Definitions

  • the invention relates to a pump of the type described in the preamble of claim 1, known from DE-GM 19 51 826
  • Conventional pumps essentially consist of two components, namely a drive motor and a gyroscope device coupled to the output shaft of the motor, which effects the circulation of the liquid medium by means of fins or a gyroscope.
  • the medium is rotated by 90 °.
  • This has the disadvantage that part of the power expended is already lost within the system, which consequently results in a loss of pressure or thrust.
  • several such pumps can only be connected in series with considerable effort, since the output must be dimensioned much smaller.
  • specially designed channels must be installed for cooling.
  • a pump which essentially comprises a stator having a stator winding and a coaxial tube-shaped rotor therein.
  • the rotor here comprises a rotor winding and a short-circuit ring. Since the rotor has to take up the rotor winding, one is proportional
  • a magnetic tube is used as a rotor according to the invention, a rotor winding and a short-circuit ring can be dispensed with. In addition, no separate cooling measures are required, since the medium flowing through the rotor is sufficient for cooling the rotor and the stator winding. Another advantage is that the rotor according to the invention can be used both when supplying the stator winding with alternating current and with direct current.
  • the pump according to the invention can also be used in aquariums. Due to its high performance, the pump can be used both directly in and outside of the medium.
  • Fig. 1 shows a longitudinal section through the pump and Fig. 2 is a detail 1 ansi cht, which clarifies the tube provided with drive fins and the bearing of the central axis.
  • the centrally arranged rotor 1 of the pump consists of a tube 1 'made of magnetic material, which is composed of two tube halves, one tube half forming a south pole and the other half forming a north pole.
  • drive fins 2 are provided, which are connected at one end to the inner wall of the tube 1 'and at the other end to an axle bearing 3 provided in the middle of the tube.
  • the number and the angular position 1 of the drive lamellae 2 are based on the desired characteristics for the pump.
  • the axle bearing 3 is rotatably mounted on a central axis 4, which in turn is fixed with its ends in rubber halves 5.
  • the rubber halters 5 are arranged via a receptacle with the help of webs 6 in the center of the inlet or outlet nozzle 7, 8 of the pump, which provide no significant resistance to the medium.
  • the central axis 4 is preferably made of ceramic, which ensures long-term continuous operation by self-lubrication.
  • the rubber bracket 5 allows a certain vibration damping and easy replacement of the central axis 4th
  • the above structure ensures that the tube 1 'with the drive plates 2 can rotate about the axis 4 located in the middle. By this rotation, the medium to be pumped is conveyed in a straight line from inlet connector 7 via the hollow space of tube 1 'to outlet connector 8.
  • the stator surrounding the rotor 1 consists of a tube 9 serving as a seal, the inside of which is arranged at a short distance from the outside of the rotor 1.
  • a stator winding 10 is arranged on the outer circumference of the tube 9.
  • the other side of the stator winding 10 is enclosed by a magnetic sheet core 17.
  • tubular axle bearing 3 - magnetic tube 1 '- tube 9 - stator winding 10 - magnetic sheet steel ring core 17 - housing wall 11.
  • the front housing parts 12 and 13 have the inlet and outlet connections 7 or 8, which are aligned with the tube 1 '.
  • the actual power transmission takes place without contact from the stator winding 10, which is connected via a power supply cable 16 to a power source, not shown, to the magnetic tube 1 '.
  • the conveyor system in the form of the tube 1 ' is thus in a channel hermetically sealed by the tube 9 to the stator.
  • the parts located on the outside of the tube 9 are poured into a casting compound 14 in accordance with the medium to be pumped, which increases operational reliability.
  • the medium delivered through the center of the pump simultaneously causes a uniform cooling of the stator winding 10 via the tube 9.
  • the pump described above can be designed for 12 V DC voltage as well as for 24 V, 110 V or 220 V AC voltage. r-
  • a pump output of up to 12,000 liters per hour can be achieved.
  • the characteristic values, quantity and pressure can be adapted to the requirements. Potting all cavities eliminates the risk of a short circuit, so that the pump can also be used with explosive media. Due to the simple reversal of the conveying direction described above, the pump can also be used as a flow pump.

Abstract

Pompe, notamment pour milieux liquides, comportant un moteur d'entraînement constitué d'un rotor et d'un stator, et un système centrifuge comprenant des lamelles d'entraînement (2) ainsi qu'une tubulure d'admission (7) et une tubulure d'évacuation (8). Le rotor, en tant que système centrifugal, a la forme d'un tube (1) sur lequel sont fixées les lamelles (2) et qui est aligné avec les tubulures d'admission et d'évacuation (7, 8) de la pompe. Dans cette dernière, le milieu s'écoule en ligne droite, dans le sens axial du moteur d'entraînement ou de la pompe, ce qui permet un redement optimal. Grâce à son fonctionnement particulièrement silencieux, ladite pompe s'utilise également dans les aquariums. Son redement élevé lui permet d'être utilisée aussi bien directement dans le milieu qu'en dehors de celui-ci.
