摘要

A rotordynamics test stand, equipped with an active magnetic bearing unit, was developed for measuring fluid reaction forces generating on annular pressure seals and herrings of pumps. The active magnetic herring unit enables control of eccentricity and the whirl radius of rotor towards the center of a test piece. This advantageous characteristic made it possible to make precise estimations on fluid reaction forces under various parameters. The following introduces examples of estimations on fluid dynamics and seal dynamics around impellers under fault conditions, a feat considered difficult to achieve by rotordynamic analysis. The importance of studying properties under different temperature, pressure, and eccentricity versus turbomachinery design is discussed as well.
