Abstract

In extrusion technologies based on thermal effects, one of the most important constructive-technological parameters of the process is the filing of a vacuum pump included in the machine. When this occurs, related to the process of «effervescence» of the extrudate and cooling with simultaneous condensation of the water vapor influence on the choice of the vacuum pump. On the basis of a balance of air flow in the pneumatic system of the upgraded extruder in the paper an attempt of a theoretical substantiation of the rational working of air pressure in the vacuum chamber of the upgraded extruder with a vacuum effect.
