Description

Ultrasonic detector for pressure pipeline

Technical Field

Background

Acoustic waves are a form of propagation of the mechanical vibration state of an object. Vibration refers to the reciprocal movement of a mass point of a substance near its equilibrium position. Beyond the upper limit of the human ear hearing, people call such inaudible sound waves ultrasonic waves. The ultrasonic wave is generally transmitted in an elastic medium in a longitudinal wave mode, and is characterized by high ultrasonic frequency and short wavelength, has good beam-shooting property and directivity along a straight line in a certain distance, and if a container or a pipeline is filled with gas, when the internal pressure is higher than the external pressure, the gas can be flushed out from a leak hole once the container is provided with the leak hole due to the fact that the internal pressure and the external pressure are higher. When the size of the leak hole is small and the Reynolds number is high, the gas rushes out to form turbulence, the turbulence generates sound waves with a certain frequency near the leak hole, the frequency of the sound wave vibration is related to the size of the leak hole, when the leak hole is large, the leakage sound can be heard by human ears, and the leakage sound can not be heard by human ears, but can propagate in the air, and the leakage sound is called idle ultrasonic wave. Ultrasonic waves are high-frequency short-wave signals whose intensity decays rapidly with increasing propagation distance. The ultrasonic wave has directivity. With this feature, the correct leak position can be determined.
