Critical Speed  Ksb

Critical Speed Ksb

Critical speed (n k) is the rotational speed at which acting dynamic forces cause a machine component (e. g. shaft, rotor) to vibrate at its natural frequency (also referred to as intrinsic frequency, f i) and can even result in resonant vibrations throughout the entire machine and pump set.This effect has the potential to damage fast rotating machinery but can be minimised when such
