• The operating point of a centrifugal pump, also called its duty point, is given by the intersection of the pump characteristic curve with the system curve. • The flow rate Q and the developed head H are both determined by the intersection. • To change the operating point either the system curve or the pump curve must be changed. Jun 26,  · Knowing how to read a centrifugal pump curve is essential to the health of your system. Running too far out on the curve, or too far back, can cause damage to the pump, excessive energy consumption, and overall poor performance. Jordan, an Application Engineer at Crane Engineering, explains how to read a centrifugal pump curve in the video below. reader with a basic understanding of the principles of the centrifugal pump and pump terminology. The centrifugal pump is the most used pump type in the world. The principle is simple, well-described and thoroughly tested, and the pump is robust, ef-fective and relatively inexpensive to produce. There is a wide range of vari-ations based on the.

Tags: Base camp garmin deutsch, Stcc the game 2, Understanding Centrifugal Pump Curves When selecting a centrifugal pump, one should match the performance of the pump to that needed by the system. To do that, an engineer would refer to a pumps composite curve. A typical composite curve includes the pump performance curves, horsepower curves and NPSH required. Characteristic curves of centrifugal pump Fratišek Hovorka, Michal Kordač I Basic relations and definitions Centrifugal pumps are mai used for transport of liquids. Knowledge of characteristic nly curves of centrifugal pumps provides us with information about operating efficiency and can help us with selection of a suitable pump. reader with a basic understanding of the principles of the centrifugal pump and pump terminology.

Jordan, an Application Engineer at Crane Engineering, explains how to read a centrifugal pump curve in the video below. Introduction to Pump Curves The pump develops energy called discharge pressure or total dynamic head (tdh). This pressure is expressed in units of measure called pounds per square inch (psi) or feet of head(ft.). NOTE: 1 psi will push a col-umn of water up a pipe a distance of ’. A perfor-mance curve is used to determine which pump best. • The operating point of a centrifugal pump, also called its duty point, is given by the intersection of the pump characteristic curve with the system curve. • The flow rate Q and the developed head H are both determined by the intersection. • To change the operating point either the system curve or the pump curve must be changed. Centrifugal Pump Characteristic Curve For an Operations Engineer who is working in a Chemical Process industry or a Process engineer who is involved in Hydraulic calculations understanding the Centrifugal Pump Performance Curve is an important aspect. Components of Centrifugal pump performance curve 1. Head Vs Flow Curve: H-Q Curve 2. Reading and understanding centrifugal pump curves is key to proper pump selection, and to their reliable and efficient operation. This Tech Brief examines how pump curves can provide data about a pump’s abili-ty to produce flow against certain head, shows how . For the normal operating range of centrifugal pumps (n, Q and H all positive), it is sufficient to plot the characteristic curve in the first quadrant of the H/Q coordinate system.
