Centrifugal pump mainly refers to the impeller discharge flow basically perpendicular to the axis of the pump power flow in the pump. Centrifugal pump is characterized by: high speed, small size, light weight, high efficiency, large flow, simple structure, stable performance, easy operation and maintenance; its shortcomings are: before starting the pump to be filled with liquid. Because of these characteristics, the understanding of its performance is even more important. Centrifugal pump Next, the centrifugal pump introduces several performance parameters. 1, flow rate Q (m3 / h or m3 / s) Centrifugal pump flow is the centrifugal pump liquid delivery capacity, refers to the unit of time the volume of liquid delivered by the pump; 2, head H (m) The indenter, known as the pump, refers to the energy gained by the pump of the monomer weight fluid. Pump head size depends on the pump structure (such as the size of the impeller diameter, the bending of the blade, etc., speed; 3, the efficiency of the pump in the process of conveying liquid, the shaft power is greater than the power delivered to the pipeline liquid obtained from the impeller , Because of the volume loss, hydraulic loss of mechanical losses have to consume part of the power, while the efficiency of the centrifugal pump that reflects the pump on the amount of external energy utilization; 4, shaft power N (W or kW) pump shaft power that pump shaft The value of which can be calculated according to the effective power Ne and the efficiency η of the pump. With the continuous development of China's industry, the centrifugal pump can be widely used in the fields of electricity, metallurgy, coal, building materials, etc. Because of its wider use, The study of its performance parameters becomes more necessary because the performance parameters not only reflect the characteristics of the products, but also the producers can find out the problems of the products and the directions to be improved from the performance parameters, thus we can get the performance parameters for the production And consumers are of extraordinary significance. 相关 æ–‡ç« : Centrifugal pump power formula Centrifugal pump model classification and type Daquan
