A pump curve is a graphical representation of the performance characteristics of a pump. A pump curve provides a wealth of information regarding the performance capabilities of a pump. Information is plotted on an x-y graph where the x-axis is measured in units of flow and the y-axis is measured in units of head, power, and NPSHr.
2022年5月26日 · A pump curve shows the two performance factors on the X,Y axis so you can see the volume of fluids a pump can transfer under various pressure conditions. This pump curve explanation also discusses variables such as: RPM. Impeller size, as they related to pump performance. Power. Efficiency.
2018年2月19日 · A pump curve denotes flow on the x-axis (horizontal) and head pressure on the y-axis (vertical). The curve begins at the point of zero flow, or shutoff head, and gradually descends until it reaches the pump runout point or maximum flow rate.
The performance curves for a centrifugal pump are shown in figure 1. Head, power consumption, eficiency and NPSH are shown as a func-tion of the flow. Normally, pump curves in data booklets only cover the pump part. Because of this, power consumption, the P2-value, listed in data booklets, only covers power going into the pump (see figure 1).
2020年4月25日 · Basic Pump Curve The basic pump curve looks like this. Pump Curve Example They do get more complicated and look something like this. Don’t worry we’re going to go through them step by step and start from the basics. Pump Curve Example Each type of
Pump curves. The efficiency curve shows the η (efficiency) of the pump. Efficiency is measured in %. All pumps have a ‘best point’ (ηmax), indicating where the pump is working most efficiently. The efficiency of the pump depends on the pump size and the quality of the construction/production.
2018年9月24日 · By PumpWorks Engineering Team / September 24, 2018. Centrifugal Pump curves show 8 important factors that are critical in selecting the right pump for your application. These factors are: Flow, Head, Impeller Trim Diameter, Efficiency, Power, NPSHR, MCSF (Minimum Continuous Stable Flow) and RPM.
