Ama-slurry, njengezingxube eziyinkimbinkimbi zoketshezi nezinhlayiya eziqinile, abalulekile ezimbonini ezifana nezezimayini, ukucubungula amakhemikhali, ukwelashwa kwamanzi amdaka, kanye nokwakha. Ukulinganisa ukugeleza okunembile kwama-slurry kubalulekile ekwenzeni ngcono izinqubo zokukhiqiza, ukulawula izindleko, kanye nokuqinisekisa ukuphepha kokusebenza. Phakathi kobuchwepheshe obuhlukahlukene bokulinganisa ukugeleza, ama-flowmeter kagesi (ama-EMF) avelele ngezinzuzo zawo ezihlukile ekubhekaneni nezinselele ezibangelwa ama-slurry abrasive, viscous, kanye nama-high-solids-content.
Isimiso sokusebenza sama-EMF sisekelwe kuMthetho kaFaraday wokungeniswa kwe-electromagnetic. Lapho i-slurry eqhubayo igeleza ensimini yamagnetic ekhiqizwa yi-coils yemitha, ibangela amandla e-electromotive (EMF) alingana nejubane lokugeleza, amandla ensimu yamagnetic, kanye nebanga eliphakathi kwama-electrode. Le voltage ebangelwayo itholwa ngama-electrode afakwe odongeni lwepayipi, futhi i-flowmeter iyiguqula ibe ukufundwa kwesilinganiso sokugeleza okunembile. Okuphawulekayo ukuthi ama-EMF alinganisa izinga lokugeleza kwevolumu ngqo, angathinteki yi-slurry viscosity, ubuningi, noma ukushintshashintsha kwezinga lokushisa—izinto ezibalulekile eziphazamisa ezinye izinhlobo zamamitha.
Inzuzo eyinhloko yama-EMF ekusetshenzisweni kwe-slurry ukwakheka kwawo okungaphazamisi noma kwe-full-bore. Ama-EMF e-full-bore anesakhiwo sepayipi esiqondile esingenazo izingxenye noma izithiyo ezihambayo, okususa ingozi yokuvaleka, ukuguguleka, noma ukulahlekelwa yingcindezi okubangelwa yizinhlayiya ze-slurry. Lo mklamo uqinisekisa ukugeleza kwe-slurry okungavimbelwe futhi unciphisa izidingo zokulungisa, inzuzo ebalulekile ye-slurry ekhuhlayo njenge-tailings yezimayini noma izingxube zekhonkrithi ezonakalisa kalula ama-flowmeter emishini.
Ama-EMF aphinde abonise ukuzivumelanisa nezimo ezinhle kakhulu nezakhiwo ezahlukahlukene ze-slurry. Asebenza ngokuthembekile ngama-slurry aqukethe uketshezi oluqhuba umoya (isb., ama-slurry asekelwe emanzini) kanye nezinhlayiya eziqinile ezinobukhulu obuhlukahlukene, kusukela kuma-sediment amancane kuya kuma-coarse aggregates. Amamodeli e-EMF athuthukisiwe afakwe ama-electrode amelana nokugqwala (enziwe ngezinto ezifana ne-Hastelloy, i-titanium, noma i-tantalum) kanye nama-liners (irabha, i-PTFE, noma i-polyurethane), okuwenza akwazi ukumelana nezimo ezinzima ze-slurry, okuhlanganisa amazinga okushisa aphezulu kanye nokugqwala kwamakhemikhali.
Emisebenzini yezimboni, ama-EMF asetshenziswa kabanzi emikhakheni yokuphatha udaka. Ezimayini, aqapha ukugeleza kodaka lwamaminerali (isb., ubhedu, udaka lwensimbi) ngesikhathi sokukhipha nokucubungula, aqinisekise ukuthuthwa kwe-ore okuphumelelayo kanye nokulawulwa kwenqubo. Izitshalo zokuhlanza amanzi amdaka zisebenzisa ama-EMF ukukala ukugeleza kodaka lwedaka, zisekela izinqubo zokususa amanzi nokulahla udaka ngenkathi zihambisana nemithethonqubo yezemvelo. Embonini yokwakha, alinganisa ngokunembile ukugeleza kodaka lwekhonkrithi ukuze alondoloze izilinganiso zokuxuba nokuqinisekisa ikhwalithi yesakhiwo.
Ukuze kukhuliswe ukunemba kokulinganisa, kubalulekile ukucabanga ngezinto eziningana zokusebenza. I-slurry kumele ibe nokuqhuba okwanele; ama-slurry angaqhubi (isb., izingxube ezisekelwe ku-oyela) adinga ukulungiswa kwangaphambi kokwelashwa noma amamitha ahlukile. Ukufakwa okufanele, kufaka phakathi ubude obufanele bepayipi eliqondile elingenhla/phansi, kugwema ukuphazamiseka kokugeleza. Ukugcinwa njalo, njengokuhlanza ama-electrode nokuhlola ama-liner ukuthi agugile, kulondoloza ukuthembeka kokulinganisa. Ukulinganisa ngokumelene nezindlela ezijwayelekile (isb., amathangi e-volumetric) nakho kunconywa ezisetshenzisweni ezibalulekile.
Njengoba izimboni ziphishekela ukusebenza kahle nokunemba okuphezulu, ama-EMF ayaqhubeka nokuthuthuka ngobuchwepheshe obuhlakaniphile, njengokucubungula isignali yedijithali kanye nokudluliswa kwedatha engenantambo, okuthuthukisa ukuqapha ngesikhathi sangempela kanye namakhono okulawula kude. Amandla abo okusingatha izimo ezinzima ze-slurry, kuhlanganiswe nokunemba okuphezulu kanye nokugcinwa okuphansi, kwenza ama-flowmeter kagesi abe ithuluzi elibalulekile lokulinganisa ukugeleza kwe-slurry yesimanje, okuqhuba ukusebenza kahle kuzo zonke izimboni ezibalulekile.
