Critical speed (nk) 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, fi) 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 rotational

the machine, and above this speed, the capacity varies in- versely with the speed. The transition at which this occurs is defined (Rose and English, 1967) as the critical speed (NF), and it is obvious that the maximum capacity of a machine w~ll be at the critical speed. At the critical speed (Nc,, DT/[G-(S+T)] = 450 g/N2, (7) Eqs.
