Automatización de la adquisición de datos en tiempo real del banco de pruebas de la bomba de ariete hidráulico del laboratorio de turbomaquinaria hidráulica de la Facultad de Mecánica de la ESPOCH.

Abstract

The automation of the hydraulic RAM pump test-bed data acquisition, aims to get a bank functional, can be manipulated and reliable that allows people to develop knowledge and skills of the phenomenon of wáter hammer with tables of results and graphs of wasted and pumped flow, efficiency, power and duration of the cycle, all depending on the height of discharge. The study began with the measurement of the variations of pressure and flow, values determinants for selection and purchase of transmitters pressure SITRANS P220 and palette type flow sensors OMEGA FP-5600; in addition, was developed a card-converting a frequency signal to voltaje with integrated LM331 , the data acquisition was performed with the card DAQ NI USB-6009 and software LabVIEW in which was introduced the equations for each sensor obtained in the calibration. Trials with different opening of the value to the entry of pump of RAM with different races and weights of valve of momentum were, and all of the above variables were recorded by LabVIEW software which generates a report in Excel. Reports noted that as the height of discharge and waste flow increase, decrease the pumped flow, efficiency, power and duration of the cycle time. At the end of the work it was found that water hammer in pipeline systems not only means a serious problem; but that can be used by these pumps to lift water 24 hours a day, 365 days of the year without any energy input, becoming an becoming an ecological pump that helps the sustainable development of humanity.
