Definitions

  • the invention relates to a pond pump with impeller rotating in a pump housing about an axis of rotation, wherein the pump housing has a suction inlet arranged axially to the impeller, a pressure outlet arranged radially to tangentially to the impeller for the water to be conveyed and a housing section between suction inlet and pressure outlet, wherein the impeller a radially arranged circular disc with wings arranged on one side and wherein the housing portion of the associated with the wings open side of the impeller assigned and formed as a flat mating plate and wherein between the wings, the circular disk and the mating disk flow channels are formed.
  • Such a pump is out of the US 5,713,719 , which is considered to be the closest prior art, known as a centrifugal or centrifugal pump with an open impeller.
  • the impeller has impeller vanes. Between the pump impeller blades, a circular disk carrying the impeller blades and a housing portion, flow channels are formed. These flow channels increase in their cross section from the radial inside to the outside.
  • centrifugal pump with a free-flow impeller in which flow channels between complete pump blades, which extend from the axis of rotation of the impeller to the radial periphery, and short pump blades, which are arranged in the outer ring portion of the impeller, are formed. These flow channels also increase from the inside to the outside in their cross-section.
  • centrifugal pumps are generally known in the art, which have a rotating impeller for the promotion of water.
  • the pumps are usually immersed in the water to be pumped (submersible) used.
  • a pipe for sucking the water to be pumped can be arranged on the suction side.
  • the pump For dry installation, the pump must be placed next to the pond below the water level.
  • the pumped water is conveyed via a pipeline, for example, to a pond filter, a fountain, an applied watercourse or the like.
  • Centrifugal pumps operate on a hydrodynamic delivery principle, wherein the water to be conveyed fed near the axis of rotation of the impeller, entrained by the rotating impeller with its wings arranged thereon and forced to a circular path. Due to the centrifugal force of the rotating water on the circular path, the water is forced radially outward. Accordingly arises near the axis of rotation of the water supply Negative pressure (suction side) and at the periphery of the impeller an overpressure (pressure side).
  • Centrifugal pumps are very reliable and can be used in electrically fully encapsulated design as submersible pumps, for example, for swimming ponds. Furthermore, with appropriate design of the impeller and associated pump housing water can be promoted with solids, without the blockages are to be feared.
  • the impeller is designed as a so-called free-flow impeller, so that the permissible solids size can be, for example, 6 mm (ball passage). Thus restrict only on the suction side coarse filter elements with a corresponding mesh size, the flow rate.
  • the object of the invention is therefore to optimize a generic centrifugal pump accordingly.
  • a centrifugal pump with an open impeller has an improved efficiency when formed between the wings flow channels a cross section which decreases in the flow direction from the radial inside to the outside.
  • the cross-sectional constriction in the flow channels in the radial direction from the axis of rotation to the outside causes an increase in the centrifugal forces and thus in the hydrodynamic delivery pressure.
  • the reduction in the flow channel cross section is preferably 15% to 40%, preferably 20% to 35%.
  • a flow channel cross-section reduction can preferably be realized in that the counter-rotating plate in the form of a wide-open conical surface section is formed at an angle ( ⁇ ) between 5 ° and 20 ° to the radial plane aligned with the axis of rotation in the direction of the impeller ,
  • the flow channel cross-section reduction is achieved in that the circular disc of the impeller in the form of a wide-open cone sheath is formed at an angle ( ⁇ ) between 5 ° and 20 ° to the rotational axis aligned to the radial plane in the direction of the mating plate.
  • the efficiency of the pond pump is increased when the measured axially to the rotational axis height of the blades of the impeller decreases from the radially inner side to the outer side, so that the open side of the impeller is arranged with a substantially uniform gap distance from the mating plate. If the gap dimension is less than or equal to 1 mm, preferably less than 0.5 mm, pressure losses due to short-circuit flows between the impeller and the counter-rotating plate are reliably avoided.
  • the height of the wings on the radial outer side is greater than or equal to the width of the flow channels.
  • the efficiency of the pump is further improved. Presumably, this improvement in efficiency should result from a further reduction of turbulence and thus flow losses.
  • blockages are avoided by this design.
  • the width of the flow channels should be greater than or equal to the max. allowable grain size, for example, greater than or equal to 6 mm, be formed.
