USING THERMAL IMAGING TO HELP SOLVE MACHINERY PROBLEMS
Thermography can be used to identify and analyse thermal anomalies for the purposes of condition monitoring of machines. These thermal anomalies are usually caused by such mechanisms as operation, improper lubrication, misalignment, worn components, or mechanical loading anomalies for example.Infrared thermography is based on measuring the distribution of radiant thermal energy (heat) emitted from a target surface, and converting this to a surface temperature map or thermogram. Thermal energy is present with the operation of all machines. It can be in the form of: friction losses within machines; energy losses within machines; as a characteristic of the process media; or, any combination thereof. As a result, temperature can be a key parameter for monitoring the performance of machines, the condition of machines, and the diagnostics of machine problems. Temperature is also one of the key causes, and symptoms, of lubricant degradation and loss of lubrication function within a machine and as such thermal imaging is a very useful tool for solving such problems.Infrared thermography is an ideal technology to investigate thermal anomalies on machines because it provides complete thermal images of a machine, or a machine component, with no physical attachments (non-intrusive), requires little set-up, and provides the results in a very short period of time. As such thermography techniques can be used as part of a condition monitoring process when such a process is implemented in accordance with ISO 17359.
