Description
Technical field
The present invention is a kind of Online Monitoring Control device calculating for the beam pumping unit degree of balance and automatically adjusting.Special
It not to complete the degree of balance optimum optimization to the beam pumping unit installing balance regulator additional and automatic feedback regulation.
Background technology
At present, beam pumping unit exist based on degree of balance energy saving research exist artificial balancing difficulty, the degree of balance up to standard
The problems such as rate is low, intelligentized control method level is low.Present stage, in oil pumper management, current balance type rate is usually used in judging that oil pumper is
No balance.In fact, current method balance of well pumping unit method of testing has very big defect, the degree of accuracy theoretical in practical operation
Poor, there is false equilibrium problem.Balance of well pumping unit degree is improved by profit in this way, and effect is poor, and occurs taking out
The situation that oil machine energy consumption increases.At present, " the power-balance method " and " indicator card balancing method " that be related to can not solve relevant well
The problem of oil pump energy-saving.
Content of the invention
It is an object of the invention to provide a kind of beam pumping unit degree of balance that may be used for oil field practice application to calculate
And adjusting means.Final realization realizes automatic feedback control to beam pumping unit so that it is run on maximum energy-saving state.
For realizing this purpose, the present invention proposes based on " extreme power " on the basis of original calculated equilibrium degree method
Degree of balance control method.The method by detection input power in a jig frequency for the oil pumper, by it in certain interval pole
State during little value regards as desirable balance state.For a concrete oil pumper, automatically examined by electrical parameters detection part
Survey the mean power of the complete stroke of record one, control balance weight simultaneously and regulate specific step value to a direction.One
After section special time, treat that oil pumper is stable, retest, continues adjustment block simultaneously.Repeatedly obtain after measurement and regulation
To oil pumper mean power time history plot.Determine that on curve, its minimum point in certain interval of power is optimal
Poised state.
Do not need the parameters such as Pumping Unit based on the method for " extreme power ", oil pumper type is not limited, be suitable for
On-the-spot application.It is characterized in that having abandoned the original direct calculation method to the degree of balance such as " current method ", " power method ", it is right to have broken away from
The dependence that oil pumper up-down stroke operational factor is worth most, directly uses oil pumper input power value to judge degree of balance regulation shape
State, control object is clear and definite, it is achieved that self feed back controls.
Device is divided into three parts, oil pumper parameter Real-time Collection part, degree of balance calculating section, output control part.
First the obliquity sensor module being fixed on oil pumper is gathered oil pumper and run upper bottom dead centre, determine the stroke letter of oil pumper
Breath；Then the information such as oil pumper input three-phase voltage, electric current, power are gathered by three phase power acquisition module, in conjunction with stroke letter
Breath is completed the judgement to oil pumper running status and calculating by degree of balance calculating section；Finally, by result of calculation by exporting control
It is partially converted into the control to asynchronous machine in balance adjustment mechanical device, it is achieved change balance of well pumping unit degree.A period of time
After, oil pumper is stable, repeats this step, reaches optimal oil pumper according to the method based on " extreme power " and runs optimal
The degree of balance.

Detailed description of the invention
For making the above and other objects, features and advantages of the present invention to become apparent, cited below particularly go out preferably to implement
Example, and coordinate shown in accompanying drawing, it is described in detail below.
As it is shown in figure 1, the input end of motor at beam pumping unit 0 connects electrical quantity acquisition module 2, wherein three-phase current connects
With transformation ratio current transformer 1.CPU6 is connected with electrical quantity acquisition module by serial communication circuit 3, it is achieved real-time voltage, electricity
Stream, the isoparametric transmission of power.
Angle acquisition module is vertically mounted on the surface of beam pumping unit 0 walking beam rotary shaft, by serial communication mould
Block 5 is connected with CPU6.For obtaining the position of bottom dead centre in the real-time position information that oil pumper runs, and determination.
Running status current for oil pumper, poised state and parameter information are sent to touch display screen 7 by CPU6, touch aobvious
These parameters are shown by display screen 7 in real time.Site operation personnel, by after display parameters analysis, can pass through touch display module 7
Send control command to CPU6.
CPU6 receives the data that electrical quantity acquisition module 2 gathers with angle acquisition module 4, calls respective algorithms and merges oil pumping
The information such as all of electrical quantity of machine, position, computational analysis simultaneously combines the command information touching display screen 7, after, the corresponding control of output
Data signal processed balances block motor-drive circuit 9, drives balance weight motor to change balance weight position, reaches what the degree of balance adjusted
Purpose.
More than should be only presently preferred embodiments of the present invention, and be not used to limit the scope of the claims of the present invention, other use this
The equivalence change of bright patent spirit, all should all belong to the scope of the claims of the present invention.
