3 Terms and definitions

The terms and definitions defined in GB/T 19873.1 and the following apply to this document. 3.1 Turbine blade turbineblade A heavy object used in turbine machinery (such as steam turbines, gas turbines, water turbines, etc.) to guide the fluid to flow in a certain direction and drive the rotor to rotate. Required parts. Note. The blades mounted on the casing are called stationary blades or guide vanes, and the blades mounted on the rotor are called moving blades. Flat flow capacity. 3.2 Tip-timing The time it takes for the blade to reach the sensor during the rotation of the blade. The blade tip timing sensor is installed on the casing of a large turbine machine, and the sensor measures The time it takes for each blade to arrive at the sensor. 3.3 Speed sensor speedsensor A sensor that converts the speed of a rotating object into an electrical output. 3.4 The smallest physical change in displacement that a sensor can detect. 3.5 responsivebandwidth The maximum sine wave frequency to which the servo system can respond. ......
