ら後端に向けて螺旋状に旋回形成した羽根を有す
るポンプ羽根車において、前記ボス部先端側に位
置する羽根には、ボス部外周面との付け根部分に
、ボス部先端と羽根の負圧面を滑らかに結ぶ平滑
部を形成したことを特徴とするポンプ羽根車。 In a pump impeller having vanes spirally formed on the outer peripheral surface of the conical boss part from the tip of the boss part toward the rear end, the blades located on the front end side of the boss part have blades formed on the outer peripheral surface of the boss part. A pump impeller characterized in that a smooth part is formed at the base of the boss part to smoothly connect the tip of the boss part and the negative pressure surface of the blade.
