對于各個電廠來說,控制系統(tǒng)的可靠性對整個電廠的安全可靠性是生死攸關(guān)的,如何盡可能的提高DCS的可靠性,從而保證電力生產(chǎn)的安全和經(jīng)濟(jì)已成為一項(xiàng)越來越重要的工作。本文作者根據(jù)自己在電廠從事熱控檢修工作的經(jīng)驗(yàn),從DCS控制系統(tǒng)角度,從控制系統(tǒng)選型、設(shè)備安裝、程序設(shè)計和調(diào)試驗(yàn)收以及技術(shù)培訓(xùn)等方面,就如何提高整個DCS的可靠性進(jìn)行了闡述。
1、DCS控制系統(tǒng)選型
不論在新建機(jī)組還是老機(jī)組進(jìn)行的控制系統(tǒng)改造,均面臨著盡可能質(zhì)優(yōu)價廉地選擇理想的控制系統(tǒng)的問題。在此,我們姑且撇開控制系統(tǒng)的價格,僅從提高可靠性要的角度來考慮,在DCS選型過程中需要注意以下各方面的問題:
(1)在選擇DCS控制系統(tǒng)時要優(yōu)先考慮有在類似機(jī)組上良好運(yùn)行業(yè)績的控制系統(tǒng),這樣的控制系統(tǒng)通過了工廠試驗(yàn)和實(shí)際投運(yùn),其可靠性得到了時間的檢驗(yàn)。

轉(zhuǎn)子流量計在工業(yè)生產(chǎn)過程中應(yīng)用較廣,可以測量多種介質(zhì)的流量,特別適用于中小管徑和低雷諾數(shù)的中小流量測量。轉(zhuǎn)子流量計結(jié)構(gòu)簡單,靈敏度高,量程比寬(10:1),壓力損失小且恒定,對直管段的要求不高,刻度近似線性,價格便宜,使用維護(hù)簡便。但儀表受被測介質(zhì)密度、粘度、溫度、壓力等因素的影響,其精度一般在1.5級左右。
