传统除氧器结构为静定结构.随着除氧器尺寸的增加,双支座已经不能满足强度等其它工程指标的需要.增加冗余支座的数量是一种解决问题的方法.处于安全方面的考虑,首要工作是得到可靠性指标.在实际应用前,通过除氧器可靠性以及可靠性灵敏度的计算结果,可以对除氧器参数进行设计.实际应用通常对可靠性要求比较高,讨论了除氧器结构参数设计方法.结果表明通过参数设计可以得到足够的可靠性. With the deaerator size increasing, the double support can no longer meet the needs of other engineering indicators such as strength, etc. Increasing the number of redundant supports is a solution to the problem. The main task is to get the reliability index.In practical application, deaerator parameters can be designed through the deaerator reliability and reliability sensitivity calculation results.Practical applications usually require high reliability, The design method of structure parameters of deaerator is discussed.The results show that sufficient reliability can be obtained through parameter design.
