    Methods of the rational choice of a labyrinth seal design for gas pumping units
    (2013) Bellaouar, A.; Kopey, B. V.; Abdelbaki, Noureddine
    This present paper describes a method of improving the labyrinth seal design by the development of three-dimensional parametric computer of its model and an anal-ysis of its work for gas pumping units (GPU) using the finite-element method. The authors have improved design labyrinth seal of the GPU according to the criterion of minimum pressure in the last gap by Gauss-Seidel method of optimization, which will increase GPU operational efficiency by reducing flowing medium at various operating modes of GPU. It is shown that change of geometrical sizes and form of creating more compact part of labyrinth seal with inclination them toward greater pressure for an angle of 80° decrease leakages of gas, that in same time considerably influences on the expense of working environment on the output of labyrinth seal
