Definitions
- the invention is based on the object of improving a pump of the type mentioned in the preamble of claim 1 with regard to the cooling of the seal housing.
- the solution according to the invention consists in the features of claim 1 and preferably the features of the subclaims.
- the invention is characterized in that the conveying direction of the fan wheel runs from the pump to the bearing housing and that the air flow cross sections formed by the mudguard are arranged in the axial region of the seal housing and / or on the pump side thereof in such a way that the air has a radial directional component on the seal housing and / or the connection between the sealing housing and the pump housing meets and is deflected on the sealing housing towards the fan wheel.
- the thermal insulation device can simply be formed by a sheet metal disk, which is placed in front of the pump housing and encloses a heat-insulating air space with the latter.
- the seal housing can be expedient for the seal housing to be connected to the pump housing via a tube of small cross-section (DE-A 26 30 513) in order to reduce the heat flow to the seal housing. Furthermore, for the same reason, it may be expedient to provide the seal housing with circumferential grooves which at the same time enlarge the heat-emitting surface of the seal housing.
- the bearing housing in such a way that it shields the motor from the fan.
- the housing of the pump 1 comprises a cover 2, which forms a bearing 3 for the shaft 4 and is tightly connected to the rest of the pump housing in the region of an axially advanced collar 5.
- the connection is brought about by screw bolts 6 which engage a ring 7 which is appropriately attached to the collar 5.
- the housing hub 8 containing the bearing 3 is also opposite the housing wall connecting it to the collar 5 axially extended, and even further than the collar 5.
- the space 9 in between is closed by a sheet metal plate 10, which acts in conjunction with the air space 9 as a thermal insulation device, because it releases the uninhibited heat from the cover 5 the ambient air prevents.
- a flange 11 is attached to the housing hub 8 and carries the seal housing via a tube 12 of small cross-section, which is composed of a part 13 on the pump side and a part 14 remote from the pump.
- the part 13 of the seal housing close to the pump contains circumferential grooves 15 which narrow the housing cross section which is available for the heat conduction from the pump to the seal 16.
- the ring 7 connected to the pump housing bears a number (for example two to four) of longitudinal struts 17 which connect it to the flange 18 of the seal housing 19.
- the parts 7, 17 and 18 form a lantern which connects the bearing housing 19 which is integrally connected to the pump housing.
- a plurality of support projections 26 extend radially inward from the longitudinal struts 17 of the lantern to the sealing housing 13, 14 for the purpose of centering the same.
- a roller bearing 20 for the shaft 4 is contained, which is designed here as a coupling bush 21 for receiving the stub shaft of a drive motor, which can be attached to the flange 18.
- a protective plate 23 which encloses the one enclosed by the lantern 7, 17, 18 Encloses area and extends from the ring 7 to the flange 18. It contains supply and exhaust air cross sections in the form of holes 24, 25. The supply and exhaust air cross sections could also be designed differently.
- the air inlet openings 24 are at an axial distance from the fan 22. Since the air enters through them with a mainly radial flow direction, it is directed onto the seal housing 13, 14 and onto the pipe section 12 before it is deflected axially and through the fan 22 is supplied to the outflow openings 25 via the surface of the bearing housing 19.
- the mudguard 23 is designed to be non-interrupted in the area of the fan wheel 22 up to some axial distance on the pump side thereof in order to ensure an axial inflow of the cooling air to the fan wheel 22. Furthermore, the axial inflow is secured by the struts 17 of the lantern, which run parallel to the axis and act practically as guide devices.
