Title (EN) A PULSATION DAMPER FOR ABSORBING PRESSURE PULSATIONS IN A HIGH PRESSURE HYDRAULIC SYSTEM.
(FR) ATTENUATEUR DE PULSATIONS POUR ABSORBER DES PULSATIONS DE PRESSION DANS UN SYSTEME HYDRAULIQUE A PRESSION ELEVEE
Abstract:
(EN) In order to absorb disturbing pressure pulsations in a high pressure hydraulic system, the transport pipe (15) between source (10) and consumer is cut in at least one place and a damper (16) is mounted. The damper comprises at least one damper pipe (17, 18), having a larger diameter than the transport pipe (15), without normally exceeding an inner diameter of 70 mm. If two or more parallel damper pipes are used, these are connected by means of a part (19) of the long intervening pipe, so that a compact unit is obtained, suited to local conditions.
(FR) Afin d'absorber des pulsations de pression gênantes dans un système hydraulique à pression élevée, la conduite de transport (15) entre la source (10) et le consommateur est coupée en au moins une place et un atténuateur (16) est monté. Ce dernier comporte au moins une conduite d'atténuateur (17, 18), d'un diamètre supérieur à la conduite de transport (15), sans dépasser normalement un diamètre intérieur de 70 mm. Si l'on utilise deux ou plusieurs conduites d'atténuation parallèles, celles-ci sont connectées grâce à une partie (19) de la longue conduite d'intervention, de manière à former une unité compacte, appropriée aux conditions locales.
