    摘要: Les pompes a diaphragme sont utilisees pour pomper des liquides et comprennent des tiges passant au travers d'une enceinte pour effectuer le mouvement de retour du diaphragme. Cette invention se rapporte a une nouvelle pompe a diaphragme qui evite d'utiliser ces tiges. La nouvelle pompe possede une chambre a air (26) et une chambre de pompage (30) separees par un diaphragme composite (16, 18). L'alimentation en air comprime dans la chambre a air (26) deplace le diaphragme qui effectue un mouvement de pompage. Le mouvement de retour du diaphragme s'effectue par evacuation de la chambre a air (26) tout en alimentant en air comprime une autre chambre a air formee entre la premiere membrane (16) et la deuxieme membrane (18) du diaphragme composite. La difference de surface entre les membranes est suffisante pour que le diaphragme composite (16, 18) se redresse de lui-meme pour tirer le fluide dans la chambre de pompage (3) prete au mouvement de pompage suivant du diaphragme.

    摘要: A vacuum system for use with a deoxygenator system includes a housing (42), a movable assembly (44) positioned within the housing (42), and a biasing mechanism coupling the movable assembly (44) to the housing (42). The movable assembly (44) is movable between a first position and a second position within the housing (42) to form a low pressure area between the housing (42) and the movable assembly (44). A control system (90) including at least one pressure source is arranged in fluid communication with the low pressure area. The control system (90) is operable to selectively communicate fluid from the at least one pressure source to the housing (42) to form the low pressure area.

    摘要: Cette installation de pompage (16) comprend une pompe pneumatique (22) pour pomper un fluide (12) et un système (24) d'alimentation de la pompe pneumatique (22) en gaz comprimé. Le système d'alimentation (24) comprend une source (34) de gaz comprimé et une liaison fluidique (36) reliant fluidiquement la source (34) à la pompe pneumatique (22). L'installation de pompage (16) comprend également un système (38) de régulation de l'alimentation de la pompe pneumatique (22) en gaz comprimé, ledit système de régulation (38) comprenant une vanne (40) montée sur la liaison fluidique (36) et permutable entre un étant bloquant, dans laquelle la vanne (40) empêche la circulation de gaz comprimé entre la source (34) et la pompe pneumatique (22), et un étant passant, dans laquelle la vanne (40) permet la circulation de gaz comprimé entre la source (34) et la pompe pneumatique (22).

    摘要: The ultra-high pressure booster or intensifier is a device consisting of two cylinders with two pistons, connected such that they operate simultaneously, which can be mounted in a multi-chamber containing simple pressure boosters nested (not mounted in series or in parallel) that can be used to increase the ultra-high pressure depending on the simple boosters being used. According to the invention, a flow of gas or liquid enters at pressure P1 and once filled at pressure P1, the flow enters into a simple pressure booster which is located inside chamber 1 and divides the flow into two parts: one part that is increased to pressure P2 and housed in another chamber 2 located inside chamber 1, using the energy released by the other part which is reduced to pressure P0 and released from the chamber 1. After several displacements when chamber 2 is at pressure P2, another simple pressure booster begins to operate, which is located inside the chamber 2 and divides the flow into a part that is increased to pressure P3 using energy from the other part which is reduced to pressure P1. After several displacements, chamber 3 is at pressure P3 and a new simple pressure booster and another chamber 4 are ready to continue increasing the pressure. In this way, with new boosters an ultra-high pressure Pn, as high as required, can be reached in chamber n. Each chamber can be formed by multiple walls or a series of sub-chambers, allowing greater resistance to be achieved. The invention can be used for ultra-high pressure sintering, preparing sterilized foodstuffs using ultra-high pressure or cutting materials, among others.
