变频调速技术在热电联产系统控制中的应用2.1中心换热站及外网控制锅炉系统中主要包括系统恒压补水、系统热水（载体）循环、系统燃烧控制与炉膛压力控制，在热电联产中，它所产生过热蒸汽可以直接输出，也可经过汽水交换后输出热水，蒸汽或热水的热能经过管网中的各个换热站提供给各个热用户。2外网循环泵的控制保证供热系统内的压力恒定是供热系统正常运行的基本前提条件。供热系统的管网通常是封闭的管道系统，从理论上讲，水的消耗量很少。

　　八、电动机过热甚至冒烟
　　故障原因①电源电压过高；②电源电压过低，电动机又带额定负载运行，电流过大使绕组发热；③修理拆除绕组时，采用热拆法不当，烧伤铁芯；④电动机过载或频繁起动；⑤电动机缺相，两相运行；⑥重绕后定于绕组浸漆不充分；⑦环境温度高电动机表面污垢多，或通风道堵塞；
　　故障排除①降低电源电压（如调整供电变压器分接头）；②提高电源电压或换粗供电导线；③检修铁芯，排除故障；④减载；按规定次数控制起动；⑤恢复三相运行；⑥采用二次浸漆及真空浸漆工艺；⑦清洗电动机，改善环境温度，采用降温措施

赤泥中含有大量强碱性化学物质，渗入地下极易造成严重水污染。郭庄泉域面积56平方公里，主要分布在临汾的霍州、汾西、洪洞，晋中的灵石，吕梁的汾阳、孝义、交口等县市。山西省水利厅郭庄泉管理处处长宿辉对记者说，郭庄泉历来是域内农业和居民生活最重要的水源，说郭庄泉是临汾、晋中、吕梁三市的生命泉，一点也不夸张。宿辉对记者说，十多年前，郭庄泉每秒平均流量约七八个立方，但现在已不足以往的四分之一，不少泉眼已经断流。
