超声检测装置是在6根输送乳胶的管道壁上每一根活流体运动方向布放四对超声换能器, 在每对一发一收的换能器间流动的乳胶中形成稳态声场。当有气泡经过便可检测到声场所受 到的扰动。四对换能器在角度上分布是复盖整个管道横截面而不致遗漏流经的气泡,在沿管 道流向上分布可以?
The ultrasonic testing device is to place four pairs of ultrasonic transducers in the direction of the movement of each live fluid on the wall of the six delivery latexes to form a steady state sound field in the latex flowing between each pair of transducers. When there is a bubble can be detected by the sound field disturbance. Four pairs of transducers are angularly distributed across the entire pipe cross-section without leakage of the air bubbles, and can be distributed along the pipe flow?
