Coppus RLV-22L Steam Turbine Runs Clean With Isomag Bearing Isolators

Water contamination in bearing oil is a common recurring issue for steam turbines in the oil and gas industry. Labyrinth isolators fail to stop condensate from entering the bearing housing as steam dissipates from the carbon box. A Revak repair facility has a customer with many steam turbines in operation, and a common maintenance procedure is to drain the water out of the bearing housings. After a failure on their Coppus RLV-22L steam turbine, Revak specified Isomag bearing isolators.

Revak put an end to this issue for their customer by replacing the existing labyrinth isolators with Isomag bearing isolators. Since installed in 2006, the end user reports that the seals are running smoothly at low temperatures with no evidence of water contamination. The old practice of evaporating water out of the oil twice a year is no longer necessary.
