Abstract: The research and development ability of the department of hydraulic machinery of IWHR have been improved highly over the past 60 years. Much evolvement has been obtained in different fields such as hydraulic model exploitation, development of research and development platform, test technology and re-lated foundation theory etc. It has been the only well-known scientific research institution which is good at the research of hydraulic machinery application and key technology in water resource and hydro-power field. The development and main achievement are summarized for our institute over the past 60 years in hy-dro-power field from four aspects of test technology, hydraulic machinery equipment technology, and numer-ical simulation technology, intelligent evaluation and diagnosis technology for hydropower units and cavita-tion, cavitation and sediment wear. The history of foundation, healthiness and growing of hydraulic machin-ery field is reviewed. The main achievements of the last decade are introduced. Research emphases and de-velopment direction are also expatiated.
