Abstract

Dispositivo de cebado (10) para bombas eléctricas (11), que comprende: - unos medios para el llenado automático de un cuerpo de bomba (12) en el arranque, con un líquido que se origina a partir de un mismo depósito (13) desde el cual la bomba eléctrica (11) está diseñada para extraer cuando está en la condición de régimen estacionario, estando dichos medios de llenado automático constituidos por una bomba de vacío (16) que está adaptada para extraer aire desde el interior del cuerpo de la bomba (12) por medio de un conducto de succión (17), - un controlador electrónico (14) para la gestión coordinada de la conexión y la desconexión de dichos medios de llenado automático y del motor eléctrico (15) de la bomba eléctrica (11), y - unos medios sensores del nivel, que deben ser asociados con el cuerpo de la bomba (12) e interconectados con dicho controlador electrónico (14), con el fin de detectar el nivel del líquido en el interior de dicho cuerpo de la bomba (12), caracterizado por que además comprende un aireador automático (18) que tiene un flotador (22), estando dicha bomba de vacío (16) adaptada para extraer aire del interior del cuerpo de la bomba (12) por medio de la interposición de dicho aireador automático (18) fijado en la parte superior del cuerpo de la bomba (12), estando dichos medios sensores del nivel constituidos por un imán (27) que está integrado en dicho flotador (22) y que está encarado a un sensor de posición o de desplazamiento (28), por ejemplo, una bombilla Reed, el cual está dispuesto fuera del cuerpo en forma de copa (19) del aireador automático (18).Priming device (10) for electric pumps (11), comprising: - means for automatically filling a pump body (12) at startup, with a liquid originating from the same tank (13) from which the electric pump (11) is designed to extract when it is in the steady state condition, said automatic filling means being constituted by a vacuum pump (16) that is adapted to extract air from inside the body of the pump (12) by means of a suction pipe (17), - an electronic controller (14) for the coordinated management of the connection and disconnection of said automatic filling means and of the electric motor (15) of the electric pump ( 11), and - level sensor means, which must be associated with the pump body (12) and interconnected with said electronic controller (14), in order to detect the level of the liquid inside said body of the pump (12), characterized in that ad It further comprises an automatic aerator (18) having a float (22), said vacuum pump (16) being adapted to extract air from inside the pump body (12) by means of the interposition of said automatic aerator (18) fixed in the upper part of the pump body (12), said level sensing means being constituted by a magnet (27) that is integrated in said float (22) and that faces a position or displacement sensor (28). ), for example, a Reed bulb, which is arranged outside the cup-shaped body (19) of the automatic aerator (18).
