The purpose of this study is to analysis the problems of vibration in power equipment. The occurrence of vibrations represents a serious problem in operation and in the design of nuclear power plant units. However it is quite impossible to eliminate vibrations completely. This is due to the fact that there are many factors that contribute to its appearance. One of the major components that are mostly affected by vibrations is Pipeline .In a nuclear power plants they are one of the most extensive and important elements. Alternative forces caused by Vortex shedding have a severe impact on piping vibrations. The coincidence of pressure pulsations with structural frequency also causes piping vibrations. This study has shown a relation between Strouhal number and Reynolds number which are the most influencing parameters in case of thermodynamically vibration analysis. The other major purpose of this study is to have an enormous discussions in order for reducing unbalanced forces and vibrations. Changing the piping structural frequency or pump helps to eliminate pressure pulsations. Pulsation damper or suction stabilizer have an effect on piping acoustical properties.

Ключевые слова: Pressure pulsations etc., Suction stabilizer, Pulsation damper, Unbalanced forces, Reynolds number, Srouuhal number, Alternative forces, Vortex Shedding
