In recent years, the rapid development of ultrasonic cleaning machine. Relying on the unique cavitation effect cleaning principle and mechanized cleaning method, the formation of a simple operation, thorough cleaning characteristics, and thus widely welcomed and rapidly popularized. At present, ultrasonic cleaning machine surface spraying treatment industry, machinery industry, electronics industry, semiconductor industry, watch and jewelry industry, glasses industry, textile printing and dyeing industry, etc. has formed a complete industrial system. The following will explain in detail its classification and application.
1, according to the classification of ultrasonic frequency
People who understand the ultrasonic cleaning machine know that the ultrasonic frequency is an important indicator of the choice of ultrasonic cleaning machine, because it determines the cleaning effect of the cleaning object.
20KHZ-80KHZ ultrasonic cleaning machine can generally meet most of the customers without special requirements (such as: hardware, machinery, electroplating, diamonds, watches, glasses, jewelry and other industries).
Some special industries have higher requirements for ultrasonic frequency, such as pharmaceutical research, pharmaceutical inspection, pharmaceutical processing industry, etc.. The general requirements of the frequency between 40KHZ-90KHZ.
Too high a frequency will make the transducer and the tank and the generator circuit joint work with some difficulty. In some industries, if there is a demand for high frequency cleaning machine, you need to find a manufacturer with a technical team and your own factory to consult and provide the claim. Ultrasonic cleaning machine manufacturers will design a separate cleaning program for you.
2, according to the ultrasonic power classification
Ultrasonic cleaning machine power is actually an important indicator of the customer, generally ranging from 50W to 2000W, which determines the number of cleaning objects, size and effect. So ultrasonic cleaning machine manufacturers also attach great importance to this indicator.
In laboratories, laboratories, research institutes, drug testing institutes and other scientific research units, as well as small watches, glasses, jewelry and other units, the use of power is not high (generally below 500W).
And mechanical and electronic industries (such as: gears, bearings, engine blocks, screws, oil pumps, injectors, electronic circuit boards, diamond, etc.) generally use industrial cleaning machine, power in the 500W-2000W or so.
Surface treatment, hydraulic components, pharmaceutical plants and other industries use more electricity. Generally to 1000W or 2000W as the basic unit of superposition, about 2KW-10KW, some use more power ultrasonic cleaning line equipment or custom automatic ultrasonic cleaning machine.
3, according to the ultrasonic circuit classification
In recent years, China’s domestic counterparts in the industry most of the cleaning machine using large-scale integrated circuits (commonly used IBGT module). Some small power small domestic ultrasonic cleaning machine generally uses self-excited circuit, high-power general use of his excitation circuit.
1960 to 1970, the commonly used circuit is the electronic tube circuit, which is characterized by strong power and stable performance (some users use it to this day).
But its disadvantages are very obvious: ① excessive volume; ② excessive power consumption; ③ wiring complex, cumbersome manufacturing; ④ supporting components procurement difficulties, etc.. At present, this model has been basically eliminated.
In the early 80s, the electronic tube circuit was gradually replaced by the transistor circuit. Compared with the former, the obvious advantages of this model are: ①reduced volume; ②reduced power consumption; ③saved cost; ④improved assembly and debugging efficiency. The emergence of the transistor circuit can be said to be a milestone event in the ultrasonic cleaning industry.
With the rapid qualitative changes in science and technology, transistor circuits were quickly replaced by new circuits. After entering the 90s, a variety of digital circuits quickly impacted the ultrasonic cleaning industry. Prominent among them is the application of large-scale integrated circuits, which is a major technological leap in the ultrasonic cleaning industry. At present, most of China’s domestic ultrasonic cleaning industry also uses this circuit.
In summary, most of the power ultrasonic products to ultrasonic cleaning machine. It is worth mentioning: ultrasonic thickness gauge, ultrasonic flaw detector, ultrasonic EDM leak detector, etc. do not belong to the power ultrasonic family, should be classified in the detection of ultrasonic series. Ultrasonic crusher, sonic biochemical instrument, sonic punching machine, sonic deburring machine, sonic engraving machine and other products are also in the rate ultrasound range, but because the transducer are conical, which is very different from the ultrasonic cleaning category. Although there is crossover in the product market, each plays a different role.
