應及時進行檢查。排污編輯壓差排污:當雜質聚積到一定數量時,利用冷卻水進管之間差壓來反沖洗排污,即電接點壓力表接通控制,控制機構打開電動排污閥,電動減速機將以每分鐘3-6轉的轉速運轉,經由排污管路和排污閥門冷卻水管中,清排一次約5-10分鐘左右。當出現大的雜物,濾網不能運行到位時,電動裝置應作反方向運行,沖洗雜物。用戶如需要可設置排污時間性,在0-99小時內設定清洗排污時間,一般設置為12個小時排污一次,時間設定可以按照電廠水質的情況而做相應。即設定時間啟動電動減速機進行反轉使排污閥打開,依次進行反轉反沖洗排污。直至全部腔室反沖完畢,電動裝置停止工作,電動反沖閥和電動排污閥關閉。鐵路鐵路燈鐵路分為視覺和聽覺,可以說是有聲有色,多彩。它們是指示列車運行和調車作業的命令,有關行車人員必須嚴格執行。鐵路是人們在實踐中逐步發明和完善的。早期的鐵路開始行車時,是由鐵路職工騎馬在前面引導列車運行。為了醒目,他們帶著禮帽,身穿黑大衣和白色褲子,用揮列車前進或停止。當時鐵路于白天行車,列車很少,速度大約每小時6~16公里,所以由人騎馬來指揮,上沒什么問題。以后,列車對數多了,速度也快了,騎馬已跑不過火車,跟在火車后面打還有什么用?為了確保,人們開始研究固定的設備:用一塊長方形的板子,橫向線路是停車,順向線路是進行。可是順向線路的板子實際上很難看見。
