Problem: The operating head of the power station is high (the maximum operating water head is 1037m). The runner bucket had been broken many times, and the unit shuts down frequently, causing serious damages to other components of the turbine and affecting the stable operation and service life of the turbine.
New Runner model:CJA475B-L-165/2×10.5
Solution: The new runner was custom designed according to the hydraulic parameters of the power station. Has very good hydraulic and anti-cavitation performance under high head operation. The new runner had no cracks after working for many years, and it can ensure high efficiency when working with single or double nozzle. These improvements directly increased the revenue of the power station.
