1. Experimental study of thermal effects in tilting-pad journal bearings at high operating speeds

Author

Subjects

Abstract

In this work, a test machine, experimental results and the comparison between theoretical TEHD results and experimental data are presented. The tested bearings are located in two speed increasing and reduction gearboxes (back-to-back test bed). The shaft is driven by a 1 MW motor. The bearing diameter and the bearing length are equal to 160 mm. The rotational speed varies from 2700 rpm (22 m/s) to 11,880 rpm (100 m/s). The applied load is up to 88,000 N. Temperatures in the bearing (film/pad interface, oil, pad and housing), power losses and oil flow are measured. The influence of the bearing design and of the pivot position on the pad is analyzed.

Abstract

Lactulose is industrially produced by the homogeneous alkali catalysed isomerisation of lactose. The use of heterogeneous alkaline ion-exchangers as catalyst can result in a simpler overall process and in higher selectivities.The effect of the type of ion-exchanger, particle diameter, temperature and sugar concentration on the kinetics has been studied. A kinetic model is given which can be used to describe the experimental results. Loss of selectivity can occur due to a limiting diffusion rate. High sugar concentrations are beneficial for a high yield.Some proposals are given for process improvements.
