By taking advantage of the perfect combination of the physical cleaning effect of ultrasonic technology and the chemical effect of the cleaning medium, and optimizing the selection of ultrasonic frequency bands and power density, Achieve thorough and complete cleaning of oil stains, carbon deposits, gummy substances and other contaminants on the inside and outside of various components. Abroad, microwave cleaning technology is also adopted. Under the action of microwaves, cavities are formed on the surface of the parts to be cleaned, and then oil stains and paint fall off by themselves.

      Therefore, these new technologies should be vigorously promoted in car maintenance. This article provides an introduction to the application of ultrasonic technology in automotive maintenance. Some new technologies, new processes, new materials and new equipment have emerged in the maintenance and repair of automobiles. When repairing automobiles, it is necessary to clean the parts. One of the purposes is to inspect and classify the parts, which is convenient for discovering the damage of the parts and repairing it in time. The second is to ensure the quality of maintenance and assembly.
  1. Principles of Ultrasonic Cleaning Technology: Sound waves with frequencies higher than 20KHZ are called ultrasonic waves. The propagation of sound waves is also a way of energy transfer. There are tiny bubbles (cavitation nuclei) in the liquid. When ultrasonic waves propagate in the liquid in the form of alternating positive and negative pressures (with an alternating frequency of tens of thousands of times per second), these small cavitation nuclei will rapidly grow in the negative pressure zone due to the sudden generation of negative pressure, and then rapidly close and burst in the positive pressure zone due to the sudden generation of positive pressure. This is ultrasonic cavitation. Cavitation can concentrate the energy of the sound field. At the moment when cavitation bubbles collapse, the highly concentrated energy is released in the extremely small space of the liquid, forming an extraordinary high temperature (>4000℃) and high pressure (>5 ° C;107). When the workpiece to be cleaned is immersed in the cleaning solution, ultrasonic waves act on the inner and outer surfaces of the workpiece with a powerful cavitation effect. Therefore, it is particularly suitable for complex and porous smooth surfaces that cannot be scrubbed by hard objects. Ii. Instructions for the Use of Ultrasonic Cleaner When the water level in the cleaning tank is lower than the side vibration plate (the protruding part of the side plate in the length direction of the cleaning tank), the machine must not be started; otherwise, it will cause serious damage to the cleaning machine. Before turning on the power switch, make sure the power knob is at the minimum position. After turning on the power, gradually turn the power knob to the maximum position. When turning off the power, first turn the power knob to the minimum position and let it work for 2 to 3 minutes, and then turn off the power. Do not adjust the power knob by hand to prevent the cleaning solution from seeping into the potentiometer, which may cause the machine to fail to work properly or damage the equipment. In case of a sudden power outage during operation, please quickly turn off the power switch and turn the power knob to the minimum position to avoid repeated power on and off. The high-power module of this machine starts frequently, which may affect the service life of the equipment.
  Iii. Maintenance of Ultrasonic Cleaning Machines It is strictly prohibited to splash conductive liquids (such as water) into the air inlet at the top of the ultrasonic control cabinet. Otherwise, it will cause serious damage to the circuit system of the cleaning machine. Please keep the machine clean and turn off the power when not in use. Avoid any collision or violent vibration to the machine. Stay away from heat sources. Machines should be kept away from damp environments. The continuous operation time of the machine should not exceed 4 hours. If the continuous operation time is too long, the ultrasonic adjustment knob should be rotated to ";" 0” Keep the cooling fan working to continuously cool the ultrasonic control cabinet for at least 2 minutes without starting the ultrasonic cleaning. For a cleaning machine that has been in operation for a long time, before shutting down, the power knob should first be adjusted to zero position. Then, use its fan to work for another 3 to 6 minutes before turning it off to ensure that the heat inside the power supply is dissipated. The cleaning solution should be settled, filtered or replaced in a timely manner to ensure the cleaning effect.

    Ultrasonic technology can not only increase the speed and quality of car maintenance, but also enhance the reliability of cars, extend their service life, and at the same time reduce the consumption and cost of car maintenance, enabling enterprises to achieve higher economic benefits.
