Balancing an Isogyre pump turbine after general overhaul

In cooperation with Martin Märke we were able to successfully balance one of the last Isogyre pump turbines in operation. With just a few test runs, the machine could be released for all operating states. Thanks to the quick and competent evaluation and implementation of the measurement results, the machine was able to be used again for electricity production faster than planned.

Bearing damage on a 100MVA pump turbine Grimsel 2

On the horizontal pump turbine set, expensive bearing damage suddenly occurred on the pump and turbine bearings, the cause of which could not be clearly assigned. On the one hand, a vibration measurement made it possible to determine that the shaft line was increasingly bent during operation by one-sided rubbing by a brush, which resulted in in-admissibly high bearing loads. On the other hand, the set bearing clearances also turned out to be too small. After making the appropriate adjustments, the machine has been running smoothly ever since.
