Description
Technical field
The present invention is specifically related to a kind of electrically controlled and hydraulically and regulates the balance of well pumping unit device automatically.
Background technology
Oil pumper is the special equipment of oil, natural gas, cbm development.Our national oil exploitation method is a lot, and flowing well oil recovery, gas-lift production, rodlless pump oil recovery and pumping production or the like are arranged.Wherein, pumping production accounts for 85～90% of total producing well number, accounts for 70～75% of total oil production.Oil pumper is also used in natural gas well discharge opeing, coal bed gas well discharge opeing in a large number.One of primary structure pattern of oil pumper is a beam pumping unit, and its structure is formed and comprised horse head, walking beam, crossbeam, connecting rod, crank, bascule, base, reducer, belt transmission, motor, switch board, lubricating system or the like.During oil recovery, motor drives crank through reducer, connecting rod, and drive walking beam, horse head pump, and drive downhole pump work.
Hanger is hanging rod string and is pumping in the pumping production process, i.e. up stroke and down stroke.The motor driven oil pumper promotes rod string and the interior liquid of well in the oil gas well in the up stroke process, and it is descending that the interior liquid of rod string and well drags oil pumper in the down stroke process under the deadweight effect, and motor is in generating state.In order to reduce motor power (output), and avoid motor to do negative work, bascule is set on oil pumper usually; Be rod string and interior liquid dependence descending work of deadweight effect of well and motor work in the down stroke process; By the bascule deposit, in the up stroke process, the energy that bascule discharges deposit helps to promote liquid in rod string and the well; Compare when output power of motor is with no bascule this moment, can reduce significantly.Acting equates no matter oil pumper, is hoped motor in theory at up stroke or in the down stroke process.
In the oil recovery process,, make pump load often change, need this moment the adjustment weight to reach new balance because the complexity of pit shaft causes in the rod string motion process and the variation of the frictional resistance between the pit shaft and adopt variation of liquid measure or the like.Therefore, balance of well pumping unit is designed to the key for power-saving technology, and various balance modes are also more and more with device.At present, the adjusting overwhelming majority of balance of well pumping unit is artificial Field adjustment, as increasing or reduce the balance weight regulating block, increases or reduce the balance weight jib-length.This regulative mode is regulated for level is arranged, and is differential also bigger, operating difficulties, and counterbalance effect is bad.In order to realize the pumping production digital management, occurred a kind of electronic leading screw adjustment moment on the market in recent years, promptly the resuspended arm lengths of motor driven leading screw adjustment can realize electronic automatic adjusting.But balance regulator is a motion, complex structure, and the bascule quality is big, and adjusting device load in adjustment process is big, and damage, or adjusting device easily is exposed to the field for a long time, and corrosion, scab etc. take place easily, causes jam, makes to regulate to lose efficacy.
Summary of the invention
The object of the invention is intended to overcome the shortcomings and deficiencies on existing balance of well pumping unit device art and the function, provides a kind of electrically controlled and hydraulically to regulate the balance of well pumping unit device automatically.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of electrically controlled and hydraulically is regulated the balance of well pumping unit device automatically, it is characterized in that, said device comprises basic balance weight, additional liquid chamber, liquid feed device and counter-jib.
Said liquid feed device comprises feed tank, strainer, valve, pump and electromagnetic valve.
Said feed tank one end is drawn watering pipeline and is connected strainer, valve and pump successively, and connects introducing additional liquid chamber; The feed tank other end is drawn drainage pipeline and is connected electromagnetic valve, and connects introducing additional liquid chamber; Electromagnetic valve and pump connection control system.
Said basic balance weight and additional liquid chamber can be rectangular shape or drum.
Said basic balance weight can be steel work or precast monolithic reinforced concrete structure.
This programme has following beneficial effect with respect to prior art:
1, can weigh by remote or online adjustment, can weigh by the automatic or manual adjustment, degree of regulation is high.
2, bascule and adjusting thereof do not have movement parts, reliable operation.
3, simple in structure, low cost of manufacture.
Description of drawings:
Fig. 1 is an oil pumper structural representation of the present invention.
Fig. 2 is a balance of well pumping unit apparatus structure sketch map of the present invention.
Among the figure, 1-oil pumper, 2-counter-jib, 3-additional liquid chamber, 4-watering pipeline, 5-drainage pipeline, 6-basis balance weight, 7-liquid feed device, 7.A-strainer, 7.B-valve, 7.C-pump, 7.D-feed tank, 7.E-electromagnetic valve, 8-liquid.
The specific embodiment
Below in conjunction with specific embodiment this programme is done and to be further described:
In conjunction with Fig. 1 and Fig. 2; The described electrically controlled and hydraulically of this programme is regulated the balance of well pumping unit device automatically; By basic balance weight 6, liquid feed device 7, (like Fig. 1) formed with counter-jib 2 in additional liquid chamber 3; Basis balance weight 6 can be the rectangular shape or the drum of steel work or precast monolithic reinforced concrete structure, and additional liquid chamber 3 also can be rectangular shape or drum.As shown in Figure 2; Be provided with in the liquid feed device 7 and comprise feed tank 7.D, strainer 7.A, valve 7.B, pump 7.C and electromagnetic valve 7.E; Feed tank 7.D one end of liquid feed device 7 is drawn watering pipeline and is connected strainer 7.A, valve 7.B and pump 7.C successively, and connects introducing additional liquid chamber 3; The other end of the feed tank 7.D of liquid feed device 7 is drawn drainage pipeline and is connected electromagnetic valve 7.E, and connects introducing additional liquid chamber 3; Electromagnetic valve 7.E and pump 7.C connection control system.
This device is when increasing balance weight and regulate, and the control system gives an order and opens pump 7.C the liquid in the feed tank 7.D is pumped into additional liquid chamber 3, reach new balance after, the control system gives an order and closes pump 7.C.When need reducing balance weight, the control system gives an order and closes pump 7.C, and opens solenoid valve 7.E makes that the liquid in the additional liquid chamber 3 turn back in the feed tank 7.D, reach new balance after, the control system gives an order and closes electromagnetic valve 7.E.The effect of the middle filtrator 7.A of system is to avoid the impurity in the feed tank 7.D to get into pump 7.C and additional liquid chamber 3, and the effect of valve 7.B is to close when needing system maintenance such as maintenance or replacing pump, pipeline.
