Cov khoom siv rau lub impeller yuav tsum raug xaiv raws li cov khoom siv, qhov nruab nrab ua haujlwm, thiab qhov chaw ua haujlwm; Cov khoom siv xws li cam khwb cia hlau, carbon hlau, stainless hlau, thiab txhuas alloy. Raws li tus qauv kev ua haujlwm, cam khwb cia hlau impellers-tus yam ntxwv los ntawm tus nqi qis, yooj yim ntawm machining, thiab hnav tsis kam-yog haum rau cov kiv cua thiab cov twj tso kua mis. Rau cov khoom siv uas xav tau lub zog siab dua, cov khoom siv xws li carbon steel yuav raug xaiv los ua kom ntseeg tau tias kev ua haujlwm ntev.
Stainless hlau yog lwm yam khoom siv rau impeller manufacturing, feem ntau yog siv rau hauv daim ntawv thov uas yuav tsum tau muaj corrosion kuj. Piv txwv li, thaum thauj corrosive kua los yog ua hauj lwm nyob rau hauv ib puag ncig nrog high humidity los yog raug tshuaj lom neeg ua hauj lwm, stainless hlau impellers pab txo qhov cuam tshuam ntawm xeb thiab corrosion ntawm cov khoom ua hauj lwm. Txij li cov qib sib txawv ntawm stainless hlau sib txawv hauv kev tiv thaiv corrosion, lub zog, thiab tus nqi, cov qib tshwj xeeb yuav tsum raug xaiv raws li qhov kev ua haujlwm tiag tiag.
Aluminium alloy impellers kuj tau siv dav hauv cov kiv cua thiab cov cuab yeej siv ceev ceev. Due to its low density, aluminum alloy reduces the impeller's weight while maintaining sufficient mechanical strength, thereby lowering rotational inertia and reducing the load on the motor. Rau cov khoom siv ceev ceev, impeller qhov hnyav thiab qhov sib npaug ncaj qha cuam tshuam rau kev ua haujlwm ruaj khov; Yog li ntawd, xaiv cov khoom yuav tsum sib npaug zog thiab corrosion kuj nrog rau qhov hnyav thiab machinability.
Ntxiv rau cov hlau, impellers rau cov cuab yeej tshwj xeeb tuaj yeem tsim los ntawm fiberglass-reinforced yas (FRP), engineering plastics, lossis lwm yam khoom siv sib xyaw. Cov ntaub ntawv no muaj qhov zoo xws li qhov hnyav thiab corrosion kuj, ua rau lawv haum rau cov kev siv tshwj xeeb hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, lossis kev thauj cov roj tshwj xeeb. Thaum xaiv cov khoom siv impeller, ib qho yuav tsum tsis txhob tsom rau tus nqi nkaus xwb; Hloov chaw, kev ntsuam xyuas dav dav-xav txog cov khoom ntawm qhov nruab nrab, qhov kub thiab txias, kev sib hloov ceev, siab, hnav tsis kam, thiab cov cuab yeej siv lub neej-yog qhov tseem ceeb los xaiv cov khoom siv uas haum rau qhov chaw ua haujlwm.
