Apparatus for Delivering Sealant at a Predetermined Pressure to a Stuffing Box of a Shaft |
摘要 |
A delivery unit (40) for automatically delivering a viscous sealant at a predetermined pressure to a stuffing box (70)of a shaft (20) is disclosed. The delivery unit (40), such as a pressure booster incrementally displaceable piston, is controlled to deliver the sealant at a predetermined pressure on demand when the pressure of the sealant within said stuffing box is less than the predetermined delivery pressure being sufficient to promote adhesion of the sealant onto a shaft segment and to thereby prevent or retard the egress of working fluid from a corresponding working chamber (17) of a machine adapte to perform work by the shaft. A system for reducing the pressure of sealant within a stuffing box by use of the delivery unit and of an impeller-based dynamic seal is also disclosed.
