Vibration Problems Of Large Vertical Pumps And Motors
Abstract
A large vertical pump with its associated motor driver constitutes a very complex dynamic system. The apparent simplicity of the visible cantilever portion of the machine belies the complex interaction of the unit with its piping, foundation, soil and process fluid, all of which must be considered in order to achieve a successful design. This system approach is presented in this paper by an analytical and experimental study of a 3000 hp crude oil loading pump. The study shows the large number of possible vibrational modes which can exist near the operational speed of a typical system and the factors which should be considered in predicting resonant frequencies. Also included in the paper are several case histories which illustrate some of the dynamic problems which are common to vertical machines.
