METHOD OF MULTISTAGE SEAL MANUFACTURING (VERSIONS) Russian patent published in 2008 - IPC F16J15/16

Abstract RU 2331808 C2

FIELD: process.

SUBSTANCE: method of multistage seal manufacturing includes initial definition of its construction for joint distribution of differential pressure lengthways adjoining surface which rotates relative to seals. Seal is modified for supporting rotational stability relative to surface. Seals are manufactured and tested under pressure for definition of pressurised fluctuations. And then seals are modified again for pressure load sharing if there are fluctuations under pressure. Thus, seals divide real-life load under effects of pressurised fluctuations.

EFFECT: reliability of seal is improving.
