The term "ultrasonic twisted transducer" is easy to understand for those in the industry who are familiar with ultrasonic cleaning machines. But how can outsiders who are not familiar with cleaning machines share common knowledge? 1. Perforation of the stainless steel vibrating surface: Generally, after 10 years of full-load use, the transducer may experience perforation of the vibrating surface. 2. De-bonding of the oscillator: Our transducer adopts a dual guarantee process of bonding and screw fastening. This situation usually occurs. 3. If the transducer oscillator sparks and the ceramic material breaks, it can be inspected by combining the naked eye and a megohmmeter. Generally, as an emergency measure, individual damaged oscillators can be disconnected without affecting the normal operation of other oscillators. 4. If the ultrasonic transducer gets damp, a megohmmeter can be used to check the plug connected to the transducer. By checking the insulation resistance value, the basic situation can be determined. Generally, the insulation resistance should be greater than 5 megohms. If the insulation resistance value cannot be reached, it is generally because the transducer is damp. The entire transducer (excluding the powder-coated shell) can be placed in an oven set at around 100℃ for drying for 3 hours, or a hair dryer can be used to remove the moisture until the resistance value returns to normal.
      The ultrasonic toroidal transducer, including a housing, a matching layer (i.e., sound window), a piezoelectric ceramic disc transducer, a backing, and an output cable, is characterized in that it also includes a Cymbal array receiver, which consists of an output cable, 8 to 16 Cymbal transducers, a metal ring, and a rubber gasket. The Cymbal array receiver is located above the disc-type piezoelectric transducer 3. The piezoelectric ceramic disc transducer is used as a basic ultrasonic transducer to emit and receive ultrasonic signals. The Cymbal array receiver is located above the disc-type piezoelectric transducer and serves as an ultrasonic receiver for receiving Doppler echo signals outside the frequency band of the disc-type transducer. It is mainly applicable to ultrasonic plastic welding machines, ultrasonic metal welding machines, ultrasonic cleaning machines, gas cameras, trichloride machines, etc.
