Rider bands (also known as wear bands) are an important consumable component on horizontal reciprocating compressors based on which operators plan maintenance outage. Although both the rider bands and the piston rings contact the cylinder liner; however, the rider bands are designed to carry the full weight of the piston while the piston rings are designed to provide sealing between the piston and bore, written by Fayyaz Qureshi.

Today’s reliability managers understand the key elements of a sound reliability program—avoiding unexpected failures, outages, safety exposures and costs. They invest time and money into creating asset maintenance strategies but often fail to implement and execute the strategies effectively. There is no process for reliability strategy review and updates, or, even if there is, what’s usually missing is any kind of trigger to start the review process, written by Jason Apps.

This case describes how the remote diagnostic team resolved a vibration related issue on the NAP2 PAC Primary Air Compressor. This case highlights how a suitably instrumented compressor train connected to a diagnostic platform (S1 Evo) provided critical information (data) to the Bently Nevada diagnostic engineers, enabling a thorough into investigation into the vibration related issue, as well as determining the root cause, written by Gary Wright & Sergey Drygin PhD.

Vibration excursion in turbomachinery is troublesome, especially when approaching or exceeding a trip level. Understanding of its root-cause is extremely crucial for taking appropriate actions and resolving the issue. Rubs are certainly among the most common malfunctions that cause vibration excursion. This paper discusses how to diagnose rubs that typically occur in turbomachinery based on vibration data, written byJohn J. Yu, Ph.D.
