為了保證污水處理廠處理過(guò)程的安全性，可靠性和生產(chǎn)的連續(xù)性，提高污水處理廠，自動(dòng)化控制柜控制系統(tǒng)采用目前國(guó)內(nèi)外污水處理廠廣泛應(yīng)用并取得良好效果的基于可編程序控制器PLC的集散型控制系統(tǒng)，并以各種儀表及計(jì)算機(jī)監(jiān)控系統(tǒng)組成監(jiān)控和數(shù)據(jù)的采集（SCADA）系統(tǒng)。集散型控制系統(tǒng)的特點(diǎn)是將管理層和控制層分開。管理屋主要是對(duì)全廠整個(gè)生產(chǎn)過(guò)程進(jìn)行監(jiān)視；電氣控制柜廠家控制層主要是通過(guò)現(xiàn)場(chǎng)PLC完成各自轄域內(nèi)的自動(dòng)控制。SCADA系統(tǒng)可理解為通過(guò)現(xiàn)場(chǎng)檢測(cè)儀表和網(wǎng)絡(luò)設(shè)備完成對(duì)主要工藝流程的監(jiān)控和對(duì)生產(chǎn)過(guò)程的工藝參數(shù)進(jìn)行數(shù)據(jù)采集，淄博不銹鋼控制柜推薦廠家，淄博不銹鋼控制柜推薦廠家。污水處理廠自控系統(tǒng)通常由污水廠與廠外泵站兩部分組成，淄博不銹鋼控制柜推薦廠家。污水處理自動(dòng)化系統(tǒng)的是監(jiān)控系統(tǒng)的PLC與通訊網(wǎng)絡(luò)，其性能對(duì)于污水處理自動(dòng)化系統(tǒng)具有決定性作用，PLC與通訊網(wǎng)絡(luò)的選擇要符合污水處理自動(dòng)化實(shí)際監(jiān)控需求，這是確保污水處理自動(dòng)化系統(tǒng)性能的關(guān)鍵。淄博不銹鋼控制柜推薦廠家</p><div

PLC控制柜在很多領(lǐng)域中都有應(yīng)用，這也推動(dòng)了PLC控制柜供應(yīng)商的發(fā)展?；蛟S有很多人并不是很了解控制柜具體的應(yīng)用領(lǐng)域，也不知道它適合在什么環(huán)境下被使用，電氣控制柜廠家就來(lái)詳細(xì)了解一下這兩個(gè)方面的內(nèi)容。首先，我們先來(lái)看看控制柜的應(yīng)用領(lǐng)域，一般在以下五大領(lǐng)域中應(yīng)用的范圍比較廣：1.開關(guān)量邏輯控制取代傳統(tǒng)的繼電器電路，實(shí)現(xiàn)邏輯控制、順序控制，既可用于單臺(tái)設(shè)備的控制，也可用于多機(jī)群控及自動(dòng)化流水線。如注塑機(jī)、印刷機(jī)、訂書機(jī)械、組合機(jī)床、磨床、包裝生產(chǎn)線、電鍍流水線等。2.工業(yè)過(guò)程控制在工業(yè)生產(chǎn)過(guò)程當(dāng)中，存在一些如溫度、壓力、流量、液位和速度等連續(xù)變化的量(即模擬量)，PLC控制柜采用相應(yīng)的A/D和D/A轉(zhuǎn)換模塊及各種各樣的控制算法程序來(lái)處理模擬量，完成閉環(huán)控制。過(guò)程控制在冶金、化工、熱處理、鍋爐控制等場(chǎng)合有非常的應(yīng)用。3.運(yùn)動(dòng)控制PLC控制柜可以用于圓周運(yùn)動(dòng)或直線運(yùn)動(dòng)的控制。一般使用**的運(yùn)動(dòng)控制模塊，如可驅(qū)動(dòng)步進(jìn)電機(jī)或伺服電機(jī)的單軸或多軸位置控制模塊，用于各種機(jī)械、機(jī)床、機(jī)器人等場(chǎng)合。4.數(shù)據(jù)處理PLC控制柜供應(yīng)商的產(chǎn)品具有數(shù)學(xué)運(yùn)算(含矩陣運(yùn)算、函數(shù)運(yùn)算、邏輯運(yùn)算)、數(shù)據(jù)傳送、數(shù)據(jù)轉(zhuǎn)換、排序、查表、位操作等功能。淄博不銹鋼控制柜推薦廠家</p><div

