ABSTRACT:
A mechanical seal assembly provided with an annular seal cavity which encircles the seal parts. A coolant circulation tube (i.e., an exit tube) projects through the housing into the seal cavity and is provided with a window-shaped opening in the sidewall thereof opposing the direction of coolant circulation. The lower end of the tube is preferably closed off by a bottom wall which is inclined outwardly away from the rotating seal parts in the direction of fluid circulation. This bottom wall has a lower edge defining the lower edge of the window and disposed closely adjacent the periphery of the rotating seal parts. The substantial quantity of circulating coolant, and the substantial velocity head thereof, passes through the window into the inner end of the tube so that the velocity head is converted into a significant static pressure head, whereupon the liquid is pumped radially outwardly of the tube through a closed circuit having a heat exchanger associated therewith. This circuit at its other end connects to an inlet hole which communicates with the seal cavity at a location which is circumferentially spaced from the tube.
