產品概述 Description

  脈沖噴吹控制儀是脈沖袋式除塵器噴吹清灰系統的主要控制裝置。它的輸出驅動電磁脈沖閥，進而控制壓縮空氣對濾袋循序噴吹清灰，使除塵器的運行阻力保持在設定的范圍內，以保證除塵器的處理能力和收塵效率。

  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.

    控制儀每次輸出一位的驅動電壓，一個驅動電壓持續時間，稱為脈沖寬

度。相鄰二個輸出驅動電壓之間的間隔時間，稱為脈沖間隔。控制儀完成對

所有位的電磁閥驅動輸出所需要的時間，稱為脈沖周期。兩個脈沖周期之間

的停頓時間，稱為循環間隔。

  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.

  根據除塵器的清灰要求設定控制儀的循環間隔、脈沖間隔和脈沖寬度參

數，保證除塵器運行阻力在設定的范圍內。

  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.
