Ngiyazibuza ukuthi ubonile yini ukuthi isihluthulelo sokukhetha imishini yokuxuba i-asphalt sisekunqunyweni kohlobo lwayo lwe-impeller. Ngaphezu kokucabangela izimo zokuklama ukuxuba, isipiliyoni sidlala indima ebalulekile. Yiziphi izidingo okufanele izigwedlo zemishini yokuxuba i-asphalt yakhelwe ngokuya ngazo?
Kunezici eziningi ezidinga ukucatshangelwa, hhayi kuphela izici ze-shear-circulation of the impeller; ukuguquguquka kwe-impeller ku-viscosity yezinto; iphethini yokugeleza eyenziwe yi-impeller, njll., kodwa futhi izici zama-impellers ahlukahlukene zidinga ukuhlanganiswa nezinhloso ezahlukene zokuxuba. Ake sixoxe ngodaba lokukhetha i-impeller.
Ngaphezu kwalokho, okuqukethwe okuyinhloko kokukhethwa kwemodeli akukhona nje ukuzimisela kohlobo, kodwa futhi impahla ngemva kokunquma uhlobo. Isibonelo, i-carbon steel, insimbi engagqwali, ingilazi-lined, njll. ingakhethwa, ngokuvamile ngokusekelwe ekusebenzeni kwezinto zokuxuba. nquma umphumela mayelana nalokhu.
