Super Capacitor Energy Storing Dual-Power Workover Rig

Super capacitor energy storing dual-power workover rig mainly consists of Diesel engine power unit which is made up of Diesel engine and Hydraulic transmission box, Electric power unit which is made up of Frequency conversion motor and Mechanical transmission box, Transfer case, Angle gear box, Drawworks, Mast assembly, Super capacitor energy storing and control system, Hydraulic and Pneumatic control system, Voltage transformer, Power connection box, MCC control cabinet, Freguency conversion cabinet, Electric air compressor, Electric hydraulic pump station etc.

The workover rig can use the power of pumping unit (70kW) in well site to do the workover service (less than 90t).

The power of Diesel engine is used for the heayy load workover iob of workover rig, such as running and jam release etc. The power of Freguency conversion motor is used for the normal trip-up and down operation.
