Performance Analysis of Externally Pressurized Gas Journal Bearing Lubricated with Vapor of R134a in Centrifugal Compressor

نویسندگان

چکیده

The performance of an externally pressurized gas journal bearing lubricated with R134a vapor used in oil-free refrigeration centrifugal compressor is calculated by solving Reynold equations the finite difference method (CFD). load capacity, stiffness and mass flow rate refrigerant under conditions various operational parameters are obtained compared that air bearings. In addition, influences average clearance, eccentricity ratios supply pressure on static characteristics bearings investigated discussed detail. It concluded optimal operation different These factors should be considered design process

Lateral Dynamics and Stability Analysis of a Gas Compressor Supported by Hybrid and Active Lubricated Multirecess Journal Bearing

Fluid film forces are generated in multirecess journal bearings by two types of lubrication mechanism: the hydrostatic lubrication in the bearing recesses and hydrodynamic lubrication in the bearing lands, when operating in rotation. The combination of both lubrication mechanism leads to hybrid journal bearings (HJB). When part of hydrostatic pressure is also dynamically modified by means of hy...

Analysis of the Journal Bearing Performance in a CO2 Reciprocating Compressor

CFCs, HCFCs are stipulated to phase out, and other alternative refrigerants like R134a, are also constrained as a result from their high GWP values. CO2 as a natural working fluid now is used in reciprocating compressors due to its uniquely beneficial properties (ozone depletion potential, ODP=0; global warming potential, GWP =1). However, one remarkable characteristics of the CO2 reciprocating...
