Principles and Design of Mechanical Face Seals Free PDF Download. Alan O. Lebeck examines the fundamentals and follow of each the design and operation of face seals, ranging from washing machines to rocket engine turbopumps.
Topics embrace materials, tribology, heat transfer and strong mechanics. A wide range of easy and complex models are proposed and evaluated and particular problems equivalent to heat checking, blistering and instability are considered. This book provides 64 tables and 364 references plus helpful suggestions concerning the way forward for seal design.
This book offers important assessment of world literature on radial face-seals is presented with a view to further understanding of seal operation and to acquire some elements of a design method for optimization of their performance. The principal areas examined are hydrostatic, hydrodynamic and boundary lubrication of the faces, and specifically cavitation and the affect of different constructive parameters on the dynamic conduct of these seals.
Writer additionally describes the vital function of sure constructive or practical parameters such as the balancing of the floating element, the form of the interface, the thermal, mechanical and wear distortions of the faces, the damping and stiffness of the spring and of secondary seal the seal geometry.
The functioning of radial face seals includes a number of complex interacting phenomena and is governed by very many parameters. It appears obligatory that experimental analysis be developed to allow us to measure extra accurately the real functioning of these seals. Also, the establishment of a satisfactory method of design calculation of mechanical face-seals requires the usage of computer applications to carefully mannequin seal operation.
