To provide a fluid system capable of arranging a fluid machine at an optimum submersion depth different between when a water turbine function is exerted and when a pump function is exerted.SOLUTION: A fluid system includes: a support mechanism 20 that supports a fluid machine 30 to be movable in a vertical direction in running water; a float part 36 that is provided on the fluid machine 30 and can generate buoyancy capable of moving the fluid machine 30 upward in the running water; and a compression spring 23 that is provided on the support mechanism 20 and can exert downward urging force according to the buoyancy on the fluid machine 30 and the float part 36. The fluid machine 30 is configured to switch between a water turbine function and a pump function according to a water level of the running water, and is configured so that it can be located at a water turbine submersion depth A when the water turbine function is exerted and it can be located at a pump operation submersion depth, which is deeper than the water turbine submersion depth A, when the pump function is exerted.SELECTED DRAWING: Figure 2
【課題】水車機能を発揮するときと、ポンプ機能を発揮するときとで、それぞれ異なった最適な没水深さに流体機械を配置することができる流体システムを提供する。【解決手段】流体機械３０を流水中において垂直方向に移動可能に支持する支持機構２０と、流体機械３０に設けられ、流体機械３０を流水中において上方に移動させ得る浮力を生じさせることができるフロート部３６と、支持機構２０に設けられ、流体機械３０及びフロート部３６に対して、浮力に応じた下向きの付勢力を作用させることができる圧縮バネ２３と、が備えられ、流体機械３０は、流水の水位に応じて、水車機能とポンプ機能とが切り替えられるように構成されるとともに、水車機能を発揮するときは水車運転没水深さＡに位置させ、ポンプ機能を発揮するときは水車運転没水深さＡより深いポンプ運転没水深さに位置させることができるように構成されている。【選択図】図２
