A pump system with wave powered impulse turbine

Japan is surrounded on all sides by the sea. Thus, ocean development has been carried out in the midst of environmental protection. In this consequence, a numerous researches have been conducted on various apparatus that can utilize the wave energy. In this study, a pump system based on the wave energy was developed for pumping the seawater, the facility uses (e.g. aquarium, swimming pool with seawater, etc...), the preservation of farming conditions of marine products, and the replacement of seawater by pumping of the deep water. A radial pump that can be operated by an impulse turbine used for wave energy conversion was developed. The performance of this pump system was investigated experimentally. From the experimental results, the pump system could be started approximately in 20 seconds.
