Governments and institutions have the following sustainable development goals: improvement of energy efficiency reduction CO2 emissions, in a “green economy” approach, currently become fundamental drivers that push research activity toward optimization rotating machine components industrial sector, with special focus on lubrication systems too. The is directed towards tribological testing metho...

The rupture analysis of lubricating oil pipe has been conducted through chemical composition analysis, metallographic and fracture analysis. results show that there are machining defects bidirectional vibration at the joint pipe, which leads to fatigue fracture.

Tests were run with both R-12 and R-l34a in a water calorimeter. Refrigerant 12 was run with mineral oil as the lubricant. Evaporating and condensing heat transfer coefficients were calculated over a range of temperatures. To evaluate the impact of the lubricant on the heat transfer coefficients, a oil separator was added. Tests were then run with the oil separator over the same temperature ran...

A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...
