 ●SN 系列螺杆泵选型步骤
1. 首先应根据油品的粘度选择适当的泵转速，以保证泵的 NPSH 能满足用户的实际吸入条件。
2. 介质粘度 υ＞ 10000mm 2 /s 时请与我公司，我公司帮助用户选泵。
3. 从性能表中选定泵的规格及相应粘度下的压力流量后， 可查到泵的轴功率 N ，
   该轴功率再加上一定的功率储备后，作为选配电机的依据，一般电机功率 N m
   不小于泵轴功率 N 乘以功率储备系数 K 所得的值即： N m ≥ K · N 。 K 值由下表查得。
N（KW） K
N ≤ 5 1.25
5 ＜ N ≤ 10 1.2
10 ＜ N ≤ 50 1.15
N ＞ 50 1.1
