The optimum hoisting program for outlet gate of pumps in large sized axial flow pumping station under super camelback operation, has been researched by adopting hydraulic transient control theory, electrohydraulic control and pressure accumulator techniques. The double speed gate with accumulative and hydraulic control and its hoisting system have been developed. Thus, the double speed wholly automatic hositing of outlet gate of pumps under starting up and stoppage process of pumps, is implemented. And therefore the problem of so called super camelback opeartion of large sized axial flow pumping stations, is solved. It will play an important role in guaranteeing normal safety operation of units and raising economic benefit of pumping stations. [
