Abstract

L'invention concerne une pompe de circulation de fluide, comprenant un corps comportant une zone de circulation du fluide depuis une ouverture d'aspiration vers une ouverture de refoulement, et un moteur électrique 24 contrôlé par une commande électronique 22, et comportant une partie fixe 30 comprenant un stator 24b logé dans une carcasse 31 solidaire du corps, et une partie mobile 20 comprenant un rotor logé dans un tube porteur 24a fermé et en liaison étanche avec une paroi 32 fermant la carcasse. La carcasse, le tube et la paroi délimitent une chambre étanche comprenant un élément 24a, 32 déformable ou déplaçable sous la pression du fluide circulant dans la zone de circulation. Dans la chambre, un capteur 40 connecté à la commande permet de mesurer un déplacement ou une déformation de l'élément, sans contact avec le fluide.The invention relates to a fluid circulation pump, comprising a body comprising a zone for circulation of the fluid from a suction opening to a discharge opening, and an electric motor 24 controlled by an electronic control 22, and comprising a fixed part 30 comprising a stator 24b housed in a carcass 31 integral with the body, and a movable part 20 comprising a rotor housed in a closed carrier tube 24a and in sealed connection with a wall 32 closing the carcass. The carcass, the tube and the wall define a sealed chamber comprising an element 24a, 32 which can be deformed or moved under the pressure of the fluid circulating in the circulation zone. In the chamber, a sensor 40 connected to the control makes it possible to measure a displacement or a deformation of the element, without contact with the fluid.
