Abstract

The utility model relates to turbine blade technical field, concretely is a kind of turbine erosion-resistant turning moving blade, including sheet component, install in the erosion-proof liquid discharge component of sheet component last stage;The sheet component includes soldering inner end and blade main body, the one side of blade main body is fixedly installed with reinforcing rib, and reinforcing rib is internally provided with through-hole, the inside of through-hole is inserted with the rod of muscle, and the end of rod of muscle is clamped in the inside of soldering inner end and is passed to the one end of through-hole outside. By the blade of traditional whole set structure is set to three-section soldering inner end, soldering outer end and blade main body, when the multiple blade main bodies of uniform distribution are driven by impeller to carry out high-speed rotation, steam water droplet entrained impurity can be quickly transported to last stage along the arc surface of blade main body, and finally the water droplet and impurity of last stage will be quickly discharged from erosion-proof liquid discharge component outward, to effectively ensure that blade main body and its last stage keep dry and clean at all times.
