Dimensional metrology of gas and steam turbines is the practice of calibrating equipment to achieve optimum quality control during the installation or realignment process. Modern technology has provided premium tools to achieve the highest level of precision measurement, one of which is the laser tracker.
For many, understanding the alignment process of a turbine can be difficult to grasp, so in this video we will discuss three integral aspects of the alignment procedure on gas and steam turbines.
First of all, control points are critical to maintaining precision throughout the process. Control points are placed around the area of inspection and used to define the integrity of the data collected. Upon completion of inspecting the turbine the measurement loop is closed by checking back into these original control points. This confirms that our degree of measurement error is within tolerance.
Next, the measuring equipment can not be restricted by gravity. In other words, up and down must be in reference to the orientation of the turbine. Our measurement method with the laser tracker is able to calculate axis points directly related to the orientation of the turbine, not gravity.
Finally, setting itself apart from other optical alignment methods, our metrology system gathers data from the laser tracker to a high end measurement software which then processes that data into a three dimensional framework. That data can then be analyzed for fast alignment calculations. The benefit of our digital process is that all data is gathered faster and the overall alignment process takes less time to perform.
