Definitions

  • the invention relates to a liquid ring compressor with a horizontal shaft and at least one compressor stage which comprises suction and pressure chambers arranged at the side of a delivery chamber and an auxiliary liquid discharge opening.
  • these compressors require an auxiliary liquid for operation, a part of which remains in the compressor even after the compressor has been switched off and at a standstill. This is necessary in order to be able to restart the compressor at a later point in time.
  • Another conceivable reason for removing the auxiliary or operating fluid from the compressor housing may be that it is a very aggressive fluid that chemically attacks the material of the compressor even when it is not running.
  • the liquid ring compressor according to GB-A 310 094, from which the invention is based, does not allow the desired complete emptying of the pump. It does have an emptying opening arranged in the geodetically lowest point of the delivery chamber, by means of which the auxiliary liquid can be emptied from the delivery chamber.
  • the suction and pressure chambers arranged on the side of the delivery chamber are connected to the delivery chamber by inlet and outlet openings. which is considerably higher than the geodetically lowest point of the suction and pressure chambers, so that the complete emptying of the same is not possible through the emptying opening arranged in the delivery chamber.
  • the invention is therefore based on the object of creating a compressor of the type mentioned which can be emptied in a simple and quick manner.
  • the solution according to the invention is that the emptying opening is provided for all the rooms belonging to a stage, and both the suction chamber and the pressure chamber are each connected to the delivery chamber at its geodetically lowest point.
  • the emptying opening is expediently arranged at the conveying stage; however, it is also possible to provide them on the suction or pressure chamber, provided that it is at least as deep as the delivery chamber.
  • the suction space of the compressor stage is delimited at the bottom by a wall directly adjoining the geodetically lowest point of the suction passage between the suction and delivery space.
  • the deep point of the suction passage itself forms the geodetically lowest connection between the suction chamber and the delivery chamber of the compressor stage.
  • connection between the suction and delivery chamber of the compressor is made through a possibly additional hole, it is advantageous to arrange this hole in the geodetically lowest point of the suction chamber so that it connects the gas zone of the delivery chamber with the suction chamber during operation of the compressor.
  • the arrangement in this area ensures that the delivery capacity of the compressor is not impaired in normal operation.
  • the pressure chamber can be delimited at the bottom by a wall which is geodetically arranged directly below the pressure passage or the bores, slots or valves belonging to the pressure passage between the delivery and pressure chambers.
  • the lowest point of the passage or the associated bores or valves again serves as the necessary geodetically low-lying connection between the pressure chamber and the delivery stage, and a further connection can possibly be omitted.
  • the geodetically lowest point of the Pressure chamber a connection hole to the delivery chamber of the compressor can be arranged.
  • a compressor contains spaces which are both a pressure chamber of a preceding and a suction chamber of a subsequent compressor stage, then it is proposed according to the invention to arrange the geodetically deep connection between this space and the delivery chamber of the subsequent stage. It has been found that the connection is easiest to design without influencing the compressor performance.
  • connection bores between the suction and delivery space or pressure and delivery space in geodetically drawn down troughs or pockets of these spaces.
  • shut-off devices By appropriate coupling of these shut-off devices with an existing central discharge opening, simple and problem-free discharge of even multi-stage compressors can then be achieved by only one central discharge drain. Shutting off the connecting line during the operation of the compressor is necessary, however, in order to prevent an overflow of liquid between the different compressor stages and thus a corresponding reduction in performance.
  • the impeller 2 is attached to the shaft 1.
  • the suction cover 3 is the suction-side compressor inlet 4 to the suction chamber 5 of the compressor stage.
  • the pressure port 7 of the compressor with the pressure chamber 8 is located on the pressure cover 6.
  • the impeller runs between the control disk 9 on the suction side and the control disk 10 on the pressure side, which together with the central body 11 form the delivery chamber 12 of the compressor.
  • the only opening 13 for emptying the compressor stage to the outside is provided on this delivery chamber 12.
  • Fig. 2 shows a plan view of the suction-side control disk 9 out of the suction chamber 5 of the compressor.
  • the transfer of the medium from the suction chamber 5 into the delivery chamber 12 takes place through the suction passage 14 in the control disk 9.
