Into ebaluleke kakhulu ohlelweni lwe-pulping ukulawula izinga lokugeleza kwe-pulp. Faka i-electromagnetic flowmeter lapho uphuma khona iphampu ye-slurry kuhlobo ngalunye lwe-pulp, futhi ulungise ukugeleza kodaka ngevalvu elawulayo ukuze uqinisekise ukuthi udaka ngalunye luyalungiswa ngokuvumelana nesilinganiso esidingwa inqubo, futhi ekugcineni uzuze isilinganiso esizinzile nesifanayo sodaka.
Uhlelo lokuhlinzeka ngodaka luhlanganisa lezi zixhumanisi ezilandelayo: 1. inqubo yokuhlakazeka; 2. inqubo yokushaywa; 3. inqubo yokuhlanganisa.
Enkambweni yokuhlakazeka, i-flowmeter ye-electromagnetic isetshenziselwa ukulinganisa ngokunembile izinga lokugeleza kwe-slurry ehlakazekile ukuze kuqinisekiswe ukuzinza kwe-slurry ehlakazekile futhi kuqinisekiswe ukuzinza kwe-slurry ekushayeni okulandelayo; ekushayeni, i-electromagnetic flowmeter kanye ne-valve elawulayo I-loop yokulungisa i-PID yakheka ukuze kuqinisekiswe ukuzinza kokugeleza kwe-slurry kumshini wokugaya, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwe-disc mill kanye nokuzinzisa izinga lokudonswa kwe-slurry, ngaleyo ndlela kuthuthukiswe izinga lokushaywa;
Lezi zimo ezilandelayo kufanele zihlangatshezwe ngesikhathi sokuxuba:
I-1) Ingxenye kanye nokugxila kwe-slurry kufanele kube njalo, futhi ukuguquguquka akufanele kudlule u-2% (inani lokuguquguquka lisekelwe ezidingweni zephepha eliqediwe);
I-2) Udaka olulethwa emshinini wephepha kufanele luzinze ukuze kuqinisekiswe ukutholakala okuvamile komshini wephepha;
3) Gcina inani elithile le-slurry ukuze uvumelane nezinguquko zejubane lomshini wephepha nezinhlobonhlobo.
Inzuzo:
?Ingalungiselelwa ngezinhlobonhlobo zezinto ezihambisana nezidingo zenqubo
?I-diameter egcwele ngaphandle kokwehla kwengcindezi kuyo yonke imitha
?I-obstruction-less (i-fiber ayikhuphuki kumitha)
?Ukunemba okuphezulu kanye nesivinini esikhulu sokuphendula kuhlangabezana nezidingo eziqinile zesilinganiso
Inselelo:
izinga lokushisa eliphezulu lenqubo kanye nokuhuzuka ngenxa yokuqinile kwesitoko se-pulp kunikeza izinselele eziyingqayizivele.
I-Liner Materials: sebenzisa kuphela ama-Teflon liners aqinile aphezulu.
Izinto ze-Electrode: Ngokusho kwe-medium
Ukufakwa
Lapho ukala i-slurry, kungcono ukuyifaka ngokuqondile, futhi uketshezi lugeleza lusuka phansi luye phezulu. Lokhu akuqinisekisi nje kuphela ukuthi ishubhu yokulinganisa igcwaliswa ngendawo elinganisiwe, kodwa futhi kugwema ukushiyeka kokuhuzuka kwendawo engxenyeni engezansi ye-flowmeter kagesi kanye nemvula yesigaba esiqinile ngamanani okugeleza aphansi lapho efakwe ngokuvundlile.
