预测燃气涡轮机剩余使用寿命的系统
摘要：
本发明涉及一种预测燃气涡轮机剩余使用寿命的系统。一种用于生成定位在涡轮机内的涡轮机部件的红外图像的闪光热成像设备，其中，涡轮机包括至少一个检查通道。所述设备包括：闪光源，其生成加热涡轮机部件的光脉冲；以及红外传感器，其用于检测由涡轮机部件辐射的热能量。所述设备还包括管道镜，其具有传感器端部、包括闪光源的观察端部、以及在传感器和观察端部之间延伸的内部中空部。管道镜被安置在检查通道中，使得观察端部被定位在涡轮机内。由涡轮机部件辐射的热能量通过中空部被传输到红外传感器，以使得能够生成红外图像。所述设备进一步包括定位在观察端部上的反射器，其引导光脉冲朝向涡轮机部件；以及用于为所述闪光源供电的闪光电源。
摘要（英）：

The invention relates to a system to prognose gas turbine remaining useful life. A flash thermography device for generating an infrared image of a turbine component located inside a turbine, wherein the turbine includes at least one inspection port. The device includes a flash source that generates a light pulse that heats the turbine component and an infrared sensor for detecting thermal energy radiated by the turbine component. The device also includes a borescope having a sensor end, a viewing end that includes the flash source and an interior hollow that extends between the sensor and viewing ends. The borescope is positioned in the inspection port such that the viewing end is located inside the turbine. Thermal energy radiated from the turbine component is transmitted through the hollow to the infrared sensor to enable generation of the infrared image. The device further includes a reflector located on the viewing end that directs the light pulse toward the turbine component and a flash power supply for energizing the flash source
