Abstract:
A method and a device to counteract wear about a guide vane (16) from a particle bearing drive water, the guide vane (16) being arranged in a guide vane housing (14) in a water turbine (1), and where the method comprises: —routing a supply channel (36) for water cleaner than the drive water to the attachment point area between the guide vane (16) and the guide vane housing (14); and—leading water cleaner than the drive water to flow through a slit (28) where the slit (28) at least partly encircles the guide vane (16).
