Definitions

  • the invention relates to a structural unit for a compact heating system, in particular for a gas boiler with two heating circuits according to the features specified in the preamble of claim 1.
  • Such a unit is for example off DE 690 04 616 T2 known.
  • Building units of this type are nowadays increasingly being installed in compact heating systems, in particular in gas water heaters or heating units. They include in addition to the centrifugal pump unit usually other components, such as air separator, safety valve, changeover valve or the like. They are designed as a unit, ie as a mounting and mounting unit, so that a simple and space-saving arrangement is ensured within the heating system.
  • such a unit is easy to assemble and maintain, since accessibility to the otherwise tight installation space must be ensured only in a few central locations and otherwise completely replaced in the case of repair and factory or elsewhere overhauled by the specialist and reuse can be supplied.
  • a similar unit is for example off EP 0 460 399 A2 known.
  • the unit described therein is intended for a gas boiler, which includes two heating circuits, one for the hot water and one for space heating, both of which are supplied by a common gas-heated primary heat exchanger with heat. Since the assembly is provided for mounting in the flow of the primary heat exchanger, it has a suction nozzle and two Discharge nozzles connected to the two heating circuits. Furthermore, this known unit on an air separator, which is connected to a return flow through which the return lines of the heating circuits are guided by the unit. In addition, a switching flap between the pump outlet and the two pressure ports is provided, which is automatically controlled depending on the direction of rotation of the impeller to pressurize depending on the control one or the other heating circuit.
  • EP 0 460 399 A2 known unit has proven itself in principle. However, it is a constant endeavor to further improve such a structural unit, in particular to simplify its manufacture, to increase its compactness and to duplicate its range of use. So it is in particular a desire to combine in the unit further functions, especially on the unit as all possible piping centrally set. Another problem is that the arrangement of the connections within the heating system are not standardized, so that for each type, ie for each manufacturer to manufacture a separate unit, which significantly increases the manufacturing and storage costs.
  • the present invention seeks to design a generic unit constructively so that the aforementioned requirements met, but at least a significant improvement over the prior art is achieved.
  • the terminal housing with a central chamber in which the suction mouth of the pump opens, in which the switching element is arranged and acted upon in the two by the switching member Suction open, with an air separator is provided or connected in the upper part of the chamber.
  • This arrangement requires a comparatively large central chamber, which connects directly to the pump housing and in addition to connection functions also includes the switching function and the venting function. Since the chamber includes the two suction nozzle and this acting switching member, no separate piping between the switching device and the pump is required, as is the case in the prior art.
  • the terminal housing can be flanged directly to the pump housing, wherein the central chamber is communicatively connected to the suction port of the pump, which opens into it.
  • the central chamber must be made comparatively large.
  • the assembly according to the invention is particularly compact. This is because the chamber has a substantially cylindrical shape and is aligned with the pump housing substantially coaxially thereto, so that the terminal housing, at least as far as the area of the chamber is substantially within the outer contour of the pump housing and thus uses space which would not otherwise be usable in practice anyway.
  • the pump housing in which only a substantially tangentially outgoing pressure port and the rest is provided to the terminal housing directed towards the suction mouth, integrally form as an injection molded part. It is also technically possible, pump housing and terminal housing in one piece as an injection molded part. It is particularly advantageous, the pump housing in two parts and form the terminal housing substantially in one piece, since then a production of these components by injection molding without lost cores and with simple tools is possible, whereby the manufacturing cost, especially for mass products of this type can be significantly reduced. In order to achieve a high efficiency despite the structurally simple structure, it is expedient to use a comparatively large impeller in the pump housing.
  • the switching device consists of a sealing element located on a lever, which passes tightly through the chamber wall and outside of the chamber by an actuator, an electric motor, can be acted upon.
  • the sealing body of the switching element can either close the opening into the chamber end of the one or the other suction nozzle. That's why it is structurally particularly favorable to arrange the suction nozzle opposite and transverse to the impeller of the pump within the terminal housing.
  • the terminal housing on its side facing away from the pump housing with a further component, namely an adapter housing.
  • This adapter housing can serve, for example, the assembly formed by the motor housing, pump housing and terminal housing to heating systems of different types, d. H. adapt to different manufacturers, so that only the adapter housing manufacturer-specific form, but not the entire unit.
  • the suction nozzles and possibly further auxiliary nozzles are led out on the end face directed towards the adapter housing, so that additional piping in this area can be dispensed with.
  • the adapter housing not only serves to adapt to the manufacturer-specific connections of the heating system, but can also be used for fastening the entire structural unit within the heating system.
  • appropriate fastening means are provided on the adapter housing.
  • additional components or connections for example dirt collectors, pressure gauges, bypass connections or the like, on the adapter housing. It is understood that these connections may possibly also be provided on the connection housing, if this should be expedient.
  • the terminal housing can also form a mounting base for other located within the heating system components, in particular for the usually located there plate heat exchanger, which the heat transfer between the heating circuit and hot water circuit guaranteed. The arrangement of this heat exchanger near the unit is particularly useful, since this heat exchanger has at least four pipe connections, which are to be cased and thus at least partially formed by the adapter housing.
  • FIGS. 1 to 7 The basis of the FIGS. 1 to 7 The assembly shown is essentially formed by a motor housing 1, a pump housing 2, a terminal housing 3 and an adapter housing 4 with the individual components located therein or thereon.
