Lub impeller yog hais txog lub log disc nrog cov hniav txav. Hauv lub twj tso kua mis centrifugal, lub impeller yog hais txog lub cev tig nrog cov hniav uas hloov lub zog rau cov kua.
Cov hniav ntawm centrifugal twj impellers feem ntau yog rov qab nkhaus hniav. Muaj ob hom hniav: cylindrical thiab twisted. Kev siv cov twisted hniav tuaj yeem txo qhov load ntawm cov hniav, txhim kho kev ua haujlwm ntawm lub tshuab nqus tsev twj centrifugal, thiab txhim kho lub peev xwm los tiv thaiv cavitation, tab sis kev tsim khoom yog qhov nyuaj thiab tus nqi siab.
Lub centrifugal twj tso kua mis rau refining thiab tshuaj kev lag luam yuav tsum tau lub impeller yuav tsum tau cam khwb cia los yog tag nrho welded ib tug impeller. Kev loj hlob ntawm welded impellers feem ntau yog siv rau cov tshuaj tshwj xeeb centrifugal twj ua los ntawm cov ntaub ntawv hlau nrog cov khoom tsis zoo (xws li hlau thiab nws cov alloys). Lub geometric raug thiab nto tiav ntawm cov welded impeller yog zoo dua li cov cam khwb cia impeller, uas yog zoo los txhim kho lub efficiency ntawm lub centrifugal twj tso kua mis.
Raws li txoj kev ua, lub impeller tuaj yeem muab faib ua hom riveted, welded hom thiab ib hom. Lub impeller tsim ua ke feem ntau yog hais txog cov txheej txheem casting precision thiab lwm yam txheej txheem tshwj xeeb. Covprecision casting txheej txheemtxuag ob tus txiv neej-teev thiab cov ntaub ntawv, tab sis vim yog cov duab ntawm lub impeller thiab cov kev ua haujlwm siab, nws yog qhov nyuaj los xyuas kom meej tias cov castings tsis muaj pores thiab impurities.
RMC Foundrytuaj yeem tsim ntau hom impellers siv cov txheej txheem casting precision (kev nqis peev casting) thiabCNC precision machining. Peb tuaj yeem tsim cov high-precision, corrosion-resistant impellers los ntawm austenitic stainless hlau, duplex stainless hlau, nag lossis daus hardened stainless hlau, thiab nickel-based alloys.
Tam sim no, cov yam ntxwv ntawm cov twj tso kua mis centrifugal impellers yog hom ntws channel (ib leeg ntws channel, ob chav ntws channel), hom vane (kaw hom, qhib hom), kauv centrifugal hom thiab hom swirl.
1. Channel Hom Impeller
Flow channel impeller yog ib qho nkhaus ntws channel los ntawm inlet mus rau qhov hluav taws xob. Hom impeller no yog tsim rau kev xa cov kua uas muaj cov khoom loj ntawm impurities lossis ntev fibers. Vim tias hom impeller no muaj kev tiv thaiv zoo heev. Tab sis nws qhov tsis zoo yog qhov kev ua haujlwm tiv thaiv cavitation tsis muaj zog dua li lwm cov ntaub ntawv.
2. Vane Impeller
Lub semi-qhib thiab qhib impellers nyob rau hauv lub vane impeller yog yooj yim rau cam khwb cia, thiab yooj yim los tswj thiab ntxuav cov impurities thaiv nyob rau hauv cov txheej txheem conveying. Txawm li cas los xij, nws qhov tsis zoo yog qhov sib txawv ntawm cov phab ntsa sab hauv ntawm cov dej siab thiab cov hniav nyob rau hauv kev puas tsuaj ntawm cov khoom ua kom nce thaum lub sij hawm kev thauj mus los, uas txo cov kev ua haujlwm ntawm lub twj tso kua mis, thiab kev ruaj ntseg ntawm cov kua hauv lub xeev. nyob rau hauv lub ntws channel raug puas tsuaj vim qhov nce ntawm qhov sib txawv. , ua rau lub twj tso kua mis vibrate, hom impeller no tsis yooj yim rau kev thauj nruab nrab uas muaj cov khoom loj thiab cov fibers ntev. Lub kaw impeller muaj kev ua haujlwm siab thiab tuaj yeem ua haujlwm zoo rau lub sijhawm ntev. Lub axial thrust ntawm lub twj tso kua mis yog me me, tab sis lub impeller kaw yog ib qho yooj yim rau lub qhov txhab, thiab nws tsis yooj yim rau kev thauj cov dej phwj tawm uas muaj cov khoom loj lossis cov fibers ntev.
