The working principle of ultrasonic glass cleaner

by:Enkong     2021-05-25
Ultrasonic washing machine to clean glass is to use the above 20 KHZ high frequency signals, through the transducer converts electrical energy to the high frequency of mechanical oscillation and the incoming to the cleaning fluid. In ultrasonic cleaning fluid density and radiation forward, make the liquid flow and produces tens of thousands of tiny bubbles. The formation of the tiny air bubbles are formed in the negative pressure zone of ultrasonic longitudinal transmission and growth ( Inflation) , and in positive pressure area quickly closed ( The explosion) 。 The formation of the tiny air bubbles, growth and rapid closure is called ( 空化) The phenomenon of cavitation effect. Air bubbles in the cavitation phenomenon of closed more than 1000 atmospheres of instantaneous high pressure formation, continuously produce flash like a string of small 'explode' constant bombardment cleaning the surface, cause the crack in the cleaning of surfaces and peeled off the dirt quickly. The process of cavitation is the principle of ultrasonic wave washing machine of glass. Use of ultrasonic cleaning machine cleaning glass. Its working process principle to understand something. Cleaning refers to remove liquid and solid pollutants, the workpiece surface to surface must be clean. Cleaning process is the medium, the pollutants, the interaction between the workpiece surface, is a complex process of physics and chemistry. Cleaning with not only the nature of the pollutant type, form and the degree of adhesion on, and the physical and chemical properties of cleaning medium, cleaning performance, the material of workpiece, surface state, but also with the cleaning conditions such as temperature, pressure and additional ultrasonic vibration, external mechanical forces and other factors. So, choose the scientific and reasonable cleaning process, must process analysis.
