The utility model is mainly composed of an ultrasonic signal generator transducer and a cleaning groove. Ultrasound signal generator generates high frequency oscillation signal, which is converted into tens of thousands of high frequency mechanical oscillations per second by transducer. Ultrasound is formed in cleaning fluid (medium). Ultrasound radiates forward densely and alternately in the way of positive pressure and negative pressure at high frequency, which causes numerous tiny bubbles and breaks up continuously in cleaning fluid. This phenomenon is called cavitation effect. Should. When the bubbles burst, instantaneous high pressure above 1000 atmospheric pressure can be formed, resulting in a series of explosions, releasing huge energy, forming a huge impact on the surrounding area, thus continuously impacting the surface of the workpiece and making the worksheet work.
The dirt in the surface and crevice peels off rapidly, so as to achieve the purpose of surface purification of the workpiece.

There are many factors affecting the effect of ultrasonic cleaning machine, mainly the following:

Ultrasound power density: The higher the power density, the stronger the cavitation effect, the better the cleaning effect and the faster the cleaning speed. For hard-to-clean workpiece, high power density should be used, and for precision workpiece, low power density should be used.

Ultrasound frequency: The lower the frequency, the better the cavitation, the higher the frequency, the better the catadioptric effect. Low frequency is suitable for simple surface and high frequency for complex surface and deep hole blind hole. (20KHz/28KHz/40KHz/80KHz/0.8MHz)

Cleaning temperature: Ultrasound has the best time and space at 40 ~50 ~C. The higher the temperature, the more conducive to decomposition of pollutants, but when the temperature reaches 70 80 C, it will affect the role of ultrasound and reduce the cleaning effect.

Cleaning time: The longer the cleaning time, the better the effect, except for special materials.

The type of cleaning solution (medium): According to different objects, different parameters are selected to achieve the best cleaning effect.

The flow chart of the ultrasonic cleaning machine is as follows:

Hot soaking ultrasonic roughing ultrasonic cleaning ultrasonic rinsing compressed air drying hot air drying and other processes.

Users can appropriately increase or reduce the above process according to the cleaning object.

Principle:

When cleaning, the workpiece is placed in the ultrasonic cleaning tank with organic solvents. Through strong ultrasonic cavitation, the cleaned object is cleaned in a very short time. Place the workpiece in the steam zone of the cleaning machine. The workpiece encounters steam condensation and acts on the surface dirt of the workpiece. With droplets falling, the dirt is taken away. After a certain period of time in the distillation tank, the workpiece is lifted up and placed in the upper freezing zone for drying. Ultrasound gas cleaning uses organic solvent as cleaning agent, which has a strong ability to dissolve dirt, and after ultrasonic cleaning, the function is more significant.

Advantages of Suzhou Jiahui Ultrasound Cleaning Machine:
Http://www.jhsonic.com 1.Savings: Automatic recovery system saves a lot of organic solvents and significantly reduces production costs. 2. Safety: (special requirements can be added to the riot control system) There are refrigeration systems, automatic recovery systems using organic solvents are not easy to volatilize, reduce air pollution, workers work in a safe and comfortable environment.
3. The cleaning speed is fast and the cleaning effect is good.
4. Environmental protection: reduce the emission of toxic solvents and odorous gases.
5. No damage to cleaning materials

Suzhou Jiahui Ultrasound Cleaning Equipment (http://www.jhsonic.com) has been widely used in machinery, electronics, optics, medicine, electroplating, painting and vacuum coating pretreatment industries. It is especially suitable for parts with complex surface shape, such as slits, grooves, deep holes and oblique holes on precise workpieces, and can remove grease, rust and oxide scales on the surface of parts at the same time. Especially for the pharmaceutical industry, all kinds of glass and surgical equipment cleaning effect is the most ideal, not only to achieve the purpose of cleaning, but also to the glass wall attached to a variety of microorganisms, bacteria play a smashing role, to achieve the role of cleaning, disinfection and sterilization.
