Reed Resonance Problems of Large Vertical Pumps

대형 수직펌프의 리드공진 문제

A detailed investigation of a reed resonance for a vertical pump design has been conducted. The structural features of this class of pump lead to typical dynamic characteristics. Of particular importance is the fact that the pump assembly is suspended on a high column above the floor with a heavy motor on the top. Considerable amount of mass forces is involved and the vibration can cause damage to the pumps or to the foundation. It is shown that the reed resonance of the pump-motor system plays important role for design and troubleshooting purposes.
