二十万千瓦汽轮机的调节系统,从试制到定型,其中经历了完善化工作和国家鉴定工作,这些工作都是建立在机组运行实践的基础上的。由于广泛地吸取了用户的实践经验,使二十万机的调节系统逐步趋于完善,成为至今的定型产品。完善化工作主要以首台二十万机的调试和运行经验为依据,出发点立足在提高调节系统的安全可靠性。重点内容包括防火安全性,系统工作可靠性和调整方便。以下叙述存在问题和改进的情况。
The adjustment system of 200,000-kilowatt steam turbine, from prototype to setting, has undergone perfection work and national appraisal. All these work are based on the operation of the unit. As a result of extensively absorbing the user’s practical experience, so that 200,000 machines gradually adjust the regulatory system tends to become the stereotypes products so far. The improvement work is mainly based on the commissioning and operation experience of the first 200,000 aircraft. The starting point is based on improving the safety and reliability of the regulating system. Highlights include fire safety, system reliability and easy adjustment. The following describes the problems and improvements.
