Pump common parameters pumps are commonly used in our daily use of representative meaning, especially used for the first time we have a lot of questions don't know the meaning of parameter represents the actual flow rate (m3 / h or L/s) : refers to the number of pump conveying fluid, flow expressed in the letter Q head (m) : refers to the unit weight of the fluid through the pump can always head (level), head with letter h said power (KW) : refers to the output power of pump, and also is the power of the motor to the pump shaft function P saidEfficiency: refers to the percentage ratio of pump output power Pe to input power P, and reflects the shaft power utilization rate speed (unit r/min) of the pump in the process of transfer volume: refers to the pump blade revolution per minute, which is represented by n as an important factor affecting pump performance. When the speed changes, the performance of the pump will change.

流量 (单位 m3/h或L/s)：是指单位时间内泵输送流体的数量，流量用字母Q表示。

扬程(单位 m)：是指单位重量的流体通过泵获得的总能头（高度），扬程用字母H表示。

功率（单位 KW）：是指泵的输出功率，也就是电机传给泵轴上的功率，功用字母P表示。

效率：是指泵的输出功率Pe与输入功率P之比的百分数，反应泵在传递量过程中轴功率利用率。

转速（单位 r/min）：是指泵叶每分钟的转数，用n表示。它是影响泵性能的一个重要因素，当转速变化时，水泵的性能将发生变化。
