Steam turbine internal alignment applications require high precision, ease of use and reliability. The Easy-Laser® E960 system is used to align diaphragms and internal components and delivers all these things.
Setup is fast and simple. There is no need to precisely center your detector to the bore or the laser to the rotor to perform position checks. Simply orient the sensor into laser range, and the display unit does the rest to calculate the center. Your rotor positions are entered digitally for greater accuracy and speed of setup. Wireless components streamline the setup—no cables to get in the way!
Take three points over 180 degrees on a bore just as you would with a tight wire, or use the multipoint measurement to find the center of bores and check for ovality.
The Easy-Laser E960 features an optional reference control sensor for greater reliability and precision. No more guessing whether your reference line (the laser beam), moved during measurement—you are in control of its position at all times. Even if the beam moves over time due to environmental factors, the reference control sensor allows the system to automatically adjust for such movement to ensure all your readings stay highly accurate.
Need to measure the flatness of the shell? Simply add the D22 rotating laser and flatness readings can be taken using the same sensor as the one you use for internal bore alignment. Both the top and bottom shell can be measured without having to remove the bolts.
This system works with your existing processes. The Easy-Laser E960’s intuitive display allows for entry of diaphragm positions into your excel spreadsheets or take advantage of the included Easy-Link software to present, process and document the turbine alignment in one complete and easy to use package.

SOLAR gas turbine centering tool with X-Y tracking
The centering tool for SOLAR TURBINES is based upon shaft travel in the vertical plane. As the top knob is turned, a plunger pushes the shaft from the top position all the way down to the bottom position. The tool allows the technician to count the number of turns of the top knob to determine the amount of travel of the shaft. Upon traversing the full extent of the travel range from top to bottom, the technician then applies only half the number of turns in the opposite direction to return the shaft to the center of its vertical travel range. Performing this task with the ROTALIGN ULTRA laser shaft alignment system allowed this job to be performed much more accurately. The laser/sensor combination takes the centering of the shaft to a new dimension by tracking not only the shaft’s vertical position but its horizontal position as well.

The Williamson Free School of Mechanical Trades’ Power Plant Technology Program recently obtained an OPTALIGN tool, a high tech laser alignment system, from LUDECA, Inc, a company in Doral, FL, that specializes in predictive maintenance solutions. Don Meredith, of Precise Vibration and Alignment, Inc., spent a morning training power plant technology seniors and juniors in the use of the new system, which is used for turbine shaft alignment. The systems are important because good alignment helps turbines last longer.
John Beaudry, director of power plant technology, said, “We are really excited about this new laser alignment system. It will help us out tremendously in saving money and prolonging the lifespan of our turbines. Don’s training was the best introductory training session we have had yet. The students got a lot out of it. We are very excited to be developing a relationship with LUDECA, the company is known as the industry standard in laser alignment systems.”
Beaudry added that the system will be used in a shaft alignment course and will be an asset as more equipment is purchased for the Energy Island upgrade.
“This system will help us repair and maintain equipment in-house, such as the new turbines we will be purchasing. This will save us a lot of time and money and will provide good experience for our students.”
