Optimization Of Screw Compressor Design
نویسندگان
چکیده
An optimisation procedure for twin screw compressor design is described, which is based on an analytical algorithm for rotor profile generation combined with a differential model of the fluid flow and thermodynamic processes within the machine. Rotor profiles are generated from a rack which have both stronger female rotor lobes and higher displacement. Compressors thus designed have higher delivery rates and better efficiencies than those using more well known profiles. Some optimization issues of the rotor profile and compressor ports are discussed, using a 5/6-106 mm screw compressor to illustrate the results. It is shown that the optimum rotor profile, compressor speed, oil flow rate and inlet temperature may differ significantly when compressing different gases or vapours.

Design Optimization of an Oil-Flooded Refrigeration Single Screw Compressor
A single screw compressor is usually sealed by means of its tiny clearances. The theoretical research and the practice application shown that the leakage in the working process is always the key factor influencing the performance of this kind of compressor. Besides meeting the need of lubrication, the oil injection can greatly improve the sealing effect. It is obvious that the reduction of clea...
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...

In the field of screw compressors, although the basic operation of flow systems is well known and the analytical methods for their performance prediction are well established, only few attempts of investigating the flow by means of CFD can be identified in the available literature. In this paper, two important aspects of numerical investigation of the flow behavior are presented. Firstly, metho...

The profile gradient method has been recently introduced as a means of generating screw compressor rotor profiles. As a single parameter method, this procedure is convenient for the optimisation of screw compressor rotors and evaluating their quality. In this paper, the procedure is modified to adopt the pressure angle instead the profile gradient and applied to a screw compressor rotor rack. O...
