Definitions

  • the present invention relates to circumferential flow pumps that are housed in the fuel tank of, for example, an automobile, and supply fuel to the internal combustion engine thereof at a predetermined pressure.
  • An impeller mounted on a circumferential flow pump is provided with a base portion that is fitted to a motor rotor, a vane portion that is formed outer-circumferentially on the base portion, and an outer ring portion that is formed outer-circumferentially on the vane portion.
  • impellers have being developed for the purpose of raising efficiency or lowering noise.
  • the vane portion is made thinner, and that fiber-reinforced polyphenylene sulfide(PPS), being excellent in moldability and dimensional stability, is used.
  • PPS polyphenylene sulfide
  • thermosetting resin such as a phenolic resin
  • the present invention is made in order to solve above-described problems and provide a circumferential flow pump, in which the impeller mounted on the circumferential flow pump is made of fiber-reinforced PPS, so as to curb the quantity of swelling by alcohol and toluene contained in the fuel, so that the impeller is prevented from locking.
  • a circumferential flow pump that feeds into an internal combustion engine, fuel from a fuel tank, includes:
  • the impeller is made of fiber-reinforced PPS and composed of a base portion fitted to a motor rotor,
  • an outer ring portion provided outer-circumferentially on the vane portion, and the vane portion is composed of a plurality of vanes arranged radially protruding straightly from the base portion and each vane includes a bend; and furthermore, given that a projected area of the entire vane portion is S 1 , that of the ring portion, S 2 , that of the base portion, S 3 , when the impeller is projected from a direction along the shaft of the motor rotor, the ratio of S 3 to S 1 is made to fall between 9:1 and 15:1, and the ratio of S 2 to S 1 is made to fall between 0.10:1 and 0.13:1.
  • the quantity of swelling by alcohol and toluene contained in the fuel can be curbed, so that a circumferential flow pump can be provided in which the impeller is prevented from locking.
  • FIG. 1 is a partially sectional elevation view illustrating a circumferential flow pump in Embodiment 1;
  • FIG. 2 a and FIG. 2 b are perspective views illustrating the impeller in Embodiment 1;
  • FIG. 2 a is a whole view thereof, and
  • FIG. 2 b is a partially sectional view thereof;
  • FIG. 3 is a characteristic diagram showing the swelling quantity of the impeller by alcohol and toluene.
  • FIG. 1 is a partially sectional elevation view illustrating a circumferential flow pump in Embodiment 1.
  • the circumferential flow pump 1 includes: a disc-shaped impeller 2 fitted to the motor rotor 3 ; and a pump-housing 7 , composed of a pump cover 5 and a pump base 6 for housing the impeller 2 .
  • a thrust bearing 5 a is placed at the center thereof for bearing in the thrust direction the shaft of the motor rotor 3
  • an inlet 5 b is provided at the bottom of the cover for leading from a fuel tank, fuel into the impeller 2 .
  • a metal member 6 a is placed for bearing the rotating shaft of the rotor 3 .
  • the fuel is led from the inlet 5 b into the pump room by the rotation of the impeller 2 .
  • the fuel is sent from a spout 4 to the internal combustion engine.
  • a clearance 7 a is provided between the impeller 2 and the pump-housing 7 .
  • FIG. 2 a and FIG. 2 b are perspective views illustrating the impeller 2 ; FIG. 2 a is a whole view thereof, and FIG. 2 b is a partially sectional view thereof.
  • the impeller 2 includes a base portion 2 a fitted to the motor rotor 3 , a vane portion 2 b formed outer-circumferentially on the base portion 2 a , and an outer ring portion 2 c formed outer-circumferentially on the vane portion 2 b .
  • an insertion hole 2 f being shaped into the capital letter D, is formed for being fitted to the shaft of the rotor 3 .
  • the vane portion 2 b is composed of a plurality of vanes arranged radially protruding straightly from the base portion 2 a .
  • the vanes on the vane portion 2 b are molded into less than 0.5 mm in thickness, and each vane has a bend 2 e , which is shown in FIG. 2 b.
  • the impeller 2 is formed by injection molding with fiber-reinforced PPS in which a reinforcing material, such as glass fiber, is used.
  • a reinforcing material such as glass fiber
  • the glass-fiber-reinforced PPS is in a molten state of high temperature, and the PPS is injected into a mold portion for the base portion 2 a , and passing through that for the vane portion 2 b , then is injected into that for the outer ring portion 2 c.
  • a projected area of the entire vane portion 2 b is S 1
  • that of the ring portion 2 c , S 2 that of the base portion 2 a , S 3
  • the ratio of S 3 to S 1 is made to fall between 9:1 and 15:1.
  • the ratio of S 2 to S 1 is made to fall between 0.10:1 and 0.13:1.
  • the glass-fiber-reinforced PPS injected into the mold portion for the base portion 2 a fills uniformly the portion and then passes, with a constant high pressure, through that for the vane portion 2 b , which can keep, even at the bends, the randomness of fiber orientation relatively high. Then, pressure is removed from the fiber; thereby, the PPS flowing into the mold portion for the outer ring-portion 2 c , from that for the vane portion 2 b also obtains a relatively high randomness of the fiber orientation.
  • FIG. 3 is a characteristic diagram showing the swelling quantity of the impeller 2 by alcohol and toluene contained in fuel with respect to the ratio of the projected area S 3 of the base portion 2 a to the projected area S 1 of the entire vane portion 2 b and the ratio of the projected area S 2 of the outer ring portion 2 c to the area S 1 , as a parameter.
  • the swelling quantity is curbed in the region that the value of S 3 /S 1 falls between 9 and 15 and that of S 2 /S 1 falls between 0.10 and 0.13.
  • the swelling quantities of the vane portion 2 b and the ring portion 2 c can be curbed due to a relatively-high fiber randomness in those portions.
  • the swelling quantity is curbed most in the region that the value of S 3 /S 1 falls between 12 and 14 and that of S 2 /S 1 falls between 0.10 and 0.13.
  • the impeller 2 can be prevented from locking without widening the clearance 7 a between the impeller 2 and the pump-housing 7 .
