KAPLAN TURBINE

Kaplan turbine is a low-descent overpressure turbine with axial runner spraying. The horizontal/vertical variant is chosen subject to the flow rate and descent height parameters. The runner consists of a hub with 3-5 blades with adjustable direction. Water is fed to the runner by a race wheel equipped with adjustable or fixed position blades. The correct relative position of the runner blades and the guide blades allows for optimum utilisation of the working water energy for high turbine efficiency. Due to the number of variants (straight flow, bend, bulb, vertical, with transmission, with flat belt, direct connection to generator) this is the most variable technical design in the world of turbines.

Kaplan Turbines CHP Are Made for Following Parameters:

Descent heights 1 – 20 m
Flow rates up to 50m3/s per unit
Mainly straight flow horizontal and fountain vertical variants.
Runner diameters 500 to 3,000 mm, 3, 4 or 5 blades
Runner blades made of special bronze alloy or hard stainless steel (according to client requirement)
Excellent efficiency within partial load range thanks to two-stage regulation fully comparable to global competitors
Hydraulic regulation drive
Guide system capable of full turbine closing
Compact structure with minimum spatial requirement
Easy installation thanks to modular structure
Horizontal variants bulb or with flat belt
Vertical variant with front transmission or flat belt
Connection options with square or circular flange to pipeline or concrete raceway
Maintenance-free shaft seal with ceramic plug
Raceway or suction of metal or concrete
