Embonini yephepha, ukusetshenziswa kahle kwe-pulp kubalulekile ekugcineni amazinga okukhiqiza asezingeni eliphezulu. Ukulinganisa okunembile nokulawula ukugeleza kwe-slurry kubalulekile ukuqinisekisa ukwakheka kweshidi okuhle kakhulu nokunciphisa imfucuza. Ukuze kufezwe lo mgomo, abakhiqizi abaningi bephepha baphendukela kubuchwepheshe obuthuthukisiwe njenge-Doppler flow meter ukuze bathuthukise izinqubo zabo zokufaka i-slurry.
I-Doppler flow meter iyithuluzi lokulinganisa ukugeleza elingangenisi umswakama elisebenzisa ubuchwepheshe be-ultrasonic ukukala ukugeleza koketshezi, okuhlanganisa ne-pulp. Ngokukhipha amaza omsindo avame kakhulu ku-slurry nokuhlaziya ukushintsha kwemvamisa yamaza abonakalisiwe, amamitha okugeleza e-Doppler anganquma ngokunembile izinga lokugeleza kanye nomthamo we-slurry ngaphandle kokuthintana ngqo nezinto.
Enye yezinzuzo eziyinhloko zokusebenzisa amamitha okugeleza e-Doppler ekusetshenzisweni kwe-slurry yokwenza iphepha yikhono lawo lokuhlinzeka ngedatha yokugeleza ngesikhathi sangempela, okuvumela opharetha ukuthi baqaphe futhi balungise ukugeleza kwe-slurry njengoba kudingeka. Leli zinga lokulawula libalulekile ekugcineni ikhwalithi yephepha ehambisanayo kanye nokunciphisa isikhathi sokungasebenzi komkhiqizo.
Ngaphezu kwalokho, amamitha okugeleza e-Doppler ayakwazi ukulinganisa ukugeleza kwe-slurry ngaphansi kwezimo ezinzima, njengokushisa okuphezulu kanye nezindawo ezihudulayo, okwenza afaneleke kahle ezidingweni ezidingakalayo zenqubo yokwenza iphepha. Ukungahlaseli kwawo kusho nokuthi awaphazamisi ukugeleza kwe-slurry, okuqinisekisa ukukhiqizwa okuqhubekayo nokungaphazanyiswa.
Ngokuhlanganisa amamitha okugeleza e-Doppler ezinhlelweni zabo zokufaka i-pulp, abakhiqizi bangafinyelela ukusebenza kahle okukhulu kanye nokunemba ezinqubweni zabo zokukhiqiza. Idatha yokugeleza yesikhathi sangempela enikezwa yilezi zinsimbi ivumela ukulawulwa okunembile kokusetshenziswa kwe-slurry, okuholela ekwakhekeni kweshidi elithuthukisiwe kanye nokunciphisa imfucuza yezinto ezibonakalayo.
Ngaphezu kokuthuthukisa ukusebenza kahle, amamitha okugeleza e-Doppler nawo ahlinzeka ngokonga izindleko ngokunciphisa ukusetshenziswa kwezinto zokusetshenziswa kanye nokunciphisa ukusetshenziswa kwamandla. Njengoba benekhono lokulinganisa ngokunembile ukugeleza kwe-slurry, abakhiqizi bangenza ngcono izinqubo zabo zokukhiqiza futhi banciphise ukusetshenziswa kwezinsiza okungadingekile.
Ngaphezu kwalokho, ukukhishwa kwedatha okuvela kumitha yokugeleza kwe-Doppler kungahlanganiswa nezinhlelo zokulawula ezikhona, okuhlinzeka ngesibukezo esiphelele senqubo yokufaka isicelo se-slurry. Lokhu kuhlanganiswa kwenza kube lula ukuqapha okungenazinkinga, okuvumela opharetha ukuthi benze izinqumo ezinolwazi ukuze bathuthukise ukusebenza kahle kokukhiqiza.
Ngamafuphi, ukusetshenziswa kobuchwepheshe be-Doppler flowmeter ekusetshenzisweni kwe-pulp kunikeza izinzuzo ezibalulekile kubakhiqizi bephepha. Ngokunikeza idatha yokugeleza enembile, yesikhathi sangempela kanye nokuvumela ukulawulwa okunembile kwezicelo ze-slurry, amamitha okugeleza e-Doppler asiza ukuthuthukisa ikhwalithi yephepha, ukunciphisa imfucuza kanye nokusebenza kahle kokusebenza. Njengoba imboni yephepha iqhubeka nokuthuthuka, ukwamukelwa kobuchwepheshe obuthuthukisiwe njenge-Doppler flow metres kuzodlala indima ebalulekile ekukhuthazeni ukusungula izinto ezintsha kanye nentuthuko esimeme embonini.
