68KHZ 60W High Frequency Ultrasonic Transducer Power Output For Cleaning Precision Parts

The mechanism of ultrasonic cleaning is to make use of the physical effects such as cavitation, radiation pressure and sound flow in the cleaning liquid. It can exfoliate the machinery produced by the dirt on the cleaning parts, and can also promote the chemical reaction between the cleaning liquid and the dirt, so as to achieve the purpose of cleaning the object. The frequency of the ultrasonic cleaning machine can be selected by 10~500 kHz according to the size and purpose of the cleaning material, generally more than 20~50 kHz. With the increase of the frequency of ultrasonic transducer, Langerhans oscillator, longitudinal oscillator and thickness oscillator can be used. In the miniaturization aspect, radial vibration and flexural vibration are also adopted. Ultrasonic cleaning has become more and more widely used in various industries, agriculture, household equipment, electronics, automobile, rubber, printing, aircraft, food, hospital and medical research.

The transducer uses different piezoelectric materials to explain that:
The black chip is P4 series, which is a medium power emitting material with dual transmitting and receiving characteristics.
With low dielectric loss and high mechanical quality factor, it is mainly used in ultrasonic cleaning, ultrasonic atomization and so on.
The Yellow chip is P8 series, which is a high-power emission material with high mechanical quality factor.

Working principle of broadband ultrasonic vibrator:
Ultrasonic waves are composed of a series of sparse and dense longitudinal waves, which propagate around through the liquid medium. When the sound energy is high enough, in the loose half-cycle, the attraction between the liquid phase molecules is broken, forming a cavitation nucleus. The life of the cavitation nucleus is about 0.1μs. It can generate a local high temperature and high pressure environment of about 4000K and 100MPa at the moment of explosion, and generate a microjet with a speed of about 110m/s and a strong impact. This phenomenon is called ultrasonic cavitation. . The ultrasonic enhancement of the chemical reaction and transmission process is mainly caused by the chemical and mechanical effects of ultrasonic cavitation.

1. Ultrasonic vibrator mainly includes several parts such as shell, acoustic window (matching layer), piezoelectric ceramic disc transducer, backing, lead-out cable, array receiver and so on.
2. Among them, the piezoelectric ceramic disc transducer plays the same role as the general transducer, mainly used to transmit and receive ultrasonic waves; and above the piezoelectric ceramic disc transducer is the Cymbal array receiver, It is mainly composed of lead-out cables, transducers, metal rings and rubber washers. It is used as an ultrasonic receiver to receive the Doppler callback signal generated outside the frequency band of the piezoelectric ceramic disc transducer.
3. The ultrasonic dishwasher vibrator is actually a piezoelectric ceramic with the same frequency as its resonant frequency, which uses the piezoelectric effect of the material to convert electrical energy into mechanical vibration. Generally, ultrasonic waves are first generated by an ultrasonic generator, which is converted into mechanical vibration by an ultrasonic transducer, and then ultrasonic waves can be generated by an ultrasonic deriving device and an ultrasonic receiving device.

Ultrasonic transducer application:
1. Among all the cleaning methods, ultrasonic cleaning is the most efficient and effective one. The reason why ultrasonic cleaning can achieve such an effect is closely related to its unique working principle and cleaning method.
2. We know that in production and life, there are many things that need to be cleaned, and there are many types and links that need to be cleaned, such as: removing contaminants from objects, dredging small holes, and common manual cleaning methods for special-shaped objects and hidden parts of objects. Undoubtedly, it cannot meet the requirements. Even steam cleaning and high-pressure water jet cleaning cannot meet the higher cleanliness requirements. Ultrasonic cleaning can also kill bacteria, dissolve organic pollutants, and prevent over-corrosion. Therefore, ultrasonic cleaning Is increasingly widely used in all walks of life:
(1) Machinery industry: removal of anti-rust grease; cleaning of measuring tools; degreasing and rust removal of mechanical parts; cleaning of engines, carburetors and auto parts; dredging and cleaning of filters and screens, etc.
(2) Surface treatment industry: degreasing and rust removal before electroplating; cleaning before ion plating; phosphating treatment; removing carbon deposits; removing oxide scale; removing polishing paste; surface activation treatment of metal workpieces, etc.
(3) Instrumentation industry: high cleanliness of precision parts, cleaning before assembly, etc.
(4) Electronic industry: Removal of rosin and solder spots on printed circuit boards; cleaning of mechanical and electronic parts such as high voltage contacts.
(5) Medical industry: cleaning, disinfection, sterilization of medical equipment, cleaning of laboratory utensils, etc.
(6) Semiconductor industry: high cleanliness cleaning of semiconductor wafers.
(7) Watch first and decoration industry: remove sludge, dust, oxide layer, polishing paste, etc.
(8) Chemical and biological industries: cleaning and descaling of laboratory utensils.
(9) Optical industry: degreasing, sweating and dust removal of optical devices.
(10) Textile printing and dyeing industry: cleaning textile spindles, spinnerets, etc.
(11) Petrochemical industry: cleaning and dredging of metal filters, cleaning of chemical containers, exchangers, etc.
