Inqubo yokuhlola ukungazinzi kwe-electromagnetic flowmeter:
1, ukusetshenziswa kwevalvu isikhathi eside noma ukungcola koketshezi ukwenza ivalvu ivalwe ingabi namacala angaphelele kuzovame ukuhlangatshezwana nakho, ikakhulukazi amavalvu amakhulu. Esinye isizathu esivamile ukuthi imitha yokugeleza inamagatsha amaningana ngaphezu kwepayipi eliyinhloko, futhi ivalvu yala magatsha ikhohliwe noma ayinakwa ukuyivala.
2, ukuhanjiswa koketshezi kuyashintsha noma akujwayelekile, u-zero uzoshintsha lapho uphumule, futhi umphumela uzozamazama uma usebenza. Ngakho-ke, indawo yemitha yokugeleza kufanele ibe kude nendawo yokujova noma phansi kwesigaba sempendulo yamakhemikhali epayipini, futhi inzwa yokugeleza ifakwe kangcono endaweni ephezulu yalezi zindawo.
3, ngoba ukukalwa kobuso bodonga lwangaphakathi kanye nezinga lokungcoliswa kwe-electrode akukwazi ukuphelela futhi kulingane, kwabhubhisa ukusethwa kokuqala kwe-zero yokulingana. Izindlela zokwelapha ziwukususa ukungcola kanye nesendlalelo sesikali esiqongelelwe; Uma ushintsho lwe-zero lungelukhulu, ungazama futhi ukusetha kabusha i-zero.
4, ushintsho esimweni semishini yamandla eduze kwenzwa yokugeleza (njengokwanda komsinga wokuvuza) lubangela ushintsho emandleni omhlaba, okuzophinde kubangele ushintsho lwe-electromagnetic flowmeter. Ngezinye izikhathi izimo zemvelo zingcono, futhi i-electromagnetic flowmeter ingasebenza ngokujwayelekile ngaphandle kokumisa, kodwa uma indawo enhle ingekho, inkinga yethuluzi izovela.
5. Hlola ishadi lokugeleza. Ukunciphisa ukufudumala kwe-loop yesignali kuzoholela ekungazinzini okungenalutho. Isizathu esiyinhloko sokuwa kokufudumala kwesekethe yesignali kubangelwa ukwehla kokufudumala kwengxenye ye-electrode, ukuvalwa koxhumano lwentambo akuqinile, futhi inkungu noma uthuli lwempuphu olunomswakama lungena ebhokisini lokuxhumanisa izinsimbi noma ungqimba lokulungisa ikhebula, ukuze ukufudumala kunciphe.
Uma inkinga ingakaxazululeki, sicela uxhumane nathi ukuze sikusekele.
