Description
Technical field
The present invention relates to the oil pumper in the petroleum machinery of oil field, especially relate to information-based digitlization energy-saving pumping unit.
Background technology
Current known oil pumper has traditional beam pumping unit and modern without beam pumping unit.The former has used more than 100 year, have sturdy durable, safe and reliable advantage, but efficiency is low, and energy consumption is high, adjusts ginseng difficulty.The latter is scientific research personnel's new architecture newly developed in recent ten years, advantage is that efficiency is high, energy-conservation, but manufacturing cost is high, poor reliability, later maintenance expense is high, the electricity charge of saving are almost used in later stage consumable accessory and have been gone again, therefore, lose more than gain, promote hard to carry on, on probation through after a while of most oil fields, through comparison, think or the relatively good use of beam machine, cause the problem low in efficiency, energy consumption is high, wish blue elephant adjustment technical graft to solve to beam pumping unit.
Summary of the invention
In order to overcome the above-mentioned defect of existing beam-pumping unit, maximize favourable factors and minimize unfavourable ones, the invention provides based on wifi network cloud service digits energy-saving pumping unit, can reach the sturdy reliable advantage of performance beam-pumping unit, can reach again that blue elephant is energy-conservation, efficient, the advantage of digital control, intellectual management.
The technical solution adopted for the present invention to solve the technical problems: take beam pumping unit as carrier, at walking beam afterbody, increase an arm, the mobile device of an automatic adjusting balance is set on arm, adopt information technology, on motor, embed electrical quantity sensor, in control system, adopt integrated circuit, software and relevant information components and parts, collection and the transmission of integrated oil well indicator card and electrical quantity, the parameters such as jig frequency, balance are regulated automatically with operating mode, and by operational factor and well site audio frequency and video real-time Transmission to wifi network cloud server.
Described automatic balancing device, by support, servomotor, shaft coupling, reductor, cylindrical gear, tooth bar, retainer, formed, Plane Installation tooth bar on arm, servomotor is connected with reductor by shaft coupling, they are arranged on support jointly, on the output shaft of reductor two ends, roller gear are installed, and this assembly is meshed with the tooth bar of arm, at speed reducer output shaft top welding retainer, to prevent that in running, Balame regulating device is thrown out of arm.Research and experiment shows, the system efficiency of pumping well of the ratio balanced differences that balance is good can improve 5%-10%, and the quality of balance of well pumping unit situation directly has influence on output torque size and application life and the oil pump running stationarity of reductor, motor.When horse head front side suspending point loading increases, original balance is destroyed, and motor moment of torsion in up stroke process increases, because of electric current and moment of torsion linear, therefore electric current also increases.Motor is in descending process, moment of torsion reduces, electric current also reduces, utilize the electrical quantity of motor to change and it can be reflected by control system, when the degree of balance surpasses the 85%-110% scope of setting, control system just can be sent action command to servomotor, by shifting balance device, just can obtain new balance, when front side load increases, servomotor and reductor and counterweight support just move laterally, until reach new balance.When front side load hour, servomotor and counterweight just move to the inside, until reach new balance.For this reason, dynamic adjustments balance can guarantee that oil pumper moves all the time under the good state of balance, and power consumption economizes most.
Described automatic control system is that autobalance, Electric Machine Control, monitoring of working condition is integrated as a whole, utilizes a set of control system to realize this three kinds of functions simultaneously.Integrated rear motor not only as a power source also as an information source, from the operational factor of motor, obtain required information.When balance is bad, motor is upstroke oil pumping and down stroke oil suction in running, and the moment of torsion of motor is different, and its electric current is also different, and during by judgement rise and fall, how the above-mentioned parameter of motor can know the degree of balance.Running status and traffic direction, upstream and downstream, moment of torsion, electric current, frequency, jig frequency all can obtain by the operational factor of motor, need not several sensors.
Described broadband wifi network is the network foundation as Oil-Well Monitoring System, adopts Yi Tai wifi main website, covers 50Km
2all oil wells in region, realize duty parameter audio video transmission, utilize the remote wifi bridge of solar energy and powered by wind energy, realize the oil well monitoring in depopulated zone, the Software for Design of monitoring system adopts high in the clouds structure, all monitor datas are all stored on cloud server, by web services, are published to each terminal.
Operating principle of the present invention is: beam pumping unit is a kind of quadric chain of distortion, and its complete machine structure is as a balance, and one end is oil pumping load, and the other end is counterweight.If the moment of torsion that oil pumping load forms with counterweight equates or changes consistent, with very little power, just can make oil pumper work uninterruptedly so, the power-saving technology that is to say oil pumper depends on the quality of balance, the power providing at degree of balance motor for 100% time is only for mentioning 1/2 fluid column weight and overcome friction, balanced ratio is poorer, and the power that needs motor to provide is larger.Because oil pumping load is all the time all to change, and counterweight can not be done on all four variation with oil pumping load.Can only be by regulating the arm of force of counterweight could realize balance.
The invention has the beneficial effects as follows apparent, the one, adopt dynamic leveling weighing apparatus, can guarantee that oil pumper power consumption economizes most.The 2nd, adopt the parameter of electric machine as information source, can obtain a large amount of oil well condition information.The 3rd, automatic adjusting balance, Electric Machine Control, work condition inspection is integrated as a whole, utilize a set of control system to realize this three kinds of functions simultaneously, saved a large amount of sensing equipments.The 4th, adopt broadband wifi network as the network foundation of Oil-Well Monitoring System, information-based new technology is introduced to oil pumper technical field, the resource that takes full advantage of network cloud service, instantaneous transmission duty parameter and well site audio frequency and video, reach remote-control romote-sensing, antitheft, safety, improves technical level and the competitiveness of oil pumper greatly, saves maintenance cost, alleviate labor strength, realized oil worker's patrol and do not used a century dream in field.
