用户确认泵出口去丁醇处理装置的最大扬程是合适的。
Ctc maximum head is suitable for pump discharge to butanol handling facility.
叶片数对扬程切割指数的影响最大，对流量切割指数影响较小，对轴功率和效率切割指数影响最小。
The effect of the number of blades on the head exponent is the largest, on flow rate exponent is lager and on power, efficiency exponents are minimal.
结果表明：迷宫螺旋泵扬程系数最大值随流量的增大而减小；
The analysis results show that the maximal value of the pump head coefficient declines when the flow rate increases;
