GB/T 9877-2008 Hydraulic fluid power—Guide specifications for designing rotary shaft lip type seals
Abstract
This standard specifies the basic requirements for the structural design of rotating shaft labyrinth seals, including the design requirements and size series of the assembly support, main lip, secondary lip, skeleton, spring, etc. of rotating shaft labyrinth seals with basic dimensions conforming to GB/T 13871.1. In addition, this standard also provides the main parameters of conventional design and special design parameters (such as the design of lip-mouth reflux form, etc.). This standard applies to rotating shaft end installed in equipment, which plays a sealing role for liquids or lubricating grease. The pressure in the sealing chamber should not exceed 0.05 MPa.
