Lub impeller yog lub plawv ntawm tus kiv cua centrifugal. Cov chaw ua haujlwm sib txawv thiab cov xwm txheej sib txawv ntawm qhov yuav tsum tau ua ntawm hom impeller. Raws li lub kaum sab xis ntawm lub qhov hluav taws xob impeller, hom impeller tuaj yeem muab faib ua peb pawg: pem hauv ntej- nkhaus, radial, thiab rov qab- nkhaus.
Rau pem hauv ntej- nkhaus hniav: Cov hniav qhov hluav taws xob lub kaum sab xis 2> 90 degree, ua rau lub qhov hluav taws xob siab dua tab sis qis dua. Rau pem hauv ntej- cov hniav nkhaus zoo li khaws cov impurities thiab nplai ntawm cov hniav impeller. Lawv tau dav siv nyob rau hauv cov cheeb tsam nrog nruab nrab airflow tab sis siab xav tau. Cov hniav feem ntau nqaim thiab ntau dua. Common forward-cov qauv kiv cua nkhaus suav nrog 9-19 series thiab 9-26 series kiv cua siab.
Radial hniav: Lub qhov hluav taws xob lub kaum sab xis 2=90℃. Radial hniav muaj cov qauv yooj yim thiab cov nqi tsim khoom qis, nrog rau qhov tsis sib xws ntawm pem hauv ntej - nkhaus thiab rov qab - hom nkhaus. Txawm li cas los xij, lawv cov efficiency qis dua. Vim lawv tsis kam scaling, lawv tau siv dav hauv mines thiab ib puag ncig nrog cov hmoov av siab.
Rov qab- cov hniav nkhaus: Cov hniav qhov hluav taws xob lub kaum sab xis 2 < 90℃. Hom impeller no muaj huab cua ntim loj thiab tsis tshua muaj siab, tab sis kev ua haujlwm siab heev. Hauv Suav teb, cov kiv cua centrifugal nrog rov qab dav dav- nkhaus impellers tuaj yeem ua tiav qhov ua tau zoo ntawm 80%-90%, yog li lawv tau siv dav. Ntxiv mus, vim lawv cov yam ntxwv tsis yog fouling, lawv tau siv dav hauv kev lag luam hluav taws xob, metallurgy, tshuaj lom neeg kev lag luam, thiab cov khoom siv hauv tsev.
