Electrode tu feem ntau yog siv raws li hauv qab no:

1. Electrochemical txoj kev

Muaj electrochemical phenomena ntawm hlau electrode nyob rau hauv cov kua electrolyte.Raws li lub hauv paus ntsiab lus ntawm electrochemistry, muaj qhov cuam tshuam hluav taws xob ntawm lub electrode thiab cov kua dej, thiab qhov cuam tshuam ntawm electrode thiab cov kua dej yog tshwm sim los ntawm ob txheej hluav taws xob uas twb muaj lawm ntawm cov electrode thiab cov kua dej.Txoj kev tshawb no ntawm cov hluav taws xob ntawm qhov sib txuas ntawm electrodes thiab cov kua dej tau pom tias cov molecules, atoms lossis ions ntawm cov khoom muaj nplua nuj lossis tsis zoo adsorption tshwm sim ntawm qhov sib cuam tshuam, thiab pom tias feem ntau inorganic anions yog cov khoom siv sab nraud nrog cov cai ion adsorption, thaum cov inorganic cations muaj me ntsis kev ua.Yog li ntawd, electrochemical tu electrode tsuas yog txiav txim siab qhov xwm txheej ntawm anion adsorption.Lub adsorption ntawm anion yog ze ze rau cov electrode muaj peev xwm, thiab cov adsorption feem ntau tshwm sim nyob rau hauv lub peev xwm teev uas yog kho ntau tshaj li pes tsawg lub peev xwm, uas yog, electrode nto nrog txawv nqi.Nyob rau saum npoo ntawm cov electrode nrog tib tus nqi, thaum cov nqi them ntxiv yog me ntsis loj dua, cov electrostatic repulsion ntau dua li cov adsorption quab yuam, thiab cov anion yog desorbed sai, uas yog lub hauv paus ntsiab lus ntawm electrochemical tu.

2. Kev tshem tawm tshuab

Txoj kev tu neeg kho tshuab yog ua kom tiav cov electrode tu los ntawm cov txheej txheem tshwj xeeb ntawm cov cuab yeej ntawm lub electrode.Tam sim no muaj ob hom:

Ib qho yog siv cov khoom siv tshuab scraper, ua los ntawm cov hlau tsis muaj steel nrog nyias ncej ntawm lub scraper, los ntawm cov hollow electrode coj tawm, lub nyias ncej thiab hollow electrode ntawm lub tshuab foob kom tsis txhob muaj kev tawm ntawm cov xov xwm, yog li tsim los ntawm cov tshuab scraper. .Thaum cov ncej nyias yog tig los ntawm sab nraud, lub scraper yog tig tawm tsam lub dav hlau hluav taws xob, tshem tawm cov av.Lub scraper tuaj yeem ua manually los yog txiav tawm nrog lub ntsej muag nyias uas tau tsav los ntawm lub cev muaj zog.Lub domestic electromagnetic flowmeter ntawm Jiangsu Shengchuang lub scraper hom electromagnetic flowmeter muaj xws li ib tug muaj nuj nqi, thiab cov muaj nuj nqi yog ruaj khov thiab lub lag luam yog yooj yim.

Lwm qhov yog cov hlau txhuam siv los tshem tawm cov av hauv cov tubular electrode, thiab cov ncej yog qhwv hauv lub nplhaib "O" kaw kom tsis txhob muaj cov kua dej tawm.Cov cuab yeej tu no xav tau ib tus neeg los feem ntau rub cov hlau txhuam los ntxuav cov electrode, kev ua haujlwm tsis yooj yim heev, tsis muaj qhov yooj yim scraper hom electromagnetic flowmeter.

3. Ultrasonic tu txoj kev

Lub ultrasonic voltage ntawm 45 ~ 65kHz generated los ntawm lub tshuab hluav taws xob ultrasonic yog ntxiv rau lub electrode, yog li ntawd lub zog ultrasonic yog concentrated nyob rau hauv kev sib cuag nto ntawm lub electrode thiab nruab nrab, thiab ces lub ultrasonic yuav crushed mus cuag lub hom phiaj ntawm tu.

Cov saum toj no yog cov electromagnetic flowmeter electrode tu txoj kev, thiaj li tsis mus cuam tshuam kev siv, tab sis kuj los txhim kho cov efficiency ntawm electromagnetic flowmeter ua hauj lwm.
