Long life Corrosion Preventive Mud Motor Rotor for Downhole Drillling Motor
The power section is the most important part of down hole motor. We define a power section by its outer tube diameter,rotor/stator lobe configuration and number of stages.
We can provides motor size from 2 7/8" to 11 1/4". Normally, the motor can output more torque and power as the tube size increase.
The rotor and stator are designed as helical elements with a major and minor diameter. The lobe is the curved spiral shape formed by the difference in the major and minor dimension.
Our supply chain of steel manufacturers with excellent national and international reputations allows us to bring highly durable motors to market.
Our careful selection of special material grades for our motors provides the needed performance.We use the world's most advanced continuous injection equipment imported from Germany for manufacturing.
Optimize processing technology:
Professional measurement technology with an accuracy of ± 0.02 mm;
Fully digital processing equipment ensures processing accuracy;
Application effect:
Smooth operation and higher power conversion efficiency;
Increase torque by 25%~50% with the same level of numbers;
Increase lifespan by 50%~100%;
