热力发电厂闭式冷却水系统是一个重要且庞大的系统，为机组辅助设备提供冷却水源，以保证辅助设备及分系统的正常运行。某机组闭式冷却水系统曾发生大量空气窜入现象，导致该系统的闭式冷却水泵工作失常，为此对故障原因进行了详细的排查，找出了输灰空压机后冷却器的冷却水铜管破裂的故障点，解决了空气窜入的问题。
熱力髮電廠閉式冷卻水繫統是一箇重要且龐大的繫統，為機組輔助設備提供冷卻水源，以保證輔助設備及分繫統的正常運行。某機組閉式冷卻水繫統曾髮生大量空氣竄入現象，導緻該繫統的閉式冷卻水泵工作失常，為此對故障原因進行瞭詳細的排查，找齣瞭輸灰空壓機後冷卻器的冷卻水銅管破裂的故障點，解決瞭空氣竄入的問題。

Closed cooling water system in thermal power plant is important and huge, providing cooling water for auxiliary equipment to enable auxiliary equipment and subsystem to run normally. There is excess of air in the closed cooling water system of some units, which resulted in abnormal operation of closed cooling water pump of the system. Therefore, causes for the failure are detected in detail. The cracked cooling water copper tube of the cooler behind air compressor for ash delivery is detected and air admission is stopped.
