Reasons for the failure of ultrasonic cleaning machine

The reasons for the failure of the ultrasonic cleaning machine: 1) The reasons why the nozzle does not spray water are generally: a) The water inlet and the water inlet filter are blocked. b) The air is sucked into the pipeline due to the broken pipe and the detergent nozzle is not inserted into the detergent.

If the insulation resistance value is not reached, generally the transducer is damp, you can put the whole transducer (excluding the plastic spray shell) into the oven and set it to dry at about 100 ℃ for 3 hours or use a hair dryer to dampen the resistance value So far. Generally, the output power of the ultrasonic power supply is normal after the vibrator is degummed, but due to the poor connection between the vibrator and the vibration surface, the vibration effect of the vibration surface is not good, and the vibrator may be burned out after a long time.

The principle of cavitation effect makes the cleaning machine ultrasonic. The principle of the ultrasonic cleaning machine is that the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the cleaning solution. The ultrasonic waves are dense and dense in the cleaning solution. The forward radiation of the liquid causes the flow of liquid to generate tens of thousands of small bubbles. These bubbles form and grow in the negative pressure area where the ultrasonic waves propagate longitudinally, and they quickly close in the positive pressure area. In the "cavitation" effect project, the closed air bubbles can form an instantaneous high pressure at atmospheric pressure. The continuous high pressure will cause a series of small "explosions" to continuously hit the surface of the object, causing the scale on the surface of the workpiece and the gap to quickly peel off.

The ultrasonic cleaning machine tank is made of high-quality stainless steel with strong elasticity and corrosion resistance, and an ultrasonic transducer vibrator is installed at the bottom; the ultrasonic generator generates high frequency and high voltage, which is transmitted to the transducer through the cable connection line, and the transducer and vibration The plates together produce high-frequency resonance, so that the solvent in the cleaning tank of the ultrasonic cleaning machine is cleaned by ultrasonic waves to clean the dirt. How the ultrasonic cleaning machine cleans the objects: the acceleration generated by the liquid particles. For the ultrasonic cleaner with higher frequency, the cavitation effect is very insignificant. At this time, the cleaning mainly depends on the ultra-precision cleaning of the dirt by the acceleration of the liquid particles under the ultrasonic impact on the particles.

Frequency selection The ultrasonic cavitation threshold of ultrasonic cleaning equipment is closely related to the ultrasonic frequency. Considering the choice of cleaning agent, the physical and chemical properties of the cleaning fluid have different effects on the cleaning effect.On the one hand, the cleaning chemical cleaning agent is selected from the nature of the dirt, on the other hand, the surface tension, vapor pressure, and the appropriate degree of cleaning agent dryness. Characteristics and ultrasonic cavitation are related to intensity.

Liquid molecules are more able to withstand pressure, but when they are subjected to tensile forces, their arrangement is prone to break, and such breaks often occur where there are impurities or bubbles in the liquid.
