  runner chamber
Fastening the removable sector of the runner chamber of an adjustable-blade turbine
      


In China many hydraulic turbines have been eroded by solid particles in water flow. Forpropeller turbines mast components can now be succesfully protected by nonmetalic coatings. Howeverthe coatings on the suction side of blade and middle part of runner chamber are often quickly eroded.It is found that the erosion is offen caused by combined action of sand abrasion and cavitation. some measures for solving this problem are suggested.
