油田螺杆泵转子-武汉螺耐斯

3.泵在快速启动和高速运转过程中的震动明显减小。

3. Pump vibration iously decreases in the process of quick

start and high-speed operation.

4.设备运行过程中，噪音分呗大幅度降低，不会有噪音污染。

4. In the operation process of the equipment， noise decibel

is greatly lowered without noise pollution.

空心转子优势：

Advantages of hollow rotor:

1.空心转子重量减轻后，与常规转子的轴向扭力减弱，启动扭矩降低，减速电机选型偏小，客户使用成本大大降低，达到环保节能效果。

1. After the weight of the hollow rotor decreases， the axial

torsion of conventional rotor will recede， break-out torque will lower， gear

motor type will be relatively small， as well as customer's use cost will

greatly lower with effect of environmental protection and energy saving

obtained.

2.因摩擦力与重量有密切关联，因此与同等实心转子对比，重量减轻后，泵在运行过程中转子摩擦力减弱，使用寿命同比增大。

2. Because the force of friction is closely related to

weight， the force of friction of the rotor lowers and service life increases on

a year-on-year basis in the operation process of the pump after the weight1

decreases in comparison to the equivalent solid rotor.
