“How would you perform an oil flush for a rotary-screw air compressor?”
The purpose of oil flushing is to clean the system in contact with the lubricant. Whether it involves a machine, storage container, lubricant line, hose or lubricant conditioning system, flushing is designed to eliminate or control contamination that can negatively affect the performance of the lubricant or machine.
“Synthetic” is an all-encompassing term used to describe manmade base fluids utilized in the formulation of lubricants. Synthetics can have sharply different performance attributes and can at times be mutually incompatible. The differences between these base fluids must be understood in order to accommodate the needs of the machine application as well as the properties of the lubricant.
It has been proven that the No. 1 cause of machine failure is the degradation of component surfaces. These surfaces can degrade in a variety of ways, but the most destructive is via particle contamination. While you may already be aware that dirt is harder than most metals found in machines, do you know how much harder it is?
“Would you recommend an offline vacuum pump/filtration unit for a hygroscopic oil if water content is on the high side?”
“I read in a recent article that the higher the operating temperature, the lower the oil’s saturation point. I thought the correlation was that the saturation point increases as the oil’s operating temperature increases. In other words, the warmer the oil, the more dissolved water it can retain. Is this correct?”
