What are the benefits of plastic extrusion pumps

The outlet pressure of the extruder is greatly affected by various factors, which will affect the size accuracy of the product. If we add a melt pump between the extruder's exit and the die head, it can effectively stabilize the pressure fluctuation of the extruder outlet and make the linear extrusion become possible, thus improving the size of the plastic products. Increase the extruder output per unit time. Now let's learn about the advantages of plastic extrusion pumps.

The benefits of plastic extrusion pump:

1. It has the characteristics of linear extrusion, facilitating the coordination of upstream and downstream equipment. Because the leakage flow of the gear pump is less, the transport capacity of the pump is basically linear with the speed of the pump. After the gear pump speed changes, the flow rate can be exactly known, because it can determine the speed of the synchronization of the upper and lower equipment and the gear pump, and use the information of pressure and temperature collected at the inlet of the gear pump, the outlet, and so on. The whole process of extrusion is monitored and feedback on-line.

2, increase production, reduce energy consumption, achieve low temperature extrusion, extend the life of the machine. As the polymer melt pump is installed in the extruder, the pressure reducing function of the extruder is transferred to the gear pump. The extruder can work at low pressure and low temperature, and the leakage flow is greatly reduced and the output is increased.

3, it can achieve stable extrusion, improve the dimensional accuracy of extruded products, and reduce the reject rate. In the extrusion process, it is difficult to avoid the phenomenon of uneven feeding quantity, fluctuation of the temperature of the barrel and head, and the pulsation of screw speed.
