HYDRO TURBINE EQUIPMENT FOR LOW-CAPACITY HYDRAULIC POWER PLANTS

摘要

1. The actual standard range of the flow channels in hydro turbines and the corresponding power output and head ranges in low-power HPPs can functionally be covered using eight sets of rotors. 2. The rotor type within each series can be selected on the condition of minimized parameter M, which is the reciprocal of the power-speed coefficient. 3. Nominal diameters for RO-type hydro turbines can be established using K_D = 1.17, and for PL-type turbines―using K_D= 1.38. 4. The limiting head value for reaction hydro turbines to provide a positive suction head is 180 m. 5. The maximum rotor diameter for its single-piece transportation from the manufacturer should not exceed 190 cm.
