Hot Sales 20KHz Ultrasonic cleaning vibrator transducer For Industrial Cleaning

Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies and convert electrical signals into mechanical vibrations by the piezoelectric effect of the material. Medical ultrasonic transducers (ultrasonic probes) operate in much the same way, and typically contain an electrical energy storage element and a mechanical vibration system inside. When the transducer is used as a transmitter, the electrical oscillating signal sent from the excitation source will cause a change in the electric or magnetic field in the electrical energy storage element of the transducer, which changes the mechanical vibration system of the transducer through some effect. A driving force is generated to cause it to vibrate, thereby propelling the medium in contact with the mechanical vibration system of the transducer to vibrate and radiate sound waves into the medium. The process of receiving sound waves is exactly the opposite. External sound waves act on the vibrating surface of the transducer, causing the mechanical vibration system of the transducer to vibrate, causing an electric field in the energy storage element of the transducer or by some physical effect. The magnetic field changes accordingly, causing the electrical output of the transducer to produce a voltage and current corresponding to the acoustic signal.

To install an ultrasonic oscillator, you must first understand the structure of the ultrasonic oscillator and the working principle of the ultrasonic oscillator. In fact, the ultrasonic oscillator is also called an ultrasonic oscillator.
The ultrasonic vibrator is a device that realizes the mutual conversion of electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the acoustic impedance matching front and rear radiation cover blocks. The ultrasonic vibrator is composed of an ultrasonic transducer and an ultrasonic horn. The ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. The ultrasonic horn is a passive device that does not generate vibration itself. It only transmits the amplitude of the vibration input by the ultrasonic transducer before changing it. Impedance transformation.

Installation steps and preparation tools:
1. Preparation tools: argon arc welding, No. 10 hexagon socket wrench, chrome iron tin wire, 2.5 square high temperature wire, 2 * 2.5 cable wire amount, vibrator glue, (wire stripper, casing, cable tie, sand blasting machine, Fittings, etc.).
2. Welding screws: Calculate the arrangement position of the vibrators, weld the screws in the cleaned position, and then clean the surroundings of the screws. Be sure to make them flat to avoid affecting the installation of the vibrators.
3. Glue configuration: Stir the glue evenly according to the specified ratio. (Mirray, Ailuda, 4030 glue is mixed before bonding, KMD398 glue is mixed during the bonding process).
4. Install the vibrating head: apply the glue evenly to the bottom of the ultrasonic vibrator, and twist it gently to squeeze out the air and excess glue between the bottom of the transducer and the contact surface of the cylinder bottom, so that the vibrator is tightly combined with stainless steel as a whole .
5. Curing and solidification: It can be cured by being placed in a place with relatively high room temperature. It can be connected in 4-8 hours. After 24 hours, the test machine can be powered on. The test machine must not be allowed to vibrate.
Notes: 1. Metal-type nail machines can also replace TIG welding. 2. The welding screws must be fully welded, otherwise they will fall off easily. 3. Regarding curing, the temperature should be considered for the length of time, the temperature is low for a long time, the temperature is high, it is faster, it is recommended to operate at room temperature, even if heating, do not overheat, the best is appropriate.
