随着汽轮机事业的发展,特别是采用压水堆的核动力装置,汽轮机蒸汽工质的参数一般较低,这就使汽轮机未级或末几级受到温蒸汽水滴的冲蚀,这不但影响机组效率,而且会影响到叶片的寿命和安全可靠的工作。因此研究湿蒸汽双相流动以提高汽轮机效率和防水蚀,越来越引起人们的重视。为了测定湿蒸汽的湿度就迫切需要研制测湿仪。 With the development of the steam turbine industry, especially the nuclear power plants using pressurized water reactors, the parameters of the steam turbine working fluid are generally low, which causes the steam turbine to be eroded by warm steam droplets in the last stage or the last stage, which not only affects the unit Efficiency, but also affect the blade’s life and safe and reliable work. Therefore, research on wet steam two-phase flow to improve turbine efficiency and water erosion, more and more aroused people’s attention. In order to determine the humidity of wet steam on the urgent need to develop moisture meter.
