空心轉(zhuǎn)子優(yōu)勢：
advantages of hollow rotor:
1.空心轉(zhuǎn)子重量減輕后，與常規(guī)轉(zhuǎn)子的軸向扭力減弱，油田螺桿泵轉(zhuǎn)子，啟動扭矩降低，減速電機選型偏小，客戶使用成本大-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， 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(guān)聯(lián)，因此與同等實心轉(zhuǎn)子對比，重量減輕后，泵在運行過程中轉(zhuǎn)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.
3.泵在快速啟動和高速運轉(zhuǎn)過程中的震動明顯減小。
3. pump vibration iously decreases in the process of quick
start&high-speed operation.
4.設(shè)備運行過程中，噪音分唄大幅度降低，不會有噪音污染。
4. in the operation process of the equipment， noise decibel
is greatly lowered without noise pollution.
