Flow Induced Vibration - Pipelines, Piping and Fluid

A concern has been expressed about vibration of the nozzle due to the high velocity flow through the nozzle. No specific basis is given. Now, I'm aware of flow induced vibration on a projection, such as a thermowell, due to flow in the main header/duct. ...<< more>>

Pump vibration – Mc Nally Institute

Pump vibration. Centrifugal pump vibration readings 2-9. Pipe strain. Either by design or as a result of thermal growth. If bearings are your primary concern high and low electronic filters can be used in some equipment to filter out frequencies below 55 Hz. and above 2500 Hz. These filters will help the operator zero in on those ...<< more>>

Designing Equipment to Avoid Pump Cavitation

Excessively high pump rpm and pressure. Pipe blockages. Poor design of the piping system. Poor pump suction. Discharge Cavitation. Discharge cavitation, on the other hand, occurs when the pressure at the discharge end of the pump is excessively high. Pump cavitation, although easily identified by its excessive noise and vibration, is a ...<< more>>
