Problems solved by technology

The disadvantages of workover rigs powered by diesel engines are high noise, environmental pollution, low efficiency, fuel consumption, and high cost.
In recent years, workover rigs have developed self-propelled fuel oil and electric dual-power workover rigs. The fuel engine generates power for the motor, and the motor drives the operating mechanism to work. The disadvantages are that the transmission system is complex, high in cost, fuel consumption, and pollution Environment, large system power loss, low transmission efficiency
However, the electric workover rig that completely relies on electric energy is limited by the conditions of the well site and cannot work when the power is off.

Description

technical field [0001] The invention relates to an electromechanical device for oil field exploitation, in particular to an electric workover machine with capacitor energy storage, belonging to the technical field of petroleum machinery equipment. Background technique [0002] The workover rig is a construction machine used in oil field workover operations. In the prior art, the workover rig uses a vehicle-mounted diesel engine to output power, drives the operating mechanical device to realize the lifting and lowering of oil pipes and oil rods, and drives the walking mechanical device to make the workover rig walk. The disadvantages of workover rigs powered by diesel engines are high noise, environmental pollution, low efficiency, fuel consumption and high cost. In recent years, workover rigs have developed self-propelled fuel oil and electric dual-power workover rigs. The fuel engine generates power for the motor, and the motor drives the operating mechanism to work. The d...
