Nws txhais li cas rau lub ceramic impeller kom ua tiav qhov ntsuas qhov tseeb ntawm Qib G2.5?
Thaum koj pom "ceramic impeller dynamically balanced rau G2.5" nyob rau hauv lub twj tso kua mis spec, nws txhais tau hais tias lub impeller qhov nruab nrab ntawm pawg tau khaws cia nyob rau hauv ib tug nruj heev offset los ntawm nws axis ntawm kev sib hloov. Tsis muaj impeller los ntawm sintering thiab tiav kev sib tsoo nrog zoo kawg nkaus txawm cov khoom faib. Ib txwm muaj qhov sib txawv me me ntawm qhov nruab nrab ntawm qhov loj thiab qhov chaw hloov pauv. Thaum ceev, qhov sib txawv ntawd hloov mus rau hauv lub zog centrifugal rov ua dua. Lub impeller nrawm dua, qhov muaj zog uas lub zog tau txais. Dynamic balancing yog hais txog tuav qhov offset nyob rau hauv ib tug tswj kev txwv.
G2.5 los ntawm ISO 1940. Tus lej tom qab G yog qib zoo sib npaug, qhia hauv mm/s. Nws sawv cev rau qhov tso cai tshaj tawm ntawm lub rotor qhov nruab nrab ntawm huab hwm coj. G2.5 txhais tau tias 2.5 mm / s. Ib tug me me txhais tau hais tias ib tug me me tso cai eccentricity. Ntawm 3000 rpm, G2.5 ua haujlwm rau kwv yees li 8 microns ntawm kev tso cai eccentricity - tsawg dua ib - kaum ntawm cov plaub hau tuab ntawm tib neeg. Yog tias qhov ceev qis dua, qhov tso cai eccentricity loj dua. Yog hais tias qhov ceev yog siab dua, qhov tso cai eccentricity tau txais txawm me me.
Rau lub impeller ceramic, tus lej muaj lub ntsiab lus tshwj xeeb. Qhov tso cai seem tsis sib npaug sib npaug ntawm qhov tso cai eccentricity muab faib los ntawm impeller loj. Ceramic feem ntau yog tuab dua li cov hlau tsis muaj steel, yog li lub impeller ceramic ntawm tib qhov ntev hnyav dua. Qhov ntawd txhais tau hais tias ntawm G2.5, qhov kev tso cai tsis sib npaug tseem tsawg dua. Siv 0.5 kg ceramic impeller khiav ntawm 3000 rpm. Qhov tso cai seem tsis sib npaug tuaj txog li 4 g·mm.
Kho qhov nyiaj tshuav rau qib ntawd txhais tau hais tias ntxiv lossis tshem tawm cov khoom hauv milligram nyiaj. Ceramic yog ib qho nyuaj thiab nkig, yog li koj tsis tuaj yeem welding ntawm qhov hnyav los yog nias hauv qhov sib npaug slugs txoj kev koj tuaj yeem nrog lub impeller hlau. Nws feem ntau yuav tsum tau ua los ntawm kev sib tsoo precision, tshem tawm cov khoom me me. Ntaus G2.5 tsis tu ncua qhia koj txog qhov zoo ntawm sintered dawb paug, fixturing, thiab kev sib tsoo tswj yog tag nrho nyob rau hauv ib tug ruaj khov ntau yam.
G2.5 tsis txhais hais tias xoom vibration. Nws txhais tau hais tias lub zog hloov pauv los ntawm kev tsis sib npaug yog khaws cia qis. Centrifugal force scales nrog eccentricity, loj, thiab square ntawm ceev. Yim microns suab me me, tab sis ntawm ob peb txhiab rpm uas me me eccentricity ua rau rov ua haujlwm ntawm cov kabmob thiab cov tshuab foob ntawm tib zaus. Piv nrog G6.3, uas yog ib txwm muaj rau lub twj tso kua mis rotors, G2.5 tso cai tsuas yog li 40% ntawm cov eccentricity ntawm tib ceev, yog li lub zog tsis sib npaug poob los ntawm kwv yees li qhov sib npaug. Rau cov neeg siv lub twj tso kua mis, qhov sib txawv ntawm qhov sib txawv feem ntau tshwm sim raws li lub suab nrov qis, cov kabmob txias, thiab lub neej ntev dua ntawm lub tshuab foob - tshwj xeeb tshaj yog nyob rau hauv tas li- daim ntawv thov kev ua haujlwm, kev teeb tsa nrog cov kav dej tsis zoo, lossis txhua qhov kev vibration yog ib qho kev txhawj xeeb.
Ceramic impeller cim G2.5 tsis yog hais txog qhov ntsuas lub tshuab nyeem ib zaug xwb. Density distribution after sintering, wall thickness variation, and how the part is located during finish machining all affect the final balance. Ntaus G2.5 ntawm ib daim yog txawv los ntawm tuav nws hla ntau lawm. Cov tom kawg hais ntxiv txog kev tswj cov txheej txheem. Nyob rau hauv tas li ntawd, qhov parameter no yog lub hom phiaj tseem ceeb siv rau machining raug thiab sib xws.
Nyob rau hauv luv luv, ib tug ceramic impeller sib npaug rau G2.5 tau dhau los ntawm qhov siab ncaj - qib dynamic ntsuas txheej txheem ua ntej tawm hauv lub Hoobkas. Nyob ze nws qhov ntsuas ceev, qhov kev sib hloov eccentricity tshwm sim los ntawm qhov tsis sib xws loj faib tau tuav mus rau ob peb microns. Nws tsis yog kev cog lus ntawm xoom kev vibration, tab sis nws txhais tau hais tias lub impeller nws tus kheej yog tsim kom tau raws li qhov qis - kev vibration, qis- suab nrov, thiab ntev bearing lub neej xav tau ntawm lub twj tso kua mis. Zuag qhia tag nrho cov twj tso kua mis kev ua tau zoo tseem nyob ntawm lub cev muaj zog, ncej sib dhos, lub twj tso kua mis, thiab lwm yam. G2.5 yog qhov muaj txiaj ntsig zoo tshwj xeeb thaum txiav txim siab impeller ua haujlwm thaum xaiv, tab sis nws yuav tsum tsis txhob raug coj los ua ib qho kev ntsuas ntawm kev ua tiav twj tso kua mis.
