The paper dwells upon new approaches towards imbalance diagnostics for both – separate rotors and shaft rotors. The methods are based on comprehensive usage of sensors for absolute support displacement and relative/absolute shaft displacement.
There are a lot of tasks to be solved with such sensors’ application, but the main one is the diagnostics of imbalance and its spreading area. The present paper covers only that one task.
Along with minimizing the absolute radial vibrations of journals and supports, it is also suggested to minimize turning angles of journals and consequently decrease the residual rotor vibration. The method can be utilized witht the COMPACS® system and intended for morden systems of imbalance monitroing and diagnostics and its automatic detection.
