Ultrasonic cleaning machines are widely used in the machinery industry, surface treatment industry, instrument and meter industry, medical industry, electronics industry, semiconductor industry, watch and jewelry industry, chemical and biological industry, optical industry, textile printing and dyeing industry, petrochemical industry, etc. For those parts with complex surface shapes, such as slits, grooves, deep holes and blind holes on precision workpieces, ultrasonic cleaners can simultaneously remove oil stains, rust and oxide scale from the surface of the parts. It has the most ideal cleaning effect on various glassware and internal and surgical instruments in the pharmaceutical industry. It not only achieves the purpose of cleaning but also crushes various microorganisms and bacteria adhering to the inner and outer walls of glassware, thus achieving the effect of cleaning, disinfection and sterilization. 1. Determine the size of the equipment and material baskets based on the size of the workpieces to be cleaned and the output (including the output that will be achieved in future development), that is, determine the size of the equipment and material baskets. Second, determine whether a single ultrasonic wave can clean the workpiece thoroughly based on its material and the requirements to be achieved during the cleaning process, such as whether additional processes like spraying or drying are needed. You can also ask your peers what kind of process they use, or consult the manufacturer of ultrasonic waves to determine the cleaning process. Iii. Determine the power and frequency of the ultrasonic waves based on the above two points; 1. The ultrasonic cleaning frequency ranges from 20kHz to 100 KHZ. When using water or water-soluble cleaning agents, the physical cleaning force caused by cavitation is obviously more favorable for low frequencies, and generally around 28 to 40kHz is used. For cleaning parts with small gaps, narrow slits and deep holes, high frequency (generally above 40kHz) is better, or even several hundred kHz. For rust removal, it is best to choose a band with a lower frequency. When the ultrasonic power reaches an appropriate value, dirt can be removed quickly. If a higher power is chosen, the cavitation intensity will increase significantly, and the cleaning effect will be improved. However, at this time, it will cause corrosion points on more precise parts and also accelerate the cavitation of the ultrasonic vibration plate. Especially when water or water-soluble cleaning solutions are used, it is prone to water point cavitation. If the surface of the vibration plate has already been damaged, cavitation and cavitation at the bottom of the water will be more severe under high power. Therefore, the ultrasonic power should be selected according to the actual usage situation. 4. Choose a manufacturer with a good reputation and strong after-sales service guarantee, and sign a supply contract. If necessary, a technical agreement can also be signed. This can avoid unnecessary troubles and fraud by unscrupulous enterprises. With the industry's increasing standards for products and the growing attention to environmental protection, the sales of various cleaning equipment, including ultrasonic cleaning machines, have risen sharply. Data shows that in the past two years, the number of brands and models of ultrasonic cleaning equipment on sale has been increasing year by year. Every year, nearly 200 new models from dozens of brands are launched and enter the cleaning equipment market. Industry analysts believe that the advent of the era of widespread ultrasonic cleaning equipment will enable ultrasonic cleaning equipment to enter ordinary households, large and small enterprises, just like traditional household appliances, and become one of the essential items in home life and industries.
