How Vibration Analysis Prevented a Catastrophic Failure
In a recent vibration analysis of a paper machine’s drying cylinder, we identified a 22238 C4 bearing on the drive side in an advanced stage of wear. In the first month of data collection, the overall acceleration level was already at 1.9 Gs, rising to 3.78 Gs the following month. Based on this data, we recommended an intervention during the next scheduled shutdown.

Steam Turbine Governor Valve Failure: A Case Study from Singapore Refining Company
At the Asia Turbomachinery & Pump Symposium 2018, Vasanth Bhat and Thangavel Suthan from Singapore Refining Company (SRC) presented a compelling case study on the failure of a steam turbine governor valve in their Wet Gas Compressor (WGC) unit. This critical asset, driven by a four-stage back pressure turbine, experienced two major failures in the main valve stem of the steam inlet valve, leading to significant operational challenges.

What Is the Difference Between “Vibration Isolators” and “Shock Absorbers”?
This article will discuss vibration isolators, which are applied in many situations to achieve vibration isolation. This brings us back to a common question: is a vibration isolator the same as a shock isolator or a shock absorber? It also explores whether the purpose of vibration isolation is best described as a combination of isolation and shock absorption, or as vibration isolation and general isolation.

Mounting a Triaxial MEMS Accelerometer
When many people think of a MEMS accelerometer, they think of a MEMS chip. This 2-minute tip will not address MEMS accelerometer chips, which require a pick-n-place machine and soldering to install onto a circuit board and then connection to an output mechanism. We’re going to address mounting an industrial MEMS triaxial accelerometer sensor to achieve the optimal measurement range and accurate readings.

Crest Factor in Vibration Analysis
The Crest Factor (CF) is a fundamental metric in vibration analysis, defined as the ratio of the peak amplitude of a time waveform to its root mean square (RMS) value This dimensionless ratio serves as an indicator of the severity of transient or impulsive events in a vibration signal.
