Definitions

  • An impeller with a star shape is arranged in side channel pumps Wings and open wing spaces closely by one Surround the housing that axially next to the impeller to the impeller forms an open side channel in which the medium is promoted by impulse exchange with the impeller.
  • the side channel is also used in the known pumps of this type arranged on the side of the impeller on which the medium is fed in and out. This simplifies media management, because the inlet and outlet openings are directly connected to the side channel keep in touch.
  • the special bypass channel is expediently in the area the impeller level is completely separated from the housing space, in which the impeller rotates.
  • the invention wants Do not exclude designs in which the channel to Open impeller but is designed so that the largest Part of the medium flow during the bypass around the impeller around is not caught by the impeller.
  • the bypass channel should tangentially from the side channel according to the invention be led out and axially outside the impeller space be deflected to pass over to the other side of the housing.
  • peripheral pumps an outlet channel to be arranged radially outside the impeller
  • US-A-4508492, JP-A-1177492 Abstract, JP-A-1147196 Abstract, JP-A-1147195 Abstract, FR-A-2237073, DE-A-3844158 It is known for peripheral pumps, an outlet channel to be arranged radially outside the impeller.
  • Peripheral pumps fundamentally different design requirements than with side channel pumps.
  • peripheral pumps namely the channel in impulse exchange with the impeller arranged so that he the impeller on both sides and surrounds symmetrically around the circumference. This inevitably results in that the removal of the medium to reduce losses radial and possibly tangential.
  • the experience with peripheral pumps also did not expect the medium discharge to the area lying radially outside of the impeller could be associated with noise reduction because of peripheral pumps an even higher noise level than conventional ones Have side channel pumps.
  • the housing parts 1 and 2 include an impeller space, in which the impeller 3 on a shaft, not shown circulates.
  • the side channel 4 is formed to the wings 5 of the impeller 3 is open.
  • Its entry end 6 lies opposite that formed in the housing part 2 Entry opening 7, so that the entering through the opening 7 Medium through the spaces between the wings 5 to the side channel 4 can reach.
  • the inlet opening 7 is connected upstream Suction spaces connected through which the medium to the Entry opening 7 arrives.
  • the side channel is in area 8 guided tangentially to the outside, so that a bypass duct 9, 10 is created.
  • This is initially with its part 9 in housing part lying axially on one side of the impeller 3 1. He then arrives with his part 10 in a radially outside the diameter of the impeller 3 lying area. Radial outside the impeller it leads with an axial direction component to the other side of the impeller, the End of the bypass duct 10 located in the housing part 2 Exit opening 12 forms.
  • part 9 of the Bypass channel in the housing part 10 the medium in Redirected axial direction. Parts 9 and 10 of the bypass channel are separated from the impeller space by a housing tongue 11, so that further influencing the medium flow by the impeller in this area.
  • the pressure chamber can also be formed in the housing part 2, which is then designed to be larger than it is Drawing shows. Or it is on the disc-shaped housing part 2 another, containing the pressure chamber and the suction chamber, special housing part connected in the Drawing is not shown.
  • the bypass channel can be designed as a diffuser. A Deflection of the channel 9, 10 in the axis-parallel direction generally not required. Rather, the channel part 10 expediently aligned obliquely in the circumferential and axial directions. For these reasons, the outlet opening 12 in Housing part 2 expediently with considerably larger Cross section (measured parallel to the impeller plane) than that Side channel (measured in the longitudinal plane) equipped. In the As a rule, the outlet opening should be larger by a factor of 1.5 to 3 than the side channel cross section.
