D  I脉冲喷吹控制仪是脉冲袋式除尘器喷吹清灰系统的主要控制装置。它的输出驱动电磁脉冲阀，进而控制压缩空气对滤袋循序喷吹清灰，使除尘器的运行阻力保持在设定的范围内，以保证除尘器的处理能力和收尘效率。

Pulse jet control device is a main control device in a jet dust-cleaning system of a pulse bag-house. It outputs driving electromagnetic pulse valve, to control compressed air, to jet dust on the filtration bag in a proper sequence, and to keep the operation resistance to clear dust within the set range, so as to guarantee the processing capability and dust-Collection efficiency of the bag house.

控制仪每次输出一位的驱动电压，一个驱动电压持续时间，称为脉冲宽度。相邻二个输出驱动电压之间的间隔时间，称为脉冲间隔。控制仪完成对所有位的电磁阀驱动输出所需要的时间，称为脉冲周期。两个脉冲周期之间的停顿时间，称为循环间隔。

The control device creates driving voltage output every time. One driving voltage has duration, called a pulse width. The interval time between the two interfacing output-driving voltages is called as pulse interval. The time necessary for the control device to complete electromagnetic valve outputs of all bits is called as pulse cycle. Pause time between the two pulse cycles is call as cycle interval.

根据除尘器的清灰要求设定控制仪的循环间隔、脉冲间隔和脉冲宽度参数，保证除尘器运行阻力在设定的范围内。

According to the dust-cleaning requirement of bag house, control device parameters, such as cycle interval, pulse interval and pulse width, are set, to guarantee that the operation resistance of the bag house is within the set range.NG GREEN INDUS
