Title:
並列ポンプ装置を備えるフライホイールシステム
Document Type and Number:
Japanese Patent JP4689139
Kind Code:
B2
Abstract:
A flywheel energy storage system, including a plurality of pumps arranged in parallel for simultaneously drawing-off and absorbing substantially all of the gases that evolve from a flywheel assembly during high-speed operation, is disclosed. The plurality of pumps includes at least one pump for pumping mainly water vapor; and, at least one pump for pumping mainly active gases. The at least one pump for pumping mainly water vapor plurality of pumps is disposed in a gas storage chamber that is separate from the main housing of the flywheel system. The at least one pump for pumping mainly active gases is disposed in a container external to the main housing and fluidly coupled to the gas storage chamber. A drag pump assists the plurality of pumps in the gas storage chamber by pumping the evolved gases from the main housing to the gas storage chamber.
