Want to know

special ultrasonic cleaning machine is generally installed on the production line for cleaning some specific objects. Quanyi electronics specializes in the production of ultrasonic cleaning machines with advanced technology and many years of manufacturing and sales experience. It occupies most of the Chinese market. You are welcome to replace the ultrasonic cleaning machines produced by our factory Introduction of typical ultrasonic cleaning equipment for soft magnetic devices: the cleaned objects are sent to the ultrasonic cleaning tank for cleaning from the stainless steel special mesh belt that can be driven at the feed inlet, and then discharged after spraying, drying and other processes, so that the cleaned objects can be packaged and stored directly
the ultrasonic cleaning effect of qycf series ultrasonic generator is not necessarily the same as (power) × Cleaning time), sometimes with low power, it takes a long time without removing dirt. If the power reaches a certain value, sometimes the dirt will be removed quickly. If the power is too large, the cavitation intensity will be greatly increased and the cleaning effect will be improved, but at this time, the more precise parts will also produce corrosion spots, which is not worth the loss. In addition, the cavitation at the vibrating plate at the bottom of the cleaning cylinder is serious and the water spot corrosion also increases. There is basically no problem when using organic solvents such as trichloroethylene, but when using water or water-soluble cleaning solution, it is easy to be corroded by water spots, If the surface of the vibrating plate has been damaged, cavitation corrosion at the bottom of the water under high power is more serious, so the ultrasonic power should be selected according to the actual use
the ultrasonic cleaning frequency of qycf series ultrasonic generator ranges from more than ten kHz to 100 kHz. When using water or water cleaning agent, the physical cleaning force caused by the action of holes is obviously beneficial to the low frequency. Generally, it is about 15-30 kHz. For parts with small gaps, slits and deep holes, high frequency (generally above 40KHz) is better, even hundreds of kHz. When cleaning clock parts, use 400kHz. If you use broadband FM cleaning, the effect is better
the optimum cleaning temperature of water cleaning solution is 40-60 ℃, especially in cold weather. If the temperature of cleaning solution is low and the cavitation effect is poor, the cleaning effect is also poor. Therefore, some cleaning machines wrap heating wires around the outside of the cleaning cylinder for temperature control. When the temperature rises, cavitation is easy to occur, so the cleaning effect is good. When the temperature continues to rise, the gas pressure in the cavity increases and the impact sound pressure decreases, reflecting the multiplication of these two factors
good cleaning effect, high cleanliness and consistent cleanliness of all workpieces. The cleaning speed is fast, the production efficiency is improved, and there is no need for manual contact with the cleaning liquid, which is safe and reliable. Deep holes, fine seams and concealed parts of workpieces can also be cleaned. No damage to the surface of the workpiece, saving solvent, heat energy, workplace and labor
the ultrasonic cleaning method exceeds the conventional cleaning methods, especially the surface of the workpiece is more complex, such as some mechanical parts with uneven surface and blind holes, and some products that are particularly small and have high requirements for cleanliness, such as parts of clocks and precision machinery, electronic components, circuit board components, etc, Ultrasonic cleaning can achieve ideal results
the action mechanism of qycf series ultrasonic generator mainly includes the following aspects: due to the strong shock wave generated when the cavitation bubble is broken, part of the dirt layer is stripped, dispersed, emulsified and fallen off under the action of the shock wave. Due to the bubbles generated by cavitation, the gap and gap between the dirt layer and the surface layer formed by impact penetrate. Due to the synchronous expansion and contraction of this small bubble and sound pressure, the physical force like peeling repeatedly acts on the dirt layer, the dirt layer is stripped layer by layer, and the bubbles continue to penetrate inward until the dirt layer is completely stripped. This is the secondary effect of cavitation. The impact of ultrasonic vibration of cleaning fluid on dirt in ultrasonic cleaning. Ultrasonic accelerates the dissolution of dirt by chemical cleaning agent, and the combination of chemical force and physical force accelerates the cleaning process
main parameters of ultrasonic cleaning machine:
1) frequency: ≥ 20kHz, which can be divided into low frequency, medium frequency and high frequency
2) cleaning medium: ultrasonic cleaning is adopted. Generally, there are two types of cleaning agents: chemical solvent, water-based cleaning agent, etc. The chemical action of cleaning medium can accelerate the effect of ultrasonic cleaning. Ultrasonic cleaning is a physical action. The two functions are combined to fully and thoroughly clean the objects
3) power density: power density = emission power (W) /emission area (cm2), usually ≥ 0.3w/cm2. The higher the power density of ultrasonic, the stronger the cavitation effect, the faster the speed, and the better the cleaning effect. However, for precision objects with high surface finish, long-time high-power density cleaning will produce “cavitation” corrosion on the surface of the object
4) ultrasonic frequency: the lower the ultrasonic frequency is, the easier cavitation will be generated in the liquid, the greater the intensity and the stronger the effect. It is suitable for the initial washing of workpieces (coarse and dirty). If the frequency is high, the ultrasonic wave has strong directionality, which is suitable for fine object cleaning
5) cleaning temperature: Generally speaking, the cavitation effect of ultrasonic at 30 ℃ – 40 ℃ is the best. The higher the temperature of the cleaning agent, the more significant the effect is. Generally, the working temperature of 50 ℃ – 70 ℃ is used in the practical application of ultrasonic.
