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 (單位 m3/h或L/s)：是指單位時(shí)間內泵輸送流體的數量，流量用字母Q表示。

揚程(單位 m)：是指單位重量的流體通過(guò)泵獲得的總能頭（高度），揚程用字母H表示。

功率（單位 KW）：是指泵的輸出功率，也就是電機傳給泵軸上的功率，功用字母P表示。

效率：是指泵的輸出功率Pe與輸入功率P之比的百分數，反應泵在傳遞量過(guò)程中軸功率利用率。

轉速（單位 r/min）：是指泵葉每分鐘的轉數，用n表示。它是影響泵性能的一個(gè)重要因素，當轉速變化時(shí)，水泵的性能將發(fā)生變化。
