Computer Simulation of the Hydrodynamic Lubrication in A Single Screw Compressor
The hydrodynamic lubrication of the teeth of the gaterotor in a single screw compressor differs from the well-known lubrication of bearings. This difference can be related to the constrained fluid film geometry and the conditions of the lubrication. Under these circumstances the convective fluid inertia will affect the performance of the lubrication. During meshing, variations of the filmgeomet...
متن کاملOpportunities for Innovation with Screw Compressors
Screw compressors are at present a widely used means of compressing air, process gas and refrigerants. Computer simulation programs, verified by experimental data and improved by recent advances in mathematical analysis, form a powerful tool for process analysis within these machines and hence for a comprehensive check of innovative suggestions and design optimisation. One consequence of this i...
متن کاملImportant Parameters for Small, Twin-Screw Refrigeration Compressors
This paper deals with open-shaft twin-screw refrigeration compressors in the 10 175 m3/h (10 100 CFM) range. Applications for such compressors are, for example,external combustion engine heat-pumps and transport refrigeration. The twin-screw compressor concept is discussed from following view-points; operational mode and rotor housing design drive arrangement bearings lubricants cooling volume ...
متن کاملLubrication Analysis of Rotary Compressors for HFC Refrigerants
In this study, a practical numerical analysis has been developed in order to investigate the lubrication characteristics between a rolling piston and a crank of rotary compressors. This analysis is treated as a coupled problem of the momentum equations and the Reynolds equation of oil film. Using this analysis, the lubrication characteristics between the rolling piston and the crank for 2-cylin...
متن کاملBall Beating Lubrication in Refrigetation Compressors
When the re:fiigerant R l34a is mixed with an ester oil and usea m compressor bearing lubrication, no EP action is experienced. The refrigerant contains no chlorine and the lubricant additives can not be chemically active like normal EP additives, not to deposit in and destroy the heat excha..>Jgers. The iubricant film thickness thus needs to be considerably larger for an Rl34a compressor beari...
