本文介绍了抽水蓄能机组的功能和优点。水泵水轮机转轮是抽水蓄能机组的核心部件之一,为保证转轮的焊接质量和制造尺寸,结合转轮自身结构特点,我们制定了合理的转轮装焊工艺,并阐述了如何采用该工艺保证抽水蓄能机组高质量的焊接要求。 This article describes the features and benefits of a pumped storage unit. Pump turbine runner is one of the core components of pumped storage unit. In order to ensure the welding quality and manufacturing size of the runner, we have developed a reasonable process of assembling the rotor with the structural features of the runner itself and described how to adopt the Process guarantees pumped storage units of high quality welding requirements.
