Abstract: One pumping station for multi-machine was planned for the hydraulic system of intake gate hoist at Shuikou hydropower station, which caused the problems such as sharing of pipe, pressure oil filter and valve group for oil source control. Inspection, repairing and replacement couldn't be carried out during operation of the power generator. Also, as the pressure in chamber couldn't release, the pressure rose due to the environment temperature. Aiming at the problems, renovation was implemented. This paper introduced the renovation design and the operation afterwards, for reference.

Key words: intake, rapid-drop gate, hydraulic system, renovation design
