Oil&Gas - Centrifugal compressor - PetroWiki

1/6/2015· In a centrifugal compressor, energy is transferred from a set of rotating impeller blades to the gas. The designation “centrifugal” implies that the gas flow is radial, and the energy transfer is caused from a change in the centrifugal forces acting on the gas. Centrifugal compressors deliver high flow capacity per unit of installed space

Oil Viscosity Explained - KEW Engineering

What is Viscosity? Viscosity, by definition, is an oil’s resistance to flow and shear. It is the single most critical physical property of the oil as it affects both the wear rate and the fuel efficiency. Water is a low viscosity fluid; syrup is a high viscosity fluid. With o il, like syrup, as you increase the temperature, the viscosity lowers, meaning it flows faster, or more easily.

Sleeve Bearing Lubriion

Every sleeve bearing has some common design characteristics as shown in Figure 2. The components that are separated by the oil film in a plain bearing are the bearing liner and the shaft. The shaft is composed of high-quality, wear-resistant, structurally strong steel. The bearing liner may be made of a single layer or multiple layers
