Hollow ncej separators yog electrostatic separators siv los cais cov ntaub ntawv uas tuaj yeem raug them los ntawm kev sib txhuam. Lawv feem ntau yog siv rau hauv cov txheej txheem tsim khoom uas muaj cov pob zeb sib tsoo cov ntaub ntawv raw, pulverized thee, thiab cement. Cov khoom siv no txhawb nqa lub tshuab lub cev ua haujlwm ntawm lub hollow ncej thiab kawg npog. Tom qab siv sijhawm ntev, cov kab nrib pleb ua rau muaj qhov tshwm sim ntawm qhov pub thiab tso tawm, yuav tsum tau hloov pauv ntawm - qhov chaw.
Nyob ntawm hom kev sib txuas, muaj peb hom qauv: bolted kev twb kev txuas, welded, thiab ib qho casting. Cov txheej txheem hloov pauv yuav suav nrog kev tshem tawm cov kabmob vaj tsev, welding tus ntoo khaub lig bracket kom tsis txhob deformation, thiab haum cov kabmob kheej kheej. Ib qho piv txwv yog Φ2.4m × 12m ntug-tsav cement zeb qhov twg, tom qab hloov, lub radial runout tsawg dua 0.5mm, thiab cov kabmob kub yog tswj ntawm 46℃thiab 52℃. Rau Φ4m × 13m cement zeb, radial runout kam rau ua yog tswj nyob rau hauv ± 0.30mm, thiab tshav kub rwb thaiv tsev lub tes tsho thiab cua txias ducts yog siv los txo cov bearing kub. Thaum lub sij hawm installation, nws yog ib qho tseem ceeb kom paub meej tias lub hollow ncej concentricity, radial runout tus nqi, thiab axial runout ntawm kheej kheej bearing raws li specifications.
