とする排気ガスタービン過給機。 The rotor shaft to which the impeller is attached is supported by a thrust bearing, and the pressure at the outlet of the impeller is sealed by an air labyrinth patch provided between the outer circumference of the back surface of the impeller and the bearing stand. In an exhaust gas turbine supercharger that forms a seal space between the bearing stand and the fin, the meshing allowance of the fins of the air labyrinth packing is set to be smaller than the minimum clearance between the rotating body of the rotor and the casing, etc. , the exhaust gas turbine is characterized in that it is equipped with a thrust bearing damage detection device comprising a pressure detector that detects the pressure in the seal space and a controller that trips the engine based on a detection signal from the pressure detector. feeding machine.
