Vliv geometrie p\u0159edm\u011btu na \u00fa\u010dinnost \u010di\u0161t\u011bn\u00ed<\/h3>\n

Geometrie p\u0159edm\u011btu hraje kl\u00ed\u010dovou roli v \u00fa\u010dinnosti ultrazvukov\u00e9ho \u010di\u0161t\u011bn\u00ed.

Vliv frekvence ultrazvuku<\/h3>\n

Frekvence ultrazvuku ovliv\u0148uje hloubku pronik\u00e1n\u00ed vln do materi\u00e1lu a do slep\u00fdch otvor\u016f. Ni\u017e\u0161\u00ed frekvence (nap\u0159. 25 kHz) umo\u017e\u0148uj\u00ed hlub\u0161\u00ed pronik\u00e1n\u00ed, ale s ni\u017e\u0161\u00ed intenzitou kavitac\u00ed.

Optim\u00e1ln\u00ed frekvence se vol\u00ed podle typu ne\u010distot a geometrie p\u0159edm\u011btu. Pro \u010di\u0161t\u011bn\u00ed slep\u00fdch otvor\u016f se \u010dasto doporu\u010duj\u00ed ni\u017e\u0161\u00ed frekvence, kter\u00e9 umo\u017en\u00ed proniknut\u00ed do hlub\u0161\u00edch \u010d\u00e1st\u00ed otvoru.<\/p>\n

Polohov\u00e1n\u00ed a orientace p\u0159edm\u011btu v ultrazvukov\u00e9 l\u00e1zni je kritick\u00e9. P\u0159edm\u011bty by m\u011bly b\u00fdt um\u00edst\u011bny tak, aby byly vystaveny ultrazvukov\u00fdm vln\u00e1m ze v\u0161ech stran. V p\u0159\u00edpad\u011b slep\u00fdch otvor\u016f je d\u016fle\u017eit\u00e9 zajistit, aby otvor nebyl p\u0159ekryt jin\u00fdmi \u010d\u00e1stmi p\u0159edm\u011btu, ani dnem n\u00e1dr\u017ee. Optim\u00e1ln\u00ed orientace minimalizuje st\u00edn\u011bn\u00ed a maximalizuje \u00fa\u010dinnost \u010di\u0161t\u011bn\u00ed.
