Thermal Imaging for Mechanical Applications
By using infrared cameras, we can see the friction that is produced in a mechanical system. In the case of electric motors we can identify bearing problems quickly and easily as the bearings generate more heat as they become pitted, or when they are under-lubricated and sometimes over-lubricated. Electric motors also produce heat from the load that is put on them. This bakes the insulation inside that motor which will eventually lead to a breakdown in its insulation and cause a short that will essentially burn up the motor. Operating an electric motor at 10 degrees Celsius over its design temperature will cut the life of the motor in half. This means that trending the temperatures on a motor can really benefit a company by studying them in order to make repairs before they break down.
We can also look at steam traps, compressors, and all kinds of valves using infrared cameras. Any rotating machinery or process that generates any friction or heat is a great candidate for an infrared survey. We can even see the misalignment between a pump and a motor as misalignment stresses this configuration and generates heat in both components.
