Benefits of plastic extrusion pumps

The outlet pressure of extruder fluctuates greatly under the influence of various factors, which will affect the dimensional accuracy of products. If we install a melt pump between the outlet of extruder and die, the fluctuation of the outlet pressure of extruder can be effectively stabilized, making linear extrusion possible, and thus improving the dimensional precision of plastic products. Increase the extruder output per unit time. Now let's learn about the advantages of plastic extrusion pumps.

Benefits of plastic extrusion pumps:

1. It has the characteristics of linear extrusion, facilitating the coordination of upstream and downstream equipment. Because the leakage flow of gear pump is less, the transmission capacity of the pump is basically linear with the rotational speed. When the rotational speed of gear pump is changed, its flow can be exactly known. Because the synchronous working speed of upstream and downstream equipment and gear pump can be determined, the pressure and temperature information collected at the inlet and outlet of gear pump can be used to realize the whole process. 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. Because the polymer melt pump is installed in the extruder, the decompression function of the extruder is transferred to the gear pump to complete. The extruder can work at low pressure and low temperature. 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, the phenomena of uneven material feeding, temperature fluctuation of barrel and nose, and fluctuation of screw speed are unavoidable.
