Definitions

  • the invention relates to a centrifugal pump with a canned motor and a single impeller which is arranged in a pump housing which has an inlet and outlet.
  • centrifugal pumps has molded, protruding inlet and outlet connections which are fastened to pipes or devices by means of pipe fittings. Such an installation requires a considerable amount of space and the parts required for this increase the overall weight. Manufacturing and assembly costs are also high and different connection parts are required for each pump type or pump size.
  • the object of the invention is to improve a centrifugal pump in such a way that it is easy to assemble with the smallest space requirement.
  • This object is achieved in that the opening forming the outer end of the inlet is coaxial with the impeller axis and in the plane of the side wall of the pump housing, and that the pump housing with this flat side wall can be attached directly to the wall of a consumer or connecting device.
  • Such a pump can be attached with its flat side wall directly to the flat side wall of a device without any intermediate parts. It is therefore sufficient that the device to which a pump is to be connected has a smooth surface with two openings in this surface in order to mount a pump directly with the least amount of assembly work. Connection parts and intermediate parts are not required, so that considerable space and weight are saved. There is no need for pipe fittings. Very compact heaters and heating units can be created. On the side facing the consumption or connection device, the pump lacks a pressure wall, so that weight and space are saved. Manufacturing, assembly and changes are also simplified.
  • Those who need a pump for a device need only ensure that regardless of the desired pump size and pump type, the same two openings of the same size are always present on the outer wall or on an intermediate wall with the same distance, in order then to give the pump the desired power order and fasten.
  • a particularly simple assembly is made possible when the opening forming the outer end of the outlet is axially parallel to the impeller axis and in the plane of the side wall of the pump housing.
  • the side wall of the pump housing can be attached to the wall of the consumption or connection device directly or by means of sealing means.
  • a particularly small construction is achieved when the side wall of the pump housing having the inlet opening is perpendicular to the axis of the impeller. It is particularly advantageous if the side wall of the pump housing which has the inlet opening is circular and coaxial with the rotor.
  • the pump housing have an inner insert which forms a spirally widening outlet channel and which is surrounded on the outside by an outer housing which is fastened to the drive motor and which lies with its side edges against the wall of the consumption device.
  • This not only leads to a particularly pressure-tight encapsulation of the pump, but also to an interchangeability of the inner insert, which can be adapted to the most varied of conditions.
  • the inner insert forms the connection surface to the consumption or connection device. Any position of the pump in the installed state can be reached if the inner insert in the outer housing is rotatably adjustable.
  • the side wall of the pump housing or the outer housing has at least one flange on the outer edge with which the side wall can be fastened to the wall of the consumption device. Screws inserted in the bores of the flanges result in simple and secure attachment of the pump to the consumption device.
  • a quick and simple assembly and disassembly is made possible in that the pump, in particular the (outer) housing, is fastened to the consumption or connection device by means of a bayonet lock. Manufacturing and assembly are facilitated if the motor housing and pump housing, in particular the pump outer housing, are made in one piece. Alternatively or additionally, the can of the motor and the pump housing, in particular the pump outer housing, can be made in one piece for this purpose.
  • a part is attached between the pump and the consumption device, which forms a coaxial annular chamber around a pipe aligned with the pump inlet, which can be connected to the pump outlet and the inlet of the consumption device.
  • the pump can be attached in any rotational position regardless of the position of the consumer inlet.
  • the size of the consumer inlet can vary and there can be multiple consumer inlets.
  • centrifugal pump for a use of the centrifugal pump according to the invention it is advantageously proposed that it be on the flat outer or intermediate wall of a heating duct, heater, liquid storage container, heat exchanger, pump housing, pipe connection, hot water device, breather, dirt trap, differential pressure regulator, measuring transducer, pre-swirl shut-off device, mixer, flow regulator or a gravity brake can be fastened, the outer or intermediate wall having two openings which correspond in distance and / or diameter to those of the side wall of the pump housing.
  • the canned pump is used as a hot water pump, especially in heating systems.
  • the pump 1 has a pump housing 2, 11, in particular made of plastic or metal, in which an impeller 3 is rotatably arranged and in which a tubular inlet 4 is formed coaxially to the impeller, through which the impeller is directly flown.
  • a spirally widening outlet channel 5 Around the impeller there is a spirally widening outlet channel 5.
  • the housing 2 is in the form of a circular disk, the height H of the cylindrical outer wall being substantially less than the diameter of the circular flat pump side wall 6, which is at right angles and coaxial to the axis of the impeller 3.
  • the inlet 4 opens with an inlet opening 7 and the outlet channel 5 with an outlet opening 8.
  • the openings 7 and 8 are in the plane of the side wall 6.
  • a canned electric motor 9 coaxially attached to the impeller 3, which lies with its drive shaft 10 in the impeller 3.
