The function of ultrasonic transducer ultrasonic sonochemistry machine is to convert the input electric power to mechanical power (ultrasonic) passed out again, and part of consumes very little power. Ultrasonic transducer, to solve the technical problem is to design a great range, wide frequency band of the ultrasonic transducer. Ultrasonic transducer is also called ultrasonic vibrator, also called ultrasonic vibration head, is an indispensable part of the ultrasonic welding machine, as we all know that the characteristics of the ultrasonic transducer? First say about some characteristics of the ultrasonic transducer, piezoelectric ceramic material with high performance, heat resistance, rare earth materials, effectively reduce the calorific value, improve conversion rate, prolong service life, excellent appearance neat, metallic simple sense.
Transducer is composed of shell, ultrasonic cutting machine matching layer, piezoelectric ceramic disc transducer, backing, which leads to the cable and the Cymbal array receiver. Piezoelectric ceramic disc transducer adopts the thickness direction of polarization of the piezoelectric material, PZT - 5 Cymbal array receiver by 8 ~ 16 of Cymbal transducer, of two metal rings and rubber gasket. Range of the present invention is more than 35 m, frequency band width up to 10 KHZ, high-speed mobile remote target can be detected.
Porn ceramic is the feature of low fever, small amplitude, low capacitance, low fever can make ceramic damping is small, long service life, low capacitance can make the circuit easy to match and good stability, small amplitude is shortcomings, display is small liquid level bubble, available liquid level is low.
Large black piece of pottery and porcelain ultrasonic dispersion machine is characterized by fever, amplitude is larger and larger capacitance, fever is ambassador ceramic performance attenuation fast, short service life, capacitance is ambassador circuit not easy match, large amplitude is of advantages, high performance out of liquid level is bubbling, available liquid level is higher.
Ultrasonic transducer is most often used for cleaning or welding, if porn transducer cleaning machine can meet the requirements of cleaning, should give preference to porn transducer, the use of ultrasonic vibration in high temperature liquid board, should be more preferable porn transducer.
