수위변화에 따른 수직형 펌프의 진동 발생 사례 고찰
A Case Study on Vibration of Vertical Pumps according to Changing Water Level
- 발행 : 2012.04.26
초록
Vertical pumps are structurally weak in terms of vibration because of installed heavy motor on top of the pumps in form of cantilever. So high vibration on top of the pumps can occur with low vibration in the bottom. These vibration problems experienced very frequently. Majority of studies have been related to the unbalance of rotating parts or structural resonance. In this paper, we introduce an unusual case, vibration variation caused by VPF(Vane Passing Frequency) according to water level.
