油田螺桿泵轉子-螺耐斯

空心轉子優(yōu)勢：

advantages of hollow rotor:

1.空心轉子重量減輕后，與常規(guī)轉子的軸向扭力減弱，啟動扭矩降低，減速電機選型偏小，客戶使用成本---降低，達到節(jié)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，油田螺桿泵轉子， 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.因摩擦力與重量有密切關聯(lián)，因此與同等實心轉子對比，重量減輕后，泵在運行過程中轉子摩擦力減弱，使用壽命同比增大。

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.
