Definitions

  • the object of the invention is therefore in a side channel pump with two parallel pump channels and pressure equalization openings in the channel partition improve pump performance.
  • Both pump channels 24a, 24b each have a liquid inlet (not shown) and a liquid outlet assigned, through which the liquid to be pumped into the pump channels 24a, 24b runs in or is pumped out. Furthermore, a pump channel 24b is one Vent hole 42 assigned by the gas bubbles that are in the Have formed liquid, can escape.
  • the pump chambers 32a, 32b of the two pump channels 24a, 24b are each through Channel partitions 34 separated from each other in the radial median plane of the Pump wheel 12 lie.
  • Each channel partition 34 faces the one in FIG Circumferential direction of the front blade wall 30 is adjacent Pressure compensation opening 36 through which the two parallel to each other Pump chambers 32a, 32b are connected to one another.
  • the Pressure equalization opening 36 adjoins the leeward side 38 of the respective one Blade wall 30, but not on the windward side 40 of the other Blade wall 30 of the relevant pump chamber 32a, 32b.
  • the Pressure equalization opening 36 is radially approximately in the middle of each Pump chamber 32a, 32b arranged, as can be seen in Fig. 2.
  • the blade walls 30 are at an angle ⁇ of 20 ° to the windward side inclined, as shown in Fig. 3.
  • the vent hole 42 in the housing half 16 is the half-channel 26b provided by the gas bubbles in the liquid from the pump channel 24b can exit.
  • a constant pressure compensation takes place through the pressure compensation opening 36 between all mutually parallel pumping chambers 32a, 32b.
  • Vent hole 42 occurs in both pumping chambers 32a, 32b accumulated gas volume from the pump channels 24a, 24b, the Gas bubbles from the vent hole half channel 28a through the Wander pressure equalization opening 36.
