Definitions

  • the invention relates to a motor pump with a pump head and an electric motor driving the pump head according to the preamble of the preamble of claim 1 or of a method for producing such a pump according to the preamble of claim 13.
  • Such motor pumps serve the transport or the pressure increase of a liquid and are used for some time, for example, as water pumps in heating circuits.
  • a pump-motor unit which serves as a cooling water pump of a motor vehicle internal combustion engine.
  • a centrifugal pump which is driven by an electronically commutated DC motor.
  • the centrifugal pump and the DC motor are connected to each other via a heat sink.
  • an existing of a suitable material gap pot is clamped, the runners of the Electric motor disconnects from the stator.
  • a seal introduced between the pump housing and the split pot seals the liquid-filled rotor chamber from an outer stator chamber.
  • a canned motor for pumps is disclosed with a split pot disposed between the rotor and the stator.
  • the stator has a thin-walled sleeve-shaped, in particular laminated main body.
  • This main body carries on its outer side radially aligned webs which carry the stator winding and lies with its cylindrical inner side at least partially on the outside of the can.
  • Another disadvantage here is the complex installation and sealing of the additional containment shell.
  • the split tube must be installed and sealed between the stator pack and the rotor.
  • the control and regulating electronics of the canned motor EP0713282 is designed as a module and requires one elaborate cooling.
  • the electronics module rests positively with its one side of the housing on the stator winding.
  • the heat energy generated by the electronics is discharged via the switch housing to the motor housing with the stator winding located therein. This in turn transfers the heat energy absorbed via the containment shell to the pumped medium.
  • a water delivery pump in which a water delivery vane is rotatably disposed in a water passageway and in which a rotor on which a plurality of permanent magnets are disposed such that on the inside and outside of the poles of the adjacent ones alternately alternate with each other, coaxial with the water delivery vane is connected and in which at the periphery of the rotor magnetic coils are arranged at a distance from the water conduit through a non-magnetic material consisting of a cylindrical partition wall.
  • the water pump of the JP 7-208380 has a plurality of metal pieces made of a magnetic substance corresponding to the magnetic poles of the rotor embedded in the partition wall.
  • a motor pump known, consisting of a centrifugal pump, which has a spiral housing with a suction nozzle and a discharge nozzle, and a drive motor and a cooled by the flow of the pump, internal frequency converter for controlling the speed of the motor.
  • this is characterized by the fact that between the centrifugal pump and the drive motor, a cooling wall is provided, said motor side at least the power section of the frequency converter is arranged on this cooling wall and in that between the outlet cross section of the conveyor spiral of the volute casing and its discharge nozzle is formed along the cooling wall along, with this standing in heat exchange action and the conveying medium from the delivery spiral to the discharge nozzle conductive delivery channel is formed
  • a speed-controlled pump unit for conveying liquids or gases known, which consists of a pump and a pump driving Electric motor exists.
  • the speed of the motor can be changed by a voltage regulator.
  • the miniaturized by the application of highly integrated circuits voltage regulator is arranged in or on the unit and forms with this a structural unit. In this way it is possible that the heat loss of the voltage regulator can be dissipated with the demanded by the unit and to be delivered fluid as a heat sink.
  • the pump according to the invention with the features of claim 1 has the advantage that in a simple manner, the seal of the pumped medium to open the rotor space is made possible with respect to the stator and in addition a good cooling of the electronics of the pump chamber is achieved.
  • the sealing wall of the split pot belongs directly to the stator, can be dispensed with the additional component of a split tube.
  • the assembly step eliminates the introduction of the split tube between the stator and the rotor, which leads to a corresponding simplification and cost reduction in the manufacture of the pump according to the invention.
  • this sealing wall can be formed as a completely closed in the circumferential direction of the rotor space shell of the stator.
  • This jacket of the stator can be made in a simple and advantageous manner from plastic or other suitable material.
  • a wall made in one piece with the motor housing gives the pump according to the invention the necessary mechanical stability and at the same time it can contribute to the sealing of the rotor space.
  • the one-piece engine housing with the executed wall for sealing the rotor space can be made of metal in particular, which is for strength and heat-Qbertraguagshuntn advantage.
  • the use of only one metal part for the pump housing of the pump according to the invention is possible, which leads to a significant cost reduction of such a pump
  • An advantageous embodiment of the pump according to the invention results from the fact that the pump head, the electric motor driving this pump head and an electronic switching part, which serves to control the electric motor, are arranged together in a housing.
  • This housing may be a one-piece housing or consist of several components, which are assigned to the individual functions (pump, motor, switching part) and which are interconnected.
  • the motor housing can be used at the same time as a housing part and also as a heat sink for the electronics.
  • a jacket of the stator with a plastic offers the advantage that the pole teeth of the stator, which may be formed for example by discrete laminations, can be injected directly into the plastic in a simple and advantageous manner and thus fixed.
  • the sealing element between the rotor and stator a row can be transmitted by other functions that a separate can in the original sense can not meet.
  • the stator lamination can be fixed by injection and secured, for example, against rotation. This means a simple and secure fixation of the laminated cores.
  • the overmolded stator also makes it possible to directly form the necessary winding bodies of the stator winding during the injection process. Required contact pockets for the connection of the stator winding can be as well as other required mounts on the stator in an advantageous manner in the injection process with directly molding. All this simplifies the construction and sealing of the stator, reduces the number of components and thus facilitates the assembly of the pump according to the invention. This can not be achieved with a canned pump of the conventional design.
  • stator is connected to a motor housing wall, in particular to a wall made of metal, then this wall can absorb the resulting forces and moments. Due to its thermal conductivity, this metal wall can then also be used directly as a heat sink for the electronics of the pump motor. A good cooling of the electronic switching elements results when they are applied directly to the metal wall.
  • a heat conducting film between the component and heat sink can be placed. It is conceivable to press the power components of the electronics via springs to the cooling surface or to couple them thermally via an electrically insulating adhesive directly to the cooling surface. This ensures good heat transfer from the power component of the electronics to the metallic motor housing.
  • a further significant improvement in the cooling of the elements of the control electronics can be achieved if the metallic cooling wall in turn is additionally actively cooled.
  • the metallic cooling wall in turn is additionally actively cooled.
  • a part of the fluid to be pumped past the cooling wall on the motor side is possible because the expected cooling water temperatures of the internal combustion engine come to lie below the ambient temperatures.
  • a pressure-side opening is provided in the pump head, which creates a connection to the suction side of the pump via a channel in the common shaft of the electric motor with the impeller.
  • the electric motor is arranged between the switching part with the power electronics and the pump head.
  • An electronically commutated DC motor which can drive the pump, ensures an exact control of the coolant flow, for example, adelisteria heating circuit of a motor vehicle with an internal combustion engine. This in turn allows a precisely adapted heat dissipation and thus, among other things, an optimal efficiency and fuel consumption of the vehicle engine.
