Vyva\u017eovanie vysokor\u00fdchlostn\u00fdch rotorov vo v\u00e1kuov\u00fdch \u010derpadl\u00e1ch si vy\u017eaduje \u0161pecializovan\u00e9 vybavenie schopn\u00e9 zachova\u0165 presnos\u0165 v extr\u00e9mnych prev\u00e1dzkov\u00fdch podmienkach. Na splnenie t\u00fdchto po\u017eiadaviek boli v rokoch 2002 a 2009 vyvinut\u00e9 \u0161pecializovan\u00e9 vyva\u017eovacie stojany.

Stojan je postaven\u00fd na obd\u013a\u017enikovej plo\u0161ine (1), podopretej \u0161tyrmi valcov\u00fdmi pru\u017einami (2), ktor\u00e9 zabezpe\u010duj\u00fa izol\u00e1ciu vibr\u00e1ci\u00ed. Plo\u0161ina je vystu\u017een\u00e1 pozd\u013a\u017enymi a prie\u010dnymi v\u00fdstuhami, \u010d\u00edm sa dosahuje vysok\u00e1 tuhos\u0165 a z\u00e1rove\u0148 minimalizuje hmotnos\u0165. Toto kon\u0161truk\u010dn\u00e9 rie\u0161enie zais\u0165uje vysok\u00fa citlivos\u0165 na sily nevyv\u00e1\u017eenosti a zabra\u0148uje rezonan\u010dn\u00fdm kmitom v celom rozsahu ot\u00e1\u010dok \u010derpadla po\u010das vyva\u017eovania.<\/p>\n

Mont\u00e1\u017ena z\u00e1klad\u0148a (3) je pevne pripevnen\u00e1 k plo\u0161ine a sl\u00fa\u017ei na presn\u00e9 umiestnenie \u010derpadla (4). \u010cerpadlo je uzavret\u00e9 v kryte (5), v ktorom je tie\u017e umiestnen\u00fd sn\u00edma\u010d f\u00e1zov\u00e9ho uhla (6). Na kryte a z\u00e1kladni s\u00fa namontovan\u00e9 dva sn\u00edma\u010de vibr\u00e1ci\u00ed (7 a 8). V\u0161etky sn\u00edma\u010de s\u00fa pripojen\u00e9 k meracej a v\u00fdpo\u010dtovej jednotke (9), ktor\u00e1 vykon\u00e1va anal\u00fdzu v re\u00e1lnom \u010dase a vypo\u010d\u00edtava korek\u010dn\u00e9 z\u00e1va\u017eia.<\/p>\n

Postup vyva\u017eovania<\/h2>\n

Vyva\u017eovanie sa vykon\u00e1va v dvoch postupn\u00fdch f\u00e1zach, aby sa zabezpe\u010dila presnos\u0165 za podmienok tuh\u00e9ho aj pru\u017en\u00e9ho rotora.<\/p>\n

F\u00e1za 1 \u2013 Vyva\u017eovanie tuh\u00e9ho rotora<\/h3>\n

V po\u010diato\u010dnej f\u00e1ze sa rotor \u010derpadla vyva\u017euje pri ot\u00e1\u010dkach do 8,000 rpm, ke\u010f sa spr\u00e1va ako tuh\u00fd rotor. Cie\u013eom je kompenzova\u0165 statick\u00fa aj momentov\u00fa nevyv\u00e1\u017eenos\u0165. Pri sk\u00fa\u0161kach na tomto vibra\u010dne izolovanom stojane syst\u00e9m dosahuje \u00farovne zvy\u0161kov\u00fdch vibr\u00e1ci\u00ed pod 0.01 mm\/s RMS vo frekven\u010dnom rozsahu 3,500\u20138,000 rpm. T\u00e1to mimoriadne n\u00edzka hodnota je v\u00fdsledkom sk\u00fa\u0161ky na stojane z\u00edskan\u00fdm za kontrolovan\u00fdch podmienok, nie typick\u00fdm \u00fadajom z merania v ter\u00e9ne.<\/p>\n

F\u00e1za 2 \u2013 Vyva\u017eovanie vysokor\u00fdchlostn\u00e9ho flexibiln\u00e9ho rotora<\/h3>\n

V druhej f\u00e1ze sa vyva\u017eovanie vykon\u00e1va pri prev\u00e1dzkov\u00fdch ot\u00e1\u010dkach rotora \u2013 bu\u010f 42 000 alebo 60 000 ot.\/min. v z\u00e1vislosti od modelu \u010derpadla. Pri t\u00fdchto ot\u00e1\u010dkach rotor prech\u00e1dza do pru\u017en\u00e9ho stavu a deformuje sa, \u010do vedie k \u010fal\u0161ej dynamickej nerovnov\u00e1he. Na minimaliz\u00e1ciu t\u00fdchto \u00fa\u010dinkov sa vypo\u010d\u00edta a aplikuje kone\u010dn\u00e1 korekcia.
