first, the choice of power

Ultrasonic cleaning machine effect is not necessarily proportional to (power × cleaning time), sometimes with a small power, spend a long time also did not remove the dirt. And if the power reaches a certain value, sometimes the dirt will be removed quickly. If the choice of power is too large, cavitation intensity will greatly increase, cleaning effect is improved, but this time to make more precise parts also produce corrosion points, the loss is not worth it, and cleaning the bottom of the cylinder vibration plate at the cavitation is serious, water point corrosion also increased, in the use of trichloroethylene and other organic solvents, basically no problem, but the use of water or water-soluble cleaning fluid, easy to be subject to water point corrosion, if the surface of the vibration plate has been scarred,strong Power under the water bottom cavitation corrosion is more serious, so to choose the ultrasonic power according to the actual use of the situation.

Second, the choice of frequency

Ultrasonic cleaning frequency from 28kHz to 120kHz, in the use of water or water cleaning agent caused by the cavitation of the physical cleaning force is obviously beneficial to the low frequency, the general use of 28-40kHz or so. For small gaps, slits, deep hole parts cleaning, with high frequency (generally more than 40kHz) better, or even a few hundred kHz. on the clock parts cleaning, with 400kHz. if the broadband FM cleaning, the effect is even better.

Third, the use of cleaning basket

In the cleaning of small parts items, often use the net basket, due to the mesh to cause ultrasonic attenuation, to pay special attention. When the frequency is 28khz when using more than 10mm mesh is good.I suggest you have a look granboultrasonic cleaner. It can be used in blind cleaning

Four, the choice of cleaning fluid temperature

The most suitable cleaning fluid cleaning temperature of 40-60 ℃, especially in the cold if the cleaning fluid temperature is low cavitation effect is poor, cleaning effect is also poor. Therefore, some of the cleaning machine in the cleaning cylinder around the outside of the heating wire for temperature control, when the temperature rises after the cavitation is easy to occur, so the cleaning effect is better. When the temperature continues to rise later, the gas pressure within the cavitation bubble increases, causing the impact sound pressure to fall, reflecting the multiplicative effect of these two factors.

Five, on the amount of cleaning fluid and cleaning parts of the location of the determination

General cleaning fluid level above the surface of the vibrator more than 100mm is good. As a result of single frequency cleaning machine by the impact of standing wave field, wave section at the amplitude is very small, wave amplitude at the amplitude caused by uneven cleaning. Therefore the best choice of cleaning items should be placed at the location of the wave amplitude.

Six, ultrasonic cleaning process and the choice of cleaning fluid

In the purchase of cleaning systems before, should be cleaned to do the following application analysis: clear washed parts of the material composition, structure and number, analysis and clear to remove the dirt, these are to decide what kind of cleaning methods to use, to determine the application of water-based cleaning fluid or solvent prerequisites. The final cleaning process also needs to be verified by doing cleaning experiments. Only then can we provide a suitable cleaning system, design a reasonable cleaning process and cleaning fluid. Considering the physical properties of the cleaning fluid on the impact of ultrasonic cleaning, where the vapour pressure, surface tension, viscosity and density should be the most significant influencing factors. Temperature can affect these factors, so it will also affect the efficiency of cavitation.Any cleaning system must use a cleaning fluid.
