Abstract
The utility model relates to an energy-saving driving device for an oil-pumping machine for an oil well, comprising an induction motor which is often used. The induction motor is provided with a control device which is used for controlling the soft starting of the induction motor. The output shaft of the induction motor is connected with a driving shaft which is provided with a flying wheel by one shaft coupling. A friction clutch is arranged on one side of the flying wheel. A belt wheel is arranged on another end of a clutch shaft. Output torque is transferred onto a speed reducer by belt transmission. Rotary motion is converted into up and down motion by a connecting rod and a crank to drive a walking beam which accepts a supporting frame as a supporting point. Another end of the walking beam is provided with the horsehead of the oil-pumping rod of an oil-pumping machine. The oil-pumping rod moves from top to bottom to enhance crude oil from the bottom of an oil well to a ground.
Description
The utility model relates to a kind of energy-saving driving device that is used for pumping unit of well, belongs to oil exploration equipment.Oil pumper uses a kind of incorgruous crank device to promote crude oil from the oil well of accomplishing fluently, and the horse head of oil pumper drives sucker rod and moves up and down, generally is referred to as upstroke and down stroke.When upstroke, added load on the sucker rod, drive motors has also increased load, in the cycle of whole service, loads on variation constantly, is sharp cutting edge of a knife or a sword load value when load is maximum, and when down stroke, motor is near no-load running.
Existing oil pumper often is equipped with the heavy-duty motor that adapts with sharp cutting edge of a knife or a sword load and drags in order to overcome sharp cutting edge of a knife or a sword load, to guarantee oil pumper normally operation under the load that changes.The power of electric motor that oil pumper was equipped with in oil field is the three-phase alternating-current induction motor of 30KW to 55KW at present, and when the quantity of this drive unit was quite a lot of, energy consumption was quite a lot of.
In existing oil pumper technology; use incorgruous crank device can drag oil pumper work And and obtain certain energy-saving effect, but this device has a lot of shortcomings, at first is that energy-saving effect can't be satisfactory with the motor of smaller power; during shutdown; need to use manually-operated, make it to stop on the needed angle, secondly; institute's adapted power of electric motor also requires bigger, if the less motor of adapted can't overcome the sharp cutting edge of a knife or a sword load of oil pumper again.
In order to overcome above-mentioned shortcoming of the prior art, the purpose of this utility model is, a kind of energy-saving driving device of oil pumper is provided, this device promotes in the process of crude oil at oil pumper, can overcome sharp cutting edge of a knife or a sword load with less power, thereby saved electric energy, that is to say, can select for use the motor of smaller power just can guarantee oil pumper normally operation reposefully under the condition of loading that changes.This drive unit manufacturing simultaneously is simple.
The technical scheme that the utility model adopted is as follows: energy-saving driving device is provided with an induction conductivity, can control this electric motor starting voltage vertical 0 and progressively rise to 380 volts of full voltages, and the revolution of axle reaches rated revolution from low to high, finishes soft start.The motor output shaft that links with it drives a flywheel and rotates, and after reaching rated revolution, flywheel has had rotation inertia force, and its size is relevant with quality, and turning cylinder links by friction clutch and belt pulley and trailing oil pumper.When the sucker rod of oil pumper moved downwards, drive unit was equivalent to no-load running, and flywheel stores the inertia energy, when sucker rod upwards moved, drive unit was bearing fully loaded, when load reaches sharp cutting edge of a knife or a sword load, flywheel discharges the inertia energy, makes oil pumper still cross sharp cutting edge of a knife or a sword load reposefully and operate as normal.Proof is used this device by experiment, can select the power of electric motor specification for use not according to sharp cutting edge of a knife or a sword load, and selects to be lower than the motor of aforementioned power 50%, thereby has saved electric energy.
Below by accompanying drawing embodiment of the present utility model is elaborated:
Fig. 1: be the general structure schematic diagram of the oil pumper that is used for oil well.
Fig. 2: be the energy-saving driving device structural representation of oil pumper.
With reference to shown in Figure 1, energy-saving driving device 1 is arranged at ground, and it links by the belt pulley 5 on belt pulley 2 and connecting belt 3 and the reducer 4, and the output shaft of reducer 4 is connected with the connecting rod of oil pumper 6, connecting rod 6 links to each other with crank 7, and the other end of crank 7 is provided with a counterweight block 8; A beam travelling supporting frame 9 vertically is located at ground 13, is supporting the walking beam 10 of upper end.One end of walking beam 10 links to each other with described connecting rod 6 articulating joints, and the other end of walking beam 10 is equipped with pumping unit horsehead 11, sucker rod 12 is housed on horse head 11 is used for extracting crude oil in the well.When drive unit 1 drivening rod 6 moved up and down, horse head 11 drove sucker rod 12 and moves up and down, during up stroke, is being with crude oil full-load run, then no-load running during down stroke.
With reference to shown in Figure 2: energy-saving driving device 1 comprises an induction machine 14 commonly used, and induction conductivity 14 is loaded on the base 15, and control device of electric motor 16 is housed above motor 14, is used for controlling the soft start of motor.By shaft coupling 17, the output shaft of motor 14 and flywheel 18 link, side at flywheel 18 is provided with a friction clutch 19, and the driving shaft axle head of this clutch 19 is equipped with a belt pulley 2, and the moment of torsion of drive unit output then reaches on the reducer shown in Figure 14 by belt transmission.The effect of flywheel 18 in whole operation process of described drive unit 1 is storage power and releasing energy, when oil pumper no-load running, and the flywheel storage power, when oil pumper full-load run promptly reached sharp cutting edge of a knife or a sword load, flywheel released energy, thus but saves energy.
