1. The power of the workover rig is generally high-speed diesel engine. In terms of power equipment, it is divided into single engine and dual engine. The single engine is on the car and shared under the car. The dual engine is divided into the car, and the two engines are shared under the car. On the car, one engine supplies power under the car,
2. There are two independent hydraulic systems in the workover rig, the main hydraulic system and the hydraulic power steering system.
(1) The primary effect of the main hydraulic system is the vertical release of leveling vehicles and derrick after the workover rig is in place at the well site, as well as auxiliary operations such as hydraulic winch, hydraulic cylinder collapse and hydraulic tongs.
(2) The hydraulic power steering system is used to reduce the strength of the rolling steering wheel when the vehicle is running.
3. The workover rig is generally welded with high-strength angle steel and hollow truss structure. The derrick of large-tonnage workover rig can also be welded with high-strength rectangular tubes. The workover rig can have one section and two sections according to different workover rig types. The workover rig of small-tonnage generally selects one derrick.
4. The transmission part generally uses the engine and the hydraulic mechanical gearbox to connect directly. If two engines are shared on and off the car, which requires a parallel car box, the hydraulic mechanical gearbox and the parallel car box, and the angle transmission box. Connect, then connect through the chain and the sand fishing roller or the main roller, then through the chain to the turntable angle transmission box, and the climbing chain box to the turntable. It can also be directly from the parallel car box (angle transmission box) through the transmission shaft to the climbing chain box to the turntable. Sand drum, main drum and turntable are generally controlled by pneumatic push plate clutch, or pneumatic tire clutch
5. The gas circuit system in the workover rig has the primary control effect, such as the clutch, the throttle of the engine, the gear shift of the gearbox, the control of the hydraulic pump, and the control of the throttle and brake when the workover rig is running.
