Abstract

PURPOSE: To provide easy means for improving water and air tightness by installing space fillers in the openings between water-tight packing segmensts.
CONSTITUTION: Seal water packings making up a seal water unit 5 for a main shaft 2 are composed of upper and lower seal water packings 8A and 8B of uniform configuration, with each of the upper segment packing connections located nearly in the middle of each of lower segment packing connections. Between segment packings, V-shaped space fillers 10 are inserted and secured to the packing case by means of anti-skid pins 9. This allows the space fillers 10 to diminish gaps between segments packings and prevents rotation, thereby improving the air and water tightness of the seal water unit 5 and dispensing with a need for indenting packing segments which contributes to simplifying the work process
