The Fixturlaser 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.
Fixturlaser shaft alignment tools offer the wind power industry:
The Machine Defined Data function allows the user to create configuration templates for all kinds of manufacturing models, where data like distances, target values, and tolerances can be saved. This function is particularly useful for service organizations that maintain several turbine models.
The Fixturlaser NXA SIEMENS is perfect for measuring horizontal alignment conditions but its real power is in helping correct misalignment. The dual sensors allow the NXA SIEMENS to maintain the true position of the shafts, even as unintended movements are experienced during the alignment process.
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 SIEMENS’s sensors allow the system to accurately measure the angles using the Tripoint Method of measurement, an industry first!
The NXA SIEMENS’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.
This program calculates the appropriate target values for an alignment based on the machine’s hot condition and ambient condition. The ultility retrieves two saved shaft alignment measurements — one in the machine’s cold, or ambient condition and one in the hot conidition — and then calculates the appropriate target values. Those values can be used the next time to ensure proper alignment at running conditions.
We have a wide range of fixture applications. The fixtures have a solid design and are easy to mount. While originally designed for a specific manufacturer’s turbine, the fixtures will fit on most wind power turbines in the market place.
Softcheck™ checks if there is a soft foot condition, i.e. when the motor is not resting firmly on all its feet.
This program allows the user to test alternate solutions in situations where the movable machine is base bound or bolt bound.
Allows the system to compensate for pre-determined alignment targets. The user can establish targets using this function and then go directly to shaft alignment.
The NXA Siemens’s data management function. Measurements can be organized in folders and subfolders. Single measurements and/or complete data structures can be copied to USB stick.
A set of machine configuration templates for storing data for individual machines.
Opens a window for activating or deactivating OmniView, the feature that changes the on-screen orientation to match what the user is actually seeing, tracking the user’s position relative to the machine being aligned.
Allows the user to modify the sampling time of the sensor readings. Also offers the ability to run a repeatability test to determine if the vibration from nearby machines is affecting the data quality of the alignment.
Allows the user to adjust the resolution, dependent upon how precise the alignment needs to be.
We train customers to use the Verti-Zontal alignment process, taking the final measurement with the sensors at 3:00 or 9:00 taking live reading. But if the situation doesn’t allow easily positioning the sensors at 3:00 or 9:00 the Extended Alignment utility can address the problem. Extended Alignment allows for live readings as long as the sensors are within +/- 45 degrees of the 3:00 or 9:00 position. Extended Alignment can also be used when making live vertical adjustments of machines mounted on adjustable chocks.
Target Values Clock converts thermal expansion targets given as dial, or clock, values (target rim/face, or target reverse dial), to alignment values consistent with Fixturlaser alignment tools – angle and offset.
Allows easy creation of reports which can include text and alignment results files. Reports are stored in the measurements folder and can be downloaded to a USB stick for delivery. The logo and field names are customizable.
This utility, when coupled with the Fixturlaser NXA Runout Probe (sold separately), displays the live readings from the probe.
This utility, when coupled with the Fixturlaser Runout Probe (sold separately), displays the minimum and maximum values detected by the probe.
