Mechanism Investigation and Measures on Acoustic Vibration Phenomena of Water Supply Piping
급수 배관계의 음향진동 현상 고찰 및 대책
- Published : 2012.10.27
Abstract
The downstream piping system of the water supply system in a supercritical power plant is affected by the fluctuation pressure waves induced by accessing to the acoustic modes of the piping systems with the rotation and impeller passing pulsations of the feed water pump. There are the phenomena amplified at the same time in the range of 415 ~ 455Hz, 830 ~ 910Hz, 1245 ~ 1365Hz and 1660 ~ 1820Hz on the spectrums of the vibration, the sound pressure, and the pressure fluctuation waves.
