An automatic ultrasonic cleaning machine uses ultrasonic high frequency, through the transducer into high-frequency kinetic energy, and then acts on the liquid medium in the cleaning tank, so that the liquid cavitation, the continuous formation of countless fine bubbles, and quick bursts, resulting in an impact on the surface of the object, so that the surface dirt from, to achieve the effect of cleaning. So how exactly does it work?
Before introducing this working principle, let's first understand, what is ultrasound. Ultrasound is scientists will be the number of vibrations per second called the frequency of sound, it is the unit of Hertz (Hz). We human ears can hear the frequency of sound waves for 20Hz ~ 20,000Hz (20KHz). When the vibration frequency of sound waves is less than 20Hz or greater than 20KHz, we will not be able to hear. Therefore, we call the frequency of sound waves higher than 20,000 Hz “ ultrasonic ” Here to explain, many people use automatic ultrasonic cleaning machine equipment, and hear the buzzing sound, which is thought to be the sound of ultrasound that is only the liquid in the cavitation of the sound produced.
The automatic ultrasonic cleaning machine on the ultrasonic frequency is generally 28KHz or more. High up to 128KHz or more, commonly used is 40KHz, this frequency is more general and suitable for most of the workpiece cleaning. The lower the frequency, the lower the delicacy of cleaning, but the strength will be stronger.
Conversely, the finer the cleaning, the strength will be weakened. Then this frequency through the transducer also known as ultrasonic drive power, electronic box, or ultrasonic controller, is an important part of the high-power ultrasonic system. In the high-frequency ultrasound drive, the transducer to hundreds of thousands of times per second frequency vibration, this vibration is transmitted to the cleaning tank fastened to the above, and through the cleaning, the tank will transfer kinetic energy to the liquid in the tank. In this high-frequency vibration, the liquid will produce cavitation.
Automatic ultrasonic cleaning machine trip reason analysis!
With the continuous development of the cleaning industry, more and more industries and enterprises are using an automatic ultrasonic cleaning machines. The use of the process will always encounter a variety of conditions, automatic ultrasonic cleaning machine tripping is a very common fault.
The automatic ultrasonic cleaning machine tripping a possible reason may be the circuit caused by a short circuit, the line is wrongly connected or line aging may cause the circuit to short circuit phenomenon. The second reason may be a rectifier bridge short circuit, automatic ultrasonic cleaning machine occurs rectifier bridge short circuit will also cause the use of process of tripping, a good solution is to change the new rectifier bridge. Then a reason and the cleaning frequency setting, if the cleaning of too many items at the same time set the cleaning frequency is too high, it is also easy to produce the tripping phenomenon.
For the tripping phenomenon to be a regular fault, it is necessary to find the reason for this, and then get a solution according to the reason.
