Centrifugal twj tso kua mis kaw feem ntau yog los ntawm qhov tsis ua tiav ntawm lub tshuab foob. Ua tsis tiav ntawm kev ua haujlwm ntawm feem ntau ntawm cov paim quav, vim li cas rau hauv qab no:
Ring qhov zoo li qub thiab lub zog sib nqus lub nplhaib sab saum npoo dej, qhov laj thawj tseem ceeb yog: qhov kawg ntawm lub dav hlau tiaj tiaj, kev ntxhib ntxoo tsis tau raws li qhov yuav tsum tau ua, lossis nplaim qhov saum npoo; nruab nrab ntawm qhov kawg ntawm cov teeb meem me me, uas ua rau ob qhov xaus tsis tuaj yeem khiav tib yam; installation tsis nyob hauv qhov chaw, txoj kev tsis yog qhov tseeb.
② cov nyiaj them rau lub nplhaib foob ntsaws ruaj ruaj, qhov laj thawj tseem ceeb yog: cov qog deformation, preload tsis sib thooj; installation tsis yog qhov tseeb; foob ​​tsis zoo tsis cuag tus qauv; kev xaiv foob tsis yog lawm.
Kev siv qhov tseeb ntawm qhov txiaj ntsig pom tau hais tias qhov ua tsis tau zoo tshaj plaws ntawm qhov chaw sib khi tau txav mus thiab lub nplhaib zoo li qub ntawm qhov kawg, centrifugal twj sealing, lub nplhaib zoo li qub kawg ntawm qhov tawg yog qhov tshwm sim tsis sib xws, qhov laj thawj tseem ceeb yog: ① installation sealing nto qhov sib txawv loj dhau, Cov kua dej ua kom dhau mus coj los siv thaum tshav kub uas ua kom muaj los ntawm kev sib txhuam; qhov dej ntws tawm ntawm lub ntsej muag sib cais, ua rau lub ntsej muag kawg kom kub thiab puas.
② kua media vaporization expansion, yog li ob qho tib si xaus los ntawm kev vaporization ntawm nthuav tawm quab yuam thiab sib cais, thaum ob lub nplaim sealing yuam, ua kom puas zaj duab xis lubricating thiab yog li ua rau cov nplaim dej dhau los ua kom kub.
③ tsis zoo ua kua tawm lubrication, txuas nrog lub siab khiav hauj lwm siab dhau, ob qhov chaw kaw qhov chaw mus los tsis hloov. Piv txwv li, qhov chaw siab ntawm lub twj tso kua mis tawm ceev yog 20445r / min, qhov chaw sealing qhov nruab nrab yog 7cm, lub twj tso kua mis nrawm tom qab cov kab nrawm nce mus txog 75m / s, thaum muaj qhov sealing qhov chaw lag luam tsis tuaj yeem taug qab kev sib hloov, qhov kub ceev tam sim los ntawm sealing sab saum toj puas.
