主風(fēng)機(jī)組根據(jù)總管流量關(guān)小防喘閥，備風(fēng)機(jī)組自動逐漸根據(jù)總管流量打開防喘閥。
5、直至備風(fēng)機(jī)組出口單向閥關(guān)閉或者程序自動指示備機(jī)切出裝置。
6、HMI自動彈出主備機(jī)切機(jī)完成指示，操作工首先點(diǎn)擊取消切機(jī)，然后操作工需要到現(xiàn)場把備風(fēng)機(jī)組出口電動閥手動關(guān)閉，最后手動可以把備風(fēng)機(jī)切入安全運(yùn)行狀態(tài)。
5.切機(jī)運(yùn)行效果分析CI858以太網(wǎng)接口模塊
圖5-1主風(fēng)機(jī)組切入系統(tǒng)工藝趨勢
由圖5-1所示，各曲線含義分析如下：
白色曲線是主風(fēng)機(jī)組防喘閥的輸出曲線，在緩慢關(guān)閉；
藍(lán)色曲線是備風(fēng)機(jī)組防喘閥的輸出曲線，在緩慢打開；
黃色曲線是總管流量的設(shè)定值；
綠色曲線是總管流量的實(shí)測值；
紅色曲線是總管壓力的實(shí)測值；
紫色曲線是主風(fēng)機(jī)組出口排氣壓力值；
淺藍(lán)色曲線是備風(fēng)機(jī)組出口排氣壓力值；
粉色曲線是開始切機(jī)標(biāo)志。
通過以上曲線的走勢可以看出，機(jī)組在切機(jī)過程中，實(shí)際總管壓力及流量均在設(shè)定值附近穩(wěn)定運(yùn)行，表明切機(jī)過程平穩(wěn)無波動。
6.兩器壓差控制過程

由圖4-1所示，分析如下：CI858以太網(wǎng)接口模塊
增設(shè)了調(diào)節(jié)偏差死區(qū)功能，減少了煙機(jī)蝶閥、大小旁通閥頻繁調(diào)節(jié)；
取消了原先設(shè)置的爬坡功能，調(diào)節(jié)更及時有效； PID controller with this. The so-called control can be divided into feedback control and no feedback control. Of course, the PID we discuss has feedback control. The so-called feedback control is nothing more than to participate in the operation to determine the size or direction of the control quantity according to the situation of the controlled quantity. So how to determine the size of the control quantity according to the two controlled quantities? Alas, there are many classifications. The so-called advanced control mode is "advanced" at this point, There are "adaptive control, fuzzy control, predictive control, neural network control, expert intelligent control" and so on (as for the advantages of these control methods, alas, I only used PID, and I can't say anything else. If I go to copy books, it's not convincing, and the key is to be lazy to copy them. If the old brother wants to write a paper, he can give play
