Rotor dynamic balance test for hydroelectric unit
摘要
Abstract
Vibrations of hydroelectric unit are often caused by unbalance of rotor weight,and to a unit at its starting test stage,dynamic balance test is an important work.This paper demonstrates the method and key technology of such test,and through finite element dynamic analysis on the rotor,analyzes the balance influence that is caused by an added weight on different planes of the rotor.Then a balance weight plan is proposed for different speeds and different dimension features of the rotor.A dynamic balance test was carried out on the unit 2 of YAVUZ hydropower station in Turkey.In this test,the phase of unbalance weight was exactly detected and confirmed,and the vibration and swing problem of the unit was solved by adding balance weight to the rotor.关键词
