Title: Association of pumps in parallel: different machines Description: The learning object shows how to determine the curve resulting from associating pumps in parallel with different machines Pérez Sánchez, M.; López Jiménez, PA. (2019). Association of pumps in parallel: different machines. http://hdl.handle.net/10251/116104 Automatic description: In this video, the professor of the hydraulic engineering and environment department of a polytechnic university offers an explanation on the association of pumps in parallel with different machines. It explains how to know the curves resulting from this association, divided into four parts: an introduction, the formulation of equations, a case study and conclusions. First, the need to associate pumps in parallel is justified when a single one cannot cover the required flow rate, followed by the description of the equations that govern this type of association. A distinction is made between identical and different pumps, and the methodology for determining the joint curve is provided, which involves identifying three operating points and solving a system of equations to find a polynomial that represents them. The practical case shows how to obtain the operating point and efficiency curves for two pumps with different flow-head capacities. Finally, it is concluded that the pumps work at different flow rates and, therefore, have different efficiencies when they are associated in parallel.
