Definitions
- the invention relates to a centrifugal pump with a suction and a pressure port, each on a connecting flange a pipe can be connected.
- centrifugal pumps are known in a variety of forms, e.g. US-A-5,480,289 and are used, for example, in heating circuits.
- to Installation of the pump has cut out a piece of the pipeline, into which the pump with its nozzle in line is used.
- the distance between the pipe flanges corresponds to the standardized distance of the connecting piece, so that the pump can be replaced at will.
- This is on Pump connector the corresponding counter flange for Pipe flange molded, the type and size of the Pipe flanges by the type and size of the flanges Pump nozzle is fixed. Because the relevant standards are not internationally recognized, it is necessary for other countries to provide different pump housings. An easy one Exchange is not possible.
- the object of the present invention is therefore a pump to create that with easy handling and construction the possibility of integration in different dimensions Pipe socket offers.
- a particular advantage of the pump is that it is characterized by the interchangeable adapter easily and conveniently to any Circuits can be adjusted. So it doesn't need for other systems the whole pump housing can be dimensioned differently, it is only necessary to provide an appropriate adapter that is inserted into the recess formed on the pump and on the one hand against admission and on the other hand against Seals the connection flange on the pipe system. Because the adapter over protrudes beyond the edge of the recording, it alone forms that Counterpart to the pipe flange.
- the adapter has the Possibility of integrating other hydraulic components offers in the fluid circuit. So one can with the Pump inventive hydraulic system simple and inexpensive way modular by others Components are added without changes to the connection options given by standard dimensions Pipelines must be made.
- the invention Pump especially centrifugal pump, serves as a module carrier and inevitably forms with one or both Trim a receptacle for the one with the desired component equipped adapter.
- the nozzle can be designed in this way be that several components in sandwich-like stacking be put together.
- the adapter or the bracket forms the counterpart to the connecting flange according to the invention the pipeline.
- the bracket during installation offers some play in the axial direction with the eventual Pipeline tolerances can be compensated.
- the pump according to the invention can be handled as the previously known pumps. To do this, the adapter or Bracket against falling out by an externally accessible Screw secured. This screw forms at the same time a transport lock, so that the pump in the with the required adapter assembled state can.
- the design of the pump according to the invention can be based on different types. It is essential that one of the Stub is formed as a part of the connector on which the adapter can be attached in the axial direction. there seals the bracket directly or indirectly against that of the Socket formed receptacle and against the connecting flange. It is particularly useful to use one of the pump nozzles Form cup-shaped receptacle into which an annular Adapter or an annular bracket for the hydraulic Component can be inserted. The cup-shaped receptacle forms thereby a socket into which the adapter or the holder is insertable.
- a non-return valve is used in the pressure side bracket.
- This check valve serves the liquid column in the system as a gravity brake if the pump is not running.
- On such check valve is in contrast to known, in Heating water circuits integrated valves simply use and thus inexpensive to assemble and Maintenance.
- the Pressure port in the flow direction in front of the in the holder check valve used an additional shut-off valve arranged.
- the shut-off valve is advantageously so trained that it as well as the check valve as optional module in a corresponding recording of the Pressure port are used.
- the shut-off valve is in an advantageous embodiment by simple mechanical means can be operated from the outside.
- Another particular advantage of the invention is that it is now possible to modular in the pump housing use hydraulic components without the overall length of the Change pump.
- the seal remains with the Connection flanges of the pipeline guaranteed.
- Figure 1 is a pump in the form of a centrifugal motor pump 1 shown.
- the pump housing 2 forms a pump chamber 3, in which an impeller, not shown, coaxial with the axis 4 is mounted on a shaft.
- the wave is from one Electric motor 32 operated, which together with the shaft to the Flanged housing.
- the pump chamber 3 points to the a side facing away from the electric motor 32 has a coaxial inlet on, which is connected to the suction nozzle 6. Further points the pump chamber 3 has an outlet 7 which leads to the pressure port 8 leads ( Figure 2).
- Suction nozzle 6 and pressure nozzle 8 lie on a common one Axis (in-line) and are not on the connecting flange 13 shown pipeline connected.
- a shut-off valve with a rotatable flap 10 attached.
- Adjusting bolt 11 fastened, which is rotatable in the pump housing 2 are stored and by means of a housing 2 outstanding head 12 in the form of a hexagon from the outside can be moved.
- the two flaps are each of an annular shape Sealing sleeve 19 surrounded by plastic, which is coaxial in the The end of the nozzle lies in and can be pressed in from the outside.
- an annular metal insert 23 one that has a central area of the cylindrical Cuff outer jacket forms and a clearance fit to Has inside the socket.
- the annular metal insert 23 is thus on both ends and on the inside Flap 10 facing the plastic of the sealing sleeve 19 surround.
- the pressure port 8 is designed as a plug connection into which a Holder for an adapter used for hydraulic components 14 can be used.
- 8 is in the area of the pressure port a cup-shaped receptacle 15 on the pump housing 2 cast into which the bracket 14 with the hydraulic Component, in this case a check valve 16, is used.
- the adapter 14 projects beyond the outer edge 32 the recording.
- the check valve 16 is with its by a spring 17th against the valve seat acted valve flap 18 in one the annular housing 14 forming the valve housing Built in metal.
- the inserted annular holder 14 forms with its Connection flange 13 directed base 20 the right one Counterpart to the connecting flange 13.
- base 20 to seal against the connecting flange 13 is on the Base 20 a flat gasket 21 glued on.
- Sealing of the holder 14 with respect to the sealing collar 19 is this on the outer face with a molded Ring bead 25 provided on which the adapter 14 with the Base 22 rests sealingly.
- a sealing ring can be on the paragraph 31 of the receptacle 15 be inserted in a corresponding groove.
- the adapter or the holder 14 is axially in the receptacle 15 displaceable against paragraph 31 and in the radial direction held positively by the edge of the receptacle 15. in the unmounted state, the bracket 14 by a Edge of the receptacle 15 penetrating and into a blind hole 26th the wall 27 of the bracket 14 engaging screw 28 secured against falling out.
- the inside diameter of the Blind hole 26 is larger than the diameter of screw 28, to compensate for a certain tolerance.
- the Retaining rings 29 holes 30 in the same pitch as in the Connecting flange 13 introduced so that an attachment in the known type is possible by screws.
