Abstract

PURPOSE: To increase sealing effects by forming a very small gap between the sealing portion and the peripheral surface of an rotary axis; and by forming a sealed water pot with a large diameter on the opening end side.
CONSTITUTION: The pressurized water in a pump chamber 2 flows into the gap of the axis sealing portion 6 from the end of a perforated passageway 5 for the axis and a distributing tube 16 for sealing water, then stays in a sealing water pot 7 after passing through the gap, and further leaks out while widening a space between the seal end surface 8 and a sealing ring 11. In this case, the amount of leakage of the pressurized water is exitremely small because the gap δ left in the axis sealing portion 6 is also very small. At the same time, no mechanical friction occurs in the axis sealing portion because of the leakage. In addition, when there is no pressurized water in the sealed water pot 7, the sealing 11 is attached with pressure to the seal end surface 8 by the force of deviation, so the open air can be prevented from entering the pump chamber 2 at the time of starting the pump.
