Definitions

  • the present invention relates to an alternative, hydraulic cylinder-driven, volumetric pump characterized by its high-volume, square, hermetic construction as duplex, i.e., having two housings one on each side of the cylinder and being of double action, that is, it pumps in both directions of the cylinder stroke.
  • Alternate displacement displacement pumps whether simplex or duplex, single or double acting, are cylindrical, which limits the maximum volume pumped and therefore the delivered flow; in addition they are sealed through gaskets, which makes it very difficult to make a large diameter.
  • the main purpose of the invention is to provide a higher flow rate, displacing large volumes and being hermetic, ie without risk of leakage to the environment, through its innovative geometry and hydraulic drive.
  • the invention has the advantage of providing a higher flow rate compared to the existing alternative volumetric pumps, being feasible its application to the transport of highly viscous fluids, such as ultra-heavy oil, without
  • Removable scrapers (5) are provided on the pistons as well as removable wear plates (2), making maintenance quick and easy.
  • duplex construction pumps two volumes of the casing in each cycle of the hydraulic cylinder and the double action refers to the use of the two strokes of the pump cycle, taking full advantage of the work provided by the cylinder.
  • Figure 1 cross-sectional detail of the double-action duplex hermetic square pump.
  • Figure 1 shows the duplex double sealed square pump, with two square rectangular shells (1) coated wear plates (2), the square pistons with scrapers (3), driven by the hydraulic cylinder (4). ) and the seals (5) and the seal chamber (6).

Abstract

La présente invention concerne une pompe volumétrique actionnée par cylindre hydraulique (4), caractérisée en ce qu'elle est hermétique, duplex, à double action, avec boîtiers rectangulaires de section carrée à haut volume (1) revêtus de plaques d'usure (2), comportant des racleurs amovibles (5) situés aux extrémités des deux faces du piston, avec pour avantage de pouvoir déplacer de grands volumes, d'où une utilité optimale pour le transport de fluides hautement visqueux et de pulpes avec solides en suspension.
