spinning metering pump
The spinning metering pump is a core piece of equipment in chemical fiber production. Its function is to accurately meter and uniformly
deliver polymer melt or solution to the spinneret, ensuring uniform linear density and stable quality of the finished fiber. The following
section introduces it from six aspects: working principle, types, structure, performance requirements, application scenarios, and key
selection points:
I. Working Principle The spinning metering pump achieves quantitative fluid control through gear meshing. When the gears rotate,
the volume of the meshing chamber changes, creating a negative pressure zone and a high pressure zone:
Negative pressure zone: Melt or solution is drawn in at one end of the inlet, filling the tooth grooves;
