Why can’t the ultrasonic cleaning machine start without water?

The principle of ultrasonic cleaning is to rely on the cavitation of the liquid to achieve the purpose of cleaning. And in the case of “less liquid” or no water (liquid), can not start using. This is to protect the circuit of the cleaning machine to prevent the machine from burning out, because the ultrasonic vibration head in the mechanical high-frequency oscillation will generate a lot of heat (which is also the reason why the water becomes hot after a period of time), so the machine is designed to do the “anti-dry burn / under-liquid” circuit protection, in the case of cleaning machine under-liquid or no water, it will automatically remind or Stop the machine can not work, and forcibly open the machine will cause dry burning situation, ultrasonic cleaning machine ultrasonic vibration head will burn, the machine can not be used. And this is the reason why the ultrasonic cleaning machine without water can not start.


Under liquid: refers to the normal operation of the cleaning machine required liquid does not meet the most basic requirements; for example, the cleaning liquid level line is set to a height of 20 cm, below this figure is under the liquid.

Vibration head: also known as the vibrator / ultrasonic transducer, the working principle of high-frequency mechanical oscillation; is the core component of the ultrasonic cleaning machine, its role is to convert the ultrasonic frequency into mechanical kinetic energy, without it, the ultrasonic cleaning machine can not work, it is equivalent to an energy converter, so its official name is the ultrasonic transducer.

Ultrasonic cleaning principle: the principle of ultrasonic cleaning machine is mainly through the transducer, the power ultrasonic frequency source of acoustic energy into mechanical vibration, through the cleaning tank wall will be ultrasonic radiation to the cleaning liquid in the tank. Due to the radiation of ultrasonic waves, so that the micro bubbles in the liquid in the tank can be under the action of sound waves and thus maintain vibration. Destroy the adsorption of dirt and cleaning parts surface, causing fatigue damage to the layer of dirt and be barge away, gas-type bubbles of vibration to the solid surface scrubbing.
