Operation principle of the present invention:
While carrying out work, the working fluid that pressure is higher enters in nozzle 2 by Working-fluid intaking joint 2, the ultrasonic cavitation effect increasing temperature and pressure that working fluid sends by supersonic generator 12, and by nozzle, pressure energy is converted into kinetic energy, form supersonic jet, be sucked fluid---driving fluid due to and working fluid between extremely strong shear action and being entrainmented in uiform section mixing chamber 5 by injection; High while making the temperature and pressure of working fluid enter into nozzle than just due to hyperacoustic cavitation, and because hyperacoustic direction propagation effect, working fluid and driving fluid are entrainmenting in chamber 3 approximate isobaric mixing, two fluid streams generation quality, momentum and energy exchange, so the speed of working fluid constantly reduces, and be sucked, medium---the speed of driving fluid constantly increases, and consistent gradually at mixing section, thereby form single uniform fluid-mixing, kinetic transformation in diffusion chamber 6 becomes pressure energy, after fluid-mixing deceleration supercharging, discharges injector.
Produced the signal of a CF by supersonic generator, this signal can be sinusoidal signal, also can be pulse signal, this CF is exactly the frequency of ultrasonic transducer, and the ultrasonic frequency generally using in ultrasonic equipment is 25KHz, 28KHz, 35KHz, 40KHz; Ultrasonic transducer is the device that converts electric energy to mechanical energy (ultrasonic wave), and wherein mature and reliable is to realize with piezo-electric effect the device that electric energy and acoustic energy are changed mutually, is called PZT (piezoelectric transducer).PZT (piezoelectric transducer) is generally made up of central piezo ceramic element, front and back metal cover board, prestressing force screw rod, electrode slice, insulation tube, and its main feature is that efficiency is high: Qm is high, can obtain high electro-acoustic conversion efficiency in resonant frequency point work; Amplitude is large: vibration velocity is than high, and front shroud amplitude is large, exerts oneself large 25% than common transducer; Good stability: under normal use, the transducer life-span is more than 20000 hours; Good heat resistance: resonance impedance is little, caloric value is little, serviceability temperature scope is wide.Ultrasonic wave refers to that frequency is higher than 20kHz, the general inaudible sound wave of people's ear, it is the main mechanical oscillation that produces two kinds of forms in medium, be swaying (shear wave) and lengthwise oscillations (compressional wave), the former can only produce in solid, the latter can produce in solid, liquid, gas body, and here we use compressional wave.Because ultrasonic frequency is high, wavelength is short, thereby directionality good (frequency is higher, directionality better), energy large (E=h*f ultrasonic energy E frequency f Planck coefficient h), penetration power are strong etc.Ultrasonic cavitation effect refers to that the micro-gas core (cavitation bubble) being present in liquid or gas vibrates under the effect of sound wave, the growth occurring in the time that sound wave reaches certain value and the dynamic process of collapse.Cavitation generally comprises three phases: the formation of cavitation bubble, grow up and violent collapse.