3. Kauv Centrifugal Impeller
Kauv centrifugal impellers muaj twisted hniav uas txuas axially los ntawm qhov chaw nres nkoj suction ntawm lub cev tapered hub. Cov kua xa tawm yuav tsis cuam tshuam ib feem ntawm lub twj tso kua mis thaum nws ntws los ntawm cov hniav, yog li tsis muaj kev puas tsuaj rau lub twj tso kua mis, thiab tib lub sijhawm, nws tsis muaj kev puas tsuaj rau cov kua xa tawm. Vim lub propulsion ntawm cov ntsia hlau, cov khoom ncua kev kawm ntawv muaj ib tug muaj zog passability, yog li no hom yog saws. Impeller twj tso kua mis yog tsim rau cov twj tso kua mis uas muaj cov khoom loj thiab cov fibers ntev.
4. Swirl Impeller
Lub impeller swirling yog tag nrho los yog ib feem ntawm lub impeller uas yog retracted mus rau lub ntws channel ntawm lub pressurized dej chamber, uas muaj zoo anti-clogging kev kawm. Cov khoom ntws nyob rau hauv cov dej siab chamber nyob rau hauv lub impetus ntawm lub vortex generated los ntawm kev sib hloov ntawm lub impeller, thiab lub zog ntawm tshem tawm hais tsis tsim lub zog, thiab exchanges zog nrog cov kua nyob rau hauv lub ntws channel. Thaum lub sij hawm cov txheej txheem ntws, cov khoom tshem tawm los yog cov fibers ntev tsis tiv nrog cov hniav hnav, cov hniav hnav ntau dua, thiab qhov sib txawv tsis loj vim yog kev puas tsuaj. Nws yog qhov tsim nyog rau kev siv cov xov xwm uas muaj cov khoom loj thiab cov fibers ntev.
Lub vane impellers siv hauv cov twj centrifugal tuaj yeem muab faib ua plaub hom: (a) kaw hom; (b) pem hauv ntej ib nrab qhib hom; (c) rear ib nrab qhib hom; (d) qhib hom
1. Kaw impeller
Lub kaw impeller muaj cov hniav thiab pem hauv ntej thiab nram qab daim hlau. Lub kaw impeller muaj kev ua haujlwm siab thiab nyuaj rau kev tsim khoom, thiab feem ntau yog siv hauv cov twj centrifugal. Nws yog qhov tsim nyog rau kev xa cov kua dej huv uas tsis muaj viscosity thiab tsis muaj cov khoom, xws li cov dej huv thiab cov kev daws teeb meem.
2. Ib nrab qhib impeller
Lub semi-open impeller feem ntau muaj ob lub qauv: ib qho yog pem hauv ntej semi-qhib hom, uas yog tsim los ntawm lub hau npog phaj thiab cov hniav. Lub impeller efficiency ntawm cov qauv no yog tsawg, thiab ib tug sealing nplhaib nrog adjustable clearance yog yuav tsum tau los txhim kho cov efficiency; Lwm qhov yog lub hau npog phaj thiab cov hniav. Lub semi-qhib hom muaj ib lub hau npog pem hauv ntej phaj thiab ib tug hniav. Txij li thaum tib lub nplhaib sealing raws li lub kaw impeller tuaj yeem siv tau, qhov ua tau zoo yog qhov zoo ib yam li cov impeller kaw, thiab cov hniav kuj tseem muaj (rov qab hniav lossis pab impeller) foob ntxiv rau kev xa cov kua. nyhuv. Lub semi-qhib impeller yog tsim rau kev xa cov kua uas muaj cov khoom tshem tawm xws li cov khoom siv thiab cov fibers. Lub semi-open impeller tsis yooj yim rau kev tsim khoom, tus nqi qis, thiab muaj zog yoog raws.
3. Qhib impeller
Lub impeller qhib tsuas muaj cov hniav thiab cov hniav txhawb nqa tav, thiab tsis muaj impeller nrog rau pem hauv ntej thiab nram qab daim hlau. Lub impeller muaj kev ua haujlwm tsawg thiab siv tsawg dua, thiab feem ntau yog siv los thauj cov kua dej uas muaj viscosity siab thiab slurry kua.
