How does an Ultrasonic Cleaner clean? 

An ultrasonic cleaner is simply a metal tank that has pizeo ceramic transducers bonded to the bottom or side. These transducers have a unique property of changing size almost instantly when excited by an electrical signal. When excited the transducer increases in size and causes the tank bottom or side to move. This creates a compression wave in the liquid of the tank. By using an electrical generator that puts out a high frequency signal the transducer rapidly induces compression and rarefaction wave in the liquid. During the rarefaction cycle the liquid is torn apart. This creates a vacuum cavity within liquid. These cavities will grow larger and smaller as the compression wave are continued. When the cavity reaches a certain size the cavity can no longer retain its shape. The cavity collapses violently and creates a temperature of 5,000 degrees centigrade and a jet of plasma that impacts against whatever object is in the tank. There are millions of these bubbles created and collapsing every second in an ultrasonic tank.

Ultrasonic Detergent Tank – The ultrasonic detergent tanks are the primary means of removing the particulates from your parts. In a high end cleaning system they are designed to minimize the retention of particulates. A series of ultrasonic detergents tanks are used for high end cleaning. The lowest frequency tank is first them immersion in a spray rinse tank to flush off any remaining particles and soap. The next step is a cleaning in a higher frequency tank to remove smaller particles. Followed by another spray rinse, the final step is the highest frequency tank to remove the smallest particles, again followed by a spray rinse.

Spray Rinse Tank – A spray rinse tank is usually made of polypropylene and is slightly larger that the ultrasonic tanks in the system. It has 2 or more spray bar with multiple nozzles in them. These can be adjusted to focus the spray of DI water on load of parts. All wet parts are designed to be compatible with DI water. A point of use DI water heater with a spray rinse tank to provide more effective rinsing. Whenever a load of parts is removed from an ultrasonic cleaning tank the parts should be rinsed. Any loose particulates are removed and the majority of the detergent film is removed. The load of parts is now ready for the next stage of cleaning.

Ultrasonic Rinse Tank – An Ultrasonic rinse tank is a standard ultrasonic tank that has a continuous DI water inflow from a regulated source. The amount of DI water can be controlled from a valve either manually or PLC controlled. The DI water overflow a dam and carries any particulates out of the tank. The ultrasonic help keep the particulates from redepositing on the parts. The frequency of the ultrasonic rinse tank is usually the highest in the cleaning system.
