An engineer case is introduced, which is about " the reconstruction of high voltage fan ' s speed - adjusting by frequency conversion and the design of plc ( programmable logic controller ) control system in shui cheng iron and steel company ". in this project, an advanced controlling technology, based on the method in this paper, is used to realize the closed loop control of discharge header pressure of two coke ovens
介紹「水鋼煤焦化公司鼓風機高壓變頻調速及系統plc控制改造」的工程概況,對煤氣鼓風機採用先進的變頻調速技術和計算機控制技術進行改造,實現對兩座焦爐集氣管壓力自動調節的閉環控制功能,既滿足了煤氣量的自動調節的要求,又避免了煤氣鼓風機出口閥門的節流調節,節能效果相當可觀。Based on the experience of regulating frequency according to different valve ' s angle, a reasonable controlling tactic is proposed. when the situation changes to a small degree, electromotor makes fan running at a constant rate ; when the situation changes to the limiting range, the discharge header pressure is automatically adjusted by the rate of fan
制定合理的控制策略,採用基於閥門開度的變頻調節策略,即工況變化較小的情況下,電機帶動鼓風機恆速運行,通過控制閥門開度自動調節集氣管壓力;當閥門開度到達極限值,還不能達到控制要求時,再通過變頻器改變鼓風機轉速,以自動調節集氣管壓力。The work here has a lot of application and stringency. for the first time, the various ventilating methods and effects to control the smoke in a fire emergency of the erlang mountain tunnel semi - transient ventilation road tunnel are presented. with the hypothesis of one - dimensional steady ideal fluid, the experimental and numerical studies are presented
本文首次研究了半橫向通風方式的隧道在發生火災時,通過通風系統的風機、橫通道及平行導洞內的閥門的不同動作方式在著火點產生大於臨界風速的強制氣流,對隧道內煙氣走向進行控制的各種方法和效果。
