Title
(EN) SUCTION RAM DEVICE, NOTABLY FOR A WELDING ROBOT ELECTRODE COOLING SYSTEM
(FR) DISPOSITIF DE VERIN D'ASPIRATION, NOTAMMENT POUR UN SYSTEME DE REFROIDISSEMENT D'ELECTRODES D'UN ROBOT DE SOUDAGE.
Abstract
(EN)
Suction ram device 21 for a fluid circuit having, on either side of a removable load 2: an upstream pipe 13 and a downstream pipe 14, a feed pipe 11 and a discharge pipe 12, a shutoff valve 17 designed to isolate the upstream pipe from the feed pipe, and a shutoff valve 18 to isolate the downstream pipe from the discharge pipe, the fluid being kept more or less at an inlet pressure PI in the feed pipe and at an outlet pressure P2 in the discharge pipe, the inlet pressure being higher than the outlet pressure, characterized in that it comprises a suction ram 24 operated by the difference in pressure between the feed pipe and the discharge pipe.
(FR)
Dispositif 21 de vérin d'aspiration pour un circuit de fluide ayant, de part et d'autre d'une charge amovible 2: une conduite amont 13, et une conduite aval 14, une conduite d'alimentation 11 et, une conduite d'évacuation 12, une vanne d'arrêt 17 disposée pour isoler la conduite amont d'avec la conduite d'alimentation, et, une vanne d'arrêt 18, pour isoler la conduite aval d'avec la conduite d'évacuation, le fluide étant sensiblement maintenu à une pression d'entrée P1 dans la conduite d'alimentation et à une pression de sortie P2 dans la conduite d'évacuation, la pression d'entrée étant supérieure à la pression de sortie, caractérisé en ce qu'il comprend un vérin d'aspiration 24 commandé par la différence de pression entre la conduite d'alimentation et la conduite d'évacuation.