可控硅型優(yōu)點(diǎn)是無(wú)觸點(diǎn)、具有交流負(fù)載特性，負(fù)載能力不大。繼電器輸出具有交直流負(fù)載特點(diǎn)，負(fù)載能力大。常規(guī)控制中一般首先選用繼電器觸點(diǎn)型輸出，缺點(diǎn)是開關(guān)速度慢，一般在10ms左右，不適于高頻開關(guān)應(yīng)用。三、接地問(wèn)題自動(dòng)化控制柜系統(tǒng)接地要求比較嚴(yán)格，要有**的**接地系統(tǒng)，還要注意與控制柜有關(guān)的其他設(shè)備也要可靠接地。多個(gè)電路接地點(diǎn)連接在一起時(shí)，會(huì)產(chǎn)生意想不到的電流，導(dǎo)致邏輯錯(cuò)誤或損壞電路。而產(chǎn)生不同的接地電勢(shì)的原因，通常是由于接地點(diǎn)在物理區(qū)域上被分隔的太遠(yuǎn)，當(dāng)相距很遠(yuǎn)的設(shè)備被通信電纜或傳感器連接在一起的時(shí)候，電纜線和地之間的電流就會(huì)流經(jīng)整個(gè)電路，即使在很短的距離內(nèi)，大型設(shè)備的負(fù)載電流也可以在其與地電勢(shì)之間產(chǎn)生變化，或者通過(guò)電磁作用直接產(chǎn)生不可預(yù)知的電流。在不正確的接地點(diǎn)的電源之間，電路中有可能產(chǎn)生毀滅性的電流，以至于破壞設(shè)備。自動(dòng)化控制柜系統(tǒng)一般選用一點(diǎn)接地方式。為了提高抗共模干擾能力，對(duì)于模擬信號(hào)可以采用屏蔽浮地技術(shù)，即信號(hào)電纜的屏蔽層一點(diǎn)接地，信號(hào)回路浮空，與大地絕緣電阻應(yīng)不小于50MΩ。四、消除線間電容避免誤動(dòng)作電纜的各導(dǎo)線間都存在電容，合格的電纜能把此容值限制在一定范圍之內(nèi)。</p><p> 變頻控制柜系統(tǒng)中的變頻調(diào)速能夠應(yīng)用在大部分的電機(jī)拖動(dòng)場(chǎng)合，由于它能提供準(zhǔn)確的速度控制，因此可以方便地控制機(jī)械傳動(dòng)的上升、下降和變速運(yùn)行。變頻應(yīng)用可以地提高工藝的效率(變速不依賴于機(jī)械部分)，同時(shí)可以比原來(lái)的定速運(yùn)行電機(jī)更加節(jié)能。下面例舉使用變頻調(diào)速的10個(gè)理由，來(lái)說(shuō)明變頻器應(yīng)用日趨普及的基本認(rèn)識(shí):(1)控制電機(jī)的啟動(dòng)電流。當(dāng)電機(jī)通過(guò)工頻直接啟動(dòng)時(shí)，它將會(huì)產(chǎn)生7到8倍的電機(jī)額定電流。這個(gè)電流值將增加電機(jī)繞組的電應(yīng)力并產(chǎn)生熱量，從而降低電機(jī)的壽命。而變頻調(diào)速則可以在零速零電壓?jiǎn)?dòng)(也可適當(dāng)加轉(zhuǎn)矩提升)。一旦頻率和電壓的關(guān)系建立，變頻器就可以按照V/F或矢量控制方式帶動(dòng)負(fù)載進(jìn)行工作。使用變頻調(diào)速能充分降低啟動(dòng)電流，提高繞組承受力，用戶直接的好處就是電機(jī)的維護(hù)成本將進(jìn)一步降低、電機(jī)的壽命則相應(yīng)增加。(2)降低電力線路電壓波動(dòng)。在電機(jī)工頻啟動(dòng)時(shí)，電流劇增的同時(shí)，電壓也會(huì)大幅度波動(dòng)，電壓下降的幅度將取決于啟動(dòng)電機(jī)的功率大小和配電網(wǎng)的容量。電壓下降將會(huì)導(dǎo)致同一供電網(wǎng)絡(luò)中的電壓敏感設(shè)備故障跳閘或工作異常，如PC機(jī)、傳感器、接近開關(guān)和接觸器等均會(huì)動(dòng)作出錯(cuò)。而采用變頻調(diào)速后，由于能在零頻零壓時(shí)逐步啟動(dòng)。</p><div

style="text-indent:25px">變頻器接線規(guī)范如下：1.信號(hào)線與動(dòng)力線必須分開走線：使用模擬量信號(hào)進(jìn)行遠(yuǎn)程控制變頻器時(shí)，為了減少模擬量受來(lái)自變頻器和其它設(shè)備的干擾，請(qǐng)將控制變頻器的信號(hào)線與強(qiáng)電回路（主回路及順控回路）分開走線，注意應(yīng)保持30cm以上的距離。2.信號(hào)線與動(dòng)力線必須分別放置在不同的金屬管道或者金屬軟管內(nèi)部：連接PLC和變頻器的信號(hào)線如果不放置在金屬管道內(nèi)，極易受到變頻器和外部設(shè)備的干擾；同時(shí)由于變頻器無(wú)內(nèi)置的電抗器，所以變頻器的輸入和輸出級(jí)動(dòng)力線對(duì)外部會(huì)產(chǎn)生極強(qiáng)的干擾，因此放置信號(hào)線的金屬管或金屬軟管一直要延伸到變頻器的控制端子處，以保證信號(hào)線與動(dòng)力線的徹底分開，這有這樣變頻柜才能確保變頻器的安全。請(qǐng)大家一定注意這些規(guī)范。防止出現(xiàn)問(wèn)題。淄博不銹鋼控制柜推薦廠家</p><p
