In the production line of Haike High Temperature PID Control System Melt Pump Plastic Extruder, the plastic feeding amount is not balanced in general, and the density of raw materials sometimes changes. In addition, due to the internal screw movement mechanism of the extruder, the general machine The pressure of the melt of the head is usually expressed as a pulsed fluctuation, generally up to 0.5 MPa to 3 MPa. If a melt gear pump is installed at the rear of the machine head, the meshing degree of the teeth can be increased by continuous meshing between the teeth and the involute type helical gear technology used, thereby continuously and smoothly pressing the material to eliminate the pressure. fluctuation. When the melt pump is not installed in the production line, the pressure of the melt on the machine head fluctuates greatly; the outlet pressure after the melt pump is installed has almost no fluctuation.
