Abstract

During operation, the turbine bulb shaft is subjected to static specific stresses (tension, compression, torsion) and dynamic (fatigue, random vibrations). These stresses are the effect of hydraulic forces and moments developed on the rotor blade, the weight of the rotor (with or without oil) in the console and inevitable vibrations, which creates a rotating mass unevenly distributed over the axis of symmetry of the turbine. Observations made on the turbine bulb shafts of the Iron Gate II CHE have revealed cracks in the connection area of a shaft flange that engages it with the turbine rotor. Examination of these cracks leads to the conclusion that they are specific to the inevitable fatigue demands in exploiting the tree and enhancing the environment in which they work. Therefore, in the paper, a presentation and analysis of the damage of bulb turbine shafts from CHE Porţile de Fier II, after a significant number of hours of operation. [ABSTRACT FROM AUTHOR]

2. Fast performance-analysis of rectangular-rounded hydraulic reciprocating seals: Mathematical model and experimental validation at temperatures between −54 and +135 °C.

Subjects
*RECIPROCATING machinery, *CYLINDER seals, *SOLID mechanics, *HYDRAULIC machinery equipment, *VAN der Waals forces
Abstract

Solid mechanics and rough thermoelastohydrodynamics of hydraulic, rectangular-rounded, reciprocating seals with hydrodynamic, asperity, deformation and van-der-Waals stresses are analytically formulated. Seal swelling or shrinkage by fluid exchange and fluid contact starvation are easily set. Computations require less than 0.05 s of a personal computer's time, allowing for extremely fast parametric studies. Experimental validation follows at −54, +23 and +135 °C, far exceeding other studies at both ends of the scale. Theoretical and experimental results are compared after 1000 stroking cycles. This has not been attempted to this extent before but is important to judge a model's applicability post running-in and in effect of seal abrasive wear, and not just for the first few stroking cycles with a brand new seal.

3. Evaluation of the mechanical properties of the X52 high frequency electric resistance welding pipes.

Abstract

The intensity assessment of the line pipe does not include the strength and the impact toughness, but also include the fatigue performance. In this paper, the tensile strength and the impact toughness of both the pipe body and the weld joint of X52 high frequency electric resistance welding (HF-ERW) pipes were measured. The amounts of fatigue for these specimens with and without surface finishing were investigated with a MTS servo-hydraulic universal testing machine at various maximum cycle stresses. The results showed that both the pipe bodies and the weld joints of the X52 HF-ERW pipes had an excellent balance of strength and impact toughness. The cyclic stress of the weld joints decreased more than the pipe bodies, and the resistance to fatigue was greatly affected by the surface defects. The effects of the surface defects on fatigue properties must be considered for the intensity assessment of line pipes. [ABSTRACT FROM AUTHOR]
