Kuyeretsa ma electrode nthawi zambiri kumagwiritsidwa ntchito m'njira zotsatirazi:

Kuyeretsa ma electrode nthawi zambiri kumagwiritsidwa ntchito m'njira zotsatirazi:

1. Njira zamagetsi

Pali zochitika zamagetsi za electrode yachitsulo mu electrolyte fluid. Malinga ndi mfundo ya electrochemistry, pali munda wamagetsi wolumikizana pakati pa electrode ndi madzi, ndipo kulumikizana pakati pa electrode ndi madzi kumachitika chifukwa cha zigawo ziwiri zamagetsi zomwe zilipo pakati pa electrode ndi madzi. Kafukufuku pa munda wamagetsi wa kulumikizana pakati pa ma electrode ndi madzi adapeza kuti mamolekyu, maatomu kapena ma ayoni azinthu ali ndi vuto la adsorption lolemera kapena losauka pamalo olumikizirana, ndipo adapeza kuti ma anion ambiri osapangidwa ndi zinthu ndi zinthu zomwe zimagwira ntchito kunja zomwe zimakhala ndi malamulo wamba a adsorption a ion, pomwe ma cations osapangidwa ndi zinthu alibe ntchito yodziwika bwino. Chifukwa chake, electrode yoyeretsa ya electrochemical imangoganizira momwe anion imadsorption imakhalira. Adsorption ya anion imagwirizana kwambiri ndi electrode potential, ndipo adsorption imachitika makamaka mu potential scale yomwe imakonzedwa bwino kuposa zero charge potential, kutanthauza, pamwamba pa electrode yokhala ndi charge yosiyana. Pamwamba pa elekitirodi yokhala ndi chaji yomweyi, pamene kuchuluka kwa chaji yotsalayo kuli kwakukulu pang'ono, mphamvu ya electrostatic repulsion imakhala yayikulu kuposa mphamvu ya adsorption, ndipo anion imachotsedwa mwachangu, yomwe ndi mfundo yoyeretsera ya electrochemical.

2. Kuchotsa makina

Njira yoyeretsera makina ndiyo kutsiriza kuyeretsa ma electrode kudzera mu kapangidwe ka makina ka chipangizocho pa electrode. Tsopano pali mitundu iwiri:

Chimodzi mwa izi ndi kugwiritsa ntchito makina oskera, opangidwa ndi chitsulo chosapanga dzimbiri chokhala ndi shaft yopyapyala ya choskera, kudzera mu elekitirodi yopanda kanthu kuti atuluke, shaft yopyapyala ndi elekitirodi yopanda kanthu pakati pa chisindikizo cha makina kuti apewe kutuluka kwa media, zomwe zimapangidwa ndi makina oskera. Pamene shaft yopyapyala yatembenuzidwa kuchokera kunja, choskeracho chimatembenuzidwa motsutsana ndi ndege yamagetsi, ndikuchotsa dothi. Choskeracho chikhoza kuskera pamanja kapena chokha ndi shaft yopyapyala yoyendetsedwa ndi mota. Choyezera kuyenda kwa maginito chamagetsi cha Jiangsu Shengchuang's scraper type electromagnetic flowmeter chili ndi ntchito yotereyi, ndipo ntchito yake ndi yokhazikika ndipo ntchito yake ndi yosavuta.

China ndi burashi ya waya yomwe imagwiritsidwa ntchito kuchotsa dothi mu electrode yozungulira, ndipo shaft imakulungidwa mu mphete yotsekedwa ya "O" kuti madzi asatuluke. Zipangizo zotsukira izi zimafuna munthu woti azikoka burashi ya waya nthawi zambiri kuti ayeretse electrode, ntchito yake si yabwino kwambiri, palibe choyezera magetsi chosavuta kugwiritsa ntchito.

3. Njira yoyeretsera ya akupanga

Mphamvu yamagetsi ya 45 ~ 65kHz yopangidwa ndi jenereta ya ultrasonic imawonjezeredwa ku electrode, kotero kuti mphamvu yamagetsi imayikidwa pamwamba pa kukhudzana pakati pa electrode ndi sing'anga, kenako ultrasound imatha kuphwanyidwa kuti ikwaniritse cholinga choyeretsa.

Njira yoyeretsera ma electrode pogwiritsa ntchito electromagnetic flowmeter ndi iyi, kuti isalepheretse kugwiritsa ntchito, komanso kuti iwonjezere kugwira ntchito bwino kwa electromagnetic flowmeter.
