Design and Simulation of an Energy-Saving Hydraulic Oil Production System
The study on an advanced equipment of a new pumping unit is presented to satisfy the mining technology demands of large load, long stroke and low pumping speed during petroleum exploitation process. The method of using a full hydraulic system drive rather than the traditional way is adopted to overcome the disadvantages in a traditional oil production equipment such as complex mechanical structure, large volume,many transmissions, low efficiency and high manufacturing cost. In addition, the hydraulic circuit which is made up of an accumulator, a hydraulic motor and two hydraulic pumps is used to realize power recovery for energy saving. The mechanical mathematical model and the hydraulic one of a novel hydraulic oil production mechanism were established and analyzed. Good results are eventually obtained. This equipment has been the national patent.
