Definitions
- the invention overcomes these drawbacks with a less pump bulky, less prone to breaking down and which allows emptying completely the sump.
- the pump according to the invention has a waterproof casing and vents suction opening at the bottom of the pump. It is characterized by a static liquid presence detector, which is mounted in the manifold discharge at a level lower than that of the mouth of the tubing of discharge and by an on / off circuit of the pump motor controlled by the detector.
- a pressure sensor an optical sensor emitting a laser beam which will be interrupted when there is presence of liquid putting thus the pump in operation and stopping it when the beam is restored by the presence of air
- an ultrasonic generator emitting a beam which will be interrupted when water is present, thus putting the pump in operation, it stops when the ultrasound reappear in the presence of air
- a temperature probe which, in the presence of cold liquid, will start the pump motor.
- the detector can also be a capacitive sensor activating an oscillator emitting a frequency which will different in the presence of liquid for start-up and in the presence of air for the stop.
- the detector can also be a piezoelectric sensor generating vibrations which will be damped in the presence of water for setting on the way. When the pump no longer delivers by the presence of air, the sensor will stop the pump. You can also use a flexible membrane which, under static pressure and under pressure from the pump in operation, will deform a membrane, which will activate a pump start switch.
- the pump shown comprises a casing 1 sealed against inside which a wheel 2 is mounted rotating relative to the axis x, x ' of the pump. Below the wheel 2, the pump has a base on which it is erected with its vertical x, x 'axis. 3 suction outlets open out at the lowest point of the pump.
- Wheel 2 is driven by an electric motor 4 with electronic control plate 5. Along a side of the motor extends the delivery pipe 6. This tubing is vertical and communicates with the wheel 2.
- the mouth 7 of the tubing of discharge to the outside is at the highest point of the pump. At one level lower than that of the mouth 7 is mounted in the tubing 6 a detector 8 fixed and static capable of detecting the presence of liquid at its level in the tubing 6. This detector 8 is connected by an on / off circuit 9 to the plate 5 for controlling the motor 4 of the pump.
- the detector 8 detects the presence of liquid as soon as that it arrives at its level and, via circuit 9 and the circuit board 5, controls the starting of the motor 4 and therefore of the pump. That; ci sucks the liquid through the vents 3, the wheel 2 and the tubing 6 to discharge it by mouth 7, as shown by the arrows in the drawing. As long as there is the water in the sump, this operation continues and it is only when there is more liquid than the detector 8 controls the stopping of the engine 4.

Abstract
Description
Claims (5)
- Pompe à enveloppe étanche et à ouïes (3) d'aspiration débouchant au bas de la pompe, caractérisée par un détecteur (8) statique de présence de liquide, qui est monté dans la tubulure (6) de refoulement à un niveau inférieur à celui de l'embouchure (7) de la tubulure (6) de refoulement et qui est apte à détecter la présence de liquide à son niveau et par un circuit (9) de marche/arrêt du moteur (4) de la pompe commandé par le détecteur (8).
- Pompe suivant la revendication 1, caractérisée en ce que les ouïes (3) débouchent au point le plus bas de la pompe.
- Pompe suivant la revendication 1 ou 2, caractérisée en ce que le détecteur (8) commande le circuit de marche/arrêt du moteur en arrêtant le moteur (4) quand il ne détecte plus de liquide.
- Pompe suivant la revendication 1, 2 ou 3, caractérisée en ce que le détecteur (8) est un capteur de pression, un capteur optique, un générateur d'ultrasons, une sonde de température, un capteur capacitif, un capteur piézo-électrique ou un capteur à membrane souple.
- Pompe suivant l'une quelconque des revendications 1 à 4, caractérisée en ce que l'axe (x,x') de la pompe est vertical.
