Description
Technical field
The utility model relates to the in good time balanced energy conservation of a kind of beam pumping unit system.
Background technology
Because of underground crude oil oil level, oil include the variation of sand, moisture, paraffin, surface temperature, make and the continuous change of load of oil pumper cause being equilibrated at constantly of beam pumping unit to change.
The former Soviet Union has paid attention to the adjusting of the in good time balance of beam pumping unit as far back as the sixties, bring into use the in good time leveling regulating system of the Pneumatic controller 17 preposition cylinders of control, referring to Fig. 2, but because the sealing and the wearing and tearing of cylinder, make cylinder short maintenance cost height in 16 application lifes.Make that this technology do not have to promotion and application.Another kind of referring to Fig. 1, be rearmounted slide block 14 in good time balance-conditioning systems, because of big (because of oil-extractor polish-rod disconnects or the walking beam system is subjected to during disengagement impact is big, it is oversize that adjusting leading screw 15 can not be done to the increase of walking beam system weight.) need to increase slide block weight and strengthen torque adjusting, so increased, reduced the equipment operational reliability because of the impact that oil-extractor polish-rod disconnects or the walking beam system is subjected to when throwing off.System regulates, the control more complicated.This technology do not have yet to promotion and application.
China's beam pumping unit has more than 70,000 at present.According to rough Statistics beam pumping unit working condition, the having 17%, in a basic balance account for 34% of beam pumping unit complete equipilibrium, unbalancedly account for 32%, serious unbalancedly account for 17%.There is the beam pumping unit of half to be operated in non-equilibrium state as can be seen nearly by above statistics.
Summary of the invention
The utility model purpose provides the two in good time balanced energy conservation of the fuel tank beam pumping unit systems in a kind of front and back, with overcome make in the prior art low with running cost height, reliability, regulate the defective that control is complicated, operational reliability is poor, the counterweight amount is big.
Technical solution of the present utility model is:
The two in good time balanced energy conservation of the fuel tank beam pumping unit systems in a kind of front and back, its special character is: the gear pump, motor, motor controller, hydraulic oil, first container, second container, first sensor and second sensor that comprise two-way operation, but described gear pump and motor are arranged on walking beam middle part and motor driven gear pump work, described first container and second container are used to place hydraulic oil, it is arranged at the both ends of walking beam respectively, and described first container and second container top are respectively installed the oil-hole cover of a band waterproof exhaust-valve; The bottom of described first container and second container links to each other by oil pipe, the middle part of described oil pipe is connected with gear pump, described first sensor is arranged on the walking beam, it can detect the up-down stroke duty, described second sensor is arranged on the input of motor controller, it can detect motor operating current and voltage and current and phase difference in real time, and described motor controller turns to and rotation time according to the signal controlling motor of the first sensor and second sensor.
An oil level switch is respectively installed in the upper end of above-mentioned first container and the second container bottom oil-out.
The volume of above-mentioned first container and second container equates.
Technique effect of the present invention is:
1, reliability height.The utility model can not cause the wearing and tearing of balance sysmte and the significantly increase of weight, so can improve reliability by the mobile balance that reaches of hydraulic oil in two containers.
2, installation, running cost are low.Technological deficiencies such as wearing and tearing owing to having avoided existing in the prior art make cost of the present utility model descend naturally.
3, two containers of the present utility model are installed on the walking beam, the hydraulic oil of can after installing, annotating again, and gear pump and motor can be installed in the top of walking beam support point.Be convenient to install, also be convenient to maintenance.
4, the counterweight amount of using with respect to big, the same adjusting range of moment of balance weight adjusting Unit Weight change is few.(the utility model moment changes L=walking beam length overall * counterweight, and balance weight is regulated moment and changed L=leading screw adjusting length * counterweight.)
5, energy-conservation.The utility model can make beam-pumping unit only overcome frictional resistance work moment adjustment before and after the oil pumper, thereby reaches purpose of energy saving.
6, the utility model can be avoided driving the motor rotation because of walking beam is uneven and produce the generating effect.

The specific embodiment
The two in good time balanced energy conservation of fuel tank beam pumping unit systems comprise the gear pump 5 of two-way operation before and after the utility model, motor 7, motor controller 9, hydraulic oil, first container 2, second container 3, the first sensor 8 and second sensor 10, but gear pump 5 and motor 7 are arranged on walking beam 1 middle part and 5 work of motor 7 driven gear pumps, first container 2 and second container 3 that volume equates placed at the both ends of walking beam 1 respectively, place hydraulic oil in it, the oil-hole cover 12 of a band waterproof exhaust-valve is respectively installed at first container 2 and second container, 3 tops, respectively adds the hydraulic oil of container total capacity 50% in first container 2 and second container 3 by the oil filler point of oil-hole cover 12; The bottom of first container 2 and second container 3 links to each other by oil pipe 4, the middle part of oil pipe 4 is connected with gear pump 5, first sensor 8 is arranged on the walking beam 1, it can detect the up-down stroke duty, second sensor 10 is arranged on the input of motor controller 9, it can detect motor operating current and voltage and current and phase difference in real time, and motor controller 9 turns to and rotation time according to the signal controlling motor of the first sensor 8 and second sensor 10; Also can an oil level switch 11 respectively be installed in the upper end of first container 2 and second container, 3 bottom oil-outs.
When working, oil pumper, can record horse head 13 equalising torque situation before and after the walking beam when moving up and down of beam-pumping unit by second sensor 10 on first sensor on the walking beam 18 and the motor 7.As it is little to detect the horse head end moments, gear pump 5 is extracted into an amount of hydraulic oil in first container 2 from second container 3 under the driving of motor 7, thereby thereby the weight that increases oil in first container 2 has strengthened the moment of horse head end and reduced the moment that second container, 3 interior oily weight have reduced walking beam 1 tail end.Otherwise as it is big to detect the horse head end moments, then gear pump is extracted into an amount of hydraulic oil in second container 3 from first container 2 under the driving of motor, thereby thereby the weight that reduces oil in first container 2 has reduced the moment of horse head end and increased the moment that second container, 3 interior oily weight have increased walking beam 1 tail end.Thereby make the oil pumper walking beam reach balance.In order to prevent that gear pump 5 from sucking air and causing the pump housing to damage, an oil level switch 11 is respectively installed in upper end at the bottom hydraulic fluid port of first container 2 and second container 3, no matter which kind of condition lower tooth wheel pump 5 stops from then on to pump in the container when pasta arrives the upper end of bottom hydraulic fluid port, and can only give oiling in this container.Because of oil-hole cover 12 is equipped with the waterproof exhaust-valve, first container 2, second container, 3 internal pressures and the external world are consistent.
