PANEQUE RONDON, Pedro et al. Evaluation of two hydraulic gears pumps of displacements 32 and 50 cm³/rev. Rev Cie Téc Agr [online]. 2013, vol.22, suppl.1, pp.58-62. ISSN 2071-0054.

As part of the researches that is carried out in the Agrarian University of Havana (UNAH), in the Center of Agricultural Mechanization (CEMA), with the cooperation of the Autonomous University Chapingo (UACh), in the Department of Agricultural Mechanical Engineering (DIMA), directed to the development of the Fluid Power, they underwent evaluation two hydraulic gears pumps of the mark Caproni of Bulgarian production, with displacements or cylinder capacities of 32 and 50 cm³/rev, referring the test at two o'clock in specific and not to a statistical sample of bombs of these types. The objective of the work was to determine the technical characteristics of the referred bombs. The volumetric efficiency that is the indicator that measures the flights or flow losses, in the two bombs, went superior to 90%. The hydraulic power for the suitable pressures and frequency of nominal rotation, throws acceptable values of 11,32 kW for that of displacement 32 cm³/rev and 17,60 kW for that of displacement 50 cm³/rev. The evaluated bombs fulfill the technical characteristics presented by the maker satisfactorily.

Keywords : volumetric efficiency; hydraulic potency.
