Control of wear applied to compressors: trends in lubricant analysis

The normal function of equipment produces a big quantity of particles of different sizes, as a result of the different kinds of wear. To control the quantity of wear the most important parameter in analysis of lubricant is the concentration of wear particles. The trends in lubricant analysis are used to optimised the maintenance in compressors. In this way, we can decrease the maintenance cost, save money, and to obtain a better description of the state of machines. In the laboratory, the trends in wear of screw compressors are compared with the normal behaviour of compressors in the industrial plant. This comparison can be used to obtain the dysfunction in the running. In the present research we describe those parts of the compressor which are contributing to the total wear. Moreover, we have developed applied simulation considering the special environmental conditions of the zone. Related model let us know the relation between the failure and the environment. Also, we can know the indirect failures (second failure modes) that proceeds from primary failure wear. (C) 1999 Elsevier Science S.A. All rights reserved.
