Key Techniques Of Pumping Unit Energy Saving Recnstruction

With the rapid development of economy, the oil industry is becoming more and more important, the pumping unit is one of the most common petroleum mining machinery applications. In various types of pumping machine, beam pumping unit is important, it is a kind of lifting equipment of oil used most widely, accounting for about 95% of the oil well artificial lift equipment. The oil pumping machine as the main production equipment of oil field, the drive motor power consumption accounted for a large proportion of the total oil consumption, the oil consumption accounted for about 40% of the total electricity use, and the overall efficiency is low, resulting in a large number of waste oil power, increase the cost of oil. So, how to reduce energy loss and improve the mechanical efficiency of pumping unit, improve the degree of automation of the pumping unit, is an important topic that we need to study for a long time.The key technology for pumping unit energy saving in this paper, combined with the special formation of Changqing Oilfield in Xinjiang third pumping plant organic development of beam pumping unit support, research and development of a moderate price, obvious energy saving effect, can improve the power factor of the power grid and improve the power factor of the motor, oil pump reducing energy the work of the pumping unit in the process of loss of equipment, so as to achieve the purpose of energy conservation. This paper studies the existing domestic and foreign development status of oil pumping machine energy-saving technology, energy-saving principle and the existing technical structure, motor oil pumping machine itself, to study the relationship between smoking, balance and energy saving of oil machine, analyzes the reasons and ways of saving energy consumption of conventional pumping unit through the analysis cm safety of Changqing Oilfield Block 201 pumping oil machine actual working condition, the comparative study of the effect of energy saving technology and SCR inverter PWM inverter motor the traditional variable flow system. This paper through the research of energy-saving baking machine, have different characteristics for different types of motor, to use a variety of production environment, and formation. And an increase in the frequency conversion control device in AC motor, to realize the intelligent control, the application of variable frequency technology to realize the automation of the production process, and has obvious energy-saving effectThe conclusions are as follows: the use of inverter type PWM converter, not only solves the problem of the motor power down, and solve the problem of the big car Mara, the power factor is improved. The pumping unit application of converter, improve work efficiency, increase oil production, and save energy, protect motor and equipment. In today’s increasingly tense energy converter, the huge function in the pumping unit energy saving from the opposite...
