The basic knowledge of ultrasonic cleaning machines is as follows:
1: Can frequency converters be used instead of ultrasonic generators?
The frequency output by the ultrasonic generator is generally
15KHz, 18KHz, 20KHz, 30KHz, 40KHz, 68KHz, 120KHz, 200KHz are higher, and the frequency converter does not have such high output frequencies.
2: How to adjust the ultrasonic generator?
Some ultrasonic waves, after being used for a period of time or when not in use, do not produce ultrasonic waves when turned on. If this is the case, please first determine whether it is a problem with the shock plate or the generator. If it is a problem with the generator, it is recommended to ask the manufacturer or a professional to adjust it. 3: Guide for selecting accessories for ultrasonic cleaning machines
When choosing ultrasonic cleaning machine accessories, it is important to find a reputable ultrasonic cleaning machine manufacturer, such as a company like ours. The accessories are made of genuine materials and will not be discounted. The service is up to standard and usually door-to-door service is available.
4: High frequency ultrasonic generator power supply
The main characteristics of high-frequency generator power supply products produced by ultrasound are:
It has a wide range of adaptability - suitable for various energy transducers.
Easy to operate - just design the adjacent frequency and the required adjacent power, there are only two proximity buttons, which can be seen at a glance.
Strong recognition performance - it can reach a good resonance state during operation within 0.01~0.05s. This power supply displays the current frequency and power after operation.

High frequency ultrasonic generator power supply
Preface
The ultrasonic cleaning equipment consists of an ultrasonic vibration head, a generator, and a tank body. The ultrasonic generator (hereinafter referred to as the generator) is essentially a power signal generator that generates a certain frequency of sine (or similar sine) signals. The development of ultrasonic generators is closely related to the development of power electronic devices, and can generally be divided into several stages: electronic tubes, analog crystal tubes, and switching transistors.
2. Principle of ultrasonic generator
Firstly, a signal generator is used to generate a specific frequency signal, which can be a sine signal or a pulse signal
Number, this specific frequency is the frequency of the transducer. Generally, ultrasonic frequencies used in ultrasonic equipment are 20KHz, 28KHz, 35KHz, and 40KHz; 135KHz or above is not yet widely used, but with the continuous development of precision cleaning in the future. I believe the usage range will gradually expand
