Tus impeller yog qhov tseem ceeb ntawm cov twj tso kua mis centrifugal, ib txwm ua los ntawm cov hlau cam khwb cia. Cov hniav me ntawm cov impeller ua lub luag haujlwm tseem ceeb, thiab impeller tus qauv thiab qhov loj me cuam tshuam nrog lub twj tso kua mis. Cov neeg tsis tuaj yeem siv feem ntau yuav raug cais ua ob hom:Ib Leeg - suctionthiabOb Chav - suction.

Kaw Impeller
Muaj cov hniav txuas ntawm nruab nrab ntawm sab hauv ntej thiab nram qab.
Muab cov efficiency highsiciency tab sis yog qhov nyuaj dua los tsim khoom.
Feem ntau dav siv nyob rau hauv centrifugal twj.
Haum rau huv si, qis {{- viscosity cov kua (piv txwv li dej, tshuaj lom neeg) tsis muaj tshuaj lom.

Qis dua kev ua tau tab sis tuaj yeem txhim kho nrog cov khoom ntiag tug tau.
Tsheb Semi -} qhib:Tsim ntawm cov hniav thiab ib sab pem hauv ntej.
Kev ua tau zoo sib xws rau kaw cov impellers vim tias tau hnav cov nplhaib sib xws.
Cov hniav txuas kuj tseem ua haujlwmrov qab vanes lossis cov neeg ua haujlwm impellers, txhim kho kev sib khi.

Haum rau cov kua uas muaj cov khib nyiab tshem tawm lossis cov fibers.
Txhawb siv hauv petrochemical twj rau dej thiab cov kua zoo sib xws.
Qhib impeller
Muaj tsuas yog cov hniav nrog kev txhawb nqa tus tav (tsis muaj sab pem hauv ntej lossis sab nraub qaum).
Feem ntau muaj tsawg dua li siav (2-5).
Cov khoom qis dua, feem ntau yog siv rau qhov siab - viscosity los yog slurry- zoo li kua.
Centrifugal twj tso kua mis impellers feem ntau featurerov qab - nkhaus nkhaus, uas tuaj yeem yog:
Cylindrical (ncaj)- Yooj yim tab sis tsis tshua muaj peev xwm.
Twisted (3D nkhaus)- Txo cov hniav ntsuas hluav taws xob, txhim kho kev sib txuas lus, thiab txhim kho cavitation tsis kam. Txawm li cas los xij, Twisted cov hniav yog ntau dua ua cov khoom thiab kim heev.

Welded impellersTau txais cov koob meej tau, tshwj xeeb tshaj yog rau corrosion -} tiv taus alloys (piv txwv li titanium) uas nyuaj rau cam khwb cia.
Welded impellers muaj cov ntsiab lus geometric zoo dua thiab ua tiav, txhim kho cov twj tso tawm ua haujlwm.
