Structure Design of Twin-Spirals Scroll Compressor Based on 3C

3C (CAD/CAM/CAE) method is put forward to optimize the structure of TSSC (twin-spirals scroll compressor) from conceptual design to finished products. The mathematical model and virtual model of TSSC are developed. A novel algorithm GA-HPSO combining with the advantages of GA (genetic algorithm), SA (simulated annealing) and PSO (particle swarm optimization) and NN (neural network) is applied t...

Tonsil fibromatosis.

Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...

Development Of An Industrial High Temperature Heat Pump With Twin Screw Compressor

In industrial applications, 90-150°C hot water needed during production processes is traditionally provided by fuelfired boilers. The use of fuel-fired boiler has a low efficiency of energy usage and potential danger of explosion. Byproduced 30-60°Cwaste water with large amount of energy is rejected to environment directly, which causes a great energy loss and thermal pollution. Seeking for a h...

Twin Screw Compressor Performance and Its Relationship with Rotor Cutter Blade Shape and Manufacturing Cost

By making use of a suite of programs for designing profile geometry, cutter geometry and predicting the thermodynamic performance of a twin screw compressor, this paper investigates techniques of obtaining an optimised rotor cutter blade design. The techniques for using different geometric schemes for setting clearances are explained, and the techniques for optimising main manufacturing paramet...
