Change the way net-cleaning of the screen:
1, main Copper powder is constantly beating elastic balls prevent occlusion mesh material to reach NET-cleaning purposes. But in the process of using mesh blinding especially serious, indicating that this programme was not obvious, and bouncing the ball bouncing high and difficult to control, easy to create the screen damage.
2, using ultrasound instead of bouncing ball net cleaning device, its basic principle is: ultrasonic vibrating transducer with high frequency electric power generation through transformation in high frequency sinusoidal form of longitudinal oscillations, these oscillations are passed on to the resonator resonator resonance, then by the resonance vibration even transmitted to the screen. Keep the item on the screen remains in a suspended state, inhibits adhesion, friction, pancake and blocking network factors such as reunion, effective screening and net-cleaning purposes.
3, and regulation spin vibration screen heavy hammer angle: regulation heavy hammer of phase angle on can change screen online material of movement track and stay time, phase angle is less than 15 °, powder in screen online stay of time shortest, screening efficiency not high, only applies Yu General General screening; phase angle for 45 °, powder in screen surface Shang stay of time most long, for fine screening; Dang phase angle is greater than 45 °, powder run track tocenter closer, for special screening. Spherical solder powder not only screening accuracy is above 90%, oxygen content not exceeding 0.1 ‰, but also ensuring screening efficiency, so powder on the screen time is not too long and not too short, too short screening efficiency and accuracy are not up to, too much oxygen content.
