A Study of the Thermal Characteristics of the Leading Edge Groove and Conventional Tilting Pad Journal Bearings
Kingsbury, Inc., Philadelphia, PA 19154 In this paper dealing with the tilting pad journal bearing, experim'ental results are presented which show that, at higher shaft speeds, the leading-edge-groove (LEG) design has significantly lower operating temperatures to those of the conventional design of tilting pad journal bearing. Subsequent theoretical analysis has shown that this reduction in pad...
متن کاملProposal Performance Measurement of ATSP Coating and Bulk PEEK Faced Tilting - Pad Thrust Bearings
Background: Under severe operating conditions, such as lubricant contamination, elevated temperatures and high unit loads, the hydrodynamic (HD) lubrication condition in a HD bearing may degrade and be reduced to mixed and boundary lubrication conditions, which traditional pad bearing materials (Babbitt metal) are not able to sustain. For example, Electrical Submersible Pump (ESP) systems are r...
متن کاملCHARACTERIZATION OF HIGH-SILICA MORDENITE OBTAINED BY DIRECT SYNTHESIS
Three high-silica mordenite zeolites differing in SiO440, ratio were prepared by direct synthesis without using any template. The products Si02/A120, ratio is influenced by the starting gel composition. This ratio is increased upon ion-exchange with NH,Cl and subsequent calcination to prepare protonic mordenite. The protonic mordenites with Si02/A1203ra tios of 14.6,29.2 and 34.6 were chara...
متن کاملOn the Characteristics of Misaligned Journal Bearings
Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...
متن کاملA novel term weighting scheme based on discrimination power obtained from past retrieval results
Term weighting for document ranking and retrieval has been an important research topic in information retrieval for decades. We propose a novel term weighting method based on a hypothesis that a term’s role in accumulated retrieval sessions in the past affects its general importance regardless. It utilizes availability of past retrieval results consisting of the queries that contain a particula...
