Definitions
- the invention relates to a liquid ring machine according to the preamble of claim 1.
- Such a liquid ring machine is through DE-A-43 05 424 known. Due to the relative position of the impeller to the inner contour of the machine housing of the liquid ring machine become the performance data of the machine influenced. Depending on the peripheral speed of the Impeller, the pressure ratio of the machine or its Different installation positions of the operating fluid Impeller compared to the machine housing to better or result in poorer machine performance data. Further these data are due to manufacturing tolerances influenced.
- the invention has for its object a liquid ring machine of the generic type so that the relative position of the impeller and machine housing to each other can be easily adjusted to the best possible Get machine performance data.
- a fixing device is provided by which the machine housing opposite the side plates or the control discs in a pivoted in the circumferential direction Position is fixable.
- the fixing device is thus at Setting up the machine housing in an optimal position for Easily accessible impeller.
- Fixing the machine housing in the set Location is possible in a simple manner that the Fixing device from on the side plates or the control discs and the peg holes provided in the machine housing and is in these insertable pins.
- At least one of the other fixable parts several in the circumferential direction from each other spaced peg holes provided.
- the number of adjustment stages can be increased in that both on the machine housing and on the side plates or the control disks each in the circumferential direction spaced-apart pegging holes are provided, the peg holes provided on the machine housing have a different distance from each other than that of the Side shields or peg holes provided on the control discs. Due to the different spacing of the peg hole on the machine housing and the side plates or Control discs are between the dimensions of each Distance setting levels reached.
- the machine housing can be adjusted continuously thereby achieve that the machine housing by clamping in its position in relation to the control discs or side plates is fixable.
- the impeller 5 is centered in the axial direction by itself Central wall extending over the entire circumference of the impeller 5 9, the radial direction from the impeller hub to the free ends of the blades 4 of the impeller 5 are sufficient, divided.
- the middle wall 9 is lying in one plane a concentrically enclosing the impeller 5, with the Machine housing 1 fixed partition 10 intended. Between the middle wall 9 and the intermediate wall 10 there is an operational gap 11. Through the middle wall 9 and the partition 10 is a subdivision of Given work space in two sub-work rooms 12.
- the machine housing 1 is one outside its center axis 8 pivot point 13 pivotable arranged.
- To the machine housing 1 in the respective To be able to fix swivel position are in the range of Outside circumference of the control disks 3 peg holes 14 and a flange ring 16 of the machine housing 1 peg holes 15 attached.
- the arrangement of the pin holes 14 and 15 is taken so that when the machine housing is pivoted 1 around the pivot point 13 after a certain one Swivel angle, a peg hole 14 of the control disks 3 with a peg hole 15 of the machine housing 1 for Cover comes.
- a pin 17 into the covering holes 14 and 15 can do that Machine housing 1 is then fixed in the respective pivot position become.
- the circumferential distance of the peg holes 14 the control discs 3 differs in size from the size of the circumferential distance of the Machine housing 1 provided pin holes 15. This there is the possibility of the machine housing 1 by one smaller than the respective spacing of the peg holes 14 or 15 to pivot the corresponding angle.
- the described way of setting the relative location of Impeller 5 and machine housing 1 is also in liquid ring machines with divided by an intermediate wall 10 Machine housing 1 of particular advantage.
- the Pivoting of the machine housing 1 around the outside of the Center axis 8 of the machine housing 1 lying pivot point 13 results in a more even change between the intermediate wall 10 and the impeller 5 or its central wall 9 existing gap 11.
- the partition 10 can thus be fixed be 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 Figure 2 of the impeller 5 and Machine housing 1 can be referred to as zero position, because that Impeller 5 and the machine housing 1 aligned with each other are that the gap 11 between the impeller 5 and the Partition wall 10 over the entire circumference of the impeller 5 is the same in all places.
- the representation according to FIG. 3 shows a pivoting of the machine housing 1 in a clockwise direction and the illustration according to FIG. 4 shows a pivoting counter clockwise.
- the pivot point 13 can by one at the corresponding Circumferential location of the liquid ring machine in the control disc 3 or in the side plate 2 and the wall of the Machine housing 1 or the flange ring 16 engaging Axle pin are formed.
