Keeping production facilities running at all-time 24 hours a day, 365 days a year avoiding expensive breakdowns improving the reliability of installations, industry is constantly dealing with these issues.
To keep plants operational at all time, many industries have established predictive maintenance programs. One of the most valuable diagnostic tools for any predictive maintenance program is thermal imaging.
Our expertise contain all the features needed for quick and powerful thermal inspections. Electrical cabins and motor control centers can be regularly scanned with the thermal imaging camera. If left unchecked, heat can rise to the point that connections melt and breakdown, as a result fire may break-out.
Beside loose connections, electrical systems can be suffer from load un-balances, corrosion and increase in impedance to current. Thermal inspections can quickly scan hot spots, determine the severity of problem and help establish the time-frame in which the equipment should be repaired.
One of the many advantages of thermal imaging is the ability to performing inspections while electrical systems are under load. Since thermal imaging is a non-contact diagnostic method, a thermographer can quickly scan a particular piece of equipment from a safe distance, leave the hazardous area, return to his office and analyze the data without ever putting himself in danger.
Thermal imaging cameras are perfectly suited for electrical systems. The highly portable economically designed cameras and can be used several hours per day. They can provide high resolution thermal images that will capture temperature differences as small as 0.03 C°. They contain all the necessary features to make well informed decisions. Useful features include touch screen. Scalable picture in picture which makes it easy to locate areas of interest. Thermal fusion which merges visual and thermal images to offer better analysis.
Most thermal images camera are also equipped with meter-link technologies. Meter-link technology simplify the work in electrical inspections and making it possible to transfer by a Bluetooth and data acquired by a clamp-meter and extracted into the thermal imaging camera.
The meter-link technologies saves time and eliminates the risk of erroneous record or notes. The ability to save the both thermal and visual image allow showing the location of the hot-spot to the people who be making the repairs. Also distribution transformers benefit from the use of thermal imaging. Examples of failure in low and middle voltage equipment are high resistance connections, corroded connections, internal fuse damage, internal circuit breaker faults and poor connections and internal damage.
Thermal imaging cameras are also commonly used for electrical high voltage inspections. As electrical connections become loose, there is a resistance to current that can cause increase in temperature. This can cause components to fail resulting in unplanned outages and injuries. In addition, the efficiency of an electrical grid becomes low prior to failure. Thus energy spent generating heat causing un-necessary losses. How a transformer often checked with thermal imaging cameras. Temperatures of the cooling fins and the high voltage connections can be compared if it’s necessary. Corrective action can be taken before the problems occur. Also high voltage power lines can be inspected with the thermal imaging camera.
Other high voltage installation that are checked with the thermal imaging camera include circuit breaker and switches. Potential problem areas will clearly be shown on the thermal image. Examples of failures in high voltage installations are oxidation of high voltage connections, overheated connections, uncorrected secure connections, insulated defects.
In many industries, mechanical systems are the back-bone of the operations. Thermal data can be valuable source of complementary information to the vibration studies in mechanical equipment monitoring. Mechanical systems will heat up if there is a misalignment in some point of the system. Thanks to features such as line profiles, you will immediately see if there is a problem.
Conveyor belts are another examples of moving parts. If a roller is worn out, it will clearly show in a thermal image so that it can be replaced. Typically when mechanical equipment become worn and less efficient, the heat emitted will increase. Consequently, the temperature of faulty equipment will increase rapidly before failure.
Motors are also widely inspected with thermal imaging cameras. Motors could be observed for brushed contacts where an armature both of which typically produce excessive heat but not necessarily vibration prior to failure. Thermal imaging gives a full overview of different motors where necessary further examination of overheated motors could be done.
Most thermal imaging cameras are equipped with laser pointer which eliminates the tendency to finger-point in dangerous areas. Examples of faults that could extracted with thermal image are overheated motors, suspect rollers, overloaded pumps, hot bearings, overheated windings.
Thermal imaging also gives valuable information about the condition of the pipe, tube and valve insulation. A thermal imaging camera can quickly give an overview of entire installation, thus no need to check each and every pipe individually. Thanks to analysis tools like spot-meters, line profiles, areas, iso-therms and many more. Potential problem areas can be identified and repairs can be done before real and sometimes dangerous problem occur.
Thermal imaging cameras are also used to inspect ovens installations. They are also used in the petro-chemical sector. They provide rapid, accurate diagnosis for furnace maintenance, refractory loss management, heat exchangers for blocked pipes.
Thermal imaging cameras are also widely used for cracker installations. Many pipes, tubes and cracker are insulated with heat resistant refractory stone. Thermal imaging can easily see if the insulation is still intact or not.
Steam traps are also subjected to thermal inspections. Potential problems can clearly show up in the thermal image. Other examples are insulation breakdowns, hotspots in ovens, refractory insulation defects, and damaged insulation and break down of refractory in rotary cement kilns.
During certain production processes, gas is a generator which burned off in flares. The flames generated can be invisible to the human eye. It’s important to show that the flare is burning. Otherwise harmful gases might enter the atmosphere. Thermal imaging can easily be see if the flare is burning or not.
Thermal imaging can also easily be used for tank level detection. Thanks to emissivity effects or the temperature differences, the thermal image clearly shows the level of the liquid. Thermal imaging can also easily be used to see if all barrels in the production process are properly filled. Thermal imaging is used in numerous industries. Other applications include finding hotspots in welding robots, inspection of aeronautical materials, mold inspection, checking temperature distribution in pavements, inspection in paper-mills.
