Description
Technical field
The present invention relates to a kind of oil pumper frequency conversion and do not shut down tune stroke tune stroke-frequency device, belong to technical field of electric automation.
Background technology
The current oil pumping in oil fields electric motor overwhelming majority, or an original direction is run, by the circular motion of quadric chain by output end of reducer, convert the rectilinear motion up and down of sucker rod to, change stroke and jig frequency if want, must change the speed reducing ratio of diameter pulley or reduction box, its process extremely wastes time and energy.
Although variable frequency control installed by part oil pumper now, but original direction is run, motor can change the speed of motor easily by variable frequency control, namely changes jig frequency, but cannot stroke be changed, more not realize rotating frequently and run.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of oil pumper frequency conversion and not shutting down tune stroke tune stroke-frequency device, this device also can realize running three-phase permanent-magnetic synchronous motors and the frequent rotating of threephase asynchronous by variable frequency control.
The technical solution adopted for the present invention to solve the technical problems is: oil pumper frequency conversion is not shut down and adjusted stroke to adjust stroke-frequency device to be made up of housing, frequency converter, braking resistor, cooling fan, temperature controller A, temperature controller B, main power switch, accessory power supply switch, arrester, auxiliary reclay, standby electric power, transformer, rectifier bridge, electric capacity and heater, frequency converter in this device adopts the safe frequency converter model of Invertek English to be OPTIDRIVESP2,380V, 17 to 60Hz, power 11KW to 250KW, can control the frequent rotating of motor and run; Housing is a cuboid, its top is provided with waterproof edge, be connected with 4 lifting bolts between waterproof edge with housing, larger gap is had between waterproof edge and housing, on the housing of waterproof edge bottom, complete perforate, sheds in order to hot blast, is provided with rodent-proof mesh in housing bottom perforate, rodent-proof mesh is provided with electric-powered shutter, and electric-powered shutter is by electric-powered shutter Electric Machine Control.When in temperature controller A monitoring housing, temperature is higher than 30 DEG C, temperature controller A provides on-off model, and cooling fan runs and carries out air draft.When temperature controller B monitors that in housing, temperature is lower than 5 DEG C, temperature controller B provides on-off model, and electric-powered shutter is closed automatically.The front and back of housing are door-plates, and left and right is side plate, and blind hinge opened by front and back door-plate list, and front and back door-plate encryption strip of paper used for sealing, the second layer wicket after Qianmen is opened is provided with guidance panel; In enclosure interior, its top is provided with braking resistor, cooling fan is provided with in braking resistor bottom, side is in the middle provided with frequency converter, opposite side is provided with main power switch, accessory power supply switch, temperature controller A, temperature controller B, arrester, auxiliary reclay, transformer, rectifier bridge, electric capacity, standby electric power and heater, is provided with several prap in the bottom of housing.Oil pumper frequency conversion is not shut down and is adjusted stroke to adjust stroke-frequency device and oil pumper permasyn morot or asynchronous electric mechatronics.
Rodent-proof mesh is stainless (steel) wire.
Frequency converter is the vitals in this device; the frequency converter adopted in this device is the safe frequency converter of Invertek English; model is OPTIDRIVESP2, is from the external a kind of new type inverter introduced, and does not shut down and adjusts stroke to adjust jig frequency mainly to be come by this Frequency Converter Control.Braking resistor is declined by sucker rod, the heat that motor is in generating state and resistance generation blows out outside housing by cooling fan, temperature controller A controls cooling fan, in housing, during temperature height, temperature controller A provides on-off model, cooling fan starts discharges hot blast outside housing, when temperature is low, cooling fan is automatically out of service; Temperature controller B controls electric-powered shutter according to the temperature of setting and starts or close, simultaneously the also work of control heater or stopping, and other parts are parts conventional and general in automation engineering.
The safe frequency converter model of Invertek English is that OPTIDRIVESP2 can realize not shutting down online oil pumper permasyn morot and asynchronous motor adjusting stroke to adjust jig frequency easily, can realize position control easily, namely achieve tune stroke; Change the output frequency of frequency converter, namely change the revolution of motor, namely achieve tune jig frequency.Run because this device can control the frequent rotating of motor again, can quadric chain be dispensed from machinery, realize the linear reciprocating motion that sucker rod is upper and lower.
Arrange a meta proximity switch in the centre position of an oil pumper stroke, the error that the every action of meta proximity switch once produces a stroke resets and resets once, and such oil pumper running does not exist cumulative errors.Add top dead centre and lower dead center protects travel switch in its both sides maximum travel position, the motor inverted running immediately when switch motion, do not touch top dead centre and lower dead center travel switch when oil pumper normally works, when oil pumper is run, safety greatly improves.
The present invention also can realize oil pumper when running to close to top dead centre and lower dead center, any setting downtime then inverted running again, such as set the time at several seconds zero point, such hommization and flexibility run and substantially improve the harder mechanical property of original oil pumper, as when sucker rod runs to lower dead center, there is great descending potential energy in overall sucker rod, now sucker rod is up dragged again by force, sucker rod is in such state stretched by tug-of-war by force for a long time, its consequence is the mechanical fatigue accelerating sucker rod, the application life of sucker rod is greatly reduced, it is the most common failure of field produces that sucker rod breaks.
Inside is provided with standby electric power, can provide power supply when monitoring to monitoring equipment.
Beneficial effect of the present invention is: the present invention can realize not shutting down online oil pumper permasyn morot and asynchronous motor adjusting stroke to adjust jig frequency easily; run because this device can control the frequent rotating of motor again; quadric chain can be dispensed from machinery; realize the linear reciprocating motion that sucker rod is upper and lower, as balance type beam-pumping unit.This device drives permasyn morot can omit reduction box more simultaneously, and the fault rate of oil pumper and cost are significantly reduced.Oil pumper adopts the flexibility of this device to run to there will not be sucker rod to break problem, and only this item can save a large amount of manpower and materials every year.
Have employed the most succinct mentality of designing during this apparatus design, do not adopt the corollary equipments such as PLC, single board computer, encoder during design, also namely avoid the potential safety hazard that many corollary equipments bring, the reliability of this plant running and life-span are greatly improved.
Its difficult point that realizes of this device is motor commutation and position control, not fantasy now, neither talk about stratagems on paper, there now have been actual product out and out in operation on Daqing oil field rod-pumped well, the design reaches all targets of expection, stable and reliable operation.
