为确保水冷器的服役周期,针对大检修开工后水冷器内漏的问题,从设计寿命、使用检修以及定期检验等方面进行了讨论,在设计者根据工况特点合理确定水冷器设计寿命的基础上,使用单位和检验机构还应根据水冷器潜在失效模式有针对性地加强日常管理。建议水冷器的停工检修与定期检验应关注管束的使用寿命,以保证检修后水冷器能运行到下一检修周期。
In order to ensure the service life of water coolers, aiming at the internal leakage of water coolers after the start of large-scale overhaul, the design life, service inspection and periodic inspection are discussed. The designer can reasonably determine the design life of water coolers according to the working conditions On the use of units and inspection agencies should also be based on the potential failure mode of water coolers targeted to strengthen the day-to-day management. It is recommended that shutdown and periodic inspection of water coolers should be concerned about the service life of the pipe bundles to ensure that the water coolers can run to the next overhaul cycle after the overhaul.
