Computed Universal Dependence for Determining Leakage of Media Through Groove Seals

  • V. A. Melnik

The calculation of leakages of liquid and gaseous media through straight-through and non-straight-through groove seals is currently performed using dependences that differ in terms of the composition and form of the representation of the input parameters. In the present article questions related to the use of a generalized universal dependence for calculations of leakages of compressible and incompressible media in the channels of groove and labyrinth seals of shafts that are widely used in pumps, turbines, and compressors are considered. An analysis of the well-known dependences is carried out, a technique for processing the results of studies of leakages for groove seals that differ in terms of the shape of the channels of the seals, and the use of these results in a standardized universal dependence for calculation of leakages is proposed.
