COMPRESSED AIR LEAK DETECTION
Leaks can be a significant source of wasted energy in a compressed air system, sometimes wasting 20-30% of a compressor’s output.
In addition to being a source of wasted energy, leaks can also contribute to other operating losses.
Since Air Leaks are almost impossible to see, other methods must be used to locate them. The best way to detect leaks is to use an Ultrasonic acoustic detector, which can recognize the high-frequency hissing sounds associated with air leaks. These portable units consist of directional microphones, amplifiers, and audio filters, and usually, have either visual indicators or earphones to detect leaks.
An Ultrasonic detector can find mid-to large-sized leaks. The advantages of ultrasonic leak detection include versatility, speed, ease of use, the ability to perform tests while the equipment is running, and the ability to find a wide variety of leaks.
Since ultrasound is directional in transmission, the signal is loudest at its source. By generally scanning around a test area, it is possible to very quickly locate a leak site and find its location. For this reason, ultrasonic leak detection is not only fast, it is also very accurate.
- Cause a drop in system pressure, which can make air tools function less efficiently, adversely affecting production.
- Shorten the life of almost all supply system equipment (including the compressor package itself) by forcing the equipment to cycle more frequently.
- Cause increased running time, which can also lead to additional maintenance requirements and increased unscheduled downtime can lead to adding unnecessary compressor capacity.
