Abstract
The utility model relates to an oilfield pumping unit driven by a permanent magnet brushless DC motor, which adopts the permanent magnet brushless DC motor as the power. The rotating speed of the oilfield pumping unit is controlled by a controller to reach the effect that the oilfield pumping unit goes up slowly and goes down rapidly so as to realize the effect of saving electricity.
Description
Technical field:
The utility model belongs to a kind of oil-field oil pumper, especially the oil-field oil pumper that drives with permanent-magnet brushless DC electric machine.
Background technology
Domestic and the countries in the world oil production equipment of public office all is a reciprocating beam-pumping unit, all adopts alternating current generator.Wherein major part all is a constant-speed operation.According to the hole condition difference of oil well, the variation of geological conditions, the well age of oil well, oil pumper should be regulated the speed in good time, i.e. the reciprocal time, make each oil pumping amount all reach fully loaded.This kind mode can improve oil recovery efficiency, energy conservation, reduction cost for oil production.Domestic each oil field once adopted frequency converter to want to reach above control mode for over ten years, but frequency converter drives variable-frequency motor, and because of load factor is low, alternating current generator efficient is also along with reduction, and energy conservation is not too remarkable; Again because of hole condition changes frequent overload, frequency converter machine halt trouble rate is too many, so frequency converter is used not too successful on the oil field.
Summary of the invention
The utility model takes permanent-magnet brushless DC electric machine as power, controls its rotating speed by controller, reaches up slow, descending fast, realizes the effect of economize on electricity.
The technical scheme in the invention for solving the technical problem is:
Take permanent-magnet brushless DC electric machine as power.
Usefulness of the present utility model is:
1, the advantage that has conventional pumping unit.
2, speed-regulating range width, overload capacity is strong, the characteristics of suitable oil pumper, in oil recovery process, frequent overload, overvoltage, permanent-magnet brushless DC electric machine can both prevent frequent shutdown effectively.As instantaneous overload, overvoltage, system can handle transient fault with the mode of current limliting, speed limit, makes it safe operation and does not shut down.
3, saves energy.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is the system works schematic diagram
Fig. 2 is permanent-magnet brushless DC electric machine and alternating-current variable frequency motor load efficiency characteristic curve.
Among Fig. 1,1, controller, 2, permanent-magnet brushless DC electric machine.
Among Fig. 2,3, permanent-magnet brushless DC electric machine permanent magnetism load efficiency characteristic curve, 4, alternating-current variable frequency motor load efficiency characteristic curve.
The specific embodiment
Among Fig. 1, permanent-magnet brushless DC electric machine 2 replaces alternating-current variable frequency motor, and permanent-magnet brushless DC electric machine 2 reaches up slow, descending fast by controller 1 its rotating speed of control, realizes the effect of economize on electricity.
Among Fig. 2, efficient and load factor that permanent-magnet brushless DC electric machine load efficiency characteristic curve 3 and alternating-current variable frequency motor load efficiency characteristic curve 4 reflect then descend along with the decline of load, but the permanent-magnet brushless DC electric machine decline scope will be lower than alternating-current variable frequency motor, descending zero load is up fully loaded, and the alternating-current variable frequency motor average efficiency has only 48%.And permanent magnetic brushless efficient is higher 42 percentage points than alternating current generator from the efficient permanent-magnet brushless DC electric machine also more than 90%, and power factor (COS Φ) is more than 0.9.
