Installation of the new pendulor for the 2nd stage sea test
1999
The New Pendulor test was proved to perform excellent survivability during 32 months sea test (1 st stage), but conversion efficiency was not high. The main cause was internal oil leakage of a vane pump developed for the Pendulor. In order to improve the efficiency, the Pendulor was studied again especially concerned with the vane pump, using the full-scale pump tested at sea besides using a model pump prepared for seal experiments. Applying the results obtained from the sea test (1 st stage) and the model experiment, the New Pendulor was re-designed and manufactured again. The Pendulor was installed in Aug. '98 at the same site where the former one was tested. In Oct. 98, the 2 nd stage sea test started. It was observed till end of Dec. '98 that the plant efficiency (motor output/incident wave power) was 40∼60% around the rating power (output=5kW) condition. The pump efficiency was 60∼80% that was 22∼42% higher than the 1 st stage.
