Introduction
The electromagnetic eddy current brake is a new auxiliary brake suitable for petroleum drilling rig on onshore and offshore, which is take advantage of electromagnetic induction principle and carrying out brake without wearing, having the features of large torque, no consumable accessories, operating longer period, simple operation and maintenance. Using the eddy current brake can reduce break system to wear greatly, prolonging operating period of brake hub, decreasing labor strength for drilling crew, basically without operating main brake during run in hole, brake moment can be regulated just by changing exciting current to control speed of drill pipe running in. 75 per cent of maximum torque can be got when the rotary speed is reduced to 50 r/m, which can fully satisfy with requirements of tripping in with heavy load. The brake has passed performance test which is carried out by Products Mass Monitoring Center on petroleum drilling and production, refining equipment of State, also has obtained certificate of application in location, it has excellent performances , getting to the domestic advanced level, having passed identification about province stage, widely having used and popularized in every oil field of state.
