The input of the universal ultrasonic generator is a signal with a fixed frequency. The signal waveform is uncertain and can be sinusoidal or pulsed, but its frequency is fixed as the frequency of the transducer, generally 20, 25, 28, 33, 40, 60KHZ, etc. Through the internal conversion of the universal ultrasonic generator, its output is power signal, frequency tracking signal, etc.

As the output signal presents an unstable state with the change of input signal, some universal ultrasonic generators also contain feedback parts, which are mainly reflected in two aspects. On the one hand, the change of the input signal leads to the instability of the output power, resulting in irregular mechanical vibration of the transducer and poor cleaning effect. After adding the feedback part, the power feedback signal adjusts the output power so that it does not change with the change of the input signal and presents a stable state. The regular mechanical vibration of the transducer makes the cleaning effect better. On the other hand, the efficiency is the highest when the frequency of the transducer is at the resonant frequency point, but in practice, it cannot always work in the best state due to various reasons. Therefore, the feedback part plays its role to provide frequency tracking signal, and the signal sent by the control signal generator is always at the resonant point of the transducer to make it always work in the best state.

Power and frequency
While ultrasonic cleaning systems include generators, transducers and a cleaning tank, it is the universal ultrasonic generator that determines the main characteristics of the system. Therefore, choosing the properuniversal ultrasonic generator is important for obtaining the specified performance. The generator has to have the right operating specifications and capabilities required for the cleaning application. The transducers and tank size have to match the generator as well. If the right generator is not used, the ultrasonic cleaning system may work more slowly than expected or may not clean completely. The power of the generator is determined by the size of the parts to be cleaned. The parts have to fit into the cleaning tank and be submerged in the cleaning solution. For smaller parts, a basket to hold them off the tank bottom and away from the sides may be needed. The tank size has to be large enough so the largest parts or the basket will fit. The tank size, in turn, determines how much power is required to fill the tank evenly with ultrasonic waves. The generator frequency determines the intensity of the ultrasonic cleaning action. Low frequencies create comparatively large cavitation bubbles that deliver robust scrubbing and cleaning. High frequencies create smaller bubbles that clean gently. Depending on the cleaning application, the generator should be able to produce the corresponding frequency, multiple frequencies or a frequency range.

Control, operation and performance
An ultrasonic cleaning system is controlled from the universal ultrasonic generator. If remote operation is required, the generator has to be able to communicate with a remote control system. The controls may also vary the operating frequency slightly in a “sweep mode.” normally, the generator controls operate the generator at exactly the selected frequency. In some applications, this mode of operation results in uneven distribution of the ultrasonic waves in the cleaning tank. Such “hot” and “dead” spots can be caused by standing waves due to the tank and transducer configuration or by patterns induced from the shape of the parts to be cleaned. Continuously varying the frequency above and below the operating frequency by 2 to 3 khz often breaks up such standing waves and patterns, resulting in a more even distribution of the sound waves and the resulting cavitation bubbles. The universal ultrasonic generator can operate in standard sweep mode or in a special hyper mode to improve cleaning performance. Hyper mode allows the generator to fill the cleaning tank evenly with ultrasonic energy and clean all kinds of parts, even those with complex shapes, quickly and completely. This ultrasonic cleaning generator operates at 78 khz with 1200 watts of power and has an auto tuning function that keeps the frequency adjusted when operating conditions change.