  • the pump housing 2 consists of an inner insert 2 which closely surrounds the impeller 3 and forms the spirally widening outlet channel 5 around the impeller, and an outer housing 11 surrounding the insert 2, which is fastened to the electric motor 9 and carries seals 13, which are in the plane of the side wall 6.
  • the insert 2 thus forms the flat interface to the consumption or connection devices.
  • the outer housing 11 which acts as a pressure vessel, forms flanges 12 parallel to the side wall 6, which have bores 14 in order to be able to accommodate screws. With these screws, not shown, the outer housing 11 and thus the entire pump can be attached to consumption devices.
  • Impellers 3 and inserts 2 of different powers can be inserted into this outer housing 11.
  • the impeller 3 can be replaced by a differently shaped impeller, but the spiral channel 5 surrounding the impeller and the inlet can be adapted to the respective impeller and the desired power as well as to the respective speed range.
  • the inlet and outlet openings 7, 8 in use 2a can be adapted to the conditions of the consumption or connection devices in terms of their distance from one another and also in their arrangement in the flat side wall 6. It is sufficient to change the insert 2a in order to meet the requirements.
  • the outlet on the circumference of the housing can be arranged radially or tangentially. It is also important that the side wall 6 of the pump housing 2 or the outer housing 11 has at least one flange 12 on the outer edge, with which the side wall can be fastened to the wall of the consumption device.
  • the inner insert 2 can be made smaller than shown in Figure 1. It may be sufficient if it only forms the inlet opening 7 and the diffuser for the impeller 3.
  • the insert 2 can also consist of several parts. It is particularly easy to manufacture if it is made of plastic. In particular, this will it is possible and economically justifiable to include different shaped inserts for the pump so that the user can change the pump performance before installation.
  • the pump in particular the (outer) housing
  • the consumption or connection device by means of a bayonet lock.
  • Motor housing and pump housing, in particular pump outer housing 11, are made in one piece.
  • the can of the motor and the pump housing, in particular the pump outer housing 11, are made in one piece.
  • FIG. 7 shows an embodiment in which a part 30 is fastened between the pump and the consumption device, which forms a coaxial annular chamber 31 around a pipe 32 that is aligned with the pump inlet and can be connected to the pump outlet and the inlet of the consumption device.
  • Consumption devices are understood to mean all the devices, parts and devices to which a pump is usually attached. These can include the following: a heating boiler, heater, hot water device, liquid storage container, heat exchanger, pump housing, pipe connection, breather, dirt trap, differential pressure regulator, sensor, pre-swirl regulator, flow divider, mixer, a shut-off device or a gravity brake.
  • a venting device 15 is shown, on the left flat side wall of the pump 1 can be screwed.
  • This ventilation device with ventilation chamber 16 and. Grid 17 and upper vent 18 can be screwed with the side opposite the pump to a further device 19 (FIG. 2), which can be a heater, boiler, boiler or other consumption device.
  • the ventilation device 15 forms an intermediate part between the device 19 and the pump 1, which is flowed through by the two streams of water.
  • the pump sucks water through the ventilation chamber 16 to the inlet opening 7 and then presses this water back through the opening 8 and the flow nozzle 21 to the channel 22 of the device 19.
  • Opening 6, flow connector 21 and channel 22 are coaxial with each other.
  • the inlet opening 7 and the channel 20 are coaxial to one another and the ventilation chamber 16 is at the same height.
  • the pump can be attached to a sheet metal wall 23, as shown in Fig. 2, which sheet metal wall is part of any device. Instead, the pump can also be attached to the outer wall 24 of a cast iron boiler member 25 (Fig. 5). In Fig. 6, a pipe connection part 26 is also shown, to which the pump can be fastened, so that this turns the pump 1 into a conventional pump with radial or tangential pipe connections. Such a flat connection part can also be attached laterally to the pump in order to create a radial or tangential outlet. Furthermore, a flat connecting part can be fastened, which forms a concavely curved outer surface on the side surface facing away from the pump for consumers who have a correspondingly convexly curved connecting surface.
  • the distance between the openings 27, 28, on which the openings 7, 8 of the pump come to rest are always at the same distance from one another and of the same diameter corresponding to the openings 7, 8 a wide variety of pumps can be attached to the devices as long as the distance between the openings 7, 8 and their diameter is the same. Pumps of different capacities can thus be attached without having to change the distance between the channels or openings 27, 28 on the consumption devices. However, if other distances between the openings 7, 8 from one another are required, then the inner insert 2a can be exchanged for an insert with openings whose spacing corresponds to the desired one.
  • all disk-shaped devices 15 or parts 30 fastened between the pump and the consumption or connecting device 15, 19, 25, 26 are fold-symmetrical about an axis which intersects the pump rotation axis and is perpendicular to it.
  • the pump outlet or the pressure port can protrude radially or tangentially from the housing.
