Through the condensate pump and treatment of typical failure analysis described as similar to the feed pump failure analysis and processing for reference. KEY WORDS： power plant boiler, condensate pump, failure analysis, Treatment 3 目錄 摘 要 ...................................... 1 ABSTRACT ...................................... 2 目錄 .......................................... 3 第一章 泵的基本概念及其結(jié)構(gòu) ...................... 5 泵的定義和分類 ................................ 5 泵的類型 ..................................... 6 泵的用途 ..................................... 8 第二章 泵的基本參數(shù) ............................. 9 基本參數(shù) ..................................... 9 泵的特性曲線 ................................. 11 第三章 汽蝕 ................................... 12 泵的汽蝕 .................................... 12 汽蝕的發(fā)生過程 ............................... 13 泵產(chǎn)生汽蝕時(shí)的現(xiàn)象 ............................ 14 4 第四章 凝結(jié)水泵的故障及其分析 ................... 15 凝結(jié)水泵的使用保養(yǎng) ............................ 15 第五章 凝結(jié)水泵試運(yùn)方案 ......................... 16 試運(yùn)目的 .................................... 16 試運(yùn)應(yīng)具備的條件 ............................. 17 試運(yùn)方法及步驟 ............................... 17 第六章 實(shí)例 ................................... 22 事故經(jīng)過 .................................... 22 凝泵運(yùn)行工況的特點(diǎn) ............................ 23 凝結(jié)水泵存在失壓的因素 ........................ 24 凝結(jié)水泵失壓事故的原因分析 ..................... 25 處理措施 .................................... 27 預(yù)防措施 .................................... 28 參考文獻(xiàn) ..................................... 29 致 謝 ................................
