    摘要: A vertical, centrifugal pump, which is suspended from a pedestal which has the pump-driver/motor set thereupon, is tied to limbs of the pedestal, by an adjustable, threaded rod and bracket. The tying arrangement creates a tension between the pump and the pedestal, resulting in a uniform, common system which has only one natural frequency.
