Vo v\u00fdrobe boli s na\u0161ou pomocou vyvinut\u00e9 a zaveden\u00e9 stojany na vyva\u017eovanie zmontovan\u00fdch rotorov vo vysokor\u00fdchlostn\u00fdch v\u00e1kuov\u00fdch \u010derpadl\u00e1ch. Tieto rotory musia sp\u013a\u0148a\u0165 pr\u00edsne po\u017eiadavky na kvalitu vyv\u00e1\u017eenia v s\u00falade s presnos\u0165ou triedy 1 pod\u013ea GOST 22061-76, sovietskej normy kvality vyv\u00e1\u017eenia (jej modern\u00fdm medzin\u00e1rodn\u00fdm ekvivalentom je ISO 21940-11, predt\u00fdm ISO 1940-1), ke\u010f\u017ee ich prev\u00e1dzkov\u00e1 frekvencia sa pohybuje od 42,000 do 60,000 RPM.<\/p>\n

  1. Prv\u00e1 f\u00e1za<\/strong>: V tejto f\u00e1ze, ke\u010f r\u00fdchlos\u0165 ot\u00e1\u010dania rotora nepresahuje 8,000 RPM a rotor zost\u00e1va tuh\u00fd, sa kompenzuj\u00fa hlavn\u00e9 zlo\u017eky jeho silovej a momentovej nevyv\u00e1\u017eenosti. S na\u0161imi zariadeniami sa stabilne dosahuje zvy\u0161kov\u00e1 \u00farove\u0148 vibr\u00e1ci\u00ed pod 0.01 mm\/s vo frekven\u010dnom rozsahu 3,500 a\u017e 8,000 RPM (v\u00fdsledok sk\u00fa\u0161ky na tomto \u0161pecializovanom vibra\u010dne izolovanom stojane, nie typick\u00fd \u00fadaj z merania v ter\u00e9ne).<\/li>\n
  2. Druh\u00e1 f\u00e1za<\/strong>: N\u00e1sledn\u00e9 vyva\u017eovanie rotora sa vykon\u00e1va pri pracovnej frekvencii, ktor\u00e1 m\u00f4\u017ee v z\u00e1vislosti od kon\u0161trukcie \u010derpadla dosiahnu\u0165 42 000 alebo 60 000 ot\u00e1\u010dok za min\u00fatu. Pri tejto frekvencii, ktor\u00e1 presahuje kritick\u00fa r\u00fdchlos\u0165 ot\u00e1\u010dania, sa rotor st\u00e1va pru\u017en\u00fdm a deformuje sa, \u010do si vy\u017eaduje \u010fal\u0161ie vyva\u017eovacie opatrenia.<\/li>\n<\/ol>\n

    V\u00fdsledky<\/h4>\n

    Zvy\u0161kov\u00e9 vibr\u00e1cie rotora, ktor\u00e9 sa nakoniec dosiahnu v druhom stupni, nepresiahnu 0,3 mm\/s. To zaru\u010duje dlh\u00e9 obdobie bezprobl\u00e9movej prev\u00e1dzky tohto kritick\u00e9ho komponentu. Celkov\u00fd \u010das procesu vyva\u017eovania tohto jedine\u010dn\u00e9ho v\u00fdrobku zvy\u010dajne nepresahuje 30 min\u00fat.<\/p>\n
