Electric Workover Rig

Electric workover rig is a new-type, high-efficiency, energy-saving, environmental-protection workover equipment, which is made up of the second-class chassis, voltage transformer, power distribution cabinet, freguency conversion control cabinet, AC freauency conversion motor, anale gear box, drawworks assembly, mast assembly, traveling system, electric lubricating system, air compression system, hydraulic and pneumatic control system and its accessories, etc. The welsite power is used as its power source when it works. The power is output through power distribution box (1 140V or 380V of the pumping unit in well site, changed into 380V AC after passing through voltage transformer, then put into power distribution box and AC frequency conversion cabinet, then put into the main motor after passing through AC frequency conversion controller. The main motor drives the angle gear box and the drawworks to do the trip up and down tubing operation.
