The oil pressure test of the hydraulic impeller blade

[摘要] This article introduced the structure of the Kaplan runner in hydropower station and the operating process of the oil pressure test has been described. What's more, the whole process, including filling oil to the runner hub, the movement of the runner blade, the oil circuit, have been presented in detail.Since the manipulation of the oil circuit which controlled by three Valve groups consisting of six valves was complicated, the author is planning to replace them with 3-position 3-way electromagnetic valves, so we can simplify the operation procedure.The author hopes this article can provide technical reference for the oil pressure test.
