Abstract
1,244,142. Rotary shaft seals. CRANE PACKING CO. 4 Feb., 1970 [17 Feb., 1969], No. 5441/70. Heading F2B. A vertically disposed rotary shaft 11 is sealed where it extends through an opening 12 in a pressurized housing 10 by means comprising a rotary mechanical seal 29 and a supply of lubricant for the seal comprising upper and lower reservoirs 50 and 52 located respectively above and below the seal contact faces, the bottoms of the reservoirs being interconnected and the top of the lower reservoir 52 communicating with the interior of the housing 10. The seal 29 is housed with radial clearance in a recess 17 in a casting 13 secured to the housing 10 and comprises a rotatable sealing washer 34 which is slidably mounted on a sleeve 36 secured to the shaft 11 and urged by springs 49 into facial sealing contact with a stationary seating washer 30 sealed to an end plate 19 by an 0-ring 31. An annular space 16 is provided between the shaft and the casting 13 so that the lubricant is pressurized by the fluid in the housing 10. A filler plug 54 is fitted in the plate 19 and the washer 30 forms with the plate 19 and sleeve 36, a chamber 58 in which oil leakage past the contact faces 32, 33 of the seal is collected and drained through a tube 60 to a measuring vessel 61.
