Lub impeller yog dab tsi?

Lub impeller yog ib lub rotor tsav uas siv los ua kom lub siab thiab ntws ntawm cov kua. Nws yog qhov opposite ntawm aturbine twj, uas rho tawm lub zog los ntawm, thiab txo qhov siab ntawm, ib qho dej ntws.

Kev hais lus nruj me ntsis, cov kiv cua yog cov chav kawm ntawm cov impellers qhov twg cov dej ntws nkag mus thiab tawm axially, tab sis nyob rau hauv ntau lub ntsiab lus lub ntsiab lus "impeller" yog tshwj tseg rau cov tsis-propellor rotors qhov twg cov dej nkag mus rau hauv axially thiab tawm radially, tshwj xeeb tshaj yog thaum tsim suction hauv. lub twj tso kua mis los yog compressor.

Dab tsi yog hom impeller?

1, Qhib impeller

2, Semi qhib impeller

3, kaw impeller

4, Ob chav suction impeller

5, Mixed flow impeller

Dab tsi yog qhov txhais ntawm ntau hom Impeller?

Qhib impeller

Lub impeller qhib tsis muaj dab tsi tab sis vanes. Vanes yog txuas rau hauv nruab nrab hub, tsis muaj daim ntawv los yog sidewall los yog shroud.

Semi-qhib impeller

Semi-qhib impellers tsuas yog muaj phab ntsa rov qab uas ntxiv dag zog rau lub impeller.

Kaw impeller

Kaw-impellers tseem hu ua 'enclosed impellers'. Hom impeller no muaj ob sab pem hauv ntej thiab nraub qaum; lub impeller vanes yog sandwiched ntawm ob lub shrouds.

Ob chav suction impeller

Ob chav suction impellers kos cov kua rau hauv lub impeller vanes los ntawm ob sab, ntsuas lub axial thrust lub impeller imposes ntawm lub twj tso kua mis ncej bearings.

Mixed flow impeller

Mixed flow impellers zoo ib yam li radial flow impellers tab sis raug cov kua dej mus rau qib ntawm radial flow txhawm rau txhim kho kev ua haujlwm.

Yuav xaiv lub impeller li cas?

Muaj ntau yam uas peb yuav tsum xav txog thaum peb xaiv lub impeller.

1, Muaj nuj nqi

Kawm paub meej tias koj yuav siv nws li cas thiab seb qhov hnav thiab tsim kua muag yuav ua li cas.

2, Flow

Tus qauv ntws qhia hom twj tso kua mis impeller koj yuav tsum tau txais.

3, Khoom siv

Cov xov xwm lossis cov kua dej twg yuav dhau los ntawm lub impeller? Nws puas muaj cov khib nyiab? Yuav ua li cas corrosive?

4, Nqis

Tus nqi pib yog siab dua rau lub impeller zoo. Txawm li cas los xij, nws muab koj cov nyiaj rov qab ntau dua ntawm kev nqis peev vim tias koj siv nyiaj tsawg dua rau kev saib xyuas. Nws kuj tseem txhawb nqa cov khoom tsim tau raws li nws siv sijhawm ua haujlwm ntau dua.
