Classification and application of ultrasonic cleaning machine

In recent years, ultrasonic cleaning machine rapid development. With the unique cavitation effect cleaning principle and mechanized cleaning mode formed the characteristics of simple operation and thorough cleaning, so it is widely welcomed and rapidly popularized. At present, ultrasonic cleaning machine surface spraying processing industry, machinery industry, electronic industry, semiconductor industry, watch and jewelry industry, optical industry, textile printing and dyeing industry, etc

1, According to ultrasonic frequency classification

Those who understand ultrasonic cleaning machine know that ultrasonic frequency is an important indicator of the choice of ultrasonic cleaning machine, because it determines the cleaning effect of objects.

20khZ-80khz ultrasonic cleaning machine can generally meet most customers without special requirements (such as: hardware, machinery, electroplating, diamond, watches, glasses, jewelry and other industries). And some special industries on ultrasonic frequency requirements are relatively high, such as drug research, drug inspection, drug processing industry. The frequency is generally required to be between 40khz-90khz. Too high frequency will make it difficult to bond the transducer to the tank and the generator circuit. Some industries if there is a need for high frequency cleaning machine, you need to find a technical team and their own factory manufacturers to consult and provide demands, ultrasonic cleaning machine manufacturers will design a separate set of cleaning scheme for you.

2, According to ultrasonic power classification

The power of ultrasonic cleaning machine is an important indicator of customers, generally ranging from 50W to 2000W, it determines the number, size and effect of cleaning objects. So ultrasonic cleaning machine manufacturers are also very important to this index, in the laboratory, laboratory, research institute, drug inspection institute and other scientific research units, as well as small watches, glasses, jewelry and other units, the use of power is not large, (generally below 500W); The mechanical and electronic industries (such as: gears, bearings, engine cylinder block, screw, oil pump, nozzle, electronic circuit board, diamond, etc.) generally use industrial cleaning machine, the power used in the market is mostly about 500W-2000W; Surface treatment, hydraulic components, pharmaceutical and other industries to use more power, generally by 1000W or 2000W as the basic unit superimposed, roughly in 2KW-10KW, some also use more high-power ultrasonic cleaning line equipment or customized automatic ultrasonic cleaning machine.

3, According to the ultrasonic circuit classification

In recent years, most domestic cleaning machines in the same industry have adopted "large-scale integrated circuit" (commonly used IBGT module). Some small household ultrasonic cleaning machine of small power is generally used "self-excitation" circuit, the high power is generally used "he excitation" circuit. In the 60s and 70s, the common circuit is the "valve" circuit, which is characterized by: strong power, stable performance (some users are still in use today). However, its disadvantages are very obvious: (1) too large volume (2) too large power consumption (3) complex circuit, complex manufacturing (4) difficult procurement of supporting components and so on. At present this kind of model has been basically eliminated.

In the early 1980s, "vacuum tube" circuits were gradually replaced by "transistor" circuits. Compared with the former, the obvious advantages of this machine lie in: ① reduced volume, ② reduced power consumption, ③ saved cost, ④ improved assembly and debugging efficiency. The appearance of "transistor" circuit can be said to be a milestone event in ultrasonic cleaning industry.
