Kuchenesa ma electrode kunowanzoshandiswa nenzira dzinotevera:

1. Nzira dzemagetsi

Kune zviitiko zvemagetsi zve electrode yesimbi mu electrolyte fluid. Zvichienderana nepfungwa ye electrochemistry, pane munda wemagetsi wepakati pe electrode ne fluid, uye kubatana pakati pe electrode ne fluid kunokonzerwa ne double electric layer iripo pakati pe electrode ne fluid. Chidzidzo che electric field che interface pakati pe electrodes ne fluids chakaona kuti ma molecule, maatomu kana ma ions ezvinhu ane rich or poor adsorption phenomenon, uye chakaona kuti ma anions mazhinji e inorganic zvinhu zvinoshanda kunze zvine mitemo ye typical ion adsorption, nepo inorganic cations dzisina basa rakawanda. Saka, electrode yekuchenesa electrochemical inongotarisa mamiriro e anion adsorption. Adsorption ye anion yakabatana zvakanyanya ne electrode potential, uye adsorption inonyanya kuitika mu potential scale iyo yakagadziriswa kupfuura zero charge potential, kureva, electrode surface ine charge yakasiyana. Pamusoro peelectrode ine chaji imwecheteyo, kana huwandu hwechaji yasara hwakakura zvishoma, kudzoserwa kwemagetsi kwakakura kupfuura simba re adsorption, uye anion inobviswa nekukurumidza, inova ndiyo musimboti wekuchenesa kwemagetsi.

2. Kubviswa kwemuchina

Nzira yekuchenesa michina ndeyekupedzisa kuchenesa electrode kuburikidza nechimiro chakakosha chemuchina chiri paelectrode. Iye zvino kune marudzi maviri:

Imwe nzira ndeyekushandisa chikwepa chemagetsi, chakagadzirwa nesimbi isina ngura ine mubato mutete wechikwepa, kuburikidza neelectrode isina chinhu kuti chibude, mubato mutete neelectrode isina chinhu pakati pechisimbiso chemagetsi kudzivirira kubuda kwemidziyo, saka chakagadzirwa nechikwepa chemagetsi. Kana mubato mutete wapindurwa kubva kunze, chikwepa chinotenderedzwa chakanangana nendege yemagetsi, chichibvisa tsvina. Chikwepa chinogona kukwerwa nemaoko kana otomatiki ne mubato mutete unofambiswa nemota. Mugero wemagetsi wemumba weJiangsu Shengchuang's scraper type electromagnetic flowmeter une basa rakadaro, uye basa racho rakagadzikana uye kushanda kwacho kuri nyore.

Imwe ibhurashi rewaya rinoshandiswa kubvisa tsvina muelectrode ine tubular, uye shaft yacho yakaputirwa ne "O" ring yakavharwa kudzivirira kubuda kwemvura. Muchina uyu wekuchenesa unoda kuti munhu akwanise kudhonza bhurashi rewaya kuti achenese electrode, mashandiro acho haasi nyore, hapana electromagnetic flowmeter iri nyore kushandisa.

3. Nzira yekuchenesa yeUltrasonic

Voltage ye ultrasonic ye45~65kHz inogadzirwa ne ultrasonic generator inowedzerwa ku electrode, kuitira kuti simba re ultrasonic rive pamusoro pekubatana pakati pe electrode ne medium, uye ipapo ultrasonic inogona kupwanywa kuti iwane chinangwa chekuchenesa.

Iyi ndiyo nzira yekuchenesa electrode ye electromagnetic flowmeter, kuitira kuti isakanganise kushandiswa, asiwo kuvandudza kushanda zvakanaka kwebasa re electromagnetic flowmeter.
