ことを特徴とする立軸ポンプ。 An impeller is disposed above a specific part of the pump that corresponds to the minimum water level below which air will be sucked in if the submerged water level of the suction bell mouth is below this level, and the tip of the suction bell mouth is brought to the minimum water level. Place it in a place where it can be submerged in water as much as necessary.
An intake passage is provided to communicate the suction port of the impeller with the atmosphere, and a valve body is provided to open and close the intake passage. A float member is provided as a node, and an intermediate node is interposed between the float member and the valve body as a follower via an actuation delay mechanism, and the valve body is opened at a water level below a minimum water level. A vertical shaft pump characterized in that the valve is configured to close at a water level equal to or higher than a pumping start water level.
