Moment Blade Weighing Testing
Moment weighing is a technique for locating an object’s center of gravity.
Moment weighing is a technique for locating an object’s center of gravity.
During moment weighing, blade weight and the center of gravity location (CoG) are measured and analyzed with a proprietary software package to determine the optimum blade stacking position (loading chart) that minimizes blade row unbalance.
Blades need to work under a high-load, high-speed, and high-vibration environment, which directly affects the start-stop performance, working reliability, efficiency, and operating costs for a business. Turbine blades have the characteristics of complex shapes and high precision requirements.
In order to meet the technological requirements, the blades need to be manually polished, so that the mass moment of each blade after assembly is unique, providing an intentional residual imbalance in the rotating body.
To match the blade specifications for partnering businesses, SimuTech Group has moment weighed turbine blades ranging in length from 1 to 60 inches, spanning multiple industries and application categories.
