Title:
IMPELLER FOR FUEL PUMP
Document Type and Number:
WIPO Patent Application WO/2017/073587
Kind Code:
A1
Abstract:
This impeller for a fuel pump comprises a phenolic resin and an inorganic filler. When a free induction decay curve obtained by solid echo through a pulse NMR measurement at 90°C is approximated by the sum of the relaxation curves of three components, the amount of a component having the smallest spin-spin relaxation time is 70% or more of the overall amount. The amount of the component having the smallest spin-spin relaxation time corresponds to the amount of a component in which the phenolic resin included in the impeller for a fuel pump is crosslinked. As the crosslink density of the phenolic resin increases, the swelling rate with respect to a liquid containing fuel and water decreases. The impeller for a fuel pump according to the present disclosure has a lower swelling rate with respect to fuel and water than that of an impeller molded from a PPS resin.
