Energy Savings by Maintaining Fan Vibrations within Specs
In industrial environment, it is a common observation that the equipment picks-up dirt, grime, grease and other particulate matter. This is more so with the air handling equipment associated with processes such as paint booths and ovens, dust collectors, stamping and welding operations, etc. As the blades of these fans get dirty, they start generating vibration of the entire fan system. Lack of scheduled cleaning can result in excessive vibrations and eventual fatigue failure of the equipment. Though, it is not a common knowledge that continuous vibration of equipment also comes at cost of excessive electricity consumption!
At an automotive paint facility, we observed excessive vibrations on the fans associated with spraybooths. We added real-time vibration monitoring equipment on the spraybooth exhaust fans, as a tool for preventive and predictive maintenance. Data was monitored by the Human Machine Interface (HMI) with real-time and historical trending of vibrations as a tool to schedule cleaning of fans. Along with vibrations, we also monitored energy consumption by the fan motor.
