Electromagnetic flowmeter zero instability check process:

Electromagnetic flowmeter zero instability check process:

1, kushandiswa kwevhavha kwenguva yakareba kana tsvina yemvura kuita kuti valve ivhare nyaya dzisina kukwana dzinowanzosangana, kunyanya mavharuvhu makuru.Chimwe chikonzero chinowanzoitika ndechekuti mita yekuyerera ine matavi akati wandei kuwedzera kune pombi huru, uye valve yematavi aya inokanganwa kana kuregeredzwa kuvhara.

2, iyo fluid conductivity inoshanduka kana isiri pakati, iyo zero inoshanduka pakuzorora, uye inobuda inozununguka kana ichishanda.Naizvozvo, nzvimbo yemamita ekuyerera inofanirwa kunge iri kure nenzvimbo yejekiseni kana kudzika kwepombi kemikari mhinduro chikamu, uye inoyerera sensor inoiswa zvirinani kumusoro kwenzvimbo idzi.

3, nekuti iyo yemukati madziro ekumusoro kuyera uye electrode kusvibiswa mwero haigone kuzara uye symmetrical, yakaparadza yekutanga zero kuseta kwekuenzana.Matanho ekurapa ndeekubvisa tsvina uye yakaunganidzwa chiyero chepamusoro;Kana iyo zero shanduko isiri yakakura, unogona zvakare kuedza kusetazve zero.

4, shanduko yechimiro chemidziyo yemagetsi padhuze nekuyerera sensor (senge kuwedzera kwekudonha kwazvino) inoumba shanduko mukugona kwevhu, izvo zvinokonzeresa kuti electromagnetic flowmeter zero shanduko.Dzimwe nguva mamiriro ezvakatipoteredza ari nani, uye electromagnetic flowmeter inogona kushanda zvakajairwa pasina kudzika pasi, asi kana nzvimbo yakanaka isipo, dambudziko rezviridzwa rinoonekwa.

5. Tarisa chati inoyerera.Kudzikisira kusungirirwa kwechiratidzo chechiratidzo kuchaita kuti zero kusagadzikana.Chikonzero chikuru chekudonha kwekudzivirira kwechiratidzo chedunhu kunokonzerwa nekudzikiswa kwekudzikiswa kwechikamu che electrode, kuiswa chisimbiso kwewaya yekubatanidza hakuna kuomarara, uye hunyoro hweacid fog kana guruva rehupfu rinopinda mubhokisi rejunction bhokisi kana tambo yekuchengetedza tambo, kuitira kuti iyo insulation ideredze.

Kana dambudziko risati ragadziriswa, pls taura nesu kuti tikutsigire.
