About Lewis Acids as Activators of the Processes of Corrosive-Mechanical Wear of Gear Metering Pumps

Resumo

The effect of the metal halide FeCl₂ and its hydrate on increasing the intensity of corrosion-mechanical wear of the parts of gear metering pumps during the dosing of spinning solutions for spinning aramid fibers was studied. One of the ways to reduce the intensity of wear and, correspondingly, increase the life of metering pumps by manufacturing pumps of a new design with a casing made of a composite material with a polymer matrix is considered.
