农药静电喷雾液滴直径和荷电量的测量装置

Measuring Apparatus for Diameter & Charge of Droplets in Electrostatic Pesticide Spraying

用正弦交变电场法测量液滴的直径和荷电量的方法是根据荷电液滴在正弦电场中受电场力、重力、空气的浮力及斯托克斯力的作用,液滴的运动轨迹是一条正弦曲线,测出正弦曲线的振幅和波长,就可以计算出液滴的直径和荷电量。

Measuring the diameter and charge of a droplet by using sine alternating current field is based on that the path of charged droplet, which affected by electric force,gravity, floatage of air and Stokes force in sine wave field, is a sine curve, and the diameter and charge of the droplet can be found out by measuring the amplitude and wave length of the sine curve.
