Balancing a rotor using Vibxpert II – video

Rotor balancing video Rotor balancing video from Pruftechnik using Vibxpert II. This short video walks you step by step through a simple rotor balancing procedure. Unbalance is a major root cause of machinery failure. Unbalance forces on bearings and seals can drastically reduce their useful lifetime. In fact, an increase in load of 20% can…

How a gas turbine works

How a gas turbine works This short video describes how a gas turbine works Thanks to GE for creating this video which also explains a combined cycle power plant. Air is compressed in the turbine compressor stage, causing it to heat up. Gas is added to the mix which combusts and causes the turbine blades…

Rotor unbalance

Rotor Unbalance Rotor unbalance causes premature damage to  bearings and seals and greatly reduces the mean time between failures (MTBF) of machines. The vibration from rotor unbalance can cause false brinelling in standby machines and can reduce product quality. Vibration analysis can be used to detect rotor unbalance (or imbalance if you prefer) and most…

Orbit plots and centerline diagrams an introduction

Orbit plots and centerline diagrams are used when analyzing vibration in journal bearings using data from proximity probes. The centerline plot shows where the shaft is located in the bearing. It can be used to see if there is misalignment or excessive preload. The centerline diagram can also be used to detect wear in the…

Vibration monitoring of gearboxes

Vibration analysis in gearboxes can detect common defects such as gear misalignment, broken gear teeth, backlash and wear. Ferrography or wear particle analysis is also especially useful for detecting gearbox defects at an early stage. The benefit of both vibration analysis and wear particle analysis is to detect defects in gearboxes early in order to…

Detecting bearing defects using vibration analysis – video

Detecting bearing defects using vibration analysis Alan Friedman describes the detection of bearing defects using vibration analysis from the time waveform, the vibration spectrum and amplitude demodulation.  This video is appropriate for anyone interested in machinery vibration analysis who wants to know about detecting bearing defects using vibration analysis. Bearing defects generate pulsations each time…
