1 Use of cleaning cage

When cleaning small parts, mesh cages are often used, and special attention should be paid to the ultrasonic attenuation caused by the mesh. When the frequency is 28khz, it is better to use a mesh of more than 10mm.

2 Selection of cleaning fluid temperature

The most suitable cleaning temperature of the water cleaning solution is 40-60 °C, especially in cold weather, if the temperature of the cleaning solution is low, the cavitation effect is poor, and the cleaning effect is also poor. Therefore, some cleaning machines wind the heating wire outside the cleaning cylinder to control the temperature. When the temperature rises, cavitation is easy to occur, so the cleaning effect is better. When the temperature continues to rise, the gas pressure in the cavitation increases, causing the impact sound pressure to drop, reflecting the multiplication of these two factors.  About the amount of cleaning fluid and the location of cleaning parts    Generally, it is better that the cleaning fluid level is 100mm higher than the surface of the vibrator. Example 300W, 24kHz liquid level is about 120mm high; 600W, 24kHz liquid level is about 150mm high. Because the single-frequency cleaning machine is affected by the standing wave field, the amplitude at the node is small, and the amplitude at the wave amplitude is large, resulting in uneven cleaning. Therefore, the best choice for cleaning items should be placed at the amplitude.
