Definitions

  • the invention relates to a method for positioning a cover plate of a pump according to claim 1 and a pump according to claim 12.
  • the so-called inner cover plate, a second cover plate, the so-called outer cover plate opposite the impeller must be positioned and attached to a pump housing during assembly of the pump.
  • the arrangement of the outer cover plate creates a delivery channel of the pump, whereby a conveying or pumping of the pumped medium is made possible.
  • the cover plate should be positioned at a certain distance from the impeller, and it is particularly important that a uniform distance is set via the impeller. The setting of a uniform distance is particularly difficult because the positioning is done by means of several screws whose adjustment must be coordinated.
  • a step 1 the cover disk and the pump housing are positioned relative to one another so that the cover disk comes into contact with the impeller and achieves an end position of the cover disk only a target distance in the axial direction between the cover plate and the impeller is set.
  • the cover disk is thus so arranged opposite the pump housing, that it only has to be positioned in the axial direction.
  • a first adjusting screw is screwed into a first, in particular designed as a through hole threaded bore of the cover plate until a screw end of the first screw comes to a contact surface of the pump housing to the plant.
  • the first set screw is only screwed in so far that the cover disc still rests on the impeller and does not lift off yet.
  • the screwing of the screw is done in particular by hand, ie without the use of a tool, for example in the form of a wrench.
  • a marking is affixed to the cover disk or to the pump housing, which designates a position of a first marking, in particular on a circumference of the first adjusting screw.
  • the marking takes place in particular by means of a pen. But it is also possible that the label is scratched or done by means of a sticker.
  • the first screw is further screwed in until a second mark, in particular on the circumference of the first screw the said label on the cover plate or the pump housing reaches and thus the desired distance between the cover plate and the impeller is set.
  • Steps 2 to 4 are carried out for at least one second adjusting screw and in particular also for a third and fourth adjusting screw, or for all other adjusting screws. It can also be used more than four screws.
  • the screws have the same thread, especially the same thread pitches.
  • the first and second marks on the screws are arranged equal to each other, in particular, a relative angular position of the two marks is identical.
  • all screws are rotated in step 4 by the same angle, which leads to an identical pitch of each screw to an identical displacement of the cover plate in the axial direction relative to the pump housing.
  • a suitable choice of the thread pitch and the arrangement of the first and second mark on the screws a desired desired distance between the cover plate and the impeller can be set. In particular, only identical adjusting screws are used.
  • step 1 is carried out and then step 2 for all adjusting screws, then step 3 for all adjusting screws and then step 4 for all adjusting screws.
  • step 2 for all adjusting screws
  • step 3 for all adjusting screws
  • step 4 for all adjusting screws.
  • one or all screws are screwed into the threaded holes of the cover plate even before performing step 1.
  • the screws are in this case designed in particular and have a corresponding slope that for adjusting the target distance, the screws must be screwed in step 4 between 20 ° and 90 °, in particular by 70 °.
  • the second mark on the set screws between 20 ° and 90 °, in particular offset by 70 ° against the screwing offset to the first mark.
  • the first and second markings are designed as notches on the circumference of the adjusting screws and have a different shape, wherein a notch may in particular have a V-shaped, a rectangular or a rounded shape.
  • the notches extend in particular in the axial direction over the entire external thread of the adjusting screws.
  • the two markings can be distinguished particularly well if they have different colors.
  • the screws have a third and a fourth mark, wherein the third mark corresponding to the first mark and the fourth mark is carried out according to the second mark and the arrangement or the angular offset of the fourth mark to the third mark of the arrangement or corresponds to the angular offset of the second mark to the first mark.
  • the markings do not necessarily have to be arranged on the circumference of the set screws. You could for example also be arranged on a screw head of the screws.
  • the screws are designed as sleeves in which fasteners can be arranged, for example in the form of solid mounting screws, by means of which in a step 5, the cover plate is attached to the pump housing.
  • step 5 is carried out in particular only when step 4 has been carried out for all adjusting screws. For a particularly simple and secure attachment of the cover plate on the pump housing is possible.
  • the desired distance between the cover plate and the impeller between 0.1 and 0.3 mm, in particular between 0.15 and 0.25 mm. This allows a particularly high efficiency of the pump.

  • the lock nut is tightened after reaching the desired distance against the side facing away from the housing of the cover plate.
  • a pump having a pump housing, an open impeller disposed therein and a cover plate for the impeller, wherein the cover disc has at least two threaded holes, in each of which a screw is arranged, by means of which, starting from a plant of the cover disk on Impeller is a desired distance between the cover plate and the impeller is adjustable, wherein at installation of the cover plate on the impeller screw ends of the screws only contact surfaces of the pump housing and at least during the setting of the desired distance between the cover plate and the impeller the cover plate or the pump housing markings have, which at installation of the cover plate on the impeller a position of a first mark, in particular on a circumference of the set screws and set target distance between the cover plate and impeller a position of a second mark especially at the periphery of the screws kennz oak, the screws have similar threads and the first and second marks on the screws are arranged equal to each other.

  • the cover plate 16 should be arranged in its end position at a predetermined nominal distance of approximately between 0.1 and 0.3 mm, in particular between 0.15 and 0.25 mm from the impeller 12. If the distance is too small, contact between impeller 12 and cover disk 16 and thus damage may occur. If the distance is too large or uneven, the efficiency of the pump 10 is not optimal.
