Definitions
- the invention relates to a multi-flow liquid ring pump.
- nozzles are provided on the side plates arranged on the end face of the impeller housing, which protrude radially from the impeller housing and form the inlet and outlet openings and are connected to one another via corresponding connecting pipes.
- Each of these connecting pipes also has a suction and a pressure connection for the supply and discharge lines.
- This arrangement and design of the connecting pipes results in a large space requirement for the liquid ring pump.
- the connecting pipes must first be installed at the location of the liquid ring pump.
- connecting channels extending between its two end faces are formed in the impeller housing.
- the object of the invention is to develop a multi-flow liquid ring pump in such a way that the space requirement for the liquid ring pump is as small as possible while maintaining a housing shape that is favorable for production.
- a pure plug connection of the connecting tubes is achieved in that the inlet and outlet openings of the side shields are surrounded by a receiving edge and the connecting tubes lie with their two ends in a sealed manner on the receiving edge of the opposite openings.
- the sealing is expediently carried out by means of an elastically hardening liquid sealing compound.
- the suction and the pressure opening are provided on one of the side plates. It is again advantageous if the suction and pressure openings are provided on the end face of the side plate on the side facing away from the drive motor of the liquid ring pump.
- pipes serving the supply of operating fluid or the pressure equalization between the two pump halves of the liquid ring pump can be connected in the same way as the connecting pipes to corresponding connection openings in the side plates.
- connection openings are formed on the mutually facing sides of the side plates, so that the tubes for
- Impeller housing can be inserted parallel between the side shields.
- the invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing. It shows:
- 1 shows a liquid ring pump in side view
- 2 shows a view of a side plate along the
- FIG. 3 shows an enlarged view of the connection point of a connecting pipe to the corresponding opening in a side plate.
- the liquid ring pump can be coupled to a drive motor with the one shaft end 6 projecting from the bearing in question.
- the multi-flow of the liquid ring pump is achieved in that the impeller housing 1 has two impellers separated from one another by an intermediate wall of the impeller or an impeller divided into two impeller halves by a center wall formed on the impeller and extending radially to the circumference of the impeller is provided.
- the two side plates 2 and 3 On the sides facing each other, the two side plates 2 and 3 have inlet and outlet openings 7 and 8. The two respectively opposite openings 7 and 8 of the side shields 2 and 3 are each connected to one another via a straight connecting tube 9 running parallel to the impeller housing 1. Between the two side plates 2 and 3 further extends a tube 10 which connects the corresponding connection openings 11 of the side plates 2 and 3 to one another. Operating liquid can be conveyed from one pump half to the other via this pipe 10, or a pressure equalization between the two pump halves can be brought about.
- Such a tube 10 can be provided on both long sides of the impeller housing 1, so that both the delivery of operating fluid and pressure equalization are possible.
- a supply opening 12 only needs to be provided on a side plate 3 because of the arrangement of the tube 10.
- a suction opening and a pressure opening 13 and 14 are provided on the end face thereof.
- an annular connecting edge 15 is formed on the side plate 3, with which the side plate 3 bears against the impeller housing 1 with the interposition of a control disk.
- the side shields 2 and 3 are rectangular. This results in the impeller housing 1 having radially projecting corners 16 of the side plates 2 and 3. In these corners 16, the inlet and outlet openings 7 and 8 and the connection openings 11 are formed on the sides of the side plates 2 and 3 facing one another.
- the inlet and outlet openings 7 and 8 are surrounded by a receiving edge 17.
- the respective connecting tube 9 lies against this receiving edge 17, a seal 18 being interposed (FIG. 3).
- an insertion edge 19 is screwed onto the ends of the connecting tube 9.
- the seal 18 can consist of a liquid sealing compound which hardens elastically after being introduced into the gap existing between the connecting pipe 9 and the receiving edge 17.
- connecting pipes 9 extend between the corners 16 of the side plates 2 and 3, they lie within the contour of the liquid ring pump determined by the side plates 2 and 3. Since these connecting pipes 9 are already installed during the manufacture of the liquid ring pump, the subsequent installation of the liquid ring pump is made considerably easier. At the set-up, only the supply and discharge lines have to be connected to the suction opening 13 and the pressure opening 14 of the side plate 3.
- the gas to be pumped by the liquid ring pump is fed to the liquid ring pump via the feed line. Via the suction opening 13, the gas enters a suction chamber 20 formed on the side plate 3.
- the outlet opening 8 of this side plate 3 is connected to this suction chamber 20, so that the gas via this outlet opening 8, the connecting pipe 9 and the inlet opening 7 of the side plate 2 also reaches its suction chamber.
- the gas flows through corresponding inlet slots of the control disk into the compression chamber of the liquid ring pump. After the gas has been compressed, it is expelled into a pressure chamber 21 provided on the side plates 2 and 3.
- the gas compressed in one pump half reaches the pressure slots 21 of the control disc directly into the pressure chamber 21 of the side plate 3.
- the gas compressed in the other pump half flows through the pressure slots of the corresponding control disk into the pressure chamber of the side plate 2 and from there passes through the outlet opening 8 of the side plate 2, the connecting pipe 9 and the inlet opening 7 of the side plate 3 into its pressure chamber 21 opening pressure opening 14, the gas can flow into the discharge line connected to the pressure opening 14 and be conducted away from the pump.
