Rotordynamic Developments For High Speed Multistage Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)
At present, the majority factor limiting the designer’s ability to predict the rotordynamic behavior of multistage centrifugal pumps is the availability of accurate input data for the forces acting on the rotor. Recent ...
Solutions To Abrasive Wear-Related Rotordynamic Instability Problems On Prudhoe Bay Injection Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)
Prudhoe Bay produced water injection pumps suffered serious vibration problems and high balance piston leakage a few months after initial startup. Even though initial pump orientation at low water rates was satisfactory, ...
Predicting And Improving The Dynamic Behavior Of Multistage High Performance Pumps
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)
Good rotordynamic behavior, implying sufficient stability margin and low sensitivity to unbalance forces, is mandatory for modern high pressure multistage pumps. Stiffness, damping and mass matrices describing the forces ...
