Infrared Condition Monitoring
A breakdown of mechanical and rotating equipment in a production facility can cost time and money. Some examples of rotating and mechanical equipment where thermography is used: conveyors, motors, motor bearings, refractory, couplings, belts, valves, gear boxes and tank levels.
How Mechanical IR Inspections Work
Infrared inspection is nondestructive and non-contact and typically can performed under normal operations which does not require plant shutdowns.
High temperatures in mechanical equipment can indicate excessive friction, worn components, lubrication breakdown or other common problems that can lead to approaching failures.
Overheating in motors is typically a result of imbalance or misalignment. It can also be due to high electrical resistance and other friction. It is best to take readings of motors over time or comparing similar motors under similar loads.
Equipment such as conveyors can be easily inspected as long as a clear line of sight is available. If bearings and rollers fail in can shut down and entire process. When the friction increases inside a bearing then the bearing will begin to overheat. This can be caused by over or under lubrication, normal wear or misalignment.
Thermal images of motor bearings and couplings can also be inspected in a similar fashion.
See our page on electrical system scans also.
Typically mechanical equipment will fail gradually over time. For example motors and bearings will all exhibit a rise in temperature as a they begins to fail. Most thermal inspections for mechanical equipment is not absolute temperature but observing thermal patterns and comparing similar equipment under similar load.
