Where can leakages occur?
The uncanny leaks are the most occurring maintenance issues that can appear in any part of the system. Such kinds of leaks require proper detection of the location of the leak and a repair.
Although leakage can occur in any part of the system, generally, the most common problem areas are:
Fittings, tubes, hoses, and coupling: Push-to-lock and tubes are among various typical problems.
Open condensate traps: Improperly operating dirty seals and solenoids are often major problem areas.
Regulators, lubricators, and filters: Improper installation can also cause such leakage.
Disconnects: Maybe O-rings are missing to complete the sealing.
Shut-off and control valves: Worn packing of the stem can also cause leakage.
Point of use devices: Poorly maintained or old tools can have several internal leaks.
Thread sealants: Improperly applied or incorrect thread sealants can result in leaks.
Flanges: Missing welds are among a common problem.
Consider using the highest quality materials besides applying them according to the instructions.
- Pipe joints: If welds are missing, they can also trigger this kind of leakage.
- Cylinder rod packing: If packing materials are worn out, they can cause leakage.
Why ultrasonic detectors for leakage detection?
Since air leakages are nearly invisible, so we devise other ways to see them. The best method to find leakages is using an ultrasonic leakage detector, which can sense the high-frequency sounds of the compressed air leakages. These portable devices include directional microphones, audio filters, and amplifiers, and most have either earphones or visual indicators to detect the leakages.
Ultrasonic leakage detection is nowadays the most predominant form of leakage detection. Due to its efficient built-up, it adapts to several leakage detection situations. The principle of this leak detection is more than superficial. The leak moves from a high-pressure laminar flow towards low-pressure turbulence in a vacuum or pressure leak. This disturbance causes a noise that usually has inaudible frequencies; hence the human ears cannot detect them. The ultrasonic leakage detector converts these inaudible noise signals to audible ones while ignoring the loud background noise with the help of audio filters. So, you can hear leakages with the use of wireless headsets even at the noisiest places.
The benefits of ultrasonic leak detection include speed, versatility, and ease of use. Moreover, it provides the ability to find a wide variety of leakages, to perform tests while equipment is running. They need a minimum of training, and operators mostly become competent after only 15 minutes of activity.
Because of the nature of ultrasound, it is directional in transmission. Due to this reason, signals are loudest near the source. By scanning the test area, it is straightforward to pinpoint the exact location. Hence, it is a very accurate and fast process.
