Spray tube ultrasonic washing apparatus

摘要: Disclosed is a spray type ultrasonic washing apparatus using coaxial nozzle structure which composed of inner and outer hollow frustums for supplying deaerated liquid in the annular passage delimited by nondeaerated frustum, thus permitting to be enclosed spraying against work washed, thereby isolating from surrounding atmosphere prevent invasion air into liquid. Thus, cavitation can formed effectively liquid, performed at an increased efficiency.
