1. Txiav txim seb puas yuav siv lub tshuab electromagnetic flowmeter raws li lub npe thiab cov khoom ntawm qhov ntsuas nruab nrab.
Faj seeb: Electromagnetic flowmeters tsuas yog ntsuas qhov ntws ntawm cov kua ua kua, thaum cov pa roj, roj thiab cov kua organic feem ntau tsis yog cov piv txwv ntawm cov kua hluav taws xob.
2. Txiav txim siab cov khoom siv electrode raws li qhov kev kawm ntawm cov khoom nruab nrab
Lus Cim: Lub tuam txhab feem ntau muab plaub hom electrodes, xws li stainless hlau, Hastelloy, titanium thiab tantalum. Cov electrode twg yuav tsum tau xaiv yuav tsum tau kuaj xyuas raws li cov khoom ntawm qhov nruab nrab.
3. Txiav txim siab seb puas yuav siv roj hmab lossis PTFE hauv ob sab phlu raws li qhov ntsuas kub nruab nrab
Lus Cim: Qhov ntsuas kub ntawm cov roj hmab yuav tsum tsis pub tshaj 80C;
Teflon kub kuj 150C, instant 180C kuj;
Cov dej phwj hauv nroog feem ntau siv cov roj hmab hauv ob sab phlu thiab stainless hlau electrodes
4. Raws li paub qhov nruab nrab siab, xaiv qhov flange specification ntawm lub meter lub cev.
Lus Cim: Qhov tshwj xeeb ntawm electromagnetic flange feem ntau yog thaum txoj kab uas hla yog los ntawm DN 10-250, qhov ntsuas siab ntawm flange tsawg dua lossis sib npaug rau 1.6Mpa;
Thaum txoj kab uas hla yog los ntawm DN {{0}}, lub flange ntsuas siab yog tsawg dua los yog sib npaug rau 1.0Mpa;
Thaum qhov tseeb siab ntawm qhov nruab nrab siab tshaj qhov sib npaug ntawm cov yeeb nkab txoj kab uas hla-siab, nws yog ib qho kev txiav txim tshwj xeeb, tab sis qhov siab tshaj plaws yuav tsum tsis pub tshaj 6.4Mpa.
5. Txiav txim siab qhov conductivity ntawm qhov nruab nrab
Lus Cim: (1) Cov conductivity ntawm electromagnetic flowmeter yuav tsum tsis txhob qis dua 5uS / cm
(2) Lub conductivity ntawm kais dej yog hais txog kaum mus rau pua pua ntawm us / cm. Feem ntau, boiler dej mos (deionized dej) yog conductive, thiab dej ntshiab (dej distilled heev) tsis conductive.
(3) Cov hluav taws xob conductivity ntawm cov roj, roj thiab cov kua organic feem ntau yog qis dua 5uS / cm, uas tsis yog-conductive.
