Ultrasonic emulsification machine pneumatic control equipment, ultrasonic sonochemistry machine welding products can be adjusted according to need of pressure, usually 0.3 0.7 MPa (no more than 0.8 MPa).
Ultrasonic emulsification machine has brought the intake throttle valve. Low air pressure equipment can't run, too much pressure can crushed plastic parts.
Ultrasonic emulsification machine pneumatic components including governor, pressure adjusting knob. Ultrasonic emulsification machine speed governor used to regulate the speed of upper and lower to the cylinder. Ultrasonic emulsification machine air pressure adjustment knob adjustment work
How much pressure is required for ultrasonic emulsification?
Different plastic materials determines the size of need when welding pressure, choose a suitable size of pressure value for welding results have very important influence.
Welding pressure is too low, can lead to ultrasonic vibration is passed to the welding parts, well lead to welding with welding surface friction between shortage, energy will be a large part of the above the surface of sliding, eventually lead to poor welding
Pressure is too high, can lead to the use of vibration ultrasonic dispersion machine energy is not reasonable, the friction force is too large, welding pieces of the friction between motion decreases, and even affect the amplitude of the situation, the result is the connection between the area of the weldment doesn't increase instead of decrease, solder joint strength will decline.
Ultrasonic emulsification choose the size of the pressure, can according to the melting point of high and low melting point (the higher the pressure value is larger), according to the plastic parts size (size, the greater the pressure the greater the value).
Sound intensity refers to the intensity of the sound energy ultrasonic dispersing machine flow and the direction of the vector. Sound intensity is the size of the sound field of a certain unit of time in vertical direction of the particle velocity of sound energy per unit area. Sound intensity measuring instrument is a kind of sound intensity measurement of air medium in the axis of the probe of the instrument. Near the sound source can be got through multipoint sound intensity measurement, sound energy flow intensity distribution of a plane, the radiation characteristics of the sound source. Sound source of the sound power level can be measured by sound intensity measurement.
Sound intensity measuring instrument consists of two parts, sound intensity probe and strong processor, sound intensity probe USES a pair of sound pressure microphone at intervals. Sound intensity measuring instrument should give strong noise and acoustic pressure octave or 1/3 octave spectrum, and provide A weighting function. Sound intensity meter, there are two precision level: level 1 and level 2, the requirement of grade 1 is more strict than level 2. In the use of the sound intensity meter, usually using sound intensity calibrator for the calibration. On the sound intensity probe two microphone calibrator model acoustic pressure and phase difference, usually used with a sound intensity probe. Because this is a kind of simulation method, calibrator simulation need separate checks the accuracy of the sound intensity.
