Table 5—5 Compressor Lubrication Schedule
Compressor Lubricating Oil
Cooper Turbocompressor cannot specify a fixed interval between lubrication system oil changes because
of the wide variety of operating conditions that exist. Therefore, the operator should inspect the oil
visually daily to monitor changes and/or possible deterioration. Compare the appearance of oil from the
reservoir with new oil, and watch for changes in the appearance of the oil as follows:
· If the oil appears darker than normal, that is an indication that there is probably some
contamination.
· If the oil appears muddy or contains any white emulsion, that is an indication that there is
some contamination with water.
As the situation requires, have the oil tested for viscosity, acid, water and other contamination. A
reputable commercial laboratory can easily detect the presence of any such contamination,
Whenever the performance of the lubricating oil is suspect, Cooper Turbocompressor recommends
additional testing for the presence of enhancing additives in accordance with The American Society for
Testing and Material (ASTM) as defined in Table 2—1, Oil Specification.
