21 Khz Ultrasonic Cleaning Transducer PZT-8 For Ultrasonic Washing Machine 70W
Special transducer for ultrasonic dishwasher:
Ultrasonic dishwasher uses the principle of ultrasonic cleaning: when ultrasonic wave passes through liquid medium, it will vibrate the liquid medium at a very high frequency and make the liquid molecules produce positive and negative shock waves. When the sound intensity reaches a certain value, the tiny cavitation bubbles in the liquid are rapidly grown and the instantaneous strong closure produces a strong micro explosion and shock wave that destroys the dirt on the surface of the cleaned object and falls off from the cleaned surface. Although the function of each cavitation bubble is not large, there are hundreds of billions of cavitation bubbles per second, which has good cleaning effect and characteristics. Because the ultrasonic can penetrate solid material and make the whole liquid medium vibrate and produce cavitation bubbles, so this cleaning method does not have the unwashed dead angle and the industry proves that the cleanliness of ultrasonic cleaning is high.
How to know ultrasonic transducer’s positive and negative electrode?----The electrode between two piezoelectric ceramics is positive.other electrode is negative.
How to connect ultrasonic transducer by cable?----All the ultrasonic transducers should be connected in parallel.The wire should pass the hole to coil junction,then soldered. It should avoid overlap welding.
How to choose the cable to connect ultrasonic transducer?
Use the enough soft silicone wire of above 1.2 square diameter
How to let ultrasonic transducer insulation and test?
Bare wire and tin welding parts covered by heat shrinkable casing and silicone coating sealing.
How to test ultrasonic transducer insulation?
Use 1500 v megohmmeter to measure insulation resistance in positive and negative electrode. The insulation resistance required more than 50 m Ω except for high humidity environment.
