Original abstract
This paper is aimed at differences in designs of spiral case and impeller of mixed flow pump with regard to suppression of Y – Q characteristic curves instability, pressure pulsations and especially to achieving necessary delivery head. The differences between new and old conception will be explained. The reasons of these differences with regard to flow in pump interior, hydraulic losses, static pressures and velocities will be explained as well.
Czech abstract
Tato práce je zaměřena na rozdíly v návrzích spirály a oběžného kola diagonálního čerpadla s ohledem na potlačení nestability Y – Q charakteristiky, tlakových pulsací a zejména dosažení potřebné dopravní výšky. Budou vysvětleny rozdíly mezi novým a starým pojetím koncepce čerpadla. Stejně tak budou vysvětleny rozdíly s ohledem na proudění v interiéru čerpadla, hydraulické ztráty, statické tlaky a rychlosti.
