How will aerial drone thermography help me in my day to day asset maintenance and how does a thermal inspection process work.
There is no set definition for thermography if you do a quick search on google you will be inundated with numerous answers that often contradict each other. However, in laymen’s terms, the process of thermal inspection is the acquisition of infrared data that is radiated from anything that has a base temperature of above zero degrees Kelvin equated to (-273.15 degrees C) So anything and everything.
In a previous career, we often carried out reactive maintenance using thermal imaging equipment to detect excessive component slippage across a range of actuators in a hydraulic circuit, which would generally provide us with the data required to assume the level of efficiency in that component. In a reactive situation, it is a quick method of locating a defective component that might be excessively worn allowing excessive energy loss in terms of fluid leakage across the seat of its sealing face. This creates heat which might not be detected using standard methods of fault finding. In a preventive situation, you might be using thermal data to formulate trend analysis allowing early detection of defective components. Generally, in rotating equipment, excessive energy losses equate to component deterioration such as bearings or sealing faces.
This same principle is observed in any industry, excessive energy losses or uneven energy losses generate a heat signature which could have the potential to have a detrimental effect on other components associated with that system. For instance, if a bearing is emitting a greater heat signature than usual and it is overlooked. Eventually, there will be a catastrophic failure resulting in excessive downtime or NPT.
The science of thermography has paid dividends towards many industries in numerous ways depicting various degrees of component failure. Building Envelope Inspection is another popular method for thermal cameras and allows the end user to evaluate the amount of energy loss through the envelope due to lack of proper insulation. A thermal camera can pick up hot spots during building envelope inspections and provide the client with vital information allowing pinpoint accuracy of insulation breakdown.
Aerial Thermal Inspection Using Drone Technology.
Traditional methods of thermal inspection, especially building envelope inspection is carried out using scaffold or other access methods and is generally a long invasive process and to a degree carries a potential risk to the general public in terms of drops from height. DJM Aerial Solutions are now capable of carrying out your building envelope inspection or general thermography work using this disruptive innovation. Our survey grade drone technology can not only provide you with a none invasive cheaper alternative but also allows the end user to easily decipher the data provided as we now have the capability to provide RGB and Thermal images of the same area sequentially. Allowing your building engineers to easily identify any problems.
There are various options to thermography which do not solely relate to building envelope inspection, for instance, site work and structuring thermal survey into your preventive maintenance routines is essential and provides the end user with the analytical tools to make better-informed decisions on the degradation of your assets.
DJM Aerial Solutions are well equipped with not only high specification drone technology but also the engineering skills and capabilities to provide you with the essential none invasive inspection routines needed for today’s competitive market.
