NXA SIEMENS

Shaft alignment in the wind power Industry

The NXA SIEMENS is custom-made with firmware and fixtures designed specifically for Siemens 2.3, 2.4, 2.6, 3.6, and 4.0. These precisely designed fixtures make generator-to-gearbox alignment easy inside any nacelle – safeguarding reliability and optimizing the energy efficiency of the wind turbine.

Features

Horizontal Alignment
Measures and helps correct misalignment while dual sensors maintain the true position of the shafts, even as unintended movements are experienced during the alignment process
Vertical Alignment
Same power and ease of use as the Horizontal Alignment program. The vertical alignment program is used when aligning flanged-mounted machines
Verti-Zontal
Allows for the vertical and horizontal adjustments to be made together in one pass, saving valuable time and ensuring accuracy the first time around
Machine Train
Machine Train routine simplifies the complexity of aligning multiple units with connecting shafts
Spacer Shaft
The Spacer Shaft program simplifies spacer shaft alignment by showing both ends of the spacer shaft coupling with an angle/angle display
OmniView
Changes the on-screen orientation to match what the user is actually seeing, tracking the user’s position relative to the machine being aligned

Horizontal Machines

The Acoem NXA Pro is perfect for measuring horizontal alignment conditions but its real power is in helping correct misalignment. The dual sensors allow the NXA Pro to maintain the true position of the shafts, even as unintended movements are experienced during the alignment process.

Vertical Machines

The same power and ease of use found in the horizontal alignment program can be found in the vertical alignment program. The vertical alignment program is used when aligning flanged-mounted machines. The gyroscopes in the NXA Pro’s sensors allow the system to accurately measure the angles using the Tripoint Method of measurement, an industry first !

Machine Train

The NXA Pro’s machine train routine simplifies the complexity of aligning multiple units with connecting shafts. The software includes a “minimal moves” function which identifies the best reference machine to minimize the number of moves required to complete the alignment.

Spacer Shaft

With spacer shafts there are two power planes of transmission that need to be aligned to the correct tolerances. The NXA Pro spacer shaft program simplifies the process showing both ends of the spacer shaft coupling with an angle/angle display. The alignment is completed using the Verti-Zontal™ move.
