The following aspects can be used to determine whether the turbine blades need to be replaced:
Appearance inspection: Check whether the blades have obvious cracks, defects, corrosion, etc.
Performance monitoring: For example, monitoring the power, efficiency and other parameters of the turbine. If there is a significant decline, it may mean that there is a problem with the blades.
Vibration analysis: Abnormal vibration may indicate that the structural integrity of the blades is affected.
Material fatigue detection: Detect the fatigue degree of the blade material through professional means.
Regular flaw detection: Use non-destructive flaw detection technology, such as ultrasonic flaw detection, to check whether there are defects inside the blades.
Comparison with standard data: Compare the various indicators of the blades with the established standard data. If they exceed the reasonable range, they may need to be replaced.
