描述

P0400YD

目前高層建筑在各類城市中比比皆是。為了防止意外火災(zāi),高層建筑一般均設(shè)有消防專用泵組。但是許多設(shè)備都因無專人管理,不能定期試機(jī)運行,天長日久就會導(dǎo)致泵體卡死、銹死,所以經(jīng)常會出現(xiàn)在發(fā)生火災(zāi)時設(shè)備不能充分發(fā)揮作用的情況,造成不應(yīng)有的損失。通常老設(shè)備的啟動/運行轉(zhuǎn)換控制用的是皮碗真空式定時繼電器,其定時時間誤差大,橡膠容易老化破損,維護(hù)不便。電子式定時繼電器也存在類似問題。我們采用OMRON公司的可編程序控制器(PLC)對消防泵組進(jìn)行控制,實現(xiàn)泵組在備用時定期試運行,消防用水時自動啟動。硬件無調(diào)整元件,成本低,可靠性高,維護(hù)方便。而且可以很容易地根據(jù)不同需要進(jìn)行擴(kuò)展。這樣能夠有效地杜絕泵體銹死或消防用水時不能及時加壓的事故。PLC的軟件設(shè)計一般采用梯形圖的形式進(jìn)行編程,直觀且簡單易學(xué)。C系列PLC的指令豐富,提供了48個定時/計數(shù)器供用戶使用,從而給系統(tǒng)設(shè)計帶來了很大的方便。在設(shè)計中,長時間的定時控制若采用多個定時器級連的方式實現(xiàn),雖然直觀,但略顯繁冗。我們在程序中用定時器設(shè)計了一個1分鐘的時鐘作為其他計數(shù)器的輸入,使得長時間的定時設(shè)計更便于實現(xiàn),控制程序也就更加簡潔。在消防用水時為了避免由于水壓波動而導(dǎo)致水泵頻繁起停,我們在程序中采用了“延時濾波”處理,達(dá)到了較好的效果。在為提升水壓而增加后續(xù)水泵時,為了避免同時投入水泵而對電網(wǎng)造成過大的沖擊,也采用了延時的方法,達(dá)到了預(yù)期的目的。我國是世界上少數(shù)幾個以煤為主要能源的國家之一,目前每年煤炭消費量約12億噸,其中80%通過燃燒被利用。然而,燃燒設(shè)備陳舊、效率低、排放無控制造成了能源和環(huán)境污染嚴(yán)重,能源節(jié)約與環(huán)境保護(hù)已成為現(xiàn)有燃煤技術(shù)所需解決的主要問題。我國現(xiàn)有大量的電站鍋爐和供熱鍋爐,每年耗煤量占我國原煤產(chǎn)量的比例相當(dāng)驚人,但大多數(shù)工業(yè)鍋爐處于能耗高、浪費大、環(huán)境污染等嚴(yán)重的生產(chǎn)狀態(tài)。故提高熱效率,降低耗煤量是一件具有深遠(yuǎn)意義的工作。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學(xué)習(xí)編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運算、實數(shù)運算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機(jī)+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會一種至于其它的學(xué)習(xí)起來也就簡單了。
