Nkag Siab Txog Cov Khoom Siv Sab Hauv Rau Cov Ntsuas Hluav Taws Xob

Cov ntsuas hluav taws xob electromagnetic(tseem hu ua mag meters) yog siv dav hauv ntau yam lag luam los ntsuas qhov ntws ntawm cov kua dej conductive. Cov flow meters no ua haujlwm raws li Faraday Txoj Cai ntawm electromagnetic induction, uas tsis tas yuav muaj cov khoom txav mus los, muab qhov tseeb siab thiab kev ntseeg siab hauv kev ntsuas cov kua dej ntws. Ib qho tseem ceeb ntawm lub electromagnetic flow meter yog cov khoom siv hauv pem teb, uas ua haujlwm los tiv thaiv sab hauv ntawm lub meter thaum ua kom ntseeg tau tias lub cuab yeej ua haujlwm zoo. Kev xaiv cov khoom siv hauv pem teb cuam tshuam ncaj qha rau kev ua tau zoo, kev ruaj khov, thiab kev haum ntawm lub flow meter rau ntau yam kev siv. Hauv tsab xov xwm no, peb yuav tshawb nrhiav ntau yam khoom siv hauv pem teb siv hauv electromagnetic flow meters thiab lawv cuam tshuam li cas rau lub meter ua haujlwm.

Cov ntaub ntawv hauv pem teb yog dab tsiCov Ntsuas Hluav Taws Xob?

Cov ntaub ntawv sab hauv yog siv los txheej sab hauv ntawm lub raj ntsuas dej kom tiv thaiv lub ntsuas ntawm cov tshuaj lom neeg, kev sib txhuam, thiab qhov kub thiab txias heev. Cov ntaub ntawv sab hauv zoo ua kom muaj kev ntsuas raug thiab ua kom lub ntsuas ntev dua los ntawm kev tiv thaiv kev puas tsuaj los ntawm cov kua dej corrosive lossis cov xwm txheej ua haujlwm hnyav.

Cov Yam Tseem Ceeb Rau Kev Xaiv Cov Khoom Siv Sab Hauv

Thaum xaiv cov khoom siv sab hauv rau lub ntsuas hluav taws xob electromagnetic, ntau yam yuav tsum tau xav txog:

• Kev Tiv Thaiv TshuajCov khoom siv yuav tsum tiv taus cov kua dej uas ntsuas tau, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj cov tshuaj lom neeg lossis cov kua qaub.
• Kev Tiv Thaiv Kev Sib TxhuamYog tias cov kua dej muaj cov khoom khov lossis cov slurries, cov khoom siv uas tiv taus kev sib txhuam siab yog qhov tsim nyog.
• Kev Tiv Thaiv Kub: Cov khoom siv hauv ob sab yuav tsum tiv taus qhov kub thiab txias ntawm daim ntawv thov.
• Kev Sib Piv ntawm Cov Kua: Lub txheej yuav tsum sib xws nrog hom kua dej uas ntsuas, txawm tias nws yog corrosive heev, abrasive, lossis high-pressure.

Cov Khoom Siv Hauv Sab Hauv Rau Cov Ntsuas Hluav Taws Xob

Cov Khoom Siv Hauv Sab Hauv	Cov Khoom	Cov ntawv thov	Cov txiaj ntsig	Cov kev txwv