  • the suction chamber 5 is delimited at the bottom by a wall 15 which connects directly to the geodetically lowest point of the suction passage 14.
  • a connecting bore 16 in the control disk 9 connects the suction chamber 5 to the delivery chamber 12 at the geodetically lowest point of the suction chamber, this bore being arranged in such a way that, when the compressor is operating, it connects the gas zone of the delivery chamber 12 with the suction chamber 5 connects.
  • Fig. 3 shows a view from the pressure chamber 8 of the compressor out on the pressure-side control disc 10.
  • the pressure passage 17 through which flow medium and part of the liquid flow from the delivery chamber 12 of the compressor into the pressure chamber ß.
  • the pressure chamber 8 itself is delimited at the bottom by a wall 18, at the geodetically lowest point of which a bore 19 additionally connects the pressure chamber 8 to the delivery chamber 12 of the compressor.
  • the bore is located in a geodetically drawn down recess or pocket 20 of the wall 18.
  • the suction port 4 is located on the suction cover 3 of the compressor and the suction chamber 5 in the suction cover 3.
  • the delivery chamber 12a of the first compressor stage is delimited by the control disk 9a on the suction side, the control disk 10a on the pressure side and by the central body 11a.
  • the delivery chamber 12b of the second stage is limited by the control disk 9b on the suction side, the control disk 10b on the pressure side and by the center body 11b.
  • the pressure chamber 8 of the compressor is limited by the pressure cover 6 and the pressure port 7 of the compressor is arranged on the pressure chamber 8.
  • the pumped medium flows through the suction passage 14a of the first stage into the delivery chamber 12a, leaves this stage together with part of the auxiliary liquid through the pressure slot 17a and enters the chamber 21, which is the pressure chamber of the first and the suction chamber of the following Compressor stage is.
  • This space 21 is enclosed by the control disc 10a of the first stage, the control disc 9b of the second stage and the compressor housing part 22.
  • the medium flows together with a part of the Auxiliary liquid through the suction passage 14b in the delivery chamber 12b of the second stage, leaves it again through the pressure passage 17b in the control disk 10b and passes through the pressure chamber 8 into the pressure port 7 of the compressor.
  • the suction chamber 5 of the pump is delimited at the bottom as in FIG. 2 by a wall 15 which, at its lowest point, touches the geodetically lowest point of the suction slot 14a in the control disk 9a. 5, the wall 23 is arranged as a delimitation of the space 21, the wall touching the lowest point of the suction slot 14b in the control disk 9b of the second compressor stage. This provides a geodetically deep connection from the space 21 to the pumping space 12b of the subsequent stage.
  • the pressure chamber 8 is connected through the bore 19 to the delivery chamber 12b of the second compressor stage at the geodetically lowest point, the pressure chamber 8 being delimited at the bottom by the wall 18.
  • Bore 13a serves for central emptying of the first compressor stage to the outside, bore 13b for the second compressor stage.
  • the two bores which are indicated by dash-dotted lines in FIG. 4, can be connected by an additional line 27 which contains a shut-off element 28, so that the two bores 13a and 13b can be shut off from one another during compressor operation.
  • a combined shut-off device for example a three-way valve, is expediently provided for this purpose, which in a first position releases the connection of the bores 13a and 13b and also an opening to the outside and closes all of them in a second position.
  • the necessary operating fluid can be supplied to the compressor through a housing bore 24, via the space 26 arranged below the suction space 5 and a bore 25 in the control disk 9a.
  • the room 26 as well as the other rooms 27 and 28 located to the side of the compressor stage can also be used differently, for example for collecting dirt from the delivery rooms 12a and 12b.
  • the suction chamber 5 and the pressure chamber 8 are located in the same housing cover on one side of the delivery chamber of the compressor.
  • the figure shows a cross section through this housing cover looking towards the control disk.
  • the medium enters the suction chamber 5 through the suction nozzle 4 and passes through the suction passage 14 into the delivery chamber of the compressor.
  • the suction and pressure chamber are separated from one another by the wall 29.
  • the suction space is delimited at the bottom by the wall 15, which touches the geodetically lowest point of the suction passage 14.
  • connection bore 16 to the delivery chamber of the pump is provided in the geodetically lowest point of the suction chamber 5.
