How to detect gas leakage in pressure pipeline?
In the production process, in order to effectively control the leakage, it is necessary to find the leak in time, and accurately judge and determine the specific location of the leak, and find out the leakage point. For invisible, inaudible, intangible, intangible, or flammable and explosive dangerous places with flammable and explosive media, it is necessary to use instruments and equipment for leakage detection, and use special instruments to detect leaks in the case of ensuring the safety of personnel, and help enterprises find potential safety hazards in a timely manner.
Pipeline leakage can be divided into large leakage, medium leakage and small leakage according to the different leakage volume, using our ultrasonic leak detector, 0006MPa pressure, 0Leaks from 05mm diameter small holes, whether it is large, medium or small, our ultrasonic leak detector can detect the leaks without stopping production and normal operation of the factory.
The working principle of the ultrasonic leak detector is to detect small gas leaks through the capture, amplification, detection and decoding of ultrasonic waves, and convert the leakage phenomenon into sound signals that can be heard by the human ear, and at the same time display the leakage value on the instrument screen.
A method for detecting gas leakage in pipelines using the Northern Control Power Ultrasonic Leak Detector.
1. Insert the swan neck sensor into the 7-pin aviation plug on the main unit.
2. Press the "Power On" button.
3. Move the detection probe to the area to be detected, and detect sequentially. When the instrument is heard coming out of the headphones
's audio signal increases rapidly, while the display test value becomes larger, indicating that a leak has been detected.
4. Insert the sound focus probe into the front end of the swan neck sensor to accurately locate the leakage point, and the probe is connected step by step
Near the leakage area, when the sound is louder and the instrument display shows the maximum value, the position of the probe is pointed
Leak point. 5. During the detection, you can press the "+" button to adjust the gain (sensitivity) to meet the detection needs.
