Alignment of vertical turbine shafts is a crucial part of maintenance in hydro power production. The cumbersome task involving wires, oil-filled cans and sound micro meters may now be a part of industrial history. With the new Fixturlaser VSP measurement system, alignment of vertical turbine shafts becomes a quick and easy way to achieve high accuracy at a minimum of time and cost. The laser based Fixturlaser VSP system uses traditional measurement methods, but with less sensitivity to vibrations, the laser beam replaces the plumbline wire, and the results are automatically sampled in the computerised display unit.

Benefits of the Fixturlaser VSP

• Quick set-up: The Fixturlaser VSP set-up time is minimal.
• Ease of use: Values are easily displayed on screen, eliminating errors in reading a micrometer.
• Safety: There are none of the breakage hazards associated with the wire.
• Accuracy: A repeatability test sets the best sampling filter, and the laser detector can resolve to 0.0001”.
• Reducing measurement time and overall downtime: A full set of measurements can be taken in less than four hours with the Fixturlaser VSP versus several days using the wire. This impacts pre-disassembly readings, assembly, and overall downtime, resulting in huge manpower and dollar savings.
• No need to shut down nearby units to achieve measurement accuracy and repeatability: The Fixturlaser VSP is not affected by vibrations from other mechanical sources.
• Additional measurement applications that can be addressed with the Fixturlaser VSP include: Straightness, Flatness, Pole setting, Roundness of Rotor and Stator, Line Bores.
