Feasibility of applying raceway reducer on screw pump system

The feasibility of applying raceway reducer on screw pump system is investigated. And it is indicated that the raceway reducer is very suitable for the drive of the screw pump. By using this kind of reducer, low and constant numberof turns and large torque of screw pump can be obtained. The design feature and operating principle and key techniques of the raceway reducer are described. The result of test and analysis proves the raceway reducer has been made with desired technical parameters. Practice shows that the raceway reducer can be used for screw pump system in oil production.
