Here's What We Do Better

theoretical tops on alignment

Theoretical Tops On Alignment (Express Alignment) for Internal Steam Turbines from ACQUIP provides an alternative process to perform a tops on/tops off diaphragm alignment on steam turbines.

In order to accomplish an appropriate turbine alignment procedure, it is always necessary to record numerous data points and calculations. At ACQUIP, steam turbine maintenance is planned properly by using correct assembly techniques and laser alignment methods; saving time on the diaphragm alignment process and virtually having a rub-free start up.
Rotor disassembly readings, coupling alignment readings, and internal component positions are recorded at original disassembly. This method allows the shaft alignment to be considered along with the diaphragm alignment in order to reassemble the rotor into the turbine to its original position.

As found diaphragm positions are recorded as well as packing rubs, and shell deviations. All of this data is used to calculate theoretical tops on position. Only tops off data are needed thus reducing work shifts to put on and take the top off of the cylinder.

Express Alignment is a turbine alignment procedure, which is used to collect readings and theoretical data for all internal components. These readings are combined using our laser technology to attain horizontal joint deviations and out of roundness readings.

Only tops off data are needed thus reducing work shifts to put on and take the top off of the cylinder.

The laser alignment readings are ideal for steam turbines with both diaphragms and blade rings. The readings are also recorded on glands, oil bores and nozzles.

Since all turbine components are placed into the calculated ideal position at reassembly, master this approach saves time.

ACQUIP’s alignment engineers and our Express Alignment procedures for Internal Steam Turbines flawlessly, combine our laser alignment tooling and bracketing decreasing the length of your outage and increasing your turbine performance.

Our laser measurement services provide maximum running efficiency and productivity. For more information about our express alignment service contact us at +1 305 538 7101 or email us at info@acquip.com. We also offer equipment rentals to support your team during maintenance projects. Click here

Working with ACQUIP on the job we had in Italy recently was the best experience I have had in this type situation. ACQUIP was very professional and the response time far exceeded my expectations. The rental equipment was in top shape and made it possible for us to take care of our customer in an emergency situation. We will look forward to doing business with you in the future. Thank you for your hard work.

ACQUIP’s engineers performed a great job for Siemens Energy . The Fluid Drive and Gearbox and Pump were all included in the task. Each component was aligned to “all” of Siemens procedures and specifications requested. The Siemens customer was very satisfied with the results of the alignment and process.

First I would like to thank you for your help. We need a piece of alignment equipment on site last minute do to a break down. ACQUIP responded to your request immediately, recommend the right tool for the job, and had the tool on site by 8:30 AM the following morning. Just outstanding customer service and support from the entire ACQUIP team.

ACQUIP was the best choice to rent the Laser Tracker. It speeded up the process! I will definitely come back on our next set of fixtures!

I highly recommend ACQUIP for executing both Tops on/Tops off and Tops off Steam path alignments.
