Detection of a new method for corrosion defects in turbine impeller blades by non-destructive testing

The turbine impeller is a separate component that forms an important part of a turbine. These blades are used to extract energy and play a very important and key role in a turbine. The evaluation of the blades can be evaluated by non-destructive tests depending on their shape and dimensions, and the ability to detect the amount of corrosion in these blades is the main discussion of this article, which was accurately measured by ultrasonic testing method. This defect Due to its high performance in turbines in the oil and water industry, it will be an interesting challenge to test it for non-destructive testing. Corrosion diameter is personalized by ultrasound, which is a new method in this test. An experimental test was performed for turbines with defective blades selected from 100 blades with corrosion defects. 20 blades with more corrosion were selected. Defect signal size and defect size are simulated by Comsol software. According to various tests on the size of the corrosion defect diameter, the approximate life and operating hours of each turbine can be largely determined. The relationship between corrosion defect and its hourly function has a direct relationship and a direct effect on it.
