    摘要： A measurement system measures a gap between a plurality of rotating bucket tips and a stationary shroud surface. The system includes a sensor secured to the shroud surface, where the sensor senses a distance between each of the rotating bucket tips and the shroud surface, and a key phasor indexing each of the plurality of rotating bucket tips. A processor receives data from the sensor and the key phasor and calculates a shift against each of the plurality of buckets. The processor determines a time to bucket replacement based on current service hours of the plurality of rotating buckets tips.

    摘要翻译： 测量系统测量多个旋转铲斗前端和固定护罩表面之间的间隙。 该系统包括固定到护罩表面的传感器，其中传感器感测每个旋转铲斗前端和护罩表面之间的距离，以及将多个旋转铲斗前端中的每一个分开的按键相量。 处理器从传感器和键相量接收数据，并计算针对多个桶中的每一个的移位。 处理器基于多个旋转铲斗尖端的当前服务时间确定铲斗更换的时间。

    摘要： A monitoring system for monitoring, in real time, a gap between a rotating portion and a stationary portion of a machine. The monitoring system includes an imaging device for forming a reference image of the gap and one or more next images of the gap, the imaging device including a portion disposed within the machine and a portion external to the machine. The system also includes an image processor coupled to the imaging device configured to monitor whether the gap is increasing or decreasing by comparing the reference image to the one or more next images.

    摘要： A nozzle for a turbine system is disclosed. The nozzle includes an airfoil, an inner sidewall, and an outer sidewall. The airfoil includes exterior surface defining a pressure side and a suction side extending between a leading edge and a trailing edge. The airfoil further defines a tip and a root. The inner sidewall is connected to the airfoil at the tip. The outer sidewall is connected to the airfoil at the root. The inner sidewall and outer sidewall each includes a peripheral edge defining a pressure side slash face, a suction side slash face, a leading edge face, and a trailing edge face. At least one of the inner sidewall pressure side slash face, the inner sidewall suction side slash face, the outer sidewall pressure side slash face, or the outer sidewall suction side slash face has a generally curvilinear profile.
