The pressure of medium is changed alternately in the propagation process of rod transducer. In positive pressure region, the liquid medium bears extrusion force and forms increased density, conversely, in the negative pressure region, the lquid medium bears tear force and forms reduced density. The ultrasonic energy is distributed at 360° along the whole length of rod body. The output energy will not be affected by the change of the load such as the liquid level, temperature difference, etc. Compared to the traditional ultrasonic box, it has mor extensive range of applications and longer service life. Ultrasonic processing is a mature and widely-applied technology in cleaning, extraction, chemical reaction, anti scale, water treatment and so on.
