Abstract (en)
A device (20) for cleaning a gas turbine blade (1), comprises: - a vessel (21) suitable for containing a cleaning fluid bath and provided with a header (30); the blade (1) to be cleaned being couplable to the header (30) while the outlet hole (16) of the inner cavity (13) is immersed in the cleaning fluid bath; - a tank (22) suitable for containing the cleaning fluid; - a feed line (24) connecting the tank (22) to the vessel (21); - a return line (25) connecting the header (30) of the vessel (21) to the tank (22); - a first pump (26) designed to draw the cleaning fluid from the tank (22) and send it to the vessel (21) at such a pressure as to produce a flow of cleaning fluid flowing from the outlet hole (16) of the inner cavity (13) to the inlet opening (15) of the inner cavity (13) of the blade (1).
