　解：通常把表示主要性能参数之间关系的曲线称为离心泵的性能曲线或特性曲线，实质上，离心泵性能曲线是液体在泵内运动规律的外部表现形式，通过实测求得。特性曲线包括：流量-扬程曲线(Q-H)，流量-效率曲线(Q-η)，流量-功率曲线(Q-N)，流量-汽蚀余量曲线(Q-(NPSH)r)，性能曲线作用是泵的任意的流量点，都可以在曲线上找出一组与其相对的扬程，功率，效率和汽蚀余量值，这一组参数称为工作状态，简称工况或工况点，离心泵最高效率点的工况称为最佳工况点，最佳工况点一般为设计工况点。一般离心泵的额定参数即设计工况点和最佳工况点相重合或很接近。在实践选效率区间运行，即节能，又能保证泵正常工作，因此了解泵的性能参数相当重要。;DF280-65*8;DF280-65*8;DF280-65*8;DF280-65*8;DF280-65*8DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-65*8_DF280-​
