武汉油田螺杆泵转子规格齐全「螺耐斯」

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-低，达到节能效果。

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 customers use cost will

greatly lower with effect of environmental protection&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&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.
