I-electromagnetic flowmeter iyisisetshenziswa esisetshenziswa ukukala ukugeleza koketshezi lwe-conductive.
Ngokungafani nama-flowmeters avamile, ama-flowmeter ka-electromagnetic asebenza ngokususelwe emthethweni ka-Faraday wokungeniswa kuka-electromagnetic futhi akala ukugeleza koketshezi oluqhutshwayo ngokusekelwe kumandla kagesi akhiqizwa lapho uketshezi lwe-conductive ludlula endaweni kazibuthe yangaphandle.
Isakhiwo se-electromagnetic flowmeter ikakhulukazi siqukethe uhlelo lwesekethe kazibuthe, umgudu wokulinganisa,ama-electrode, indlu, ulayini, kanye nesiguquli.
Isebenza kanjani?
1. Ukukhiqizwa kwenkundla kazibuthe
Lapho kusetshenziswa i-flowmeter, ikhoyili ka-electromagnetic ikhiqiza inkambu kazibuthe perpendicular eya lapho kugeleza khona uketshezi. Le nkundla kazibuthe izinzile futhi iyafana, iqinisekisa imiphumela yokulinganisa engaguquki.
2. Ukungeniswa kwamandla kagesi
Lapho uketshezi lwe-conductive lugeleza endaweni kazibuthe, luwela imigqa yamagnetic field. Ngokomthetho kaFaraday, lokhu kunyakaza kubangela i-voltage oketshezini. Ubukhulu bale voltage bulingana nezinga lokugeleza koketshezi.
3. Ukutholwa kwamandla kagesi
Ama-Electrode ashumekwe kushubhu lokugeleza athola amandla kagesi. Indawo yama-electrode ibalulekile; ngokuvamile zibekwe phezulu nangaphansi kwe-tube yokugeleza ukuze kuqinisekiswe ukufundwa okunembile kungakhathaliseki ukuthi ijika lokugeleza.
4. Ukucubungula isignali
Isignali ye-voltage etholiwe ithunyelwa kumthumeli, ocubungula ulwazi. I-transmitter iguqula i-voltage ibe isilinganiso sokugeleza, ngokuvamile esiboniswa ngamayunithi afana namalitha ngomzuzu (L/min) noma amalitha ngomzuzu (GPM).
5. Okukhiphayo:
Okokugcina, idatha yokugeleza ingaboniswa esikrinini, irekhodwe ukuze ihlaziywe ngokuzayo, noma idluliselwe kusistimu yokulawula yokuqapha nokulawula kwesikhathi sangempela.
Izinzuzo ze-electromagnetic flowmeter
Izinzuzo zama-flowmeters ka-electromagnetic ikakhulukazi zifaka ukukala okunemba okuphezulu, akukho ukulahleka kwengcindezi, isilinganiso sobubanzi obubanzi, ukumelana nokugqwala okuqinile, ububanzi bohlelo lokusebenza, impendulo ebucayi, ukufakwa okulula, ukucubungula isignali yedijithali, ukulwa nokuphazamiseka okuqinile, njll.
Ukusetshenziswa kwe-electromagnetic flowmeter
● Ukulungiswa kwamanzi namanzi angcolile: Gada ukugeleza kwesikhungo sokuhlanza ukuze uqinisekise ukuthotshelwa kwemithetho yemvelo.
● Ukucutshungulwa kwamakhemikhali: Kala ukugeleza koketshezi olubolayo noma lwe-viscous ekukhiqizeni amakhemikhali.
● Imboni yokudla neziphuzo: Qinisekisa ukukalwa okunembile kokugeleza koketshezi olunjengejusi, ubisi, nososo, okubalulekile ekulawuleni izinga.
● Ezemithi: Gada ukuhamba kwezithako ezisebenzayo nezincibilikisi enqubweni yokwenziwa kwemithi.
Siphinde sihlinzekeama-electrodes aphansi (amandandatho aphansi)ukuze isetshenziswe ezimeni lapho ama-flowmeter ka-electromagnetic adinga ukuqondiswa kwamanje, ukuqedwa kokuphazamiseka, nokuqinisekisa ubuqotho beluphu yesiginali.
