1. Impeller qauv hom: Lub impeller qauv muab faib ua plaub pawg: hom hniav (qhib, kaw), swirl hom, channel hom, (xws li ib channel thiab ob chav channel) kauv hom centrifugal. Qhov qhib semi qhib impeller yog ib qho yooj yim rau kev tsim khoom thiab tuaj yeem ntxuav tau yooj yim thiab kho thaum muaj kev cuam tshuam hauv lub impeller. Txawm li cas los xij, nyob rau hauv kev ua haujlwm ntev, kev tshem tawm ntawm cov hniav thiab sab phab ntsa ntawm cov chav dej siab yuav nce ntxiv vim qhov ua kom puas, ua rau txo qis kev ua haujlwm. Thiab nce qhov sib txawv yuav cuam tshuam lub siab faib ntawm cov hniav. Tsis tsuas yog nws tsim kom muaj qhov loj ntawm vortex poob, tab sis nws kuj ua rau kom lub zog axial ntawm lub twj tso kua mis. Nyob rau tib lub sijhawm, vim qhov sib txawv ntau ntxiv, kev ruaj ntseg ntawm cov kua dej hauv cov channel raug cuam tshuam, ua rau lub twj tso kua mis vibrate. Hom impeller no tsis yooj yim rau kev thauj cov xov xwm uas muaj cov khoom loj thiab cov fibers ntev. Hais txog kev ua tau zoo, hom impeller no muaj kev ua haujlwm tsawg, nrog rau qhov ua tau zoo tshaj plaws ntawm li 92% ntawm qhov zoo tib yam kaw impellers, thiab lub taub hau ncaj ncaj.
2. Swirl impeller: Cov twj siv hom impeller no muaj qee qhov los yog tag nrho cov impeller retracted los ntawm lub siab chamber flow channel. Yog li nws muaj qhov ua tau zoo tsis thaiv kev ua haujlwm, muaj zog particle dhau lub peev xwm thiab ntev fiber ntau dhau lub peev xwm. Cov khoom ntws nyob rau hauv lub siab dej chamber thiab yog propelled los ntawm lub vortex generated los ntawm kev sib hloov ntawm lub impeller. Cov khoom raug tshem tawm lawv tus kheej tsis tsim lub zog, tab sis tsuas yog pauv lub zog nrog cov kua hauv cov dej ntws. Thaum cov txheej txheem ntws, cov khoom raug tshem tawm lossis cov fibers ntev tsis tuaj yeem sib cuag nrog cov hniav, thiab qhov xwm txheej ntawm cov hniav hnav yog me ntsis. Tsis muaj kev nce ntxiv hauv kev tshem tawm vim kev puas tsuaj, thiab nws yuav tsis ua rau muaj kev poob qis thaum lub sijhawm ua haujlwm ntev. Lub twj tso kua mis siv hom impeller no yog tsim rau kev siv cov xov xwm uas muaj cov khoom loj thiab cov fibers ntev. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, qhov ua tau zoo ntawm lub impeller no kuj tsawg, tsuas yog li ntawm 70% ntawm qhov uas tsis tu ncua kaw impeller, thiab lub taub hau nkhaus yog tiaj tus.
3. Kaw impeller: Hom impeller no muaj kev ua haujlwm zoo dua qub. Thiab nyob rau hauv kev ua haujlwm ntev, qhov xwm txheej yog qhov ruaj khov. Cov twj tso kua mis siv hom impeller no muaj cov axial me me thiab tuaj yeem nruab nrog cov cuab yeej pab rau ntawm daim phiaj pem hauv ntej thiab nram qab. Cov cuab yeej pabcuam ntawm lub phaj npog pem hauv ntej tuaj yeem txo qhov vortex poob ntawm lub impeller inlet thiab hnav cov khoom ntawm lub nplhaib sealing. Cov hniav thib ob ntawm lub phaj npog tom qab tsis yog tsuas yog ua haujlwm kom sib npaug axial rog, tab sis kuj tiv thaiv cov khoom raug tshem tawm los ntawm kev nkag mus rau hauv lub tshuab foob chamber thiab muab kev tiv thaiv rau lub tshuab foob. Txawm li cas los xij, hom impeller no muaj kev ua haujlwm tsis zoo, tsis yooj yim rau qhwv, thiab tsis haum rau kev siv cov dej phwj tuaj uas tsis muaj cov khoom siv loj (ntev fibers).
