Impingement mixing device with pressure controlled nozzle adjustment.

摘要

A closed loop feedback control for a high pressure impingement mixing system. The high pressure impingement mixing device is equipped with a circulation loop containing both a pressure sensor (27) and a flow volume meter (28). Constant pressure and flow volume is achieved by continuous closed feedback loop monitoring of the pressure and flow volume to effect a change in an adjustable pump (9) setting and servo displaceable nozzle needle (10). The nozzle needle adjustment (13) allows maintaining the appropriate pressure and volume on a continuous basis. It also allows altering component ratios and/or flow volumes during a shot in order to affect a change in material or flow characteristics of a produced part.
