Definitions

  • the invention relates to a device for switching pumps on and off electromotively, in particular submersible pumps, in which the switching process takes place depending on the liquid level in a container or other collecting space with the aid of a float which at the end of a fixed pivot point up and down movable Supply cable is arranged, which leads to an electric switch arranged in the float, which is controllable by a weight carried by the float, which is displaced in one of two directions on the predetermined path during the float movements.
  • PRIOR ART Background Art
  • the track on which the weight shifts due to the float movements is arranged in the direction of the cable.
  • the invention provides in a device of the type described above for switching on and off electromotively driven pumps with a float and a weight that moves along a predetermined path and controls a switch under the influence of the float movements, that the movement path for the switch controlling weight to the plane, which is determined by the pivoting movement of the supply cable holding the float and connected to the switch, is inclined at an angle which deviates more or less strongly from the perpendicular to this plane.
  • the path for the control weight of the switch should preferably lie in a plane that is perpendicular to the plane of the pivoting movement of the supply cable. It should run through or about the pivot point of the cable.
  • the positional stability of the control weight in the switch positions is further increased by the fact that the supply cable can be rotated to a certain extent about its longitudinal axis.
  • the movement path of the control weight will primarily be straight. However, if this should be expedient, it can be made in any other way, in particular curved and, for example, arc-shaped. If necessary, the course of the
  • the movement path of the control weight on the movement path can also be designed to be changeable and / or adjustable.
  • two control weights displaceable on different tracks could also be provided, by one of which controls the electrical switch while the other controls the switching position.
  • the float 11 shown in FIG. 1 of a device for switching pumps on and off by electric motor is usually arranged at the end of a cable 12 which is fastened at a certain distance from the float. With the changes in the liquid level, the float 11 rises and falls and pivots the cable up and down in a plane perpendicular to the plane of the drawing.
  • the float 11 serves as a housing for a switching device which has the actual switch 13, for example a so-called microswitch of conventional design, and a switching weight serving to control it, in the form of a ball 14, which is influenced by the float's lifting and lowering movements of their weight on a straight line
  • Path 15 can move back and forth and acts on the switching lever 131 of the microswitch.
  • the path 15 on which the ball 14 moves lies in a plane which is approximately at right angles to the plane in which the cable 12 moves up and down with the float 11.
  • the path of movement 15 for the ball 14 intersects this plane of the pivoting movement of the cable 12 at an angle which deviates more or less from a right angle. In the illustrated embodiment, this angle is approximately 20 ° or 110 °. Due to such an arrangement of the track, as soon as a certain level is exceeded or undershot, the ball moves from one end of the track to the other end, the shift lever 131 then being depressed or released.
  • a floating body is shown in the drawing, which is displaceably arranged on the float housing and fulfills a function similar to that which can be achieved by a deliberate asymmetrical clamping of the cable that guides the float.
  • the extent of the asymmetry can be changed and adjusted by displacing the buoyancy body, which is clamped on the float housing.

Abstract

Dispositif pour enclencher et declencher une pompe actionnee par un moteur electrique, en particulier une pompe immergee, en fonction du niveau du liquide d'un reservoir a l'aide d'un flotteur (11) dispose a une extremite d'un cable d'alimentation (12). Ce cable aboutit a un interrupteur (13) place dans le flotteur (11) et peut se deplacer verticalement par rapport a un point fixe de pivotement. L'interrupteur (13) est commande par un poids (14) porte par le flotteur (11) et qui peut se deplacer en un mouvement de va-et-vient sur un chemin (15) sous l'influence des mouvements du flotteur.Le chemin (15) sur lequel se deplace le poids est incline par rapport au plan defini par le mouvement de pivotement du cable (12) retenant le flotteur (11), l'angle d'inclinaison s'ecartant plus ou moins fortement de la perpendiculaire a ce plan. Selon une forme particuliere d'execution de l'invention, le chemin (15) sur lequel se deplace le poids (14) est situe dans un plan perpendiculaire au plan de pivotement du cable.
