The characteristic is the current of water diagonal enters the runner and diagonal flows out, runner blade's spool thread and the main axle middle line has an included angle. Has the extension propellor type and decides the propellor two kinds, because its leaf blade is the inclined arrangement, has increased the runner in vivo department basement, compares the axialflow type hydraulic turbine, then allows to arrange the more runner blades, usually is 8-12 pieces. Therefore, its strength ratio axialflow-like must be high, the use flood peak scope compared to axialflow-like high, may achieve flood peak 40-300m, slanting strikes the type hydraulic turbine belongs to the impact one kind, its jet flow middle line and runner's rotation plane has 22.5 the included angle, from pressure tube's water, transforms after the pulverizer into the high speed jet diagonal impact runner, the current of water enters from leaf blade one side, flows out from another one side impels the runner revolving acting. The slanting cock structure is simple, 50 centimeter below runner diameters use the rolling bearing much, 50 centimeter above runner diameters may choose and match sliding bearing its movement to be reliable, the overhaul maintenance is convenient. This hydraulic turbine structure is simple, installs the use maintenance to be convenient.
