Selection Differences between Laboratory and Industrial Ultrasonic Cleaning Machines
The two most important applications of ultrasonic cleaning machine are the cleaning of laboratory test vessels and industrial production of machinery, chemical industry, electronics, hardware, electroplating, pharmacy, etc.
Laboratory ultrasonic cleaners, commonly known as ultrasonic cleaners and ultrasonic cleaners, are generally small ultrasonic cleaners. In addition to laboratory cleaning, these cleaners are also often used for small extraction tests, solid-liquid and liquid-liquid mixing, oscillation and emulsification, liquid displacement and defoaming, cell crushing, etc. Features of this type of cleaning machine: ultrasonic transducers in 40KHZ frequency band with relatively low noise are mostly used; The stainless steel body pulling trough with beautiful appearance is often selected as the cleaning trough; The generators are mostly power tube driven and controlled circuits; Generally, the structural design of the integrated cleaning tank and control circuit, which are more convenient for the laboratory, is adopted, taking up less space; In addition, such instruments are equipped with functions such as power regulation and time control.
The types of industrial ultrasonic cleaning machines are more complex than those of laboratory ultrasonic cleaning instruments, and their shapes and processes are different due to different cleaning applications in specific industries. In addition to the ultrasonic cleaning line, the separate structure of cleaning tank and generator is adopted, which can better meet the actual needs of factory production. (Of course, some enterprises with good production environment can choose the integrated structure); The frequency of the transducer also varies with the characteristics of the workpiece to be cleaned, ranging from 20KHZ to 120KHZ. Generally, the transducer in 20KHZ and 28KHZ is used for cleaning the dirt that is difficult to remove. Generally, the transducer in high frequency is used for cleaning the high-precision small particles. Some complex cleaning processes often use the cleaning equipment in low frequency range for ultrasonic roughening, and then use the ultrasonic cleaning equipment in higher frequency range for fine cleaning; More diversified structural forms, including slot type (single slot, double slot and multi slot) and shock plate type
