Abstract

The invention discloses a seal ring pairing device and an application method thereof, and relates to the technical field of mechanical seal ring pairing. The seal ring pairing device specifically comprises a ceramic seal wide ring and a ceramic seal narrow ring. The upper surface of the ceramic seal wide ring is movably connected with the lower surface of the ceramic seal narrow ring. A pluralityof protruding blocks are arranged on the inner wall of the ceramic seal narrow ring and are in a calabash shape. The ceramic seal narrow ring is made of graphene and other materials with low hardnessand the lubricating function. The ceramic seal wide ring is made of high-hardness B4C materials. Through the arrangement of the ceramic seal narrow ring and the protruding blocks, stable seal is achieved when the ceramic seal wide ring and the ceramic seal narrow ring relatively rotate, the effect of mechanical seal ring pairing stability is achieved, and the problem about mechanical seal reliability in the severe environment is solved.

Description

technical field [0001] The invention relates to a pairing of mechanical sealing rings, in particular to a pairing device of sealing rings and a method for using the same. Background technique [0002] Mechanical dynamic seals have the advantages of high reliability and long life. Product design requirements are getting higher and higher, and strict requirements are put forward for reliability, service life and maintenance-free performance. In addition, some mechanical seal applications have higher cleanliness requirements for the sealing medium. The ring planes are always in contact to achieve a rotary dynamic seal. In order to ensure that the dynamic seal can still seal after wear and tear, the mechanical seal requires that there is a certain hardness difference between the two sealing rings that fit together. The narrow ring is generally made of graphite and other materials with slightly softer hardness and self-lubricating properties, so as to ensure that there is a cert...
