摘要： An improved drive shaft seal including a first sealing ring to be mounted within a housing, a second sealing ring to be mounted within the housing in contact with the first sealing ring in such a manner that one ring rotates relative to the other, and a thermally conductive cup having an end portion to be mounted in contact with one of the rings within the housing and a wall portion extending outside the housing. Heat is dissipated from the rings through the cup to the atmosphere surrounding the housing. In a preferred embodiment, the wall portion of the cup is perforated and ring-shaped so as to have large surface area and a large surface area-to-volume ratio. In another preferred embodiment, a fan is mounted outside the housing so as to blow air past the wall portion of the cup. The invention may be embodied in a pump, in which the first sealing ring is attached to the pump drive shaft so as to rotate with the drive shaft. The second sealing ring is mounted so as to remain stationary with respect to the housing.
