At present, in some ultrasonic cleaners , the transducers stuck to the bottom or wall of the cleaning tank are too densely distributed, arranged one right next to another. The power intensity input to the transducer reaches 2-3 watts per square centimeter. Such a high intensity, on the one hand, will accelerate the cavitation corrosion on the surface of the stainless steel plate (the surface in contact with the cleaning liquid), shortening its service life. On the other hand, due to the excessively high sound intensity. A large number of large bubbles will be generated near the surface of the steel plate, increasing the loss of sound transmission and weakening the cleaning effect in areas far from the transducer. It is generally advisable to select a power intensity of less than 1.5 watts per square centimeter (calculated based on the area of the steel plate with the transducer attached). If the cleaning tank is deep, in addition to having transducers adhered to the bottom of the tank, it is also necessary to consider adhering transducers to the tank walls, or only adhering them to both sides of the tank body.
