Definitions

  • the invention relates to a liquid ring machine according to the preamble of claim 1.
  • Such a liquid ring machine is known from DE-A-43 05 424.
  • the performance of the machine is influenced by the relative position of the impeller to the inner contour of the machine housing of the liquid ring machine.
  • the pressure ratio of the machine or its operating fluid requirement different installation positions of the impeller relative to the machine housing can lead to better or worse performance data for the machine.
  • these data are influenced by manufacturing tolerances.
  • the invention has for its object to design a liquid ring machine of the generic type so that the relative position of the impeller and machine housing can be adjusted to each other in a simple manner to obtain the best possible performance data of the machine.
  • a control device is provided, possibly connected to these control disks and the machine housing, by means of which the machine housing can be fixed in a position pivoted in the circumferential direction relative to the side plates or the control disks.
  • the fixing device is thus easily accessible when setting up the machine housing in an optimal position to the impeller.
  • the fixing of the machine housing in the respectively set position is possible in a simple manner in that the fixing device consists of pin holes provided on the side plates or the control disks and the machine housing and pins that can be inserted into them.
  • At least one of the mutually fixable parts is provided with a plurality of spacing holes spaced apart in the circumferential direction.
  • the number of adjustment stages can be increased by providing a plurality of pegging holes spaced apart in the circumferential direction both on the machine housing and on the side plates or the control disks, the pegging holes provided on the machine housing being at a different distance from one another than those on the side plates or the bores provided on the control disks. Due to the different spacing of the peg hole on the machine housing and the side plates or the control disks, adjustment levels lying between the dimensions of the respective spacings are achieved.
  • the machine housing of a liquid ring machine is designated by 1. On both end faces of the machine housing 1, side shields 2 are arranged, between which control discs 3 are inserted and the machine housing 1. The machine housing 1 is covered on the end face by the control disks 3 and the working space of the liquid ring machine is thus formed within the machine housing 1.
  • the impeller 5 of the liquid ring machine provided with blades 4 is arranged in this working space.
  • the impeller 5 is mounted via an impeller shaft 6 in the side plates 2 eccentrically relative to the machine housing 1, i.e. the center axis 7 of the impeller shaft 6 is offset from the center axis 8 of the machine housing 1 on one side by the eccentricity e.
  • the impeller 5 is divided in the middle in the axial direction by a central wall 9 which extends over the entire circumference of the impeller 5 and extends in the radial direction from the impeller hub to the free ends of the blades 4 of the impeller 5.
  • a central wall 9 With the central wall 9 lying in one plane, an intermediate wall 10 is provided which concentrically surrounds the impeller 5 and is fixedly connected to the machine housing 1.
  • the middle wall 9 and the intermediate wall 10 divide the work space into two sub-work spaces 12.
  • the machine housing 1 is arranged to be pivotable about a pivot point 13 lying outside its central axis 8.
  • 3 pegging holes 14 are made in the area of the outer circumference of the control disks and 1 pegging holes 15 on a flange ring 16 of the machine housing.
  • the arrangement of the pegging holes 14 and 15 is such that when the machine housing 1 is pivoted about the pivot point 13 after a certain pivoting angle, a pegging hole 14 of the control disks 3 with a pegging hole 15 of the machine housing 1 is congruent.
  • the machine housing 1 By inserting a pin 17 into the overlapping peg holes 14 and 15, the machine housing 1 can then be fixed in the respective pivot position.
  • the circumferential distance of the peg holes 14 on the control disks 3 differs in size from the size of the circumferential distance of the peg holes 15 provided on the machine housing 1. This makes it possible to machine the machine housing 1 by a smaller than the respective spacing of the peg holes 14 or .15 swivel the corresponding angle.
  • the described type of setting the relative position of impeller 5 and machine housing 1 is also of particular advantage in liquid ring machines with a machine housing 1 divided by an intermediate wall 10.
  • the pivoting of the machine housing 1 about the pivot point 13 lying outside the center axis 8 of the machine housing 1 results in a more uniform change in the gap 11 existing between the intermediate wall 10 and the impeller 5 or its central wall 9.
  • the corresponding setting of the machine housing 1 can thus be compared the impeller 5 can be made without 10 adjustments being necessary on the intermediate wall.
  • the intermediate wall 10 can thus be firmly connected to the machine housing 1. So it's one one-piece design of machine housing 1 and partition 10 possible.
  • the position shown in FIG 2 of the impeller 5 and the machine housing 1 can be referred to as zero position, since the impeller 5 and the machine housing 1 are aligned with each other so that the gap 11 between the impeller 5 and the intermediate wall 10 over the entire circumference of the impeller 5 is the same in all places.
  • the illustration according to FIG. 3 shows a pivoting of the machine housing 1 in the clockwise direction and the illustration according to FIG. 4 shows a pivoting counterclockwise.
  • the pivot point 13 can be formed by an axle pin which engages in the control disk 3 or in the side plate 2 and the wall of the machine housing 1 or the flange ring 16 at the corresponding circumferential point of the liquid ring machine.