  • the wings have a crescent-shaped cross-section in the radial direction to the axis of rotation, a hydrodynamically particularly effective flow channel geometry is formed between the crescent-shaped vanes. Due to the crescent-shaped cross section, the wings have a high intrinsic stability, so that the impeller has a long service life.
  • the mating plate is an integral part of the pump housing.
  • the pump housing and / or the impeller are preferably produced from acrylonitrile-butadiene-styrene (ABS), modified polyphenylene oxide (PPO, so-called "Noryl") and / or polyoxymethylene / polyacetal (POM).
  • ABS acrylonitrile-butadiene-styrene
  • PPO modified polyphenylene oxide
  • POM polyoxymethylene / polyacetal
  • the pump housing with integrally molded mating plate made of dimensionally stable and inexpensive ABS plastic.
  • the impeller can be made both from ABS plastic in sufficient dimensional stability and strength as a low-cost component or for particularly heavy loads of PPO or POM plastic.
  • an asynchronous motor with stainless steel can in a housing provided in which a sealed encased in stainless steel rotor is mounted, which forms a removable from the housing running unit with the impeller.
  • the running unit is rotatably mounted in a ceramic bearing in the housing.
  • FIG. 1 is a sectional view through an axial plane of a pond pump with a pump housing 1 and a rotating about a rotation axis X impeller 2 shown.
  • a drive unit consisting of an electric motor arranged in a housing, preferably an asynchronous motor, can be attached to the side represented by arrow Y.
  • the impeller 2 is driven to rotate about the rotation axis X.
  • the pump housing 1 has a suction inlet 11, which is disposed opposite to the drive side Y coaxial with the axis of rotation X. At the suction inlet 11 a nozzle is formed, on which a suction line for supplying water to be conveyed can be placed. When using the pump as a submersible pump, the water can also be fed directly into the suction inlet 11. The water flow on the suction side is indicated by arrow Ws.
  • the pump housing 1 together with the drive unit Y, not shown, a housing of the rotary-driven impeller 2 to at Rotation of the impeller 2 to cause a hydrodynamic promotion of the water.
  • a mating plate 12 is formed between the axially arranged to the rotation axis X suction inlet 11 and the peripheral impeller 2 torus-shaped collecting chamber 13, a mating plate 12 is formed.
  • the mating plate 12 forms an annular surface, which in the in FIG. 1 illustrated embodiment is designed as a wide open cone shell portion with an angle ⁇ of approximately 10 ° to the radial plane in the radial direction and the drive side Y directed inclined.
  • the impeller 2 has an aligned in a radial plane to the rotation axis X circular disc 22, are formed on the axially projecting in the direction of the suction side wings 21.
  • FIG. 2 is the impeller 2 in a plan view from the direction of the suction side Ws (see Fig. 1 ).
  • This in FIG. 2 illustrated impeller 2 has eight in its cross section in the radial axis X to the rotation axis sickle-shaped wings 21. Between the vanes 21, eight flow channels 23 are formed, which have a substantially constant width b of, for example, 6 mm between adjacent vanes 21, 21.
  • a central bore 24 is provided with integrally formed shaft 25 on the impeller 2.
  • the open side of the impeller 2 is located directly opposite to the mating plate 12 of the pump housing 1. Accordingly, the free projecting ends of the wings 21 of the angled ⁇ by the angle mating plate 12 adapted so that between the free upper edge of the wing 21 and the mating plate 12 results in a substantially uniform gap s of, for example, 0.5 mm.
  • the impeller 2 rotates about the axis of rotation X.
  • the impeller 2 is driven by a drive unit Y, not shown. Due to the rotational movement of the impeller 2 with the wings 21 formed thereon, water present on the suction side Ws is sucked due to a negative pressure arising in the center of the impeller 2 and brought to a circular path via the flow channels 23.
  • the centrifugal acceleration of the water in the flow channels 23 leads due to centrifugal force to a pressure increase and thus to the hydrodynamic delivery of the water to the pressure outlet 14 on the pressure side where the pump.
  • the small gap s of about 0.5 mm reliably prevents a flow short circuit, so that the pump works very effectively.
  • the formation of the flow channels 23 with a substantially constant width b equal to 6 mm allows a blockage-free promotion of laden with solid particles up to a particle size of 6 mm water through the pump. Since the height h of the wings 21 at the peripheral outlet of the flow channels 23 at least equal to the width b, so b is less than or equal to h, clogging of the flow channels is also avoided with respect to the height dimensioning.
