Notation of Screw Pump Selected

　　用户应根据输送介质的粘度来选择泵转速，以保证泵的NPSHr能满足实际吸入条件。一般情况按下表粗略确定：

According to the medium viscosity , select the suitable rotation speed of pump, to guarantee the NPSHr of pump is suited to the suction state. You can define it approximately:

粘度 (mm2/s)	0-400	>400-10000
转速 (r/min)	1450或2900	950或750

1. 介质粘度大于1500mm2/s，介质温度高于450℃时，请与我司技术处联系，我司将为您提供满意的服务。

2. 当泵的规格、介质粘度及相应压力流量确定之后即可查得或算出轴功率N，选配电机时，应用功率储备量M，即电机功率≥M×N，M值见下表：

Viscosity (mm2/s)	0-400	>400-10000
Speed (r/min)	1450or900	950or750

When the medium viscosity is exceed to 1500mm2/s, please contact with us. You would get a satisfactory service.

When you define the size of pump, viscosity, pressure and capacity. You can get the power of the selected pump N. The power of the motor is not less than M×N. The data of M is:

N(Kw)	N≤5	5<N≤15	5<N≤50	50<N≤100	N>100
M	1.3-1.4	1.2-1.3	1.15-1.2	1.1-1.15	1.05-1.1
