Is mainly composed of ultrasonic transducer signal generator ultrasonic sonochemistry machine and the cleaning trough. Ultrasonic signal generator to generate high-frequency oscillation signal, through the transducer into tens of thousands of times per second high-frequency mechanical oscillation, in (medium) formed in the ultrasonic cleaning fluid, in the form of positive pressure and negative pressure high frequency variations in the cleaning fluid density and radiation spread forward, constantly watching the tiny bubbles in the cleaning fluid and constantly burst, this phenomenon is called cavitation effect. Bubble burst can form more than 1000 atmospheres of instantaneous high pressure, produce a series of explosions release enormous energy, on the surrounding a huge impact, thereby to impact of workpiece surface continuously, make the job a crack in the surface and dirt quickly peeling off, so as to achieve the aim of workpiece surface cleaning.
There are many factors affecting the effects of ultrasonic cleaning machine, mainly has the following kinds:
Ultrasonic power density: the higher power density, the stronger the cavitation effect, cleaning effect, the better, the faster the cleaning. For difficult cleaning artifacts appropriate USES high power density, appropriate USES low power density for precision workpiece.
Ultrasonic frequency: the frequency is lower, the better the cavitation, the higher the frequency, catadioptric the better the results. For simple surface appropriate USES low-frequency, for complex surface and deep blind hole Kong Yi using high frequency. (20 KHZ / 28 KHZ / 40 KHZ / 80 KHZ / 0.8 MHz)
Temperature: ultrasonic in 40 ℃ ~ 50 ℃ is the best. ultrasonic cutting machine The higher the temperature, the more dirt decomposition, but when the temperature reaches 70 ℃ ~ 80 ℃, then affect the ultrasonic function, reduce the cleaning effect.
Cleaning time: the longer the better the results, except for special materials.
The types of cleaning solution (medium) : according to different object, the choice of different parameters, in order to achieve the best cleaning effect.
Ultrasonic cleaning machine process is as follows:
Hot dip to ultrasonic rough washing, ultrasonic fine ultrasonic dispersion machine cleaning and ultrasonic rinse to compressed air to blow dry, hot air drying process, etc.
The user can according to the cleaning object appropriate increase or decrease the above process.
Principle:
When cleaning the workpiece is placed in ultrasonic cleaning tank containing organic solvent by strong ultrasonic cavitation effect, make the objects in a short time to be cleaned clean. Put artifacts in the advantages of the steam zone, workpiece touching the longevity of steam condensation, and with the effect of surface contamination, as the droplets falling away dirt, after distillation tank is placed in a certain time, lift parts to again, on the upper frozen zone and drying. Using organic solvent ultrasonic gas phase cleaning detergent, with a strong ability to dissolve dirt, again after ultrasonic cleaning function is more significant.
