2 Odst\u0159ediv\u00e9 \u010derpadlo<\/p>\n
Principem \u010dinnosti odst\u0159ediv\u00e9ho \u010derpadla je odst\u0159ediv\u00fd pohyb. Odst\u0159ediv\u00fd pohyb je vlastn\u011b projevem setrva\u010dnosti objektu. Nap\u0159\u00edklad kdy\u017e se kapky vody na de\u0161tn\u00edku pomalu ot\u00e1\u010dej\u00ed, kapky vody se ot\u00e1\u010dej\u00ed spolu s de\u0161tn\u00edkem. Je to proto, \u017ee t\u0159en\u00ed mezi de\u0161tn\u00edkem a kapkami vody p\u016fsob\u00ed na kapky vody jako dost\u0159ediv\u00e1 s\u00edla. Pokud se v\u0161ak de\u0161tn\u00edk ot\u00e1\u010d\u00ed rychleji, t\u0159en\u00ed nesta\u010d\u00ed k tomu, aby se kapky vody pohybovaly kruhov\u00fdm pohybem. Pak se kapky vody od de\u0161tn\u00edku odtrhnou a pohybuj\u00ed se k vn\u011bj\u0161\u00edmu okraji, podobn\u011b jako kdy\u017e pomoc\u00ed lana t\u00e1hnete k\u00e1men, aby vykonal kruhov\u00fd pohyb. Pokud je rychlost p\u0159\u00edli\u0161 vysok\u00e1, provaz se p\u0159etrhne a k\u00e1men vylet\u00ed ven. Jedn\u00e1 se o tzv. odst\u0159ediv\u00fd pohyb.<\/p>\n
P\u0159i pr\u00e1ci odst\u0159ediv\u00e9ho \u010derpadla poh\u00e1n\u011bj\u00ed vysokorychlostn\u00ed rotuj\u00edc\u00ed lopatky ob\u011b\u017en\u00e9ho kola kapalinu, kter\u00e1 se ot\u00e1\u010d\u00ed a vyl\u00e9v\u00e1 ven, \u010d\u00edm\u017e je dosa\u017eeno \u00fa\u010delu p\u0159epravy.

Kdy\u017e se ob\u011b\u017en\u00e9 kolo rychle ot\u00e1\u010d\u00ed, lopatky zp\u016fsobuj\u00ed rychlou rotaci kapaliny. Rotuj\u00edc\u00ed kapalina vyl\u00e9t\u00e1 z ob\u011b\u017en\u00e9ho kola p\u016fsoben\u00edm odst\u0159ediv\u00e9 s\u00edly. Po vyvr\u017een\u00ed kapaliny z v\u00fdv\u011bvy se ve st\u0159edu ob\u011b\u017en\u00e9ho kola vytvo\u0159\u00ed podtlakov\u00e1 oblast. Vn\u011bj\u0161\u00ed kapalina je vtla\u010dov\u00e1na do p\u0159\u00edvodn\u00edho potrub\u00ed vody potrubn\u00ed s\u00edt\u00ed p\u016fsoben\u00edm atmosf\u00e9rick\u00e9ho tlaku a lze dos\u00e1hnout plynul\u00e9 dopravy.<\/p>\n

\u0160roubov\u00e9 \u010derpadlo je nov\u00fd typ \u010derpadla, kter\u00e9 pracuje na principu rota\u010dn\u00edho v\u00fdtlaku. Hlavn\u00edmi pracovn\u00edmi \u010d\u00e1stmi jsou excentrick\u00fd \u0161roub (rotor) a pevn\u00e9 pouzdro (stator).

M\u00e9dium je tla\u010deno a proud\u00ed rovnom\u011brn\u011b v axi\u00e1ln\u00edm sm\u011bru, vnit\u0159n\u00ed rychlost proud\u011bn\u00ed je n\u00edzk\u00e1, objem z\u016fst\u00e1v\u00e1 nezm\u011bn\u011bn a tlak je stabiln\u00ed, tak\u017ee nevznikaj\u00ed v\u00ed\u0159iv\u00e9 proudy a m\u00edch\u00e1n\u00ed.<\/p>\n
