Oct 21, 2020 · As pressure increases, the flow decreases moving your performance point to the left of the curve. As pressure decreases, the performance point runs out to the right of the curve and flow increases. When looking at curves for a new application, there are many factors to consider.sp.info Performance curves Article about performance curves by (engineering) Graphical representations showing the abilities of rotating equipment at various operating conditions; for example, the performance curve for a compressor would include rotor speed for various intake and outlet pressures versus gas flow rate adjusted for sp.info Centrifugal Pump Curves - 4 Types of Performance CurvesEfficiency Curve. Power / Energy Curve. NPSHR curve. Pump Family Curve. Head Vs. Flow Curve (H-Q Curve) The first curve under pump performance characteristic is the head Vs. flow rate curve. It is also known as a pressure vs. quantity curve. To draw this curve head is plotted on Y-axis, and flow is plotted on X-axis.sp.info Sulzer Select SulzerSulzer Select allows customers to make quick, accurate pump selections and to produce PDF output of the performance curve and data. Pump selections can be made by inputting specific operating conditions or by selecting specific pump sizes. Sulzer Select is a powerful tool but cannot include all hydraulics that Sulzer can offer.

Sep 24, 2018 · Pump curves are drawn showing the performance of the Rated Impeller Diameter. Some curves are drawn to show the performance of several Impeller Diameters from the Maximum Impeller to the Minimum Impeller. Centrifugal pump impellers can be machined to larger or smaller diameters to alter the performance to best match the application.sp.info Performance curves for single activities – RUNALYZEJan 06, 2021 · Performance curves for single activities. 6. January 2021, Posted in Features. With the latest update, Runalyze can now display power, pace and heart rate performance graphs for individual activities. These graphs show the best or maximum performance for all possible time periods – from one second to the entire activity duration.sp.info Using Performance Curves as a Service ToolThe term “performance curve” comes from the method which has been used for generations by plotting compressor performance in a graphical format and relating it to saturated suction temperature vs. saturated discharge temperature. Typically the plots include curves for capacity, power input and amperage at a sp.info Performance curves - The BLUEline Rotary Lobe Pump Pump performance curves provide information about the efficiency of a pump. The flow rates of Börger rotary lobe pumps remain virtually constant even in case of increasing pressures. In order to have a look at the individual pump sizes, please press +.
