Abstract
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.
Claims4
For rotary equipment (a) having a given natural frequency, and (b) being mounted to a limbed pedestal, said pedestal bearing an equipment driver, and having a differing natural frequency, means for changing one of said frequencies to match the other of said frequencies, comprising:
- means for coupling said rotary equipment to limbs of said pedestal;
- wherein
- said coupling means comprises means for creating a selective mechanical stress between said limbs and said equipment;
- said stress creating means comprises a bracket for attachment to one of said limbs;
- said bracket has a bearing surface formed thereon;
- and
- means, for interpositioning between said equipment and said bearing surface, for biasingly constraining said bearing surface away from said equipment.
