Title:
MECHANICAL FACE SEAL
Document Type and Number:
WIPO Patent Application WO/2015/187657
Kind Code:
A3
Abstract:
A mechanical face seal and a method of using the mechanical face seal are described. The mechanical face seal includes a plurality of groove sets that are etched into a stationary seal and/or a rotating seal ring. Each of the plurality of groove sets includes feed grooves, collection grooves, distribution grooves, a collector, retention cavities and discharge grooves. The mechanical face seal can be used to reduce the friction that is generated from the stationary seal and the rotating seal ring during operation. Additionally, the groove sets work cooperatively to introduce, circulate and expel lubricant between the seal interface, thereby promoting cooling of the seal.
