Improving extruder performance with the use of melt pumps
Melt pump is a supporting equipment in the plastic extrusion industry, mainly used in conjunction with extruders to improve their performance. The two main functions of an extruder are heating, melting, and pressure conveying, which are closely combined. Due to the inherent instability of the melting process, the pressure conveying process also exhibits instability, causing the output of the extruder to be in a state of shock and fluctuation. The main purpose of using a melt pump attached to an extruder is to eliminate these impacts and fluctuations.

1. Pressure conveying mechanism
It is meaningful to compare the pressure conveying mechanism between the extruder and the melt pump. In summary, the melt pump is an active conveying mechanism that can press polymer melt at a highly stable rate. The extruder generates pressure through viscous resistance.

2. Process control
When a melt pump is connected to an extruder, a control system is required to maintain an appropriate balance between the pump speed and screw speed of the melt pump. The simple control measure is to adjust the screw speed so that the inlet pressure of the melt pump remains constant. A more complex measure is to adjust the motor of the extruder and the motor of the pump to achieve a constant extrusion amount, even if the flow resistance increases due to slow and gradual blockage of the filter.

The melt gear pump is applied to the reaction and transportation of high-temperature and high viscosity polymer melts in large-scale polymer production devices, such as the bottom discharge, pipeline transportation, and pressurization of high-temperature and high viscosity polymer melts in industries such as resin and chemical fiber; It can also be applied to the extrusion molding of plastic, resin, rubber products, such as granulation, film, pipe, plate, sheet, and other industries, installed between the extruder outlet and the mold head, playing a role in boosting, stabilizing, and measuring; It is also applied in various chemical processes, with a wide viscosity range of the conveying medium, suitable for pure and viscous fluids.
