The difference between traditional cleaning methods and today's ultrasonic cleaning machines:
The traditional method of cleaning is to soak and wash, or to heat if necessary:
1, immersion cleaning, that is to be cleaned parts, parts soaked in cleaning fluid, with the help of cleaning fluid and stains between the physical and chemical reactions and stains gradually soften, loose gradually into a free state, finally, from the zero, component surface off. The soaking time is long and the efficiency is low. However, it has the advantages of simple and clear cleaning equipment and less manual work, so it has been widely used.
Auxiliary heating is a cleaning method that heats the cleaning solution until it boils. The cleaning performance of the cleaning fluid is further enhanced under the condition of heating. At the same time grease and grease because of the temperature rise and softening or melting, cleaning fluid is heated up and down natural convection, so that stains from the clean workpiece is easy to clean down. Scouring is more efficient than soaking.
As a whole, the cleaning equipment adopted for soaking cleaning mainly comprises a tank body and a heating device. However, the traditional cleaning effect can not keep up with the ultrasonic cleaning machine, the most prominent problem is that the cleaning effect is not good, and the dead corner can not be cleaned. The ultrasonic cleaning machine is generally made up of transducer, ultrasonic generator, heating and temperature controller, tank body, tank liquid circulation filtration device, conveying equipment, spray rinsing system, drying system. The cleaning effect is much higher than the traditional cleaning method.
The principle of the ultrasonic cleaning machine is that the high-frequency oscillating signal sent out by the ultrasonic generator is transferred into the high-frequency mechanical oscillating signal by the transducer and propagates into the medium cleaning solvent, it makes the liquid flow and appears countless tiny bubbles with diameter of 50-500μm. The tiny bubbles existing in the liquid vibrate under the influence of sound field. This kind of bubble in the ultrasonic longitudinal transmission of negative pressure area, growth, but in the positive pressure area, when the sound pressure reached a specified set value, the bubble rapidly increased, suddenly closed. And when the bubble closes, it creates a shock wave that creates thousands of atmospheres around it, destroying the insoluble dirt and dispersing it into the cleaning fluid. When the solid particles are coated in oil and adhere to the surface of the cleaning piece, the oil is emulsified and the solid particles are removed, thereby realizing the effect of cleaning the parts. In a process known as “Cavitation,” bubble closure can produce hundreds of Baidu temperatures and instantaneous high pressures of more than 1,000 barometric pressures, continuous generation of instantaneous high pressure as a series of small“Explosion” again and again impact the surface of the object, so that the surface of the object and the cracks of the stain quickly fall off, thus achieving the object surface cleaning effect.
Therefore, the ultrasonic cleaning machine is currently the most high-tech cleaning equipment in many industries, and the object favored by the public is also reasonable, the advantages are: faster speed, high efficiency, quick cleaning, to ensure non-destructive workpiece, whether complex, difficult to wash the workpiece ultrasonic cleaning machine can achieve the best cleaning effect you can.
