Frequency difference: the frequency of low-frequency ultrasonic cleaner is usually between 20 and 50 khz, the frequency of high-frequency ultrasonic cleaner is usually between 50 and 200 khz; the lowest frequency of the most used ultrasonic cleaner in industry is 28 khz, the frequency of most high frequency ultrasonic cleaning machines is 80khz.

The effect of the difference: ultrasonic low-frequency status of the liquid produced in the process of the bubble size, the cleaning of the objects relatively strong interaction, at the same time the low-frequency is easy to damage the corrosion of the surface of the workpiece; Ultrasonic cleaning machine high-frequency penetration, complex blind hole can be cleaned to.

The difference between noise: Low-frequency noise is much higher than high-frequency noise.

The difference between available products: low-frequency ultrasonic cleaning machine is mainly used for large parts of the surface, waste and the surface of the relatively high degree of integration of the workpiece, surface gloss does not require the object, for example, vehicle engines, pneumatic valves and other large workpieces; high-frequency ultrasonic cleaning machine is mainly used for the surface gloss requirements, the surface of the complex blind holes more workpieces, such as electronic parts, magnetic materials, silicon film, etc. .
