Ultrasonic cleaning machine working principle
Ultrasonic cleaning machine is a high-frequency oscillating signal from the ultrasonic generator, through the transducer into a high-frequency mechanical equipment oscillation and dispersed to the medium, cleaning solvent ultrasonic in the cleaning fluid sparsely diffuse forward, so that the liquid flow and the emergence of uncountable fine bubbles, the presence of fine bubbles in the liquid (cavitation nuclei) in the acoustic field of the Under the influence of vibration, when the acoustic pressure to a certain value, the bubble quickly raised, and then suddenly closed, in the bubble after the closure of the shock wave, then in the periphery, resulting in thousands of atmospheric pressure, the destruction of insoluble waste and then they are dispersed in the cleaning fluid, when the group particles wrapped in oil and adhering to the cleaning pieces of the surface, the oil is emulsified, solid particles that is to get rid of in order to achieve the cleaning pieces of the surface layer of the purification process effect. Because of the inherent penetrating nature of ultrasonic waves, so you can clean a variety of surface layer complex, special shape of the goods, the small round holes and crevices also have a good cleaning effect, not sound-absorbing or sound-absorbing coefficient of the object cleaning the best results.
Applications:
Application: (cleaning of adhesion: blood, gelatin, dust, fingerprints, blood stains, protein) syringes, surgical instruments, droppers, research laboratory appliances, glass containers, dental appliances, esophagoscopes, trachea bronchoscopes, proctoscopes, microscopes to disinfect, decontaminate, clean and clean the laboratory containers.
The structure of ultrasonic cleaning machine
Standard ultrasonic cleaning machine equipment consists of three parts: ultrasonic generator (also known as ultrasonic power supply), transducer and its auxiliary systems.
The ultrasonic generator will be converted into 28KHZ high-frequency electrical signals, through the cable to the transducer. Usually the ultrasonic transducer is fixed on the bottom plate of the cleaning tank, the cleaning tank is filled with liquid, when the transducer is added to the high-frequency voltage, its piezoelectric ceramic components in the electric field under the influence of the longitudinal vibration.
The ultrasonic transducer (also known as the sound head) is a class of high-efficiency transducer elements, can be converted into a powerful ultrasonic vibration of electrical energy, in the cause of ultrasonic vibration, as if it were a small piston rod, the amplitude of the vibration is very small, about only a few microns. But this vibration acceleration is very large (tens to thousands); groove side with many transducers, increase the same frequency and phase of the electrical energy, generated by this very large piston rod to carry out the reciprocating vibration, this type of vibration, is usually what we say ultrasound.
Other ultrasonic composition
(1) transducer: the application of special lead zirconate titanate PZT piezoelectric ceramic sheet composed of sandwich-type vibration head with high efficiency, long service life, and is not prone to failure advantages. Transducer application of special heat-resistant, vibration-resistant, high-viscosity resin glue plus a special way to carry out the fixed immobile never fall down, and can withstand high temperatures of 100 ℃ 150 ℃
(2) ultrasonic generator (power supply): the application of the power of the MOS tube ultrasonic generator, the circuit is advanced, the structure is detailed, together with the dexterity of trustworthy integrated automatic control system, to ensure that ultrasonic cleaner in various types of stable work under load. Stable work under load. Generator volume is small, novel appearance, very easy to operate, product quality and technical standards can be compared with similar products abroad, just debut will be highly valued by competitors, and more warmly welcomed by the majority of customers. Various kinds of ultrasonic generators can work independently, can also be used in parallel, and complete large-scale cleaning projects. Maintenance is easy, if one group fails, it will not affect the work of every other group, which is crucial for production lines.
(3) heating and temperature control system: electric heater using cast aluminum heating pad, acid and alkali resistance, long service life. The purpose of heating is to warm the cleaning agent to enhance the washing machine washing effect, the environment temperature automatic control system, can be adjusted randomly from a moderate range
(4) cleaning tank: cleaning tank application SU304 stainless steel by argon arc welding machine made of welded, the tank is equipped with dregs on the access port, heat insulation layer, etc.
(5) tank liquid circulation filtration system: in this system, a filtering device, the tank liquid to carry out the production line is essential. Equipped with filtration device, dynamic filtration of the tank liquid to maintain the cleanliness of the tank liquid. When the product workpiece out of the tank, through the filtered liquid flow through the upper part of the tank spraying link on the product workpiece to do a cleaning, easy to wash away the product workpiece out of the tank, in order to prevent the next channel of the tank liquid lead to pollution.
(6) conveying equipment: based on the shape of the workpiece being cleaned, volume, large quantities of clear ultrasonic cleaner conveying methods and control methods. Typical conveying methods are - hanging chain, mesh belt, double chain, stepper motor, electric hoist, self hoist, drum, wheel, gantry crane, mechanical arm, electric basket, push plate and so on.
(7) spray rinsing system: according to the surface layer of the workpiece to be cleaned, some cleaning machines are equipped with spray rinsing process, ultrasonic cleaning and spray cleaning organically combined together.
(8) drying system: according to the cleaned product workpiece, some cleaners are equipped with drying system, drying system mainly consists of electric heaters, fans, blowing nozzles, etc., the environment temperature automatic control system.
