Title (EN) HIGH-DENSITY POWDER PUMP
(FR) POMPE À POUDRE À HAUTE DENSITÉ
Abstract:
(EN) The present invention concerns a pump for high-density powder transfer. The pump for high-density powder transportation according to the present invention has four-stroke operation, in which four pumping chambers in reality constitute a system of two pairs of chambers in line with each other. This makes it possible to divide the overall flow rate per minute over four tanks. Each of the four tanks has a reduced capacity, to the benefit of the compactness of the pump and the reduction of the loading/emptying times of the single tank, by exploiting the fluid-dynamic principle of communicating vessels the system of pairs of chambers in line increases the overall powder storage volume, thanks to a constant depression.
(FR) La présente invention concerne une pompe de transfert de poudre à haute densité. La pompe de transport de poudre à haute densité selon la présente invention dispose d'un fonctionnement à quatre temps, dans lequel quatre chambres de pompage constituent en réalité un système de deux paires de chambres alignées l’une avec l’autre. Cela permet de diviser le débit global par minute entre quatre réservoirs. Chacun des quatre réservoirs dispose d'une capacité réduite, au profit de la compacité de la pompe et de la réduction des temps de chargement/vidange du réservoir unique, en exploitant le principe de dynamique des fluides des récipients communicants. Le système de paires de chambres en ligne augmente le volume global de stockage de poudre, grâce à une dépression constante.
