Definitions

  • the present invention relates to a system comprising a pump, in particular an electrically operated centrifugal pump, and an adapter for the Connection of the pump to a piping system, the adapter one for Suction mouth of the pump leading suction nozzle and a the pump medium has laxative discharge nozzle.
  • the invention also relates to a pump with "in-line" pressure and suction nozzle.
  • the object of the invention is therefore such a system or such To create the pump that is inexpensive and easy different connection conditions, such as those of the respective Pipe systems can be specified, can be adapted.
  • the essential advantages of the invention result from the exchangeable ones Fittings, which according to the pipe system User selected and attached to the adapter or the pump housing can be.
  • These small connectors give great flexibility of the system or the pump with regard to the adaptation to existing ones Conditions reached.
  • the fact that only the connectors and not that Whole pump housing needs to be replaced can be significant Cost savings and an even greater adaptability be guaranteed.
  • the connectors can be much cheaper manufacture as the complete housing.
  • the modular system created in this way can can be put together according to your needs.
  • the connectors can be used by the user from the manufacturer to the pump or offered for the adapter or supplied with the system Connectors are selected.
  • both the suction and the pressure nozzle of the adapter or the pump each have a flange
  • the Dimensions of this flange define a pump-side connection standard. All connectors available to the system are supplied with a appropriate counter flange to ensure the versatile attachment of the Allow fittings on the pump.
  • the connection standard is a simple replacement of the individual connection pieces guaranteed. Replacing the fittings and installing the pump can be carried out on site by a specialist or by a handyman.
  • the peculiarity of the defined connection standard offers the manufacturer the Possibility to monopolize the dimensions for themselves in order to offer competitors to prevent fitting connectors. It is therefore special Connection standard created a manufacturer-specific modular system that the Customers the relationship to a certain manufacturer and thus a special one There is certainty regarding the expected quality.
  • the pump Connectors which are formed by small pieces of pipe, on one side a corresponding counter flange fitting in the standard flange, so that a Plugging onto the pump is made possible.
  • a connector On the other side of the Pipe piece is a connector that is used to connect the Connection piece to the respective pipe system is suitable.
  • the Pipe pieces bent or straight. You can even use multiple strands branch. In total, all connectors can be a predetermined amount be removed, whereby the manufacturer will endeavor to the connectors to be offered in accordance with the various standardized pipe fittings.
  • the range of connectors can vary according to national connection standards set up so that one and the same system in different countries with are offered and sold according to different connectors can.
  • connecting pieces from metal, to be able to weld them to the pipe ends or to increase them To achieve pressure security. It is in lower pressure systems, however advantageous to adapters, pump housings or plastic connectors manufacture in order to save weight.
  • Standard flange on the adapter or on the pump housing is advantageous to Standard flange on the adapter or on the pump housing as a socket
  • the inner walls of which are aligned to a polygon.
  • a hexagon socket can be used as a polygon on the one hand offers high stability against a rotary movement and on the other hand the flow channel leaves an opening of sufficient size.
  • the Connector that has a corresponding insertable into the receptacle External polygon, in particular an external hexagon, can then in a corresponding plurality of positions rotated against each other plug in.
  • About the inside or outside polygon is the connector in radial direction and in the direction of rotation positively held on the adapter.
  • the axial support is advantageously ensured by the fact that in the scope of the Outside hexagon of the connector a groove is milled and that in the Standard flange a locking pin can be used, which after inserting the Connector is inserted into a hole and engages in the groove. Thereby is a secure hold and easy assembly of the connector.
  • the seal between the connector and the pump is made advantageously by a sealing ring, which in the bottom or the wall of the Recording is introduced.
  • FIG. 1 a so-called inline pump 1 is shown, the suction port 2 of which is coaxial with the pressure port 3 in a line.
  • the pump instructs Pump housing 4, in which the impeller, not shown, is rotatably mounted and is driven by a motor which is arranged in the motor housing 5.
  • the Electrical supply of the motor happens via the terminal box 6, which is on the motor housing 5 is attached.
  • the Suction 2 and the pressure nozzle 3 designed as a flange (standard flange) on the a connector 7 shown in Figure 2 is replaceable.
  • This Connector 7 is specified from a quantity by the manufacturer of the pump Selectable connectors.
  • the inline flanges of the suction and the Pressure port 2 and 3 on the same connection standard. It is about a cup-shaped receptacle 8, into which an internal hexagon 9 is introduced (see Detailed drawing, Figure 1, bottom right).
  • the pot-shaped Recognize recording that has a bore 10 tangentially, in which a shown locking pin can be inserted. This locking pin engages its circumference in a corresponding groove 15 on the connector 7. The depth the intervention is shown by the broken line 11.
  • a connector 7 is shown in two perspectives, as in the Recording 8 can be used.
  • the counter flange is designed as an external hexagon, which in the Hexagon socket 9 is insertable.
  • the connector 7 also assigns one a fitting 13, not shown, for a pipe fitting, the one with the corresponding counterpart, which is located at the end of the pipe, under Inclusion of a seal can be screwed on.
  • the connector points between the counter flange 12 and the connecting piece 13 a curved Pipe section 14, which can be straight in the case of other connectors or can also branch into several connecting pieces.
  • the FIG. 2 clearly shows a groove 15 which is in the external hexagon 12 is introduced and the with the inserted external hexagon Engagement of the locking pin allows. The locking pin is therefore in the groove 15 and prevents the connector from slipping out.
