Online, real-time vibration monitoring equipment can detect problems caused by bearing damage, shaft imbalance, and other related issues. Focused, early damage detection through vibration analysis can provide sufficient time for ordering new parts and scheduling maintenance, thus preventing costly unscheduled shutdowns.
Vibration monitoring equipment can diagnose the most common mechanical problems of unbalance, looseness, misalignment, and bearing failures in various mechanical equipment, such as motors, fans, blowers, belts, chain drives gearboxes, couplings, pumps, compressors, closed coupled machines, and spindles.
An online monitor can provide advanced predictive diagnostics, integration to process control, and 'trip advisory' for critical equipment. As against machinery protection, Trip Advisory is optimized for case-mounted sensors on rolling-element bearing machines that employ vibration processing software and instantaneous spike filtering. This combination of techniques reduces false trips. It is usually implemented at the alarm notification level but is also used as a hard-wired automatic trip.
Raw signals are provided to an intelligent device located nearby through permanently mounted sensors. Data is routed from the field device and stored at a server. Before sending exceptions to the user, the intelligent field device uses processing techniques, such as waveform and spectral analysis. Diagnostic rules are then applied to determine abnormal situations' probable cause and severity.
Integrated online Vibration Sensors for Motorsare focused on critical equipment whose failure would shut down an entire process or plant. However, since only about five percent of the machines in most plants can bring production to a halt, this technology is now being installed on essential pumping systems where a failure might reduce output by half or more and is capable of causingsignificant machine damage.
A decision-maker is greatly empowered to improve machinery health and reliability by integrating monitoring systems with the plant's process automation system. If the diagnostics show that immediate repairs are necessary, action can be taken quickly to prevent damage. Depending upon the diagnosis, it may be possible to delay maintenance until the next scheduled outage. Using online Vibration Sensors For Pumps, Vibration analysis can predict what will happen to a machine shortly. This makes the difference between saving a machine by tripping it and keeping a production schedule by waiting for the best time to shut down.
