16 A. - APPLICATIONS 1. LEAK DETECTION This section will cover airborne leak detection of pressure and vacuum systems. (For information concerned with internal leaks such as in Valves and Steam Traps, refer to the appropriate sections). What produces ultrasound in a leak? When a gas passes through a restricted orifice under pressure, it is going fr[...]

17 particular gas it was designed to sense (e.g., helium). The Ultraprobe can sense any type of gas leak since it detects the ultrasound produced by the turbulence of a leak. Because of its versatility, the Ultraprobe may be utilized in a wide variety of leak detection. Pneumatic systems may be checked, pressurized cables, such as those utilized by[...]

18 1. SHIELDING TECHNIQUES Since ultrasound is a high frequency, short wave signal, it can usually be blocked or "shielded". NOTE: When using any method, be sure to follow your plant's or company's safety guidelines. Some common techniques are: a. Body: place your body between the test area and the competing sounds to act as a b[...]

19 The test is conducted by placing an ultrasonic transmitter, called TONE GENERATOR, inside (or on one side) of the test item. The warble pulse -signal from the TONE GENERATOR will instantly "flood" th e test item and penetrate any existing leak hole. Depending on configuration and material, even thin spots in certain metals can be vibra[...]

20 TRANSFORMERS, SWITCHGEAR AND OTHER ELECTRICAL APPARATUS E. ELECTRIC ARC, CORONA, TRACKING DETECTION There are three basic electrical problems that are detected with the Ultraprobe 9000: Arcing: An arc occurs when electricity is conducted to “ground”. Lightning is a good example. Corona: When voltage on an electrical conductor, such as an ant[...]

21 inspect electrical apparatus at a distance. The UWC 2000 is extremely directional and will locate the exact site of an electrical discharge. Another accessory is the LRM-9- Long Range Module which also increases the detection distance of the Ultraprobe. The basic difference is that the LRM is a one-hand operation but has a slightly wider detecti[...]

22 DETECTING BEARING FAILURE There are two basic procedures of testing for bearing problems: COMPARATIVE AND HISTORICAL. The comparative method involves testing two or more similar bearings and "comparing" potential differences. Historical testing requires monitoring a specific bearing over a period of time to establish its history. By an[...]

23 Lack of Lubrication: To avoid lack of lubrication, note the following: 1. As the lubricant film reduces, the sound le vel will increase. A rise of about 8 dB over baseline accompanied by a uniform rushing sound will indicate lack of lubrication. 2. When lubricating, add just enough to return the reading to base line. 3. Use caution. Some lubrica[...]

24 3. GENERAL MECHANICAL TROUBLE SHOOTING As operating equipment begins to fail due to component wear, breakage or misalignment, ultrasonic shifts occur. The accompanying sound pattern changes can save time and guesswork in diagnosing problems if they are adequately monitored. Therefore, an ultrasonic history of key components can prevent unplanned[...]

25 4. LOCATING FAULTY STEAM TRAPS An ultrasonic test of steam traps is a positive test. The main advantage to ultrasonic testing is that it isolates the area being tested by eliminating confusing background noises. A user can quickly adjust to recognizing differences among various steam traps, of which there are three basic types: mechanical, therm[...]

26 INVERTED BUCKET TRAPS normally fail in the open position because the trap loses its prime. This condition means a complete blow -through, not a partial loss. The trap will no longer operate intermittently. Aside from a continuous rushing sound, another clue for steam blow -through is the sound of the b ucket clanging against the side of the trap[...]

27 5. LOCATING FAULTY VALVES: Utilizing the contact (stethoscope) module in the Ultraprobe, valves can easily be monitored to determine if a valve is operating properly. As a liquid or gas flows through a pipe, there is little or no turbulence generated except at bends or obstacles. In the case of a leaking valve, the escaping liquid or gas will mo[...]

28 ABCD METHOD The ABCD method is recommended to check for the potential of competing ultrasounds downstream that may carry back to the area of inspection and give a false indication of a valve leak. For the ABCD method, 1. Refer to steps 1-5 above. 2. Mark two equidistant points upstream (these will be point A and Point B) and compare them to two [...]

29 To locate the leak area, gradually position the rod until the leak sound is heard at its loudest point. An alternative to this is to use a flat metal disc or coin and drop it on the test area. Touch the disc and listen at 20 kHz. This is useful when testing concrete or asphalt to eliminate scratching sounds caused by slight movements of the stet[...]

30 ULTRASOUND TECHNOLOGY The technology of ultrasound is concerned with sound waves that occur above human perception. The average threshold of human perception is 16,500 Hertz. Al though the highest sounds some humans are capable of hearing is 21,000 Hertz , ultrasound technology is usually concerned with frequencies from 20,000 Hertz and up. Anot[...]
