- W2380368270 abstract "Dongzhuang Reservoir Power Station operates with high water head and wide amplitude. The sediment concentration passing through the turbines is high and the wet components of the turbines will be suffered abrasion damage. Learning from the Yellow River Xiaolangdi,Xixiayuan,Wanjiazhai Hydropower Station and other heavy sediment turbine parameters,it selected and adopted the anti abrasion measures. It analyzed the main parameters of power station,from the guaranteeing safe operation and reducing abrasion damage point of view and initially selected Dongzhuang Power Station turbines rated than speed,coefficient of speed ratio,unit speed,unit flow and other parameters. Prototype turbine parameters are as follows: Model: HL( 114)- LJ- 230; Rated output Nr= 41. 1 MW; rated head Hr= 181 m; runner diameter D1= 2. 3 m; rated flow Qr=25. 25 m3/ s; rated efficiency ηr= 91. 5%; rated speed n r= 375 r / min; suction height H s=- 5. 88 m; apparatus cavitation coefficient σZ= 0.083 3; specific speed ns= 114 m·kW; Coefficient of speed ratio k = 1 539." @default.
