Ultrasonic cleaning tank mainly consists of the following components:
|
|
 |
|
• Cleaning tank:
Washing the objects to be polished. Besides, heating and temperature control devices can be installed.
• Ultrasonic transducer:
Piezoelectric ceramic transducers convert electrical energy into mechanical energy, produce ultrasonic waves in the liquid.
• Ultrasonic generator:
Provide the necessary electrical energy for transducer, and convert the input frequency from 50KZ to the frequency required by ultrasonic transducers. |
High-frequency transducer converts electrical energy into mechanical energy, there will be a very small amplitude and high frequency vibration transmitted to the cleaning solution tank. Under the action of the transducer, the cleaning liquid inside will continuously generates lots of small bubble which instantly burst, also accompanying high temperature and atmospheric pressure, the energy from bubble burst acts on the workpiece to achieve cleaning effect, this phenomenon is known as "cavitation effect ".
We can understand the working principle of ultrasonic cleaning tank by cavitation effect in liquid medium. the cleaning process normally work at the frequency between 20 and 120 KHz. The lower frequency causes the bigger and powerful cavitation bubbles, on the contrary, the higher the frequency causes the tiny and gentle bubbles. Besides, the workpiece can't be placed on the bottom of stainless steel tank, in that case, there will be no cavitation effect occurring due to the part of workpiece not in contact with solution.
From the principle of ultrasonic cleaning tank, it's not difficult to understand why its cleaning efficiency and result are excellent.
First of all, no matter how complex shape of workpiece, put it in the cleaning tank, so long as they can contact with liquids, ultrasonic cleaning effect can be achieved.
Secondly the bubbles in cleaning tank are very uniform to guarantee the consistency of the cleaning effect.
Third, cleaning agents are used to accelerate dissolution, and separate contaminant from objects, together with ultrasonic cleaning tank, can greatly improve cleaning effect.
Fourth, no need for manual cleaning, the whole cleaning process is completed in the ultrasonic cleaning tanks, to prevent the damage of the workpiece by hand washing, also can avoid contacting with cleaning agent.
So far ultrasonic cleaning tank has designed for different types to meet specific requirement, precision cleaning is almost applied to every industry such as:
Machinery, surface treatment, medical treatment, Instrument, electronics, optical, semiconductor, watch and jewelry, petrochemical, textile printing and dyeing, etc.
