Based on the provided context, here's how polymer melt pumps work:
Working Principle
Polymer melt pumps are positive displacement devices where the flow rate is strictly proportional to the pump's rotational speed.
Operation Process
The pump works through a gear meshing mechanism that creates volume changes to transport the melt:
Intake Phase: When the gears rotate in the specified direction, the polymer melt enters the feed zone and fills the tooth spaces between the two gears
Transport Phase: As the gears continue rotating, the melt is carried along both sides into the conveying zone within the gear tooth spaces
Discharge Phase: The gears mesh again, forcing the melt out of the tooth spaces into the discharge zone, where it's pushed through the outlet pipeline
Primary Functions
Pressurization: Increases pressure of high-temperature, high-viscosity polymer melts from extruders
Stabilization: Maintains stable pressure and flow rate
Metering: Provides precise flow control as the melt is delivered to the extruder head
This system is particularly effective because the positive displacement design ensures consistent, predictable flow rates that directly correspond to the pump's rotation speed, making it ideal for precision applications in plastic, resin, rubber, and chemical fiber production.
