Definitions
- the invention relates to a from a centrifugal pump and a driving this Motor existing submersible pump unit, the centrifugal pump and the Motor enclosing housing an outlet connectable to a delivery line has.
- a double jacket cooling for a pump unit is, among other things, through the FR-A-2 199 356 known. It is not a submersible pump unit; the basic structure of a double jacket can be very good there recognize well. Above all, it can be seen that the structure common up to now is one Provided double jacket, the integral part of the unit housing and of this could not be separated easily.
- submersible pump units have either been with or without Double jacket cooling performed. This means that when you order a Submersible pump must be decided whether the unit with a equipped such double jacket cooling and thus be more versatile should, or whether the cheaper version without double jacket cooling for the expected applications will be sufficient. A subsequent change is not possible with it. So should it turn out later that a Double jacket cooling would be necessary, the operator of a unit is without such additional cooling forced another submersible pump unit to purchase. The manufacturer of submersible pump units, however, must Manufacture units with and without double jacket cooling in parallel and keep them in stock.
- the invention is based, so aggregates of the type mentioned to make it easy to convert from one to the other other form of cooling becomes possible.
- Cooling jacket through which the medium delivered by the centrifugal pump to one instead of the outlet on the housing to be connected to the delivery line arrives, the housing being provided with outer surfaces on which inner surfaces of the cooling jacket are brought to the system, and with the sealant between Seal the existing gaps in the housing and the cooling jacket.
- the submersible pump assembly according to the invention is based on a basic version simple jacket cooling, which can be done at any time by an easy to carry out Change, for example by putting a cooling jacket over one, can be converted with double jacket cooling. If necessary, the Cooling jacket still with a detachable connection, for example by screws attached to the housing enclosing the centrifugal pump and the motor.
- the housing enclosing the centrifugal pump and the motor of the basic version in an advantageous embodiment of the invention provided with an outlet opening in the case of an operation without a cooling jacket, one with a delivery line connecting connecting piece.
- cooling jacket is to be manufactured as a separate part opens the Possibility of its material, shape or color to predetermined conditions or to adapt to customer requirements.
- Fig. 1 The basic version shown in Fig. 1 consists of a centrifugal pump, a these driving motor (both are not shown as such) and one both enclosing housing 1, part 2 of the housing 1, the centrifugal pump and part 3 encloses the motor.
- the housing 1 consists of several parts that are only hinted at here. For the invention, the number of Individual parts and the type of connection between them are irrelevant.
- the submersible pump unit according to the invention is shown in FIG. 1 Version with simple jacket cooling is used, so at the outlet opening 4 of the housing 1 a nozzle 5 attached to the connection of the unit with a - not shown - conveyor line.
- the nozzle can remain in place or, if it is detachable, can also be removed.
- FIG. 2 shows an embodiment upgraded to double jacket cooling. This has come about by putting a cooling jacket 6 on.
- the cooling jacket 6 has inner surfaces that correspond to corresponding outer surfaces on parts 2 and 3 of the housing 1 can be pushed. Through several screw connections 7, the cooling jacket 6 is attached to the housing 1. With O-rings 8 and 9 is that between the housing 1 and the cooling jacket 6 Gap sealed, so that the medium pumped by the centrifugal pump the unit leaves only via a connector 10 provided on the cooling jacket 6.
