摘要：PURPOSE:To cut cost by revolving a vane wheel, pouring water into a pump casing, and by pumping up water by aspirating the air in a suction pipe outside the pump casing. CONSTITUTION:A vertical shaft pump 1 is started by revolving a vane wheel 14 and at the same time by pouring water into a pump casing 11 through a water feeding pipe 3 by a submersible pump 4. The introduced water inhales a portion of the air in a suction pipe 2 by the revolution-drive of the vane wheel 14 and mixes said air as air bubbles and discharges the mixture outside the pump casing 11. Then, the inside of the suction pipe 2 is decompresd, and water feeding action is generated. Therefore, the need of using the parts such as vacuum pump and water filling detector is avoided, and cost cut can be realized.
