Operating principle:
First, present invention utilizes the characteristic of electric current, achieve the automatic reverse of oil pumper.
Moreover starting torque required for the present invention is little.Required starting torque size during startup is also determine required consumed power size.Its motion process is that upstroke bottom dead centre accelerates to start, and---reduce speed now motion to upstroke---to down stroke, starting the motion of accelerated motion speed---, and reduce speed now motion to upstroke, Zhou Erfu, gives longer acceleration time to upper bottom dead centre.
By the adjustment of frequency converter and PLC control system, when upstroke starts, what just started to start is very slow, now to be dragged primer acceleration also very little, the fluctuation of electric current is also very little, the quickening of the power frequency controlled along with frequency converter and PLC control system; Speed constantly strengthens, and now motor is a stable loading procedure.Now single from motor aspect, eliminate part by the energy ezpenditure dragged needed for the conversion of primer momentum.If allow motor locate at the uniform velocity under state always, also will allow will be very large by the power of dragging needed for primer momentum change:
F-Mg＝MV/t
M weight quality
V weight speed
F weight acts on power on lifting rope
G acceleration of gravity
Required time when t reaches a constant speed
Inevitable electric current can be very large, and motor in-fighting must increase.Acceleration time must be lengthened to reduce this in-fighting.Must slow down in a segment distance of before top dead center; Otherwise, oil pumper can not be stopped when upper dead center position to drag primer and to move upward; Now along with frequency converter and PLC control system control the deceleration of power frequency; Speed constantly declines, and now motor is a stabilization process.During down stroke, counterweight part weight after oil pumper, the weight difference of what oil pumper was carried is rear counterweight and front end.That is motor is repeating the action of oil pumper upstroke.Electric current needed for it reduces, so it is energy-conservation on the one hand for this.
Another energy-conservation reason is: cylinder 13 is wound around suspender belt and realizes reducing (as Fig. 4-Fig. 7).During upstroke, weighting distribution wheel has been wrapped over suspender belt, and lifting wheel suspender belt is all released, cause wheel footpath now not, rear counterweight is large to the arm of force of bottom main shaft effect, and the arm of force of front end is less.Front and back to the moment that main shaft produces are:

D suspender belt thickness
The moment that then now rear counterweight produces at this moment is maximum, reduces the moment of torsion that motor will export, reduces motor institute subfam. Spiraeoideae.While rising, the arm of force of rear portion counterweight is in reduction, and the front end arm of force is in increase, and oil pumper is simultaneously also in unloading.Maximum to front end arm of force during top dead-centre, the rear end arm of force is minimum; Be repeated the operating mode of top dead-centre conversely.Upper bottom dead centre it be reduced electric current needed for motor, so it is energy-conservation.
During work, motor 10 drives cylinder 13 to roll, thus makes whole oil pumper work.When needs oil pumper is stepped down, employing is turned over and steps down, allow belt and semi girder fix, start oil pumper, can pull on semi girder and turn over, thus reach the object of stepping down.Change the length of electric current commutating period under controlling equal power frequency by frequency converter and PLC control system, change the stroke (equal jig frequency) of oil pumper.Change power frequency controlled the length of equal electric current commutating period by frequency converter and PLC control system under, the jig frequency (equal stroke) of oil pumper can be changed.
Embodiment two: the present embodiment is substantially identical with embodiment one, and something in common does not repeat, and difference is: pylon assembly is monolithic construction, without dismounting, simplifies construction sequence, is applicable to low pylon occasion.
The concrete structure changing the concrete structure of power assembly, change the concrete structure of lubricating box, change cylinder, and the concrete structure changing semi girder assembly can form multiple embodiment, is common change of the present invention, does not describe in detail one by one at this.
