Definitions
- the present invention relates to a pump with integrated, electronically commutated wet-rotor motor.
- a shaft rotates with a rotor of the motor in a rotor chamber and an impeller of the pump in a hydraulic chamber.
- a bearing plate with a plain bearing for supporting the shaft and a rubber seal to protect the sliding bearing against contamination and corrosion by the water.
- This bearing shield prevents water from flowing from the hydraulic chamber into the rotor chamber. If a defect occurs on the sealing rubber, the water can enter the rotor chamber. This contamination by the water and corrosion can cause damage to the sleeve bearing and the rotor chamber.
- the object of the invention is to provide a pump with integrated, electronically commutated wet-rotor motor, which is protected in a simple manner against damage.
- the pump has a one-piece pump chamber comprising a rotor of the wet rotor motor.
- This design makes it possible to constantly clean the pump chamber during the pumping process by water flow, so that no strong contamination of the water occurs.
- Another advantage is that in this design, the rotor can be cooled by the water flow.
- the pump chamber is formed by a front housing shell and a shield of the engine.
- the shield is cup-shaped. In this way, the rotor can be covered by the shield with the least possible gap, resulting in a high volume utilization of the engine.
- the pump has a rotationally mounted axle on which the rotor is rotatably mounted.
- the axle is mounted in the shield, in particular for vibration damping in at least one O-ring, which is preferably made of rubber.
- the rotor is supported by at least one radial sliding bearing on the axle. In this way, the life of the sliding bearing is increased because it rotates together with the rotor on the axis.
- the radial sliding bearing is held in the rotor by an O-ring.
- tolerances in the plain bearing receptacle of the rotor can be compensated by the elastic O-ring, so that the sliding bearing is concentric on the axis.
- vibrations of the rotor are damped by the O-ring, so that the requirement for vibration damping of the axle can be reduced.
- the rotor is supported by a thrust bearing on the axle.
- This has the advantage that the thrust bearing reduces axial play of the rotor.
- the sliding bearing and / or the thrust bearing on a liquid seal, in particular with a sealing rubber and / or an O-ring.
- a sealing rubber and / or an O-ring In this way, the plain bearing and / or the thrust bearing is sealed during the pumping process, so that a water flow through the sliding bearing and / or by the axial bearing is prevented and thus no corrosion can occur in the bearings.
- the rotor has an interior which is subdivided into two subregions tapering conically towards one another.
- a predetermined breaking point is provided in two parts for entered into the interior and freezing water, whereby the on the rotor in radial and axial direction tensile stresses can be reduced.
- the two sections are arranged between two radial plain bearings, wherein the two radial plain bearings are each held in the rotor with an elastic O-ring, so that the freezing water can expand in the axial direction by slight displacements of the radial plain bearings.
- the rotor has an impeller.
- the impeller is integrally formed on the rotor. In this way, an assembly of the pump is simplified, since the number of separate components is reduced.
- the rotor is plastic coated. This ensures in a simple manner that the rotor is waterproof. The epicn thus is a one-piece design of the rotor with the impeller made of plastic very easy to perform.
- FIG. 1 shows in a first embodiment and FIG. 2 shows in a second embodiment a section through the pump according to the invention with integrated, electronically commutated wet-rotor motor.
- the housing of the pump 1 is composed of a front housing shell 2 and a pot-shaped shield 3, which are both positively connected to one another.
- the housing of the pump 1 forms a one-piece pump chamber 4, which comprises in its interior a rotor 5 with an impeller 6.
- the impeller 6 is integrally formed on the rotor 5.
- the rotor 5 is rotatably mounted on a shaft 9 by a front, the impeller 6 facing slide bearing 7 and by a rear, the shield 3 facing slide bearing 8.
- the rotor 5 is fixed at its two ends by a respective clamping ring 10, 11 according to FIG.
- the rotor 5 at its front, the impeller 6 facing the end to Reduction of the axial movement of a thrust bearing 12, with a socket for an O-ring 13 between the thrust bearing 12 and the sliding bearing 7.
- the O-ring 13 By the O-ring 13, the sliding bearing 7 against a liquid inlet, in particular against a water inlet, sealed and in radial Direction elastically centered.
- a rubber shock absorber 14 is inserted between the thrust bearing 12 and the clamping ring 11, a rubber shock absorber 14 is inserted.
- the axis 9 is at its front, the impeller 6 end facing in a seat 15 which is fixed by support arms 16 to the front housing shell 2, and at its rear, the shield 3 facing the end in a seat 17 which is in the shield. 3 is formed rotatably mounted.
- a compensation element 18 is inserted, which is preferably designed as a rubber disc to compensate for axial changes in length of the axis 9 with temperature fluctuations can.
- the axis 9 is fixed in the seat 17 of the shield 3 by an O-ring 19.
- the O-rings 13, 19 as well as the compensation element 18 made of rubber, so that vibrations of the rotor 5 and thus the axis 9 can be absorbed.
- the entire rotor 5 is plastic coated. From the same plastic, the impeller 6 of the pump 1 is formed on the rotor 5.
- the rotor 5 and the impeller 6 can be manufactured as one piece. This one-piece design is not mandatory, but has the advantage that the number of components is smaller and the problem of fixing the impeller 6 on the rotor 5 is bypassed.
- stator 21 of the wet-rotor motor is arranged, so it is a so-called internal rotor. It is also an embodiment as an external rotor possible.
- the electrical connection of the stator 21 is in the form of a resilient contact 22 to an electrical drive circuit, which is arranged on a circuit board 23. In this way it is possible to mount the pump 1 without a special soldering tool.
- the board 23 is covered by a rear housing shell 24 which is connected by screws 25 to the stator 21 and the cup-shaped shield 3.
- the impeller 6 In order to improve the flow characteristics within the impeller 6, sits on the axis 9 as a final piece in front of the front, the impeller 6 facing clamping ring 11 a shaped head 26 which separates the clamping ring 11 of the water-conducting portion 27 of the impeller.
- the shape of the head piece 26 is adapted to the shape of the impeller 6 such that the flow resistance is minimal.
- a gap seal 28 is formed, in which the impeller 6 rotates.
- the radial slide bearings 7, 8 are held in the rotor 5 by a respective elastic O-ring 30, 31.
- these O-rings 30, 31 serve to compensate for tolerances in the plain bearing receptacle of the rotor 5, so that the plain bearings 30, 31 sit concentrically on the axis 9.
- vibrations of the rotor 5 are damped by the elastic O-rings 30, 31. Therefore, in comparison to the first embodiment according to FIG. 1, the O-ring 19 in the seat 17 of the shield 3 and the rubber shock absorber 14 for vibration damping of the axle 9 can be dispensed with.
- the functionality of the clamping ring 11 according to FIG. 1 is already integrated into the head piece 26, so that this further component can be dispensed with.
- the interior of the rotor 5 is divided into two conically tapered sections 32, 33. If water enters this interior space of the rotor 5 between the two plain bearings and freezes this water to ice, it breaks up into two parts corresponding to the partial areas 32, 33. When expanding, these two parts can press the radial slide bearings 7, 8 to a slight extent in the axial direction outwards, so that tensile stresses on the rotor 5 are reduced both in the radial and in the axial direction.
- the pump 1 is designed in particular for use in water-conducting household appliances, such as dishwashers.
