    • An electrostatic spray device that maintains a consistent charge-to-mass ratio in order to maintain a consistent target spray quality is disclosed. During steady state conditions, the high voltage power supply adjusts the output voltage level in response to changing environmental and/or operating conditions. During transient conditions such as start-up, shut-down and changing flow rate conditions, the high voltage power supply ensures that the charge-to-mass ratio is maintained. During, start-up, for example, the high voltage power supply charges the high voltage electrode to a predetermined voltage level before the product is delivered to the charging location. During shut-down, the product delivery is stopped before the high voltage power supply shuts off power to the high voltage electrode, and during changes in product flow rate, the voltage level of the high voltage electrode is adjusted to maintain a consistent charge-to-mass ratio. The present invention also prevents afterspray by discharging the stored charge remaining in storage elements of the high voltage power supply.
    • 公开了一种保持一致的电荷质量比以便保持一致的目标喷雾质量的静电喷涂装置。 在稳态条件下,高压电源根据不断变化的环境和/或工作条件调整输出电压电平。 在诸如启动,关闭和流量条件变化的瞬态条件下,高压电源确保了电荷质量比得以保持。 例如,在启动期间,高压电源在产品被传送到充电位置之前将高电压电极充电到预定的电压电平。 在停机期间,在高压电源关闭高压电极的电源之前,产品交付停止,并且在产品流量变化期间,调节​​高压电极的电压电平以保持一致的电荷 - 比例 本发明还通过放电剩余在高压电源的存储元件中的储存电荷来防止喷射。
