HYDRO TURBINE Alignment and Measurement Solutions

Rotatek offers innovative solutions for the installation, alignment and inspection of vertical hydro turbines. Utilizing an application specific hydro power alignment system, NIST traceable laser tracker system, and precision measurement gauges Rotatek’s precision hydro turbine services offer significant advantages over traditional methods like plumb lines, spirit levels, and manual gauges.

Hydro Turbine Alignment is is critical to ensure that the rotor and stator components are concentric and that the axial and radial clearances between the rotating and stationary components are within acceptable limits.

Unlike traditional alignment methods using a straight edges, or dial indictors, ROTATEK field engineers utilize state-of-the-art laser equipment for unparalleled accuracy, precision and measurement acquisition time.

Industrial turbine alignment is a complex process that requires careful planning, attention to detail and highly skilled operators in order to achieve accurate, reliable results in a timely and efficient manner.

Shaft Plumbness and Runout

Utilizing an application specific hydro power alignment system, Rotatek can measure angular deviations with high accuracy (often within arc-seconds), ensuring precise alignment of turbine components relative to gravity.

BORE ALIGNMENT

Alignment of the guide bearings and stationary machine components are easily measured no matter how large and precision moves can be monitored live.

FOUNDATION AND THRUST BEARING LEVELNESS AND FLATNESS

Advanced laser tracker technology and innovative measurement solutions allows Rotatek to perform levelness and flatness measurements with unparalleled accuracy, precision and speed.

3D 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.
