Dynamic Improvement Of An Overhung Single-Stage Pump
MetadataShow full item record
Vibration control is an important aspect of all pump design. It helps assure quiet operation and high reliability. Therefore, the design of pump components should avoid any dangerous resonances with excitation forces, such as unbalance, misalignment, vane passing frequencies, etc. A key pump component is the bearing housing, since this transmits forces from the shaft to the pump casing and therefore to foundations. Bearing housing designs having good dynamic behavior can reduce vibration levels and dramatically improve both the reliability and life of the whole pump assembly.
