Original abstract
The contribution is aimed on the analysis of Y(Q) characteristic of centrifugal pump. The main attention is concentrated on the impeller of high specific speed, especially on the diagonal pumps. It is derived, that stability of Y(Q) curve depends on the dissipative function. The analysis concludes that very important is the design of the interior of spiral case and distributor to achieve a stable Y(Q) characteristic curve.

Příspěvek je zaměřen na analýzu stability Y(Q) charakteristiky odstředivého čerpadla. Zvláštní pozornost je zaměřena na čerpadla vysokých rychlostí, zejména diagonální. Prokazuje se, že zmíněná stabilita závisí významnou měrou na disipační funkci. Z rozboru vyplývá, že je nutno zvláštní pozornost věnovat návrhu interiéru spirálního tělesa a rozvaděče z hlediska závislosti disipační funkce na průtok.