4. Flow channel impeller: Hom impeller no belongs rau bladeless impellers, thiab impeller flow channel yog nkhaus ntws channel los ntawm inlet mus rau qhov hluav taws xob. Yog li nws yog qhov tsim nyog rau kev siv cov xov xwm uas muaj cov khoom loj thiab cov fibers ntev. Zoo tiv thaiv thaiv kev ua haujlwm. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, hom impeller no muaj kev ua haujlwm siab thiab tsis txawv ntawm cov impellers zoo tib yam, tab sis lub taub hau nkhaus ntawm lub twj tso kua mis nrog hom impeller poob qis heev. Lub zog nkhaus yog qhov ruaj khov thiab tsis ua rau muaj teeb meem ntau dhau, tab sis qhov kev ua haujlwm cavitation ntawm hom impeller no tsis zoo li qhov zoo tib yam kaw impellers, tshwj xeeb tshaj yog tsim rau siv hauv cov twj tso kua mis nrog lub siab inlet.
5. Kauv centrifugal impeller: Cov hniav ntawm hom impeller no yog twisted kauv hniav uas txuas axially los ntawm qhov chaw nres nkoj nqus ntawm lub cev conical hub. Hom impeller twj tso kua mis no muaj ob qho tib si ua haujlwm ntawm lub twj tso kua mis zoo thiab lub twj tso kua mis centrifugal. Thaum tshem tawm cov khoom ntws los ntawm cov hniav, lawv tsis cuam tshuam ib feem ntawm lub twj tso kua mis, yog li nws muaj cov khoom tsis zoo. Tsawg kev puas tsuaj rau cov khoom siv. Vim cov nyhuv propulsion ntawm kauv, tshem tawm hais tias muaj zog passability, yog li cov twj siv hom impeller yog tsim rau siv cov xov xwm uas muaj cov khoom loj thiab cov fibers ntev, nrog rau cov xov xwm siab. Nws muaj cov yam ntxwv pom tseeb nyob rau hauv cov xwm txheej uas muaj cov kev cai nruj rau kev puas tsuaj ntawm cov khoom nruab nrab conveying.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lub twj tso kua mis muaj ib tug ntxhab taub hau nkhaus thiab ib tug kuj flat zog nkhaus.
Cov hom siab tshaj plaws uas siv hauv cov kav dej phwj yog cov volute, thiab radial qhia vanes lossis ntws channel qhia vanes feem ntau yog siv hauv cov twj submersible. Muaj peb hom snail shells: kauv, nplhaib, thiab nruab nrab. Kauv volutes yeej tsis siv hauv cov twj tso kua mis. Circular pressurized water chambers feem ntau yog siv hauv cov kav dej me me vim lawv cov qauv yooj yim thiab kev tsim khoom yooj yim. Txawm li cas los xij, vim qhov tshwm sim ntawm nruab nrab (semi kauv) lub siab chambers, daim ntawv thov ntau yam ntawm annular siab chambers tau maj mam ua me. Vim lub fact tias lub intermediate hom dej siab chamber muaj ob lub helical permeability thiab siab permeability ntawm lub annular dej siab chamber. Nws tau txais kev pom zoo los ntawm cov tuam ntxhab.
Hauv cov ntsiab lus, tsis hais txog ntawm cov kav dej phwj tuaj, nws tsuas yog sib xyaw ua ke ntawm ntau hom impellers thiab lub siab chamber raws li qhov yuav tsum tau ua ntawm cov khoom nruab nrab thiab kev teeb tsa, tsuav yog lub impellers thiab lub siab chamber tuaj yeem ua tiav qhov kev teeb tsa zoo. Qhov ntau yam kev ua tau zoo ntawm lub twj tso kua mis yuav lav.
