Tus txheej txheem ua hauj lwm ntawm centrifugal twj tso kua mis yog kom nqus tau nruab nrab los ntawm centrifugal quab yuam los ntawm kev sib hloov siab ntawm tus impeller.
Ua ntej lub twj tso kua dej pib ua haujlwm, lub twj tso kua mis lub cev thiab cov hluav taws xob hauv cov yeeb nkab yuav tsum muaj dej nrog tiv thaiv cavitation. Thaum lub impeller rolls sai sai, cov hniav ua rau dej tig sai sai, thiab cov dej tig mus deb ntawm qhov kev ua ntawm Centrifugal quab yuam. Tom qab cov dej hauv lub twj tso kua mis tau pov tseg, lub tshuab nqus tsev yog tsim nyob rau hauv lub hauv paus feem ntawm tus impeller. Dej yog nias rau hauv cov roj hauv cov yeeb nkab hauv cov raj xa hluav taws xob hauv qab kev txiav txim ntawm kev ua siab siab (lossis siab tso dej). Lub voj voog no tuaj yeem ua tiav kev nqus tas.
Nws yog tsim nyog teev uas ua ntej pib lub twj tso kua mis centrifugal, txwv tsis pub nws yuav ua rau lub twj tso zis dej, thiab ua kom lub twj tso dej tawm (raug xa mus rau "cavitation" ), uas ua rau cov khoom siv hluav taws xob!
Qhov thiaj li hu cavitation yog hais txog qhov tshwm sim uas thaum lub taub dej centrifugal tau pib, yog tias muaj huab cua qis ntawm huab cua, lub zog centrifugal tsim tawm tom qab sib hloov yog qhov me me. Yog li ntawd, qhov kev siab tsis tshua muaj tsim nyob rau hauv nruab nrab cheeb tsam ntawm impeller tsis txaus los nqus cov kua hauv qab lub twj tso kua mis, thiab cov kua dej tsis tuaj yeem thauj.
Kev ua tau zoo ntawm lub twj tso kua mis centrifugal yog cov khoom ntawm cov neeg kho tshuab, volumetric, thiab hydraulic efficiies. Kev ua haujlwm ntawm cov chav nqus dej yog cov khoom ntawm cov twj tso kua mis ua tau thiab lub cev muaj zog. Cov ntsiab lus tseem ceeb ua rau muaj kev ua haujlwm tsawg ntawm centrifugal nqus chav nyob yog raws li hauv qab no.
Kev ua haujlwm ntawm lub twj tso kua mis nws tus kheej yog qhov cuam tshuam tseem ceeb tshaj plaws. Raws li cov kev ua haujlwm qub, kev ua haujlwm ntawm cov twj yuav txawv ntawm ntau dua 15%.
2. Qhov kev ua haujlwm ntawm cov twj tso kua mis Centrifugal yog qis dua lawv cov kev mob siab, ua rau muaj kev ua haujlwm tsawg thiab kev siv hluav taws xob tsawg.
3. Kev ua haujlwm ntawm lub cev muaj zog tseem tsis hloov pauv thaum lub sijhawm ua haujlwm. Yog li ntawd, xaiv lub cev muaj zog loj yog qhov tseem ceeb heev.
Qhov cuam tshuam ntawm kev siv tshuab hluav taws xob yog feem ntau cuam tshuam rau kev tsim qauv thiab tsim khoom zoo. Tom qab lub twj tso kua mis tau xaiv, qhov cuam tshuam ntawm kev kho mob tom qab yog me me.
5. Hydraulic poob suav nrog kev txhuam khaub ncaws kub thiab tsis muaj zog. After running for a certain period of time, centrifugal pumps inevitably cause surface wear on components such as impellers and guide vanes, increase hydraulic losses, and decrease hydraulic efficiency.
6. Cov ntim poob ntawm cov twj tso kua mis centrifugal, kuj hu ua toastter seales rings, imperstage part, thiab axial corancing kev ua haujlwm. Qib ntawm Volumetric efficiency yog tsis tsuas muaj feem cuam tshuam txog kev tsim qauv thiab tsim khoom, tab sis kuj rau kev tswj hwm tom qab. Tom qab khiav tsis tu ncua rau qee lub sijhawm, vim kev sib txhuam ntawm ntau yam, qhov kev tshem tawm nce thiab volumetric efficiency txo.
7. Centrifugal nqus dej nqus plua plav thiab tsis xav tau vim muaj kev thaiv ntawm lub tog raj kheej ntawm lub tog raj kheej, xa hluav taws xob, thiab lwm yam laj thawj.
8. Ua ntej pib lub twj tso kua mis, cov neeg ua haujlwm tsis xyuam xim rau txoj haujlwm npaj ua ntej pib cov twj tso kua mis. Cov txheej txheem kev ua haujlwm yooj yim xws li ua kom sov sov, rhuav tshem cov twj tso kua mis, uas feem ntau ua rau cov cav tov, uas feem ntau ua rau lub cev muaj zog, kev co, thiab cov kua muag tsis tau zoo.
