Product Description Ultrasonic oscillator principle:1. The piezoelectric element and the internal electrode are alternately stacked in the ultrasonic vibrator, and have an external electrode that is electrically connected to the internal electrode;The ultrasonic transducer includes an internal electrode group that is substantially divided into four portions along a second direction and a third direction orthogonal to a lamination direction as the first direction, and a first external electrode group and a second external electrode group respectively The electrode group is turned on; by applying an alternating voltage to the first external electrode group and the second external electrode group, the longitudinal vibration mode in which the main vibration occurs in the second direction and the main vibration are in the third direction a bending vibration mode that occurs, thereby generating ultrasonic elliptical vibration;The ultrasonic transducer includes a conductor film for electrode connection formed along a surface perpendicular to the stacking direction, and predetermined predetermined external electrodes of the first external electrode group and the second external electrode group The external electrodes are electrically connected. A device that converts electrical energy and acoustic energy by piezoelectric effect is called a piezoelectric transducer. The ultrasonic transducer provided by the company uses self-produced high-quality piezoelectric ceramic components, which are carefully designed, processed and tested to be bolts. The fastening type produces stable ultrasonic waves even when the load changes. It has the characteristics of large amplitude, high electroacoustic conversion rate, low heat generation, high reliability and good consistency.Ultrasonic Transducer classification:A. piezoelectric chip classification: Black chip P4 series and yellow chip P8 series;B. Frequency classification: low frequency series (17-23KHz), intermediate frequency series (25-28KHz), medium and high frequency series (33-60KHz) and high frequency series (68-200KHz);C. Power classification: 30W series (including 35W), 50W series (including 60W), 100W series (including 80W) and other unconventional power;D. shape classification: straight column and horn typeUltrasonic Transducer Frequency selection :The frequency of the transducer is inversely proportional to the wavelength, and the wavelength is related to the diameter of the cavity (strictly speaking, the nucleation time is longer due to the low frequency), and the diameter of the cavity is related to the explosion pressure. The higher the general frequency, the smaller the wavelength, the smaller the diameter of the cavity, the lower the explosion pressure, but the higher the density of the cavity, the better the permeability.Based on the above principles:Low frequency (17 ~ 23KHz): When the dirt of the cleaned material is heavy or difficult to be cleaned, and the explosive impact does not cause much damage to the surface of the cleaned material, the low frequency series transducer should be selected. Commonly used industries are: magnetic industry, steam protection industry, textile industry and so on. Note that the noise of this series is large, preferably sound insulation.Medium frequency (25 ~ 28KHz): If the dirt of the cleaned material is slightly heavy or the cleaning is difficult and moderate, and the explosive impact does not cause much damage to the surface of the cleaned material, the intermediate frequency series transducer should be selected. This series of industries are the most widely used, and are common in machinery processing industry, electroplating industry, catering industry and so on.Medium and high frequency (33 ~ 60KHz): When the dirt of the cleaned material is light, the cleaning is easy, or the explosive shock damage to the surface of the cleaned material is required, the medium and high frequency series transducer should be selected. Commonly used industries include precision parts, glass glasses, electronic components, circuit boards, etc.High Frequency (68-200KHz): The dirt is very light and easy to clean. When the explosive impact is prohibited to damage the surface of the cleaned object, the high frequency series transducer should be selected. Commonly used industries are semiconductors, special high-precision parts, etc.Ultrasonic vibrator features:1. High performance: high mechanical Q value, high conversion efficiency and excellent quality;2. The ultrasonic vibrator transducer has large amplitude and superior performance;3. Ultrasonic vibrator transducer heat resistance: Piezoelectric ceramic material has good heat resistance, can expand the operating temperature range, and has high Q value, small resonance impedance and small heat generation;4. The ultrasonic vibrator transducer has a neat appearance, no rust, no obvious depressions and scratches.Ultrasonic transducer application:1. Among all cleaning methods, ultrasonic cleaning is the most efficient and effective one. The reason why ultrasonic cleaning can achieve such results is closely related to its unique working principle and cleaning method.2. We know that there are many things that need to be cleaned in production and life. There are many types and links that need to be cleaned, such as: removing pollutants from objects, dredging small holes, common manual cleaning methods for shaped objects and hidden objects. Undoubtedly can not meet the requirements, even the steam cleaning and high-pressure water jet cleaning can not meet the demand for higher cleanliness, ultrasonic cleaning can also kill bacteria, dissolve organic pollutants, prevent over-corrosion, etc., therefore, ultrasonic cleaning It is increasingly used in all walks of life:(1) Machinery industry: removal of rust-proof grease; cleaning of measuring tools; degreasing and derusting of mechanical parts; cleaning of engine, carburetor and auto parts; cleaning and cleaning of filters and filters.(2) Surface treatment industry: degreasing and derusting before electroplating; pre-ion plating cleaning; phosphating; removing carbon deposits; removing scale; removing polishing paste;(3) Instrumentation industry: high cleanliness of precision parts, cleaning before assembly, etc.(4) Electronics industry: printing circuit boards except rosin, solder spots; cleaning of mechanical and electronic parts such as high-voltage contacts.(5) Medical industry: cleaning, disinfection, sterilization of medical equipment, cleaning of experimental utensils, etc.(6) Semiconductor industry: high cleanliness cleaning of semiconductor wafers.(7) Watch and watch industry: remove the sludge, dust, oxide layer, polishing paste, etc.(8) Chemical and biological industries: cleaning and descaling of experimental vessels.(9) Optical industry: degreasing, de-sweating, cleaning, etc. of optical devices.(10) Textile printing and dyeing industry: cleaning textile spindles, spinnerets, etc.(11) Petrochemical industry: cleaning and unblocking of metal filters, cleaning of chemical containers and exchangers, etc. Specification List ModelFrequency CapacitanceResonanceImpedance Size Power Insulation resistance(KHz)(pF)(Ω) Radiation head*Height (mm)(W)(2500VDC)OKS-8QXHNQ-3828/4028/40±1.03800±10%≤30Ω65*7060w≥100MΩOKS-8QXHNQ-2540/13040/130±2.03100±10%≤30Ω25*5820w≥100MΩOKS-4QXHNQ-3840/6838/66±2.04800±10%≤20Ω50*6550w≥100MΩOKS-4QXHNQ-3840/80/13038/79/128±2.04200±10%≤25Ω40*5460w≥100MΩOKS-4QXHNQ-3840/60/8038/65/84±2.04800±10%≤25Ω40*5460w≥100MΩOKS-8QXHNQ-5020/40/6020/40/60±2.05200±10%≤25Ω78*94120w≥100MΩOKS-4QXHNQ-3840/100/16038/100/160±2.04800±10%≤25Ω40*5760w≥100MΩScrew hole size (diameter * pitch * depth)M10*1.0*10
