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.

DMK-5CSA 型脉冲喷吹控制仪具备如下功能：
The following are the functions of DMK-5CSA Pulse
Jet Control Device:
可根据清灰要求，调整循环间隔、脉冲间隔和脉冲宽度，控制电磁脉冲阀的开启和关闭，对
1 除尘器实行定时清灰。同时设有压差控制仪输入接点，接上压差控制仪后可以定压差清灰。
According to dust-cleaning requirement, cycle interval, pulse interval and pulse width can be
adjusted, to control turning on or off the electromagnetic pulse valve, and to clean dust in the
bag house at a fixed time. Meanwhile, there is differential pressure to control the input
connection point of the control device. When differential pressure of control device is
connected, differential pressure can be set to clean dust at a fixed pressure.
