< a href = "http://www.kejeme.com/news/xyxw/1532.html" > second-hand washing machine < / a > in the aspect of cleaning is not very clean, In terms of the household ultrasonic cleaner , it is relatively ideal, but the industrial second-hand ultrasonic cleaner for cleaning parts is really not ideal. After all, the performance of the second-hand ultrasonic cleaner will be much lower after permanent use, and in terms of configuration, the technology is still outdated. It's not as powerful as the new product technology!

        Take the cleaning effect of second-hand ultrasonic waves as an example. In terms of cleaning methods, the cleaning methods generally used in industrial cleaning include manual cleaning, organic solvent cleaning, steam vapor phase cleaning, high-pressure water jet cleaning and ultrasonic cleaning. Ultrasonic cleaning is internationally recognized as the most efficient and effective cleaning method at present, with a cleaning efficiency of over 98% and the highest level of cleanliness. In contrast, the cleaning efficiency of traditional manual cleaning and organic solvent cleaning is only 60% to 70%, and even the cleaning efficiency of meteorological cleaning and high-pressure water jet cleaning is less than 90%. Low cleaning cost      
          Among all cleaning methods, cleaning costs can be roughly divided into: equipment costs and consumption costs. The service life of second-hand ultrasonic cleaning equipment is approximately two years. Except that the purchase cost of the equipment is higher than that of manual cleaning and brushing with organic alkaline solvents, it is lower than that of gas-phase cleaning and high-pressure water jet cleaning. Regarding the consumption cost, with an effective size of 600 ×; 400× Take a 350mm ultrasonic cleaner with a power of 1KW and a price of approximately 10,000 yuan as an example. It consumes 1 kilowatt-hour of electricity for one hour of operation, with a cost of about 0.5 yuan. One kilogram of alkaline metal cleaner costs about 20 yuan and can be reused for 20 to 50 hours (depending on the degree of contamination), which is equivalent to 0.4 to 1 yuan per hour. The cleaning time for general workpieces is only 3 to 15 minutes, and one cleaning can simultaneously clean a certain number and volume of workpieces. Therefore, in terms of consumption cost, ultrasonic cleaning not only has the best cleaning effect but also has a cleaning cost of less than 0.04 yuan per piece, not to mention the labor cost savings, which is far lower than other cleaning methods. Avoid labor injuries.        
        In the past, complex mechanical parts that needed to be manually cleaned for a long time through heavy physical labor in dirty environments have not only improved the working environment, eliminated the damage caused by manual cleaning to the workpieces, and reduced the labor intensity after the application of ultrasonic cleaning machines, but also shortened the cleaning time to a quarter of the original on the basis of significantly improving the cleaning accuracy. Ultrasonic cleaning can also effectively reduce pollution and minimize the harm of toxic solvents to humans.
 
        No matter how complex the shape of the workpiece is, as long as it is placed in the cleaning solution and can come into contact with the liquid, the cleaning effect of ultrasonic waves can be achieved. Especially for workpieces with complex shapes and structures that cannot be completely and effectively cleaned by manual or other cleaning methods, it has a remarkable cleaning effect. The bubbles produced in the liquid during cleaning are very uniform, and the cleaning effect on the workpieces is also very uniform and consistent. Ultrasonic cleaning can achieve different effects depending on the solvent used, such as degreasing, rust removal or phosphating. When used in conjunction with cleaning agents, it can accelerate the separation and dissolution of contaminants and effectively prevent the corrosion of workpieces by the cleaning solution.
