Basic knowledge of ultrasonic cleaning machine

Some people know what to know about ultrasonic, what needs to be prepared, what cleaning basket, how much temperature is adjusted, what needs to be paid attention to, etc., the following editor will give you a brief introduction to the basics of ultrasonic cleaning machines. common sense.

1. The use of cleaning basket

When cleaning small parts and objects, net cages, that is, cleaning baskets, are often used. As the meshes cause ultrasonic attenuation, special attention must be paid. When the frequency is 28khz, it is better to use a mesh of 10mm or more.

Second, the choice of cleaning fluid temperature

The suitable cleaning temperature of the water cleaning solution is 40-60℃, especially when the temperature of the cleaning solution is low, the cavitation effect is poor, and the cleaning effect is also poor. Therefore, some ultrasonic cleaning machines have heating wires around the outside of the cleaning tank for temperature control. When the temperature rises, cavitation is prone to occur, so the cleaning effect is better. When the temperature continues to rise, the gas pressure in the cavity increases, causing the impact sound pressure to drop, reflecting the multiplication of these two factors.

The determination of the amount of cleaning fluid and the location of the cleaning parts

Generally, it is better that the liquid level of the cleaning liquid is higher than the surface of the vibrator by more than 100mm. Example: 300W, 24kHz liquid level is about 120mm high; 600W, 24kHz liquid level is about 150mm high. Because the single-frequency ultrasonic 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, it is better to choose the location of cleaning items should be placed at the volatility.
