Abstract

PURPOSE: To stably maintain a sealing function throughout a long period, by using two O-rings between a rotary ring and rotary shaft and equally setting balance ratios for sealing liquid and sealed fluid.
CONSTITUTION: A mechanical seal 1 partitions a sealed fluid (d) filled in a casing (c) and sealing liquid (e) by mutually slide contacting a sealing surface 2a of a fixed ring 2, fixedly provided in a shaft hole part (h) of the casing (c), to a sealing surface 4a of a rotary ring 4 fitted to a rotary shaft 3 extended through the shaft hole part (h). Here the rotary ring 4 is provided with a circumferential groove 5 having a stepped part 5a in its internal periphery with a large contour in a side of the sealing liquid (e), while in the periphery of the rotary shaft 3 a stepped part 3c, with a large contour in a side of the sealing liquid (e) by combination of different diameter sleeves 3a, 3b, is provided in a location corresponding to the above described groove 5. Then O-rings 6,8 are mounted to said circumferential groove 5 and separated by spacers 7, 9.
