Dimensionamiento y selección de amortiguadores de pulsaciones para bombas reciprocantes utilizadas en la extracción de crudo en el sistema power oil

Abstract

The objetive of this Project was to carry out the sizing and selection of pulsation dampers in reciprocating pumps used in the extraction of crude oil in the power oil system. It Will seek to develop a spreadsheet in Matlab for the sizing and selection of the three types of pulsation dampers (PE, CT and ZM), which can be installed in the referential system (Lago Agrio #23), which uses a reciprocating pump National triplex. The damping units were designed, based on the considerations of the standard of the American Society of Mechanical Engineers (ASME) VIII division 1 of 2019, with this the modeling was carried out in SolidWorks. Finally, the operation of the devices was validated according to finite elements in ANSYS, this procedure served to verify if the thicknesses and dimensions abtained are correct and can withstand the operating conditions. The calculated theoretical values of Von Mises stress, deformation, safety factor and fatigue are very close to the values obtained from the ansys analysis and from the analytics, being adequate for the operating requirements with a percentage error within 10% in the results, it means, the data is validated and the design of the pulsation dampers are considered safe and most likely not to fail.This is due to the correct selection of the thicknesses between 0.28 and 1.5 inches respectively, which correspond to the five units selected for the design. To conclude the design of the bodies and other components have sufficient resistance in the designed load conditions, capable of withstanding an overpressure in its operation. It is recommended that if the pumping system exceeds 15 psi, these pulse attenuation devices should be installed.
