ールにより上記自由液面室内の液をインペラーの
吸入側に戻す戻し流路を形成し、この戻し流路の
入口に戻し流量を加減するコントロール弁を設け
たことを特徴とする自由液面式ポンプ。 The liquid in the free liquid level chamber is transferred to the impeller through a groove provided between the partition wall that partitions the premna chamber and the free liquid level chamber and a hydrostatic bearing that supports the drive shaft, and a balance hole bored in the impeller back housing. What is claimed is: 1. A free liquid level pump, characterized in that a return flow path is formed for returning to the suction side of the liquid, and a control valve is provided at the inlet of the return flow path to adjust the flow rate of the return flow.
