摘要

The pipe isolation tool plays an important role in ensuring the safety of transporting oil and gas pipelines. But the life of the intelligent pipe isolation tool is also affected by the service life of the battery. Therefore, this paper based on the working principle of the pipe isolation tool and the actual working environment to improve the original hydraulic system. The accumulator absorbs the kinetic energy of the pipe isolation tool in the pipeline movement. Then the energy in the process of plugging would be released to complete the closure of plugging and save energy. First, calculate the parameters of each part of the device. Then based on the three basic equations of fluid mechanics and the calculated parameters, the mathematical model of the system is established to obtain the transfer function. Finally, the PID controller is added to improve the system performance. Simulation results verify that both energy-saving and position tracking objectives are satisfied.
