The working principle of the ultrasonic bottle washing machine, the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and transmitted to the medium-the cleaning solvent, and the ultrasonic wave moves forward in the cleaning solution. Radiation makes the liquid flow and produces tens of thousands of tiny bubbles.
These bubbles form and grow in the negative pressure zone where the ultrasonic wave propagates longitudinally, and quickly close in the positive pressure zone. In this process known as "cavitation" effect, the closure of bubbles can form an instantaneous high pressure of more than 1000 air pressures. The continuous generation of instantaneous high pressure is like a series of small "explosions" continuously impacting the surface of the object, causing the object to be damaged. The dirt on the surface and crevices quickly peels off, so as to achieve the purpose of surface purification of the object. In the middle is a layer of stainless steel plate of a certain thickness. The transducer head is attached under this layer of steel plate. The AC signal of a certain frequency and voltage is generated by the ultrasonic generator to drive the transducer head and the stainless steel plate to perform high-frequency vibration together. When the steel plate vibrates upwards, push the water upwards. When the steel plate vibrates downwards, the water cannot keep up with the vibration speed of the steel plate. A gap will be formed between the water and the steel plate. In this way, repeated vibrations will cause many bubbles to form, such as As shown in the picture: this kind of bubble is produced by the "cavitation effect", we call it cavitation bubble. Cavitation bubbles propagate into the water along the direction of vibration. If there is a workpiece in the water, the cavitation bubble hits the surface of the workpiece and generates an impact force of thousands of atmospheres, which drives the dirt on the surface of the workpiece to fall off.
