Slurry impeller kev xav tau

Slurry impeller kev xav tau

Txheeb xyuas lub ntsej muag kawg ntawm lub ntsej muag A ntawm lub hom phiaj ntawm phau ntawv xov xwm yog los tiv thaiv kev sib sau ntawm qhov yuam kev, thaum haum rau me me ntaus ntau dhau, cuam tshuam rau cov khoom zoo.Kev ntsuas lwm lub ntsej muag mus rau lub ntsej muag sib luag rau lub dav hlau siv, tab sis tsis yog sab nraud ntsib cov ntawv xov xwm ntawm lub ntsej muag ntsuas lub ntsej muag, yog vim li cas qee zaum yuav tsum tau siv rau txoj kev ntsuas, qee zaum txhawm rau kom muaj kev cuam tshuam zoo rau kev ua haujlwm zoo.

Runout thiab parallelism tsis pom zoo nyob rau hauv Table 10-8 sib txawv ntawm cov duab thiab txoj hauj lwm, qib precision xaiv.Keyway centerline axis kab rau skew yog hais txog qhov nruab nrab ntawm txoj kev tseem ceeb ntawm lub kaum sab xis mus rau lub ncej axis.Skew dhau impeller tsis loaded, tshwj xeeb tshaj yog multi-theem twj tso kua mis sib dhos nyuaj dua.

Yog li ntawd, yuav tsum nruj dua rau skew, feem ntau 100 mm ntev keyway skew kam rau ua 0.03 hli.Keyway offset yog txav mus rau qhov sib npaug nrog cov kab axis.Tsawg cuam tshuam rau lub rooj sib txoos, kev kam rau siab yog qhov loj, qhov dav dav ntawm 0.06 hli zawj offset.Nyob rau hauv thiaj li yuav khaws lub center qhov yog ib lub qhov nyob rau hauv thiaj li yuav overhaul lub hauv paus ntawm lub centering.Kev kuaj ultrasonic ntawm cov ncej thiab lub hom phiaj sib nqus yog los xyuas seb puas muaj qhov tsis xws luag hauv cov ncej, lub ncej kom ntseeg tau tias kev ua haujlwm.Centrifugal twj tso kua mis impeller yog qhov tseem ceeb.

Kev ua tau zoo thiab impeller centrifugal twj tsim thiab kev tsim khoom (casting thiab machining) yog ze rau qhov zoo.Impeller tsim cov duab kos thiab cov kev xav tau qhia hauv daim duab 10-2,slurry twj manufacturersCov kev cai ntawm lub impeller thawj, thib ob, peb lub peev xwm kev cai thiab cov ncej zoo sib xws, saib cov ncej ncej.

Runout tolerances pom zoo nyob rau hauv Table 10-7 zoo thiab txoj hauj lwm sib txawv VII qib precision xaiv, lub ntsej muag runout tolerances pom zoo nyob rau hauv Table 10-8 Tshooj VI VII geometric deviation theem precision xaiv.Txawm hais tias cov duab sib npaug ntawm lub impeller, tab sis nyob rau hauv tus txheej txheem ntawm casting thiab machining yuam kev yeej ib txwm muaj, uas yog ib qho ntawm cov laj thawj centrifugal vibration tshwm sim.Yog li koj yuav tsum tau statically balanced impeller tiav kom tshem tawm qhov hnyav tsis sib npaug.

General centrifugal twj tso kua mis impeller static tshuav nyiaj li cas tolerances pom zoo nyob rau hauv Table 10-9 xaiv.Impeller static balance test, pem hauv ntej npog nrog txoj kev txiav kom tshem tawm qhov tsis sib xws, txiav phaj thickness yuav tsum tsis pub tshaj 1/3.Los ntawm sab xub ntiag, lub vaj huam sib luag tom qab txiav tawm cov hlau ntau dhau, tab sis qhov txiav yuav tsum tau txuas nrog lub disc du.Impeller thib tsib kev cai yuav tsum tau, feem ntau yooj yim overlooked.Hauv kev xyaum ntau lawm vim cov xuab zeb tsuas yog gill tsis tiav, tab sis qhov cuam tshuam rau cov khoom ua tau zoo yog qhov tshwm sim, tab sis kuj yog los ntawm kev ntsuas kev ua haujlwm feem ntau yog kev kho, siv sijhawm ntau, yog li lub impeller yuav tsum ua tib zoo xuab zeb tsuas yog gill.
