Feem ntau, pib lubcentrifugal twj tso kua misRaws li qhov tshwj xeeb yuav tsum yog, thawj lub twj tso kua mis chamber ntim nrog nruab nrab, kaw lub qhov hluav taws xob valve, thiab tom qab ntawd qhib lubtwj, lub hom phiaj yog: ntawm ib sab los tiv thaiv qhov pib ntawm qhov tam sim no yog kev puas tsuaj loj heev rau lub cev muaj zog;Ntawm qhov tod tes, tiv thaiv kom tsis txhob poob siab tom qab pib lubtwj, ua rautwjcavitation.Tab sis muaj ntau yam teeb meem tsis tuaj yeem hais dav dav!
Rau qis ntws thiab qis taub hautwj, kaw lossis tsis kaw lub qhov hluav taws xob valve tsis yog qhov teeb meem.
Rau lojtwj, lub qhov hluav taws xob feem ntau qhib me ntsis kom tsis txhob muaj qhov sib txawv ntawm lub hauv ntej thiab sab nraub qaum ntawm lub valve tom qab pib, thiab lub qhov hluav taws xob qhov hluav taws xob tsis yooj yim qhib, yog li qhov qhib ntawm lub qhov hluav taws xob valve yog qhib me ntsis.
Ib txhiacentrifugal twj tso kua misyuav me ntsis qhib lub qhov hluav taws xob valve vim preheating thiab lwm yam kev xav tau.
Yog hais tias nws yog nrog suction, kom kaw tag nrho lub qhov hluav taws xob valve, thiab tom qab ntawd qhib lub valve (tsis yog tus kheej-priming twj), tab sis kuj qhib lub twj tso kua mis valve.
Rau qee qhov tshwj xeeb, lub qhov hluav taws xob tsis tuaj yeem qhib tau, piv txwv li, kua propylene, yog tias lub qhov hluav taws xob qhib ua ntej, propylene vaporizes, lub twj tso kua mis yuav tsis tuaj yeem siab, yog li nws yuav tsum tau kaw ua ntej, twj tso kua mis thiab ces sai sai qhib lub qhov hluav taws xob valve.
Cov saum toj no yog cov twj centrifugal.Rau lwm hom twj, qhov xwm txheej yog raws li nram no:
1. Loj txaus pib-up yam ntxwv ntawm axial txaus twj-tag nrho qhib valve pib-up
Lub zog ntawm lub axial ntwstwjyog qhov loj tshaj plaws ntawm xoom txaus, uas yog 140% ~ 200% ntawm lub zog ncej, thiab lub zog yog qhov tsawg tshaj plaws ntawm qhov siab tshaj plaws ntws.Yog li ntawd, txhawm rau txo qhov pib tam sim no, cov yam ntxwv pib ntawm lub zog ntawm lub zog yuav tsum yog qhov pib loj (piv txwv li, qhib lub valve pib ).
2. Pib-up yam ntxwv ntawm mix-flow twj-tag nrho qhib valve pib-up
Lub zog ntawm qhov sib xyaw ua ketwjntawm xoom flow condition yog nruab nrab ntawm ob saum toj notwj, uas yog 100% ~ 130% ntawm lub zog ntsuas.Yog li ntawd, cov yam ntxwv pib ntawm lub twj tso kua mis sib xyaw ua ke yuav tsum nyob nruab nrab ntawm ob qho saum toj notwj, thiab nws yog qhov zoo dua los pib nrog lub valve qhib tag nrho.
3. Pib-up yam ntxwv ntawm vortex twj tso kua mis-tag nrho qhib valve pib-up
Lub zog ntawm lub vortextwjyog qhov loj tshaj plaws ntawm xoom txaus, uas yog 130% ~ 190% ntawm lub zog ncej.Yog li ntawd, zoo ib yam li cov axial ntwstwj, cov yam ntxwv pib ntawm lub vortex twj tso kua mis yuav tsum loj txaus pib-up (uas yog, tag nrho valve start-up ).
