系统简介(System introduction)


   气垫式流浆箱在满足中高速纸机生产需要改善横幅定量效果显著,其控制系统主要是总压头与液位控制。

  Air cushioned headbox of high speed paper machine production to improve the quantitative effect to meet the banner, the control system is mainly the total head and liquid level control.

  变频技术已在造纸行业大量推广应用,在上述流浆箱控制系统中,通过变频器控制上浆泵转速达到控制流浆箱液位的目的,流浆箱液位也可通过控制上浆泵回流量大小来实现。

  Variable frequency technology has been widely applied in papermaking industry, in the headbox control system, to control the headbox level through the control of frequency converter pump speed, flow slurry tank level can be achieved by controlling the pump to flow.

  系统采用西门子S7系列PLC作为主控部件来完成全部控制功能。

  The system uses S7 series PLC as the main control Siemens components to complete the control function.


2、技术性能(technical performance
 工艺流程:实时显示带控制点的工艺流程以及相关的工艺参数设定   值、测量值、采样值、输出值。轻触车速按钮,即可设置当前车速,系统自动根据车速总压表确认当前总压设定值并加以控制。

  Process: real time display of process control and process parameter setting, measurement, sampling value, output value. Touch the button to set the current speed, speed, the system automatically according to the speed of the total pressure table confirm current total pressure setting and control.


  实时曲线:以曲线方式实时显示总压、液位的测量值、设定值,刷新时间可在线修改。

  Real time curve: the curve of real-time display measuring total pressure and liquid level value and the set value, the refresh time can be modified online.
 历史查询:可连续查询一个月的工况记录并用曲线显示。

  Query: query a month of continuous operation record and curve display.
  参数设置:可分为工艺参数设置和控制参数设置两类
  Parameter settings: settings and control parameter settings can be divided into two types as parameters
