Abstract

PURPOSE: To improve cooling and lubricating performance and improve sealing performance and prolong the life of a sealing apparatus, in the double type mechanical seal used for sealing and circulation of sealing oil.
CONSTITUTION: The sealing oil from a flowing passage 7 is filled in the passage 10 inside a space and a holder 9, space 11, and the communication hole 12 inside a rotational ring 6. When the ring 6 is rotated through the rotation of a shaft 5, the sealing oil inside the hole 12 has different centrifugal forces at right and left because of inclination of the hole 12, and the oil circulates in the direction of arrow A. Owing to the circulation, the frictional heat generated on the sliding surface between the ring 6 and the static sealing rings 4a and 4b is taken away, and also the minute powder formed in wear is removed. As for the rotational ring 6, the degree of cooling due to the circulation oil differs on the sliding surface F in the periphery of the holes 12 and on the sliding surface G, therebetween, so munute undulation is formed on the sliding surface because of the difference of thermal expansion, and the sealing oil is introduced from the surroundings into the wedge-shaped gap thus formed, and a fluid film is formed around the gap, so increase of the load capacity, prevention of seizure on the sliding surface, and prolongation on of life can be caused for the sealing apparatus.
