Abstract

PURPOSE: To make injection water reach effectively the sliding surface of a mechanical seal and at the same time make the gas in a stuffing box exhausted in a short time, by making a small hole on the side wall of a guide vane.
CONSTITUTION: A guide vane 7 has a cylinder 7a and a small hole 7b on the side wall 26 and also has an annular projection. A cover 4 forms a cylinder 4a incorporating the guide vane cylinder 7a with an appropriate clearance, and also has an appropriate clearance between the upper end of the side wall 26 and the end of the cylinder 4a to form an inflow port 24 toward the small hole 7b. A stuffing box 23 is communicated with a discharge port of in an impeller 3. The circulation water discharged from the small hole 7b is injected toward above the level of the sliding surface of a mechanical seal 15 and fed to the shaft seal, and at the same time the gas in the stuffing box 23 is exhausted in a shorter time
