Abstract: A mechanical seal control apparatus includes a thermally responsive element for reducing or negating face contact pressure upon at least one seal face of a mechanical seal when heat is generated within the mechanical seal above a pre-determined temperature. The thermally responsive element preferably includes, or is, a shape-memory material sensitive to thermal changes to increase or decrease in size, or change in shape, when subjected to changes of temperature of the mechanical seal and is, preferably, a bimetal, such as, for example, nitinol. Upon cooling of the mechanical seal, the shape-memory material substantially, or entirety, reverts to its original size or original shape to increase the face contact pressure for retaining the integrity of the mechanical seal.

Abstract: A mechanical seal 30 is disclosed comprising a sleeve 32 which is adapted to be affixed to the shaft 34 of a item of mechanical equipment, together with a rotary component 42 which carries a rotary seal face 44. Two O-ring grooves 46, 48 are provided on the sleeve 32, the first 46 being remote from the rotary seal face 44 and cut somewhat deeper into the sleeve 32 than the second 48. The rotary component 42 has a first region 50 remote from the rotary seal face 44, the inner surface of which has a relatively small diameter and a second region 52 between the first region 50 and the rotary seal face 44, the inner surface of which has a larger diameter. A pair of O-rings 54, 56 are located in the O-ring grooves 46, 48 and seal against the inner surface of the rotary component 42. The net thrust, if any, acting on the rotary component 42 and hence on the rotary seal face 44 tends to close the seal face irrespective of whether the barrier fluid pressure is in excess for less than the product pressure.

Abstract: A mechanical seal assembly has rotational and stationary sealing members) and a drive unit, which is axially adjacent one of the sealing members. An energizing member urges the drive unit towards the sealing members. A retainer axially and radially retains one of the sealing members. The drive unit is in contact with one of the rotational and stationary members by way of contacting surfaces which are in the range of 1 and 20 light bands of flatness, inclusive.

Abstract: A flow inducing ring for a mechanical seal includes a body portion having a first edge face and a second edge face, and at least one first groove extending both axially and circumferentially in one direction across the body portion from the first edge face to the second edge face. At least one second groove extends both axially and circumferentially in an opposite direction across the body portion from the first edge face to the second edge face. Each of the first groove and the second groove includes an entry portion, configured to draw a barrier fluid into the groove from the first edge face, and an exit portion, that is configured to expel barrier fluid from the groove to the second edge face and to impede the drawing of barrier fluid into the groove from the second edge face. The first and second grooves preferably have substantially constant cross-sections throughout the entirety of their lengths for enhanced uniform fluid flow.
