Development of maintenance technology for rotation equipments in the Tokai Reprocessing Plant, 2; Equipment diagnosis by using the shock pulse method

Inami, Shinichi; Takeuchi, Kenji 

Rotation equipments such as blowers and pumps play an important role for securing safety at the Tokai Reprocessing Plant. The bearings in the rotation equipments are one of the important machine elements for stable driving. The most important control item for the bearings management is to maintain adequate lubrication any time. Oil slick thickness in the bearings can be quantitatively confirmed by the shock pulse method though it was difficult in the conventional vibration method used to confirm lubrication quantitatively. This method contributes to the leveling of the measurement technique in diagnosing the bearings.
