The principle and characteristics of laboratory ultrasonic cleaning machine
Date: 2024-09-13Read: 48
The laboratory ultrasonic cleaning machine is a cleaning device that uses the mechanical energy generated by high-frequency sound waves to cause the cleaning liquid molecules to oscillate greatly and achieve cleaning effects. This device is widely used in the fields of pharmaceuticals, chemicals, manufacturing, and laboratories, and has the characteristics of high efficiency, environmental protection, and energy conservation.
The laboratory ultrasonic cleaning machine is mainly composed of ultrasonic generator, cleaning tank, cooling system, control system and other components. The cleaning principle is to use an ultrasonic generator to convert electrical energy into high-frequency mechanical waves, generating sound waves with frequencies above 20kHz. This causes the cleaning solution to undergo compression expansion reciprocating motion with an electronic film under the action of sound waves, thereby forming a large number of bubbles in the medium.
The formation process of bubbles is that liquid molecules form extremely small bubbles under the action of ultrasound. The bubbles are further stretched by the sound waves and become larger. Eventually, the bubbles burst and release short-term jets of high temperature, high pressure, and high speed, which impact, shear, and friction the dirt surface, achieving a cleaning effect. Due to the formation of bubbles being related to the frictional heat between liquids, an increase in liquid temperature also helps to increase the number and duration of bubbles, further improving the cleaning effect.
The laboratory ultrasonic cleaning machine mainly has the following characteristics:
1. High cleaning efficiency
The laboratory ultrasonic cleaning machine has high cleaning efficiency and can clean pinholes and dead corners. After cleaning, the surface of the item becomes dry. The cleaning solution can effectively remove dirt in a short period of time, avoiding the drawbacks of traditional gravity cleaning or chemical cleaning. Meanwhile, the flow rate and temperature of the cleaning solution can be adjusted to flexibly clean different types of items.
2、 高安全性
The cleaning solution of the laboratory ultrasonic cleaning machine can selectively use water and other formulated cleaning solutions, while organic solvents and solvents harmful to human health and the ecological environment do not need to be used. Moreover, the cleaning noise is very low and will not have a negative impact on laboratory work.
3. High sensitivity
The vibration wavelength of the laboratory ultrasonic cleaning machine cleaning solution is millimeter level, which can make the cleaning solution molecules reach high speed and strength in a very small space. The high-speed jet formed can remove individual dirt particles, dust, and bacteria from the surface without leaving any dead corners. At the same time, the cleaning solution will not have any impact on the surface of the item, and there will be no negative effects such as reaction or corrosion.
4. High energy efficiency
The cleaning method of laboratory ultrasonic cleaning machine is energy-saving, and the cleaning solution can be reused, which has a protective effect on the environment. During the cleaning process, the energy dissipation in the cleaning solution can be regulated and minimized, achieving high cleaning efficiency while saving energy and reducing emissions.
