The Computer Simulation of Oil-Flooded Single Screw Compressors
نویسنده
چکیده
A computer model for prediction and analysis of an oil-flooded single screw compressor performance is developed. The model includes suction preheat, pressuri ~~.tion of the gas in the control volume during the suction closure process, flowage of gas and oil mixture through discharge port, leakage of gas and oil. It considers the effect of oil-injection rate, clearances and length of leaka~e paths on leakage, the effect of the discharge port area variation and the epecifio oil-injection rate on the discharge coeft'ioient of the discharge port and the oil shear powers. Some calculated results are presented and compared with laboratory test.

The Design of a Family of Screw Compressors for Oil–Flooded Operation
The design of a family of efficient oil-flooded twin screw air compressors was performed at City University London for Elgi Equipments Coimbatore, India. It was carried out using a software package, which included almost every aspect of the rotor profiling and compressor thermodynamic and geometric modelling with the capacity to transmit calculated output directly into a CAD drawing system. Rac...
متن کاملOptimisation of Screw Compressors
Increasing demands for more efficient screw compressors require that compressor designs are tailored upon their duty, capacity and manufacturing capability. A suitable procedure for optimisation of the screw compressor shape, size, dimension and operating parameters is described here, which results in the most appropriate design for a given compressor application and fluid. It is based on a rac...
متن کاملDevelopment and Optimization of Screw Engine Rotor Pairs on the Basis of Computer Modeling
The paper presents some recent results in the development of new lobe profiles for the main and gate rotors of a screw compressor, based on the computer modelling of the compression process. The new profile, featured by slenderer gate lobes, as compared with standard asymmetric SRM profiles, yields larger cross-sectional flow areas, enabling higher delivery rates for the same tip speeds. The pr...
متن کاملEconomics of water injected air screw compressor systems
There is a growing need for compressed air free of entrained oil to be used in industry. In many cases it can be supplied by oil flooded screw compressors with multi stage filtration systems, or by oil free screw compressors. However, if water injected screw compressors can be made to operate reliably, they could be more efficient and therefore cheaper to operate. Unfortunately, to date, such m...
