Abstract

The aim of this study is the using laboratory tests to evaluate the anti-wear performance, reduce friction and improve the heat transfer of powerful industrial oil in gearbox of rotary machines called Shell Omalla S2 G220 containing nano additives to the base oil. For this purpose, silica and alumina nano particles were selected to be added to the mentioned oil. In this study, concentrations of nano particles was 0. 1, 0. 2 and 0. 4 wt% to prevent nanoparticle deposition problems on gear components. Surfactant Span 80 and an ultrasonic probe were used to disperse nanoparticles inside the base fluid and to achieve a stable nano-fluid. Then, the physical properties of the base oil and the nano lubricants including viscosity, viscosity index, density, pour point and ignition point were measured. The standard four ball Wear test, friction coefficient and conduction Heat transfer coefficient test were performed on the samples. After the experiments, the best combination of oil containing nanoparticles was selected in comparison with the base oil and charged to pump gearbox for the Elemental analysis test. The results of this study showed 7. 4% reduction in wear, 10% reduction in friction coefficient and 10. 7% improvement in the conduction Heat transfer coefficient. The results of the Elemental analysis also showed abrasive elements of the internal components of the gearbox reduced significantly.