  • an electric motor is arranged in a conventional manner, on the motor housing 1, the usual terminal box is still flanged.
  • the electric motor drives a gyro wheel which runs inside the pump housing 2.
  • the pump housing 2 is releasably secured to the motor housing 1, it has a substantially cylindrical pump chamber, connected to the approximately tangential line, which opens into a laterally projecting on the pump housing 2 discharge nozzle 5.
  • Substantially aligned with the pump chamber is separated by the plate 6, but fluidly connected through the opening 7, a substantially cylindrical chamber 8 in the connection housing 3 on.
  • the terminal housing 3 is flanged to the pump housing 2 and fixed by screw, tight and releasably connected to the pump and thus the motor housing 2, 1.
  • the structure of the terminal housing 3 is based on FIGS. 7 seen.
  • the chamber 8, which is open towards the pump housing 2, is closed by an end wall 9 on the side facing the adapter housing 4.
  • three through openings are provided, two of which are based on the impeller axis approximately at the same level and are designed as suction nozzle 10 and 11, wherein the suction nozzle 10 for the heating system supplying the space heating and the suction nozzle 11 for the hot water heating circuit is provided.
  • the third intermediate opening is formed as a connecting piece 12 and serves to connect a safety valve.
  • Fig. 7a The located within the chamber 8 parts of the suction nozzle 10 and 11 are formed as a pipe bend 13, as in Fig. 7a are clearly visible in a non-installed position. So that the terminal housing 3 can be injected without lost cores, these elbows 13 are used after the actual shaping of the housing 3 and connected by welding to the rest of the housing 3, in particular the there inwardly projecting nozzle. In the Fig. 7a Forward facing sides of the pipe bend 13 are closed. The visible there annular projections are used exclusively for handling during assembly.
  • a lever 15 is sealingly carried out, at its end located in the chamber 8 a sealing body 16 is located, which closes depending on the position of the two pipe bend 13 and the other releases or vice versa, so that the chamber 18 either with the Suction nozzle 10 or fluidly connected to the suction nozzle 11.
  • the lever 15, which is pivotally mounted in the region of the aperture, is acted upon at its free end by a spindle drive, which is attached by means of a laterally on the housing part 14 Electric motor 17 is driven. About the spindle drive, the pivoting of the lever 15 and thus the control of the switching element formed thereby takes place.
  • the cylindrical part of the terminal housing 3 has on its upper side a pipe section 18, which projects into the chamber 8 a piece, having a closed bottom and communicating via a lateral opening with the chamber 8 is connected.
  • the pipe section is open and provided for the use of an unillustrated and well-known in the heating technology Enlplexers (air separator).
  • the adapter housing 4 connects, which is relatively flat and the block formed from the motor housing 1, pump housing 2 and terminal housing 3 laterally and downwardly clearly surmounted.
  • the adapter housing is connected via laterally protruding on the terminal housing 3 connecting sleeves 19 to the terminal housing 3 by screws.
  • Fig. 1 and 2 it can be seen that the connecting pieces 10 to 12 of the terminal housing 3 are tightly incorporated into corresponding connection openings of the adapter housing 4, so that the connection of the unit, once apart from the connection of the pressure port 5, takes place exclusively via the adapter housing 4. Since the component arrangement within a heating boiler in almost all manufacturers is basically the same, only distances between the terminals and dimensions differ, by varying only the adapter housing 4, the unit manufacturer can be adjusted without having to vary these other parts 1, 2 and 3.
  • a dirt separator 20 is provided and an external safety valve 21. Furthermore, the adapter housing 4 downwardly projecting pin 22, with which the adapter housing 4 and thus the entire assembly within the heating system on a in Fig. 2 shown cover plate 23 can be fastened. Furthermore, the Adapter housing laterally on a mounting base 24 for a plate heat exchanger 25.
  • the function of the above-described unit results in particular from the FIGS. 1 to 3 ,
  • the pressure port 5 is connected via a line 26 to the boiler (primary heat exchanger) 27 of the heating system.
  • the boiler 27 feeds either the heating circuit 28 intended for space heating or the heating circuit 29 intended for hot water preparation, which includes the plate heat exchanger 25 whose service water connections are marked 30 and 31.
  • a bypass line 32 is provided between the outlet of the boiler 27 and the suction side of the pump, which opens within the adapter housing 4 in a spring-loaded valve.
  • the above-described unit is in Fig. 3 symbolized by the rectangle labeled 33, wherein each point in this diagram represents a line connection. This graph in connection with Fig.
  • FIG. 2 shows quite clearly how far it has been possible by the assembly according to the invention to integrate almost all line connections in the unit or in their immediate vicinity.
  • return line 24 opens directly.
  • the return line 35 of the heating circuit 28 opens below the terminal housing 3 at the in Fig. 2 invisible side of the adapter housing 4 (see Fig. 1 ).
  • a terminal 36 for connection to a pressure equalization tank 37 and possibly another connection for a pressure gauge 38 is provided.
  • the unit according to Fig. 8 differs from the above-described in that it is not provided for connection to the adapter housing 4.
  • the inner parts of the suction nozzle 10a and 11a are therefore designed as straight pipe sections, but have the same function within the chamber 8 as the pipe bend 13.
  • the suction nozzle 10a and 11a are arranged laterally opposite to the transverse axis of the wheel, lie further connecting piece 12a etc. sämtlichst in a plane transverse to the impeller axis, with the exception of the pressure port fifth
