless hlau electrode:Nws qhov zoo muaj xws li kev pab cuam lub neej ntev thiab muaj zog corrosion kuj, ua rau nws yog ib qho khoom siv electrode thiab siv tau.
Alloy hlau electrode:Nws muaj qhov zoo ntawm hardness siab, corrosion kuj, hnav tsis kam, thiab lwm yam, tab sis nws tus nqi kuj yog siab heev.
Titanium electrode:Nws muaj lub zog zoo heev thiab kev tiv thaiv corrosion, tab sis nws tus nqi yog kim.
Tantalum electrode:Nws muaj kev tiv thaiv corrosion siab thiab ruaj khov thiab tuaj yeem siv rau hauv qhov chaw hnyav heev, tab sis nws tus nqi kim heev.
Platinum electrode:Nws muaj cov conductivity zoo heev thiab tuaj yeem ntsuas qhov qis qis thiab cov cim tsis muaj zog ntawm cov kua, tab sis nws tus nqi siab dua li lwm cov ntaub ntawv.
Yog li ntawd, kev xaiv cov khoom siv electrode yuav tsum tau txiav txim siab raws li qhov siv tau tiag tiag thiab cov khoom ntawm cov kua yuav ntsuas.
2. Electrode daim ntawv:
Daim ntawv ntawm cov electrode tseem yuav cuam tshuam rau kev ua haujlwm ntawm electrode. Tam sim no, cov ntaub ntawv ntawmSib nqus flowmeterelectrodes feem ntau muaj xws li cov phaj tiaj tiaj, hom kauv, hauv ob sab phlu, thiab lwm yam.
Flat phaj hom:
Electrode nto ntawm lub phaj phaj hom electrode yog tiaj tus, uas yog tsim rau kev ntsuas lub sijhawm nrog ceev ceev thiab cov kua dej huv, tab sis tej zaum yuav muaj teeb meem nrog lub cim yooj yim ntawm cov pa paug thiab cov av noo.
Insertion hom:
Qhov ntxig electrode yog ntxig cov electrode rau hauv cov yeeb nkab, uas yog tsim rau kev ntsuas cov kua tsis ruaj khov. Kev ntsuas qhov tseeb ntawm qhov ntxig electrode yog siab dua li ntawm cov phaj tiaj tiaj, tab sis nws yog ib qho tsim nyog los xyuas kom meej tias cov electrode ua raws li cov yeeb nkab, uas yog qhov nyuaj rau kev teeb tsa.
Kauv hom:
Lub electrode nto ntawm cov kauv electrode yog kauv, uas yog tsim rau kev ntsuas lub sij hawm uas tsis tshua muaj txaus tus nqi thiab viscous kua, tab sis cov kev pab cuam lub neej yog luv dua li ntawm lub tiaj phaj electrode.
Lined hom:
Sab hauv txheej electrode yog coated nrog insulating cov ntaub ntawv nyob rau hauv lub electrode, uas yog haum rau ntsuas corrosive thiab scaling kua, tab sis cov ntaub ntawv hauv ob sab phlu yuav tsum tau xaiv raws li corrosiveness ntawm cov kua.
