(1) Cov khoom tseem ceeb ntawm ib-theem centrifugal twj: twj tso kua mis
Muaj ob hom twj tso kua mis: axial split thiab radial split. Feem ntau ib-theem centrifugal twj tso kua mis muaj volute casing, thaum ntau theem centrifugal twj feem ntau muaj ib tug radial split casing uas yog annular los yog ncig. Feem ntau, cov kab noj hniav sab hauv ntawm lub plhaub plhaub twj tso kua mis yog tsim los ua ib qho kauv ntws channel los sau cov kua ntws tawm ntawm lub impeller thiab coj nws mus rau cov yeeb nkab diffusion mus rau lub twj tso kua mis. Lub twj tso kua mis muaj tag nrho cov kev ua haujlwm siab thiab thermal load ntawm cov kua.
(2) Cov khoom tseem ceeb ntawm ib-theem centrifugal twj tso kua mis: impeller
Lub impeller tsuas yog ua haujlwm xwb, thiab lub twj tso kua mis ua haujlwm ntawm cov kua los ntawm lub impeller. Muaj peb hom qauv ntawm impellers: kaw, qhib, thiab semi qhib. Lub impeller kaw muaj cov hniav, lub hau npog pem hauv ntej, thiab lub phaj npog tom qab. Lub semi-open impeller muaj cov hniav thiab lub hau npog phaj. Qhib impellers tsuas muaj cov hniav thiab tsis muaj pem hauv ntej lossis nram qab daim hlau. Kaw impellers muaj kev ua haujlwm siab dua, thaum qhib impellers muaj kev ua haujlwm qis dua
(3) Cov khoom tseem ceeb ntawm ib-theem centrifugal twj tso kua mis: sealing nplhaib
Lub luag haujlwm ntawm lub nplhaib sealing yog txhawm rau tiv thaiv sab hauv thiab sab nraud ntawm lub twj tso kua mis. Lub nplhaib sealing yog ua los ntawm cov khoom siv hnav-tiv taus thiab tau kos rau ntawm daim phiaj pem hauv ntej thiab nram qab ntawm lub impeller thiab lub twj tso kua mis. Nws tuaj yeem hloov tau tom qab hnav.
(4) Cov khoom tseem ceeb ntawm ib-theem centrifugal twj tso kua mis: ncej thiab bearings
Ib kawg ntawm lub twj tso kua mis ncej yog tsau nrog ib tug impeller, thiab lwm kawg yog nruab nrog ib tug coupling. Raws li qhov loj ntawm lub twj tso kua mis, dov bearings thiab zawv zawg bearings tuaj yeem xaiv tau raws li cov kabmob.
(5) Cov khoom tseem ceeb ntawm ib-theem centrifugal twj tso kua mis: ncej foob
Feem ntau muaj ob hom ntawm cov ntsaws ruaj ruaj: mechanical seals thiab packing seals. Feem ntau, cov twj tso kua mis yog tsim los ua kom haum rau ob qho tib si ntim cov ntsaws ruaj ruaj thiab cov tshuab foob.
