PUMPCOM: a simulation model for operating characteristics of pumping stations through combination of individual pumps.
The computer model PUMPCOM has been developed to combine pump curves series and in parallel for a variety of pumping stations using a WINDOWS environment. The model determines the performance of a pump station and of individual pumps within the station via construction of head-discharge curves, efficiency curves and curves indicating net positive suction head requeriments, graphical interface allows the user to draw the pump station layout on sreen, to view discrete data entered, and to view the fit of polynomial equations. An icon "tool box" allows the user to select an appropriate pipe fixture and place it in the layout between pumps. This allowns the pump station drawing to resemble as closely as possible the real pump station. Data tables, plots of the curves and equation coefficients, and station layout can be printed. Polynomial equations as fitted to individual pump curves and to the combined pump station curves. Cubic spline interpolations is employed to combine curves of pumps having different sizes. Performance indicators of the station and of each pump within the station are calculated over flow rate range for the entire station.
