摘　　要：针对目前大型火力发电厂生产过程中,汽机疏水系统常见的几种缺陷形式进行归纳、概括,制订对策,开发出了针对疏水阀运行情况的实时监视系统,提出了判断运行中疏水门是否泄漏的方法和思路,为及时发现疏水系统缺陷,进行预防性检修提供了依据,从而大大提高了机组运行的安全性和经济性。Study on main defects of turbine drain system inducing, generalizing and establishing countermeasures in current thermal power plant production process, with a real-time operating condition monitor system of drain valve was developed. A method to judge if leakage exist in a running drain valve was established, which detect drain system defect in time and provide basis to preventive examination and repair, so that security and economy of unit operation was improved greatly.
