Definitions
- the invention relates to a from a centrifugal pump and a driving this Motor existing submersible pump unit enclosed by a housing.
- Such units are usually operated submerged, so that the cooling of your engine by the liquid surrounding the unit he follows.
- the unit so far immersed in the fluid during a longer operating phase remains that the engine would be essentially cooled by the ambient air. There but this is usually not sufficient, you can see a constant in such cases Liquid cooling, which is achieved in that the engine by an additional Sheath is enclosed, in which the pumped by the centrifugal pump Liquid is led to the outlet of the unit.
- submersible pump units have either been with or without one Double jacket cooling performed. This means that when ordering a submersible pump must decide whether the unit with equipped with such a double jacket cooling and thus more versatile should be, or whether the cheaper version without double jacket cooling for expected use cases 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 one Additional cooling forced to purchase another submersible pump unit. The manufacturer of submersible pump units, however, must have units with and Manufacture in parallel without double jacket cooling and keep in stock.
- the invention is based, so aggregates of the type mentioned the task to make it easy to convert from one to the other other form of cooling becomes possible.
- the submersible pump assembly according to the invention is based on a basic version with simple jacket cooling, which can be changed at any time by an easy change, for example by slipping a cooling jacket into one with Double jacket cooling can be converted. 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 is provided in an expedient embodiment of the invention with an outlet opening, which is only used with a conveyor line when used without a cooling jacket connector to be connected.
- cooling jacket is to be manufactured as a separate part opens the Possibility of its material, shape or color to specified 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, the part 2 of the housing 1, the centrifugal pump and part 3 encloses the motor.
- the housing 1 consists of several parts are only hinted at here. For the invention, the number of Individual parts and the type of connection between them are irrelevant.
- 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, 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.
