3D Laser Alignment and Measurement Solutions for Hydro 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.

Hydro turbine laser alignment services and precision measurement solutions include 3D alignment, turbine geometry and dimensional analysis, large part inspections, reverse engineering, geometric dimensioning, tolerancing, levelness, plumbness, flatness, straightness, concentricity, parallelism, circularity, cylindricity, perpendicularity and more for Impulse and Reaction type turbines including Francis Hydro Turbines, Kaplan Hydro Turbines, Pelton Hydro Turbines and others.

NIST Traceable

ROTATEK utilizes Laser Trackers that are NIST Traceable and measurement results are documented in a detailed graphical report.

Turbine Geometry

Turbine geometry is measured with the laser tracker for fast and accurate dimensional analysis of critical parts.

Geometric Alignment

Alignment of large turbine components are easily measured and precision moves can be monitored live.

Levelness and Flatness

Accurate laser tracker measurements can quickly verify each turbine component meets levelness and flatness tolerances to ensure a reliable installation.

Bore Alignment

Bearings and stationary turbine components are accurately aligned to reduce unwanted vibration and ensure safe, reliable and efficient hydro turbine operation.

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.
