Cov Kev Txwv ntawm Electromagnetic Flow Meters: Thaum Twg Tsis Txhob Siv Lawv

Cov ntsuas hluav taws xob electromagneticsiv dav hauv kev ntsuas kev ntws hauv kev lag luam vim lawv qhov tseeb siab, tsis tas yuav saib xyuas, thiab tsis muaj qhov chaw txav mus los. Txawm li cas los xij, lawv tsis haum rau txhua daim ntawv thov. Hauv tsab xov xwm no, peb yuav tham txog cov xwm txheej uas cov ntsuas hluav taws xob tsis yog qhov kev xaiv zoo tshaj plaws, pab koj xaiv cov cuab yeej ntsuas kev ntws zoo tshaj plaws.

1. Cov kua ntsuas yuav tsum yog cov khoom siv hluav taws xob

Cov ntsuas hluav taws xob electromagnetic ua haujlwm raws li Faraday Txoj Cai ntawm Induction, uas xav kom cov kua ntsuas muaj qee qib ntawm kev ua hluav taws xob. Feem ntau, qhov ua tau zoo ntawm cov kua yuav tsum ntau dua5 μS/cm(microsiemens ib centimeter); txwv tsis pub, qhov hluav taws xob induced yuav tsis muaj zog dhau rau kev ntsuas qhov tseeb.

Cov Xwm Txheej Tsis Tsim Nyog:

• Dej ntshiab, dej deionized
• Cov khoom siv roj av (piv txwv li, roj av, diesel)
• Cov kuab tshuaj organic uas rwb thaiv tsev zoo heev (piv txwv li, ether, benzene)

2. Tsis Haum Rau Cov Roj Av, Cov Pa, lossis Cov Khoom Qhuav Tag Nrho

Vim tias cov ntsuas hluav taws xob xav kom cov yeeb nkab puv nrog kua rau kev ntsuas ruaj khov, lawv tsis tuaj yeem siv rau kev ntsuas roj, pa dej, lossis cov khoom qhuav tag nrho.

Cov Xwm Txheej Tsis Tsim Nyog:

• Kev ntsuas cua compressed, natural gas flow
• Kev ntsuas dej ntws
• Cov hmoov qhuav los yog cov khoom siv granular (piv txwv li, cement, nplej)

3. Cov kua xeb lossis cov kua kub siab yuav cuam tshuam rau lub neej ntawm lub sensor

Txawm hais tias cov ntsuas hluav taws xob electromagnetic flow meters tuaj yeem nruab nrog cov ntaub thaiv uas tiv taus xeb (xws li PTFE) thiab cov electrodes (piv txwv li, Hastelloy, Tantalum), qee qhov chaw ib puag ncig hnyav tseem tuaj yeem cuam tshuam rau kev ruaj khov thiab lub neej ntev ntawm cov cuab yeej. Cov kua qaub muaj zog, cov hauv paus muaj zog, lossis cov kua kub siab yuav ua rau lub sensor laus lossis puas tsuaj sai dua.

Cov Xwm Txheej Tsis Tsim Nyog:

• Cov kua qaub sulfuric acid uas muaj concentration siab, hydrofluoric acid, thiab lwm yam kua dej uas muaj zog heev
• Cov kua uas muaj qhov kub uas tshaj qhov kam rau cov khoom siv (piv txwv li, >180°C)

4. Cov Nqi Nqus Tsawg lossis Cov Kua Uas Muaj Cov Npuas Yuav Cuam Tshuam Rau Kev Ruaj Ntseg

Cov ntsuas hluav taws xob electromagnetic flow meters nyuaj rau ntsuas cov nqi ntws qis (feem ntau hauv qab no)0.1 m/s) kom raug vim tias qhov hluav taws xob uas tshwm sim tsis muaj zog thiab yooj yim rau kev cuam tshuam. Ntxiv mus, yog tias cov kua dej muaj ntau cov npuas cua, lub teeb liab tuaj yeem tsis ruaj khov, cuam tshuam rau qhov tseeb ntawm kev ntsuas.

Cov Xwm Txheej Tsis Tsim Nyog:

• Kev ntsuas cov kua dej ntws tsawg heev (piv txwv li, leachate, kev ntsuas tshuaj lom neeg ntws tsawg)
• Cov kua uas muaj roj ntau (piv txwv li, cov tshuaj sib xyaw tshiab, cov dej khib nyiab uas muaj cua nkag)

5. Ib puag ncig uas muaj kev cuam tshuam hluav taws xob muaj zog

Cov ntsuas hluav taws xob electromagnetic flow meters rhiab heev rau kev cuam tshuam electromagnetic sab nraud. Yog tias qhov chaw teeb tsa nyob ze rau cov cav loj, cov tsav hloov pauv zaus, lossis cov xov hluav taws xob siab, nws tuaj yeem cuam tshuam kev ruaj khov ntawm kev ntsuas.

Cov Xwm Txheej Tsis Tsim Nyog:

• Nyob ze ntawm cov chaw hloov hluav taws xob lossis cov kab hluav taws xob muaj zog siab
• Ib puag ncig muaj zog magnetic teb (piv txwv li, cov cav loj, cov khoom siv vuam)

Xaus Lus: Yuav Ua Li Cas Xaiv Lub Flow Meter Yog?

Yog tias koj daim ntawv thov ua tau raws li cov xwm txheej hauv qab no, lub tshuab ntsuas hluav taws xob electromagnetic flow meter tuaj yeem yog qhov kev xaiv zoo heev:
✅ Cov kua dej yog kua thiab muaj conductivity txaus
✅ Qhov kub thiab qhov xeb ntawm cov kua dej poob rau hauv qhov ntsuas qhov kam rau siab
✅ Cov yeeb nkab puv nrog kua, thiab qhov ntws tsis qis dhau
✅ Ib puag ncig teeb tsa tsis muaj kev cuam tshuam hluav taws xob loj heev
