NJ73 Bucking Unit for Sucker Rod

NJ73 (27 / 8 ″) -3 is suitable for processing and repairing of sucker rod, especially the buckle for threads with steps and normal threaded buckle hoop.The mark is subtle, and the depth is less than 0.1mm. The floating arm tong can accurately detect the buckle torque, accurately display buckle torque value from 10-300 N.M, and it is also suitable for the processing of special buckle joints.

Equipment characteristics

1.processing and repairing of sucker rod
2.Can accurately detect the buckle torque value of 10~3500 N M
3.With manual operation, fully automatic operation for selection
4.Adopt  8 " touch screen industrial control terminal for torque display, control and recording.
5.Can set operating parameters, rod body, coopling  parameters, maximum torque, minimum torque, optimal torque, maximum circles and minimum circles of buckle process.
6.Display and control buckle torque value in diagram.
7.Record, query, and print  production records in diagram and daily report mode.
8.Production process records can be transferred through U disk to any computer in the office for storage or printing.
