3-D Laser Alignment and Measurement Solutions for Steam Turbines
Unlike traditional alignment methods using piano wire, alignment telescopes and 2d laser optics, ROTATEK field engineers utilize 3D portable coordinate measuring machines (PCMM) including Laser Trackers and Articulating Arms for unparalleled accuracy, precision and measurement acquisition time.
Steam turbine laser alignment service and precision measurement solutions include 3D Tops On/Tops Off internal diaphragm alignment, Tops On alignment, turbine geometry and dimensioning, shaft alignment, horizontal and vertical joint surface mapping, crossover piping dimensioning, dimensional analysis, large part inspections, reverse engineering, geometric dimensioning, tolerancing, levelness, flatness, straightness, concentricity, parallelism, circularity, cylindricity, and more.
Internal Bore Alignment
Bearings, diaphragms and stationary turbine components are accurately aligned to reduce unwanted vibration and ensure safe, reliable and efficient steam turbine operation.
Levelness and Flatness
Accurate laser tracker measurements can quickly measure horizontal shell casing joints to verify levelness and flatness tolerances are met to ensure a reliable distortion free installation.
Geometric Alignment
Alignment of large turbine components are easily measured and precision moves can be monitored live.
Turbine Geometry
Turbine geometry is measured with the laser tracker for fast and accurate dimensional analysis of critical parts.
3-D Measurements
Laser trackers operate by measuring two angles and a distance. The tracker sends a laser beam to a retroreflective target held against the object being measured. As light is reflected off the target, it bounced back and re-enters the tracker at the same position it left and is measured by a distance meter, measuring the distance between the tracker and target.
Distance Measurement
The tracker sends a laser beam to a retroreflective target held against the object to be measured. The reflectedbeam returns to the tracker and its precise distance is recorded.
3D Measurement
Two angle encoders measure the elevation and rotational angles while a highly accurate absolute distance meter is used to determine the 3D position of the target. This position is shown in the software as an X, Y, Z value.
Tracking
The target returns the reflected laser beam parallel but offset back to the tracker where it hits the position detector, which calculates the offset between the outgoing and incoming beam. Servo motors continuously (thousands of times per second) steer the tracker’s head to minimize the offset between the two beams, resulting in high-speed, dynamic measurements.
