Description
Technical field
The utility model relates to the oil pump energy-saving technical field, is specifically related to a kind of intelligent oil pumping machine energy-saving controller.
Background technology
In the oil exploitation process, for the startup that guarantees oil pumper requires and in operation enough overload capacity arranged the time, the installed power of motor is bigger usually; Its oil pumping jig frequency (unit interval in oil pumping number of times) is higher, and during electric motor normal working all with light running, therefore cause the load of oil pumper and motor to mate unreasonable; Oil well is aging gradually in addition, and fluid supply capacity constantly descends, and the oil pumping jig frequency is constant; " pump is empty " and " dry tap " situation of various degrees in the work of oil pumper underloading; The phenomenon of this " low load with strong power " has not only caused the reduction of oil pumper power factor, and the oil pumping backlash increases, and wastes a large amount of electric energy; And the pumping unit loss is strengthened, maintenance cost increases.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of intelligent oil pumping machine energy-saving controller is provided.
Its technical scheme is: comprise level sensor, flow sensor, central processing unit and frequency converter, level sensor is arranged in the oil well, and flow sensor is installed on the oil well flow line.The output terminal of said level sensor is connected with the input end of first amplification and rectification circuit; The output terminal of first amplification and rectification circuit is connected with an input end of central processing unit; The output terminal of said flow sensor is connected with the input end of second amplification and rectification circuit; The output terminal of second amplification and rectification circuit is connected with another input end of central processing unit, and the output terminal of central processing unit is connected with the control end of frequency converter, and the output terminal of frequency converter is connected with pumping-unit motor.
Wherein, said central processing unit is single chip circuit or Programmable Logic Controller.
The utility model has following advantage compared with prior art: 1, simple in structure, easy to use; 2, predict the real work parameter of oil well automatically, when oil pumper is in relative underloading, make oil pumper reduce jig frequency speed automatically, when oil pumper is in relative weight, make oil pumper improve jig frequency speed automatically; 3, solve that the oil field sky is taken out, inefficient, problem such as flog a dead horse, reach the mechanical wear that reduces oil pumper and the purpose of energy savings.
Description of drawings
Fig. 1 is the circuit structure diagram of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of intelligent oil pumping machine energy-saving controller comprises level sensor 1, flow sensor 2, central processing unit 5 and frequency converter 6, and level sensor 1 is arranged in the oil well, and flow sensor 2 is installed on the oil well flow line.The output terminal of said level sensor 1 is connected with the input end of first amplification and rectification circuit 3; The output terminal of first amplification and rectification circuit 3 is connected with an input end of central processing unit 5; The output terminal of said flow sensor 2 is connected with the input end of second amplification and rectification circuit 4; The output terminal of second amplification and rectification circuit 4 is connected with another input end of central processing unit 5; The output terminal of central processing unit 5 is connected with the control end of frequency converter 6, and the output terminal of frequency converter 6 is connected with pumping-unit motor 7.Said central processing unit 5 is single chip circuit or Programmable Logic Controller.
During operation; The signal of level sensor 1 and flow sensor 2 flows to central processing unit 5 and carries out computing through behind first amplification and rectification circuit 3 and second amplification and rectification circuit 4, and the low and oily delivery rate of liquid level hour in oil well; Central processing unit 5 is that control of conversion device 6 reduces frequency; Thereby the rotating speed of control pumping-unit motor 7 reduces, otherwise then improves the rotating speed of pumping-unit motor 7, reaches the mechanical wear of reduction oil pumper and the purpose of energy savings.
