Realization Of A Smart Power-saving Controller For Oil Pump Unit

As crude oil is extracted continuously in oil field, there are more and more low yield oil wells in old oil field, and the problem of void pumping is becoming more serious. Rational control of the pump's work and rest time can save electricity, prevent the break of beam hanger caused by beating liquid, and reduce attrition of the pump.Rational control of the pump's work and rest time is the key to solve the problem of void pumping. This essay gives theoretical analysis and cost comparison of every detective method, considers power detection as the most effective method, and puts forward several ways of power consumption and effectiveness power consumption at the same time. The designed electricity saving controller integrate all the above four methods, and it can work with different methods by switch between automatic and manual to broaden its accommodation.To achieve rational control, this intelligent electricity saving controller adopts the AVR(90S8535) chip which is produced by Atmel company, and has the related software and hardware design of the chip. The Atmel company, and has the related software and hardware design of the chip. The paper proposes the actual test effect of this electricity saving controller when used on the spot.
