Definitions

  • the present invention relates to pump units comprising, from the bottom up, a vertical axis wheel driven in rotation by a motor above it.
  • the engine heats up. It must be cooled, especially for a pump unit intended to be submerged, fortuitously the top corresponding to the engine is no longer.
  • the invention provides a pump unit with vertical axis wheel comprising a body from which a discharge pipe and the upper part of the lateral surface is surrounded by a jacket at a distance between them.
  • a pump unit with vertical axis wheel comprising a body from which a discharge pipe and the upper part of the lateral surface is surrounded by a jacket at a distance between them.
  • an annular channel is supported by spacers on the upper face of the body and is delimited by a bottom, an inner face spaced from the axis and an outer face.
  • the outer face is at a greater distance from the axis than the inner face.
  • the top edge of the inner face is lower than the top edge of the outer face.
  • a bypass duct puts the discharge tubing in communication with the channel.
  • the water discharged by the pump unit is driven by the bypass duct into the channel. It fills up to overflow by the inner side, lower than the outer face.
  • the water flows into the basin formed between the bottom of the canal and the upper face of the body until it comes in between and flow along the body while cooling it.
  • the flow is thus made very homogeneous and substantially laminar, which is excellent for the good cooling of the body.
  • a pressure reducing diaphragm is mounted in the bypass duct, so that the water arrives in the channel with less pressure and thus without splashing.
  • the channel is covered by a cover, through which the bypass duct passes and to which the jacket is attached.
  • the shirt is in particular supported directly by the lid.
  • the peripheral outer face of the channel is in line with the outer peripheral surface of the body, which allows the use of water at best for cooling.
  • the single figure of the appended drawing is a truncated sectional view of a pump unit according to the invention.
  • the group comprises a body 1 surrounding a motor 2, whose shaft drives a wheel 3 of axis XX 'vertical.
  • Body 1 leaves a discharge pipe 4.
  • a bypass pipe 5 From the discharge pipe part a bypass pipe 5, on which are mounted a strainer 6 and a diaphragm 7.
  • the bypass duct 5 opens into a channel 8 delimited by a bottom 9, a peripheral inner face 10, a peripheral outer face 11 and a cover 12.
  • the top edge of the inner face 10 is lower than the high edge of the outer face 11.
  • the face 10 is closer to the axis XX 'than the face 11.
  • the cover 12 supports a sleeve 13, which extends further down than the upper face 14 of the body 2 and which delimits with the side 1 side
  • the channel 8 is supported on the upper face 14 of the body 2 by four spacers 16. It is thus defined, between the bottom 9 of the annular channel 8 and the upper face 14 of the body, a plenum of the water.
  • water is diverted from the pipe 5, which arrives in the channel 8. It overflows from the top of the edge of the inner face of the channel, the overflow already leading to a tranquilization, for to reach the basin, which tranquilizes even more, before flowing substantially laminarly in the interval 15 and cooling the outer face 1 of the body 2.
  • the outlet pipe 4 has a diameter of 560 mm
  • the basin has a height of 11 mm
  • the gap is 4 mm
  • the diameter of the diaphragm is 9.5 mm
  • the pump has a flow rate of 10000 m 3 per hour.
