In the ultrasonic cleaning process, the bubble will inhibit cavitation and reduce the cleaning capacity. As long as the bubble in the liquid is completely dragged away, the bubble in the vacuum core set can achieve the effect, this is the role of degassing function. In addition, let’s take a look at the three concepts of atmospheric pressure, positive pressure and negative pressure.
Atmospheric pressure: refers to the atmospheric pressure, which is the atmospheric pressure we usually generate in this atmosphere. The standard atmospheric pressure is 101,325 Pa (Pascal-universal unit of pressure). 100,000Pa = 100KPa, so the “standard atmospheric pressure” is usually expressed in 100KPa or 101KPa.
Positive pressure: A gas condition that is higher than atmospheric pressure. For example, when refueling a bicycle or car tire, positive pressure is generated at the outlet of the booster tube or booster pump.
Negative pressure: A state in which the gas is below atmospheric pressure, or what we usually call a “vacuum”. For example, when using a tube to drink a beverage, the tube is under negative pressure. Used to hang objects inside the suction cup also has negative pressure.
Ultrasonic cleaning machine is the high frequency vibration signal from the ultrasonic generator through the transducer into high frequency mechanical vibration to the solvent. Ultrasonic waves in the cleaning fluid in the forward radiation, so that the liquid produces tens of thousands of small bubbles with a diameter of 50-500μm, the ultrasonic cleaning machine in the small bubbles will also produce vibration under the action of ultrasound. These bubbles in the ultrasonic longitudinal propagation of the negative pressure zone to form and grow, and in the positive pressure zone, when the sound pressure reaches a certain value, the bubble will actively increase and then rupture.
Ultrasonic cleaning machine in the bubble rupture will produce shock waves. This will destroy the insoluble dirt and will be stripped of them to the ultrasonic cleaning equipment in the cleaning fluid. When the base particles are wrapped in oil and adhere to the surface of the cleaned parts, the oil will emulsify and separate out the solid particles, thus achieving the purpose of cleaning the parts.
In this process called “cavitation effect”, the closed bubble will form several hundred degrees of high temperature, can exceed 1000 atmospheres. The “explosion” continuously impacts the surface of the object, causing dust and dirt to fall from the surface and crevices, thus cleaning and purifying the surface. er pump.
