Application knowledge of acoustic leak detector

Application of acoustic leak detector using a leak detector can effectively detect the location of leakage The effectiveness is determined by the primary (red) color thermal resistance light and the secondary (blue) color light Leakage detectors are widely used in petrochemical industry, electric power industry, aviation and shipbuilding industry, paper industry, textile industry, metallurgical industry, etc. Pressure/vacuum leakage when any gas (air, oxygen, nitrogen, etc.) passes through a leakage hole, it will produce a turbulence with detectable high-frequency components. Use the leakage detector to scan the nearby area, and you can hear the torrent sound or indication of leakage through the headset. The closer the detector is to the leakage point, the louder the torrent sound will be and the higher the indication reading value will be. Of course, environmental noise is a problem, but the use of rubber sound gathering probe can reduce the receiving area of the detector. In order to block the interference of noise waves, the frequency adjustment function of Tibetan mastiff leakage detector can reduce the current low background noise interference, so that inexperienced users can also easily operate to detect leakage. Application of ultrasonic leakage detector: find out the leakage points of gas, natural gas pipeline/barrel tank, laboratory/hospital operating room, air conditioner, air pressure pipeline, gas supply/nitrogen system, oil tank truck and any other gas pipeline/compartment/barrel tank. The leakage of heat exchanger, boiler and condenser, true air or pressure leakage can be detected by leakage detector cargo-safe, and the accessories, valves and coupling shafts can be scanned for leakage. The high-frequency and short wave characteristics of ultrasonic wave enable users to locate the leakage position under the condition of greatly improving the reliability of high-noise ring

the condensation pipe and heat exchange pipe can be tested by the following three methods: vacuum, pressure and ultrasonic sound. Application: find leakage points of heat exchangers, boilers and condensers in petrochemical plants, heavy industries, power plants, laboratories, and general surface tensiometer plants. Valve leakage valves can be accurately detected when problems such as leakage or blockage occur. For valves with leakage, when the medium flows from the high-pressure side through the leakage point to the low-pressure side, it will produce turbulence, while good valves are relatively quiet. Because the leakage detector cargo-safe has a wide sensitivity and ultrasonic frequency selection range, even in a noisy environment, all types of valves can accurately detect leakage problems. Model of bearing monitoring leakage detector: cargo-safe can detect bearing faults in the initial stage. NASA research center has confirmed that ultrasonic bearing monitoring can locate potential bearing faults earlier than using traditional temperature and vibration testing methods. Model of interface tension meter leakage detector: take cargo-sa automobile maintenance Fe as an example, the user can hear the sound quality and observe the reading value of the meter. Therefore, trend monitoring, maintenance and identification of potential bearing problems are provided, and the bandwidth adjustment function makes it easier to isolate and analyze a bearing. Arc light or partial discharge (Corona) will generate ultrasonic signals from the position of insulation deterioration. This discharge signal can quickly locate the fault point by scanning the area with the leakage detector cargo-safe. This kind of signal sounds like a frying sound or buzzing sound with headphones. The closer the detector is to the discharge, the stronger the signal will be obtained. It is applicable to the prevention of automobile maintenance and insulation devices of power switches, transformers, relays, circuit breakers, bus bars, etc. the construction of new energy vehicles is promoted to use the national monitoring platform for maintenance and repair. Application: electric arc, partial discharge or leakage trace, detection and positioning of power plants, factory substations, high-voltage distribution boxes, high-voltage iron towers, transformers, high-voltage insulation detection. Detecting arc light or partial discharge (electric quantity) of electrical equipment will generate ultrasonic signal from the position of insulation deterioration. This discharge signal can quickly locate the fault point by scanning the area with leakage detector cargo-safe. This kind of signal sounds like a deep fried car supplies with a loud or buzzing sound with headphones. The closer the detector is to the discharge, the stronger the signal will be obtained. It is suitable for the preventive maintenance and repair of power switches, transformers, relays, busbar boards, insulation devices, etc. Application: power plant, 3. Check and set or input data directly from the pull-down menu. Arc, partial discharge or leakage traces, detection and positioning of factory substation and high-voltage distribution box, high-voltage Automobile decorative pressure iron tower, transformer, high-voltage insulation detection

ultrasonic sealing test ultrasonic sound (leakage detector cargo-safe) sealing test is a non-destructive off-line test method, which does not need to be pressurized, so it is faster, simpler and more accurate than the traditional method using pressurized or foam. This test method is to place the ultrasonic sound source generator inside or at one end without pressurization in the test sealing chamber/simple groove, and the ultrasonic signal will flow to all corners of the object to be tested and penetrate any leakage position. Therefore, the leakage detector cargo-safe scans the penetrating car externally and refits the ultrasonic signal to indicate the leakage position. Applications: aircraft doors and windows, fuel tanks, cockpit leakage, cabin/submarine cabin leakage, car door and window leakage
