Improving Reliability of rotating machines through Vibration Monitoring System


Many new power plants that have supercritical technology are coming up in India. There are several challenges for maintenance and instrumentation engineers to keep a high uptime. At the
same time, there is a large population of old power plants in the country and there is need to upgrade these with new technology and products, to monitor key machines and plan actions in
advance before they break down.
Twenty years ago, power plants were shut down frequently for maintenance. But now it is imperative to monitor these plants to increase the uptime to 95%. It is essential to monitor these critical machines for increasing their efficiency and reliability. Hence real time vibration monitoring is the key to reduce frequent failures of machinery.
With Shinkawa Electric Company, Japan, Forbes Marshall has an alliance for vibration monitoring systems that provide complete early warning systems for potential problems in turbines and other rotating equipment. Shinkawa products are manufactured in Japan and have applications in process plants such as power, refinery, fertilizer, steel, cement, and paper.

What Causes Vibrations?
There are several reasons for vibration in machines. They can be due to:
• Unbalance of shaft
• Bearing problem
• Cracking of the rings
• Fluid coupling problem
• Shaft misalignment
• Oil whirl and other dynamic instabilities
These problems can gradually become very severe and result in unplanned shut downs. To
avoid this, shutdowns are planned. Time Based Maintenance System (TBM) is called preventive maintenance. One can extend the life of the machines by monitoring these online in a cost
effective way. Vibration Monitoring and Analysis is the easiest way to keep machines healthy and efficient in the long run and increase the overall efficiency of the plant. It reduces the overall
operating cost as well as the down time period. Vibration sensors are used to predict faults in a running machine without dismantling it and give a clear indication of the severity by showing the
amplitude of vibration.
Forbes Marshall vibration monitoring system range offers you the latest technology to maintain plant safety and asset protection, with reduced downtime and avoiding untimely shutdowns. Maintaining the systems with minimum cost and high throughput has always been an area of importance. Online vibration monitoring systems are the need of hour and offer the user indirect payback in the
form of protection of critical machinery and reduced maintenance costs.
Vibration monitoring is essential to keeping rotating equipment running smoothly for years. Our Vibration monitoring system range is an indispensable complement to equipment like pumps, motors, fans, compressors, and turbine supervisory systems. Monitors are available in single channel, four channel or multichannel versions.
