5. The basic principle of ultrasonic cleaning technology
Using ultrasonic transducers (crystal head) to emit high-frequency ultrasonic waves. 28,000 times (28KHZ crystal head) oscillations are generated per second. The liquid is used as the transmission medium. Since ultrasonic waves are a compressive longitudinal wave, their effect on the medium causes pressure changes in the liquid, resulting in countless tiny air bubbles. This causes the cavitation effect. When the bubbles are compressed and burst, a powerful impact force is generated. During this cavitation phenomenon, when the bubbles close, an instantaneous high pressure of over 1000 atmospheres is formed. There are countless bursts and reconstructions in an instant, which can quickly loosen and remove grease, wax, and dirt attached to the surface, recesses, or hidden areas of the object, achieving a thorough cleaning effect without damaging the surface of the workpiece. This cavitation erosion effect is the basic principle of ultrasonic cleaning.
6. Cleaning Liquid Instruction
Suitable for cleaning in aqueous solutions. It is recommended to prefer neutral solvents/reagents.
7. Matters Need Attention Before Operation
- The machine should be placed in a well-ventilated and dry place.
- The system activation key of the ultrasonic generator is set to the “OFF” position.
- Fill the cleaning liquid in the 1st ultrasonic cleaning tank and 2nd ultrasonic rinsing tank with 2/3 or 3/4 of the entire tank.
- Avoid the cleaning liquid spill onto any electrical parts, especially the ultrasonic transducers.
- When there is no cleaning liquid in the cleaning tank, do not press the ultrasonic button to activate ultrasonic function. Otherwise, the ultrasonic transducers will be damaged.
- When there is no cleaning liquid in the cleaning tank or the liquid level is below the heating pipe, do not press the heating button to activate heating function; otherwise, the ultrasonic transducers and the heating pipes will be damaged.
- No object should come into direct contact with the bottom of the working tank. If any foreign object falls into the bottom of the tank, it should be removed immediately. Otherwise, it will damage the ultrasonic transducers or tank.
- Do not allow any liquid to splash onto the transducers and the ultrasonic generators.
- When there is excessive sediment in the cleaning tank, it is necessary to drain the liquid and rinse it clean in time.
- Do not drain the liquid until the the temperature of the liquid approaches room temperature. This is to prevent the deformation of the side tank of the heating pipe.
