Due to the unique design characteristics of the round tube, the ultrasonic vibrator is especially suitable for cleaning all kinds of pipelines, the principle is to convert electrical energy into ultrasonic energy, and according to its own law to transfer to the scale, water, the inner wall of the pipeline, so that it can obtain a lot of energy. The shock wave generated by ultrasonic wave in the transmission process causes the scale, water and inner wall of the pipeline to resonate. Due to the different vibration frequencies of the scale, water and inner wall of the pipeline, the water molecules in the pipeline have a fierce collision, resulting in a strong impact force, impacting the scale layer on the heat exchange surface, making it brittle, stripped, dropped and crushed, and discharged with the sewage of the equipment. Thus, the ultrasonic vibrator can completely clean the inner wall of the pipeline. In addition, the ultrasonic vibrator can also be used for the cleaning of the tank, can be freely placed in any position of the cleaning tank, the use of very flexible and convenient, and the volume space occupied is very small, and the cleaning does not leave dead corners.
