Definitions
- the invention relates to a motor pump unit comprising an electric motor and a pump.
- the motor and pump are interleaved; the Motor envelops the pump.
- EP 0 611 887 A1 describes a further motor pump unit.
- the rotor of the motor is an independent component, but with the cylinder block a piston pump rotatably connected.
- Units of this type have the great advantage that they only have one occupy minimal space. But there is still room for improvement.
- the invention has for its object a motor pump unit mentioned design to improve even further, especially with regard to the Manufacturing effort and space requirements.
- the invention is based on the aforementioned WO document, but with one Multiplication of the individual units.
- a preferred Embodiment comprises the entire motor pump unit two axially internal gear pumps aligned with one another and an electric motor which which is assigned to one of the two pumps. They are each other neighboring pumps are assigned to each other in such a way that they single electric motor can be driven. It gets involved with it achieve high delivery volume and / or high delivery pressure.
- a large The advantage is that the two pumps are within a single housing are arranged so that when operating the entire aggregate of oil are enclosed and therefore no seals are required.
- the two pumps can be completely identical. But you can too have different diameters in the conveying area, i.e. where the Conveyor tooth limit.
- Asynchronous motors for example Asynchronous motors, reluctance motors or so-called squirrel-cage rotors.
- the invention can be used particularly advantageously in the case of internal gear pumps apply.
- the pump forms a completely independent, self-sufficient unit. It can be Manufacture separately, check separately and completely in the stator of the Install the electric motor enclosed space.
- the engine is cooled with oil.
- the motor pump unit comprises an electric motor 1 with a Stator laminated core 1.1, a winding 1.2 and a rotor 1.3.
- first internal gear pump 2 This has a pinion 2.1 on, a compared to this eccentric ring gear 2.2 and a pinion shaft 2.3.
- the pinion shaft 2.3 is mounted in side windows 2.4, 2.5.
- the two elements, motor and first pump, are common Enclosed housing 3.
- housing 3 In the housing 3 there is an inlet 3.1 and a first outlet 3.2 for the medium to be pumped.
- the rotor 1.3 of the motor 1 is pot-shaped. In the present axial section it appears U-shaped.
- the pinion shaft 2.3 projects with the rotor 1.3 a toothing 2.3.1 in rotary connection.
- web 1.3.1 of the U is namely an internal toothing, while the pinion shaft a corresponding Has external teeth. Comb the internal teeth and external teeth together.
- the rotor 1.3 is mounted on the first pump 2, more precisely on the Ring gear 2.3 and the side windows 2.4, 2.5.
- a second internal gear pump is provided. This is arranged axially next to the first pump 2, in such a way that the The axes of the two pumps are aligned.
- the housing 3 is over the led out first pump 2 and flows around the second pump 20th
- the second pump 20 is identical in construction to the first pump 2. It has accordingly also a pinion shaft 20.3, which with the pinion shaft 2.3 is structurally identical and which also has a toothing 20.3.1 with the rotor 1.3 is in rotary connection.
- the housing 3 has a second outlet 3.3.
- the second pump 20 is fixed on the right cover of the housing 3.
- the cup-shaped rotor thus drives 1.3 the two pinion shafts 2.3, 20.3.
- the course of the oil is shown by the bold arrows.
- the oil will at inlet 3.1, shown in the figure on the left, sucked in, passes through the gap between the stator laminated core 1.1 and the rotor 1.3 in the space between the two pumps 2 and 20.
- the oil flow divides there.
- a partial flow occurs through the pump 2 and at the first outlet 3.2 again, and on second partial flow passes through the second pump 20 and on the second Spout 3.2 out.
- the motor pump unit thus has a suction connection and two pressure connections.
