Lub twj tso kua mis impeller tsis ua haujlwm tuaj yeem tshwm sim los ntawm ntau yam, suav nrog kev tsim tsis zoo, kev tsim khoom tsis zoo, kev teeb tsa tsis raug, thiab kev ua haujlwm tsis raug. Qee qhov laj thawj feem ntau rau impeller tsis ua haujlwm suav nrog cavitation, yaig, corrosion, thiab mechanical puas. Txawm li cas los xij, los ntawm kev siv txoj hauv kev zoo rau kev saib xyuas thiab siv cov tswv yim zoo, lub neej ntawm koj lub twj tso kua mis impeller tuaj yeem txuas ntxiv.
Ib qho ntawm cov laj thawj tseem ceeb ntawm impeller tsis ua haujlwm yog cavitation, uas tshwm sim thaum lub siab ntawm cov kua dej poob qis dua nws qhov vapor siab, ua rau npuas tsim thiab tom qab ntawd implode. Qhov no tuaj yeem ua rau pitting, yaig, thiab tawg ntawm impeller nto. Txhawm rau tiv thaiv cavitation, xyuas kom meej tias lub twj tso kua mis yog qhov loj thiab qhov nqus siab tsis dhau qis. Tsis tas li ntawd, koj tuaj yeem nruab ib lub cavitation txo cov cuab yeej xws li diffuser lossis inducer.
Kev yaig yog lwm qhov ua rau impeller tsis ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj cov kua dej abrasive lossis cov dej ntws siab. Txhawm rau txo qhov kev pheej hmoo ntawm kev yaig, xaiv cov khoom siv impeller uas tiv taus hnav thiab tsim kua muag, xws li cov hlau tsis muaj zog, ceramic, lossis roj hmab. Nws tseem yog ib qho tseem ceeb kom tswj tau tus nqi ntws zoo ib yam thiab khaws cov kev tshem tawm ntawm lub impeller thiab vaj tse nyob rau hauv ib qho kev teev tseg.
Corrosion yog qhov thib peb uas tuaj yeem ua rau impeller tsis ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj cov kua dej corrosive heev. Txhawm rau txo qhov kev pheej hmoo ntawm corrosion, xaiv cov khoom siv twj tso kua mis uas tiv taus cov tshuaj tshwj xeeb raug thauj. Tsis tas li ntawd, siv cov coatings lossis liners uas impervious rau cov kua los tiv thaiv corrosion los ntawm kev cuam tshuam rau impeller nto.
Thaum kawg, txhua yam kev puas tsuaj tuaj yeem tshwm sim vim muaj ntau yam, suav nrog kev tuav tsis raug, kev sib raug zoo, thiab kev sib dhos tsis raug. Txhawm rau tiv thaiv cov teeb meem no, xyuas kom meej tias lub twj tso kua mis raug teeb tsa kom raug thiab tag nrho cov khoom sib xyaw kom raug thiab nruj. Tsis tas li ntawd, siv lub sijhawm saib xyuas tsis tu ncua los tshuaj xyuas lub twj tso kua mis, lub impeller, thiab lwm yam khoom siv rau cov cim ntawm kev hnav thiab kev puas tsuaj.
Hauv cov ntsiab lus, lub twj tso kua mis impeller tsis ua haujlwm tuaj yeem tshwm sim los ntawm ntau yam, tab sis muaj ntau lub tswv yim kev saib xyuas uas tuaj yeem siv los txuas ntxiv lub neej ntawm cov khoom tseem ceeb no. Los ntawm kev xaiv cov khoom siv impeller kom raug, tswj xyuas tus nqi zoo ib yam, thiab ua raws li lub sijhawm ua haujlwm tsis tu ncua, koj tuaj yeem tiv thaiv cavitation, yaig, corrosion, thiab mechanical puas tsuaj thiab xyuas kom meej tias koj lub twj tso kua mis ua haujlwm ntawm qhov siab tshaj plaws rau xyoo tom ntej.
