Explanation of the Features of Meltblown Machine Metering Gear Pumps

The gear and shaft of the meltblown metering gear pump are integrated, utilizing a through-hardening process to achieve a longer service life. The "D"-type bearing incorporates a forced lubrication mechanism, allowing polymers to pass over the bearing surface and return to the pump's inlet side, ensuring effective lubrication of the rotating shaft. This feature reduces the likelihood of polymer retention and degradation. The precisely machined pump body enables precise fitting between the "D"-type bearing and the gear shaft, ensuring that the gear shaft remains concentric and preventing gear wear.

The spiral seal structure of the meltblown machine metering pump, combined with a PTFE lip seal, forms a water-cooled seal. This seal does not actually contact the surface of the shaft; instead, its sealing principle relies on cooling the polymer to a semi-molten state to create a self-sealing effect. Reverse spiral grooves are machined on the inner surface of the shaft seal to push the polymer back towards the inlet. For ease of installation, the manufacturer has designed a circular bolt mounting surface to match the flange installation of other equipment, facilitating the manufacturing of cylindrical flanges. The meltblown metering gear pump is equipped with heating elements matched to the pump's specifications, available as an optional feature, ensuring rapid heating and heat control.
