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 in the preamble of Claim 1 specified features.
- Units of this type are increasingly used in compact heating systems today, especially installed in gas heaters or heating units. They include alongside the centrifugal pump unit usually other components, such as Air separator, safety valve, changeover valve or the like. They are considered Structural unit, d. H. designed as an installation and assembly unit, so that a simple and space-saving arrangement within the heating system is guaranteed. In addition, such a unit is easy to assemble and maintain because access to the otherwise narrow installation space is only available at a few central points must be guaranteed and the rest of the unit in the event of repair completely replaced and overhauled by the specialist at the factory or elsewhere and can be reused.
- Such a unit is known for example from EP 0 460 399 A2.
- the two heating circuits includes one for water heating and one for space heating, both through a common gas-heated primary heat exchanger be supplied with heat. Since the assembly for assembly in the lead of the Primary heat exchanger is provided, it has one suction port and two Pressure connection, which are connected to the two heating circuits. Furthermore points this known unit has an air separator on a backflow chamber is connected through which the return lines of the heating circuits the unit is guided. In addition, there is a flap between the Pump outlet and the two pressure ports provided depending on the Direction of rotation of the impeller is automatically controlled depending on the control to apply one or the other heating circuit.
- the present invention is based on the object to design a generic unit constructively so that the aforementioned Requirements met, but at least compared to a significant improvement the state of the art is achieved.
- connection housing with a central Provide chamber in which the suction mouth of the pump opens, in which the Switching element is arranged and in the two acted upon by the switching element Intake ports open, with an air separator in the upper area of the chamber is provided or connected.
- This arrangement requires a comparative one large central chamber that connects directly to the pump housing and in addition to connection functions, the switchover function and the ventilation function includes. Since the chamber has the two suction nozzles and the one acting on them Switching element contains, there is no separate piping between Switching element and pump required, as is the case with the prior art.
- the connection housing can be flanged directly to the pump housing be, the central chamber communicating with the suction mouth of the Pump is connected, which opens into it.
- the central chamber must be comparatively be tall.
- the aim is to reduce the size of the unit as small as possible hold, which is why it has so far been disregarded, a comparatively large Chamber, as required by the present invention to provide.
- the assembly according to the invention is special compact. This is because the chamber is essentially cylindrical Has shape and aligned with the pump housing substantially axially is arranged so that the connection housing, at least as far as it Area of the chamber concerned, essentially within the outer contour of the Pump housing is located and thus uses space that is not in practice anyway would be otherwise usable.
- pump housing in which only one is essentially tangential outgoing pressure port and otherwise one towards the connection housing Directed suction mouth is provided to form in one piece as an injection molded part. It is also possible in terms of manufacturing technology, pump housing and connection housing to be formed in one piece as an injection molded part. However, it is particularly advantageous Pump housing in two parts and the connection housing essentially in one piece train, because then a production of these components in the injection molding process without lost cores and with simple tools is possible, which reduces the manufacturing costs, significantly reduced in particular for mass articles of this type can be. In order to achieve high efficiency despite the simple design to achieve, it is advisable to use a comparatively large rotor insert into the pump housing.
- connection housing inexpensively without lost cores
- the connection housing which are located in the chamber
- This separate manufacture of the internal parts of the connecting piece also has the advantage that the sealing surfaces located in the chamber this nozzle, which are acted upon by the switching element, before the fixed connection separately processed, coated or at least with the connection housing can be targeted.
