にしたことを特徴とするターボ機械の診断装置。[Scope of Claim for Utility Model Registration] A diagnostic device for a turbo machine that rotationally drives a turbine using combustion gas, comprising: a rotation speed sensor that detects the rotation speed of the turbine; A timer for measuring a first deceleration time from when gas supply is stopped until the turbine reaches a first reference rotation speed, and a second deceleration time from when the turbine reaches a second reference rotation speed until it reaches a third reference rotation speed. and, based on the clock signal from this clock means, the first
a first determining means for determining whether the deceleration time is greater than or equal to a predetermined lower limit value and less than or equal to a predetermined upper limit value; and a second determining means,
Diagnosis of a turbomachine characterized in that an abnormality in a rotating part, a bearing part, or a combustion gas supply system of a turbine can be diagnosed when the combustion gas supply is stopped, based on the determination results of the first and second determination means. Device.
