Definitions

  • the invention relates to an electric pump, which is particularly suitable for aquariums.
  • Newer pumps have a permanent magnet, which is also driven with 220 V alternating voltage. This results in a certain smoothness, but the use of 220 V AC voltage in and around the aquarium is problematic.

  • the circuit thus represents a three-stage Mul ti vibrator, the frequency of which is determined by the phase shifter.
  • Design of the circuit ensures that only one stage is switched on and the rotating field generated in the motor always rotates in the predetermined direction.
  • the rotor When the current is switched on, some amplifier stage first switches on the associated winding. At this time, the rotor has an arbitrary angular position and is aligned by the switched-on winding in the shortest way, with or against the intended direction of rotation. In the following tilting operations, the armature is pulled synchronously in the predetermined direction with the rotating field, as is the case, for example, with a stepper motor.
  • the rotor induces one in the winding corresponding to the angular position by the rotational steps or angular momentum
  • phase shifters are dimensioned such that the following stage is switched on first and the previous stage is blocked by the following stage via the respective phase shifter. This process is repeated 3 times per full armature revolution, so that the armature is exposed to a constant torque and starts up in a known manner.

  • This configuration of the water outlet connection and the possibility of switching the direction of rotation of the gyro can cause a sea surf or
  • Flow change effect can be achieved, which is indispensable especially in low sea water animals. It is also possible that the first water outlet connection is used as a flow and the second is operated as a skimmer. At the same time, the water intake socket is equipped with a filter and takes over the water cleaning.
  • FIG. 7 shows an embodiment similar to FIG. 6, in which the water outlet connections are arranged at right angles to one another. When the direction of rotation of the gyro changes, the water flow is directed accordingly in a fixed direction.

Abstract

Une pompe, notamment pour aquariums, est pourvue d'un moteur électrique, d'un gyrostat mû par le moteur électrique, d'une tubulure d'admission d'eau et d'une tubulure d'évacuation d'eau connectées au gyrostat. Le moteur électrique présente un aimant (4) diamétralement polarisé et des enroulements (W1, W2, W3) opposés à l'aimant, agencés à la même distance angulaire. Chaque enroulement est connecté via un amplificateur (V/61, V2, V3) correspondant à une source de basse tension de courant continu. L'entrée de chaque amplificateur est connectée via un premier déphaseur (O/32, O/21, O/13) à la sortie de l'amplificateur suivant et via un deuxième déphaseur (O/12, O/23, O/31) à la sortie de l'amplificateur précédent. Cette pompe peut être actionnée par une tension continue de 12 V et présente une grande longévité.
