MAGNETIC POWER TRANSMISSION DEVICES FOR OILFIELD APPLICATIONS |
摘要 |
A method and apparatus relates to incorporating a magnetic coupling (50) for use in oilfield applications. The magnetic coupling is operatively coupled to an oilfield machine (10) to provide a controlled operational speed. The magnetic coupling may be operatively connected to a motor (48) and a drive shaft (52) where a speed of rotation of the drive shaft is controlled by an operation of the magnetic coupling (50). The drive shaft is operatively connected to the oilfield machine. |
