A New Energy Saving Method For Surface Oil Recovery Equipment

The conventional pumping-unit is still the main oil recovery equipment in the oil field at present because of simple structure ,convenient operation and mainterance,long use life.But it runs unevenly and consumes much,which cann't satisfy the request of energy-saving .So ,in this paper ,on opinion of the fact and idea of litter expenses and faster result, the better the fewer altered parts,and the distinct energy-saving impact on the condition that the pumping working do not changed. A new method of energy-saving is presented.The major parameters of conventional pumping-unit are optimized ,and then ,an equipment is fixed on the shaft of motor to add up the moment of inertia,which can adjust the velocity wave by means of storing and releasing energy,and the torque wave is evener,the peak is cut down,therefore the asynchronous motor matches with the pumping working,and motor working condition is improved.The aim of energy-saving is realized. In the paper ,the energy-saving principle is analyzed firstly.A mathematical model is established and the aim function and restrain factors are listed.Optimal process is compiled by means of compound method to work out the result,Kinematic peromance and dynamical performance are analyzed,the curves of performance are plotted.The structure of energy-saving is designed.The maximal profit and loss of equivalent dynamics model is worked out according to the law of conservation of energy, and then the moment of inertia of the equipment and the structural parameters are aquired.At last the conclution is gained by comparing the relative parameters and the curve of performance. This new method is designed in view of practical condition at spot.Excellent energy-saving effect and economic benefit will be obtained.
