SNS440R54U12.1W21三螺杆泵、SN系列润滑油泵
*、确定泵的转速：（SN 系列螺杆泵的极限转速为＜6000r.p.m）
First, determine the pump speed （the speed limit: SN series screw pump for the < 6000r.p.m）
1．泵转速的选择以输送介质的粘度和泵的规格确定转速范围，一般输送高粘度介质时，
Specifications to the transmission medium viscosity and pump 1 pump speed selection range of speed, general conveying high viscosity medium,
泵应选低转速；若粘度低，相应选择高转速。
Low speed pump should be selected; if the viscosity is low, the corresponding selection of high speed.
对于大规格的泵（主杆外径∮60mm 以上）
The specifications of the pump （above the main rod diameter, 60mm）
介质粘度γ＞20°E 时，转速以970rpm 或720rpm 为宜。
Medium viscosity γ > 20 ° E, speed to 970rpm or 720rpm is appropriate.
若γ＞80°E 如粘胶液，转速可选n=200~500rpm
If gamma > 80 ° E such as viscose, speed optional n=200~500rpm
对于小规格的泵（主杆外径∮60mm 以下）：
For small size pump （main rod diameter, below 60mm）:
γ＞20°E 时，n 选1450rpm 或970rpm.
Gamma > 20 ° E, n 1450rpm or 970rpm.
γ＞80°E 时，n 选300~600rpm。
Gamma > 80 ° E, n 300~600rpm.
2．由于泵的转速愈高摩擦功率愈高，泵的磨损越大，寿命越短，如果输送介质的润滑
2 because the pump speed is higher friction power is higher, the greater the pump wear,short life, if the lubrication delivery medium
性较差，或含有微量杂质，应选较低转速，使泵保持较长的使用寿命。*n＜1450rpm
Poor, or contain trace impurities, should choose the low speed, long service life of the pump.Recommended n < 1450rpm
第二、结构形式的选择
Second, the choice of structure
结构的选择可根据泵的运行环境和安装环境，选择合适的安装形式并遵循以下的原则：
Structure selection according to the running environment of pump and the installation environment, choose to install the appropriate form and follow the following principles:
1． 输送润滑性油类，且温度T＜80℃时，选择内置轴承结构的泵。
A 1 conveying lubricating oil, and the temperature of T < 80 ℃, the choice of built-in bearingstructure of pump.
2． 输送润滑性较差，或温度T＞80℃时，选择外置轴承结构的泵。
2 delivery of poor lubrication, or temperature T > 80 ℃, select the external bearing structure of pump.
3． 输送流动性差，粘度高的介质或对所输送介质进行加热或保温时，选双层加热泵体
3 the transport mobility is poor, high viscosity of medium or to transfer medium heating or insulation, choose double heating pump body
结构的泵。
Structure of pump.
4． 输送高温介质时，应选择耐高温的材料制成的泵或局部冷却的泵。
The 4 conveying high temperature medium, should choose the high temperature resistant material made of pump or local cooling pump.
5． 关于泵的吸入能力可查阅样本。

第五、配套电机的选配
Option fifth, matching motor
泵的型号选定后，根据样本数据，可查到泵的轴功率N，该轴功率再加上一定的功率储
The pump model is selected, based on sample data, can be found in the shaft power Npump, the shaft power coupled with a power storage
备后，作为选配电机的依据，一般电机功率Nm 不小于泵轴功率N 乘以功率储备系数K 所
