Definitions

  • the present invention relates to a gear pump and a method for constructing it.
  • Gear pump means a pump in which the change in volume induced by the meshing of two bodies is exploited to transfer energy to a fluid passing through the pump.
  • gear pumps comprising:
  • gear pumps One drawback of gear pumps is tied to the need to reinforce the delivery conduit, since greater pressures occur in that zone. In this way both stress and deformations are reduced to the advantage of correct functioning, but the overall dimensions of the pump are increased because of the larger thicknesses required.
  • a known gear pump is disclosed by WO2009/126223 .
  • the technical task at the basis of the present invention is to provide a pump which enables the overall dimensions to be reduced without penalising the correct functioning and reliability thereof.
  • the reference number 1 indicates a gear pump.
  • Said pump 1 comprises a compartment 20 housing said gears which transfer energy to a fluid crossing the pump 1.
  • the gears comprise two cogwheels that reciprocally mesh and are positioned in the housing compartment 20.
  • One of the gears could possibly have external teeth and the other internal teeth.
  • the two gears could be rolling bodies that interact with each other, but do not have an involute profile (for example, a lobe pump).
  • the pump 1 also comprises a first conduit 21 which develops from the housing compartment 20.
  • said first conduit 21 is a delivery conduit.
  • the first conduit 21 is thus used for discharging the fluid under pressure from the compartment 20.
  • the pump 1 comprises a first stiffening rib 31 that crosses the first conduit 21.
  • the first stiffening rib 31 divides the flow of fluid into at least two parts. The two parts reconverge downstream of said first rib 31.
  • the first rib 31 thus serves to stiffen the delivery conduit, minimising the tensions of the material and consequently the deformations without oversizing in thickness the walls of the first conduit 21. It is thus possible to minimise the outer dimensions of the pump 1.
  • the first stiffening rib 31 comprises a fin 310 having an aerodynamic profile. This enables pressure drops to be minimised. An even more important advantage may be had in the case of a reversible pump, as better explained below.
  • the pump 1 advantageously comprises a second conduit 22 which terminates in said housing compartment 20.
  • the second conduit 22 is an aspirating conduit.
  • the pump 1 also comprises a second stiffening rib 32 crossing said second conduit 22.
  • the pump 1 is reversible. It can thus also function in a second operating mode in which the first conduit 21 becomes an aspirating conduit and the second conduit 22 becomes a delivery conduit.
  • the presence of the rib 32 also in the second conduit 22 is thus important.
  • the second conduit 22 can also become a delivery conduit and therefore be subject to considerable stresses due to the fluid under pressure.
  • the second stiffening rib 32 comprises a fin 320 having an aerodynamic profile.
  • this feature serves to minimise the pressure drops on the aspirating side in order to reduce the risk of cavitation (in the first operating mode the second rib 32 operates under aspiration and the aerodynamic profile helps for that purpose).
  • first conduit 21 and the second conduit 22 comprise two ports 23, 24 which lie side by side on a same wall of the pump 1, turned outward. Internally of the pump the first and the second conduit 21, 22 extend side by side.
  • the two ports 23, 24 of the first and the second conduit 21, 22 could be located on two distinct walls of the pump 1; in particular, they could be lateral.
  • first conduit 21 and the first rib 31 are in a single monolithic body.
  • the second conduit 22, the second rib 32 and at least a part of the housing compartment 20 are in a single monolithic body.
  • the single monolithic body is advantageously made of cast iron.
  • the single monolithic body also defines an external casing that delimits at least in part the pump 1 from the outside.
  • the first conduit 21, the second conduit 22, the first and second rib 31, 32 and at least a part of the housing compartment 20 are symmetrical with respect to a median plane 4 interposed between the first and the second conduit 21, 22.
  • the first rib 31 comprises:
  • the first and the second surface 311, 312 comprise a portion 315 in which they are reciprocally divergent and a portion 316 in which they are reciprocally convergent.
  • One of the two parts of the flow divided by said first rib 31 skims over the first surface 311 and the other over the second surface 312.
  • the first conduit 21 comprises a first delimiting wall 25 that faces the first surface 311 and defines a concavity turned toward the first surface 311.
  • the first conduit 21 comprises a second delimiting wall 26 of that faces the second surface 312 and defines a concavity turned toward the second surface 312.
  • the first rib 31 connects to remaining parts of the monolithic body at a first and a second end 317, 318 thereof, which are reciprocally opposite.
  • the first end 317 is closer to an outer surface of the pump than the second end 318.
  • At least a transversal section that is intermediate with respect to the first and the second end 317, 318 has a smaller surface than a surface of the transversal section measured at the first and second end 317, 318.
  • the intermediate section has a chord and/or average thickness that is/are smaller than those of the transversal section measured at the first and the second end 317, 318.
  • the first rib 31 has a larger transversal section at the first end 317 than at the second end 318.
  • the invention thus conceived enables multiple advantages to be obtained. First of all, it permits a reduction in the overall dimensions of the pump 1.
  • the first rib 31 (positioned in the first conduit 21) enables the delivery side of the pump 1 to be stiffened without reinforcing the thickness of the conduits.
  • the aerodynamic shape of the fin makes it possible to avoid significant pressure drops on the aspirating side (and the consequent risk of cavitation) in the event that the pump functions in a reversible mode and the first conduit 21 thus acts as an aspirating conduit.
  • the invention thus conceived is susceptible of numerous modifications and variants, all falling within the scope of the inventive concept characterising it. Moreover, all of the details may be replaced with technically equivalent elements. In practice, all of the materials used, as well as the dimensions, may be of any type, according to need.
