Screw Machines with Longitudinal Circulating Liquid. Communication 1. Pressure-Flow Rate Characteristics

  • Published:
Fibre Chemistry Aims and scope

Abstract

The possibility of organizing longitudinal circulation of polymeric fluids along the channels of screw machines is demonstrated; it levels out the concentrations of additives, required because of the imprecise operation of metering systems in time, and averaging of the temperature of the fluid along the length of the screw. The pressure-flow rate characteristics of screw machines with longitudinal fluid circulation are investigated and the operating conditions in the presence and absence of longitudinal circulation are determined. The region of geometric screw dimensions where longitudinal circulation of polymeric fluid cannot be organized is determined.
