Abstract
The utility model relates to an energy saving drag automatic control device of an oil pumping unit, and belongs to the field of oil extraction device technology. A mutual inductor primary coil is connected with a variable output torque motor; a secondary coil is connected with a current sampling circuit via a mode conversion switch; the current sampling circuit is connected with a highest current identification circuit; the highest current identification circuit is connected with a highest current storage circuit; the highest current storage circuit is connected with an executive circuit via a time-delay circuit; the executive circuit is connected with a torque conversion circuit; the torque conversion circuit is connected with a variable torque motor; and the executive circuit is also connected with a manually-operated switch. The beneficial effects of the device is that the inconvenience and the time delay brought about by the artificial adjustment are solved, the down time of the oil pumping unit is reduced, and the electric power energy of the oil pumping unit is greatly saved.
Description
Technical field
The utility model belongs to the oil production equipment technical field, relates to the energy-conservation automatic control equipment that drags of a kind of oil-field oil pumper.
Background technology
At present, the oil production equipment of each oil field use is still based on beam pumping unit at home, and its supporting power is still based on motor, wherein by changing the stator tap mode of connection, make it to change the variable-torque motor of torque, because its superior electric property is widely used.Oil pumper like this could saves energy at work because oil well stratum feed flow own and variation moisture, gassiness constantly change polished rod load, and this also can change along with the variation of polished rod load with regard to the output torque that requires motor.Manually change motor, perhaps change the mode of connection of variable output torque motor, promptly time-consuming effort again is difficult to reach in good time adjustment.
Summary of the invention
The objective of the invention is:
Provide a kind of oil pump energy-saving to drag automatic control equipment.
Technical scheme of the present invention is:
Primary winding of mutual inductor links to each other with variable output torque motor, secondary coil links to each other with current sampling circuit by mode conversion switch, current sampling circuit links to each other with the maximum current identification circuit, the maximum current identification circuit links to each other with the maximum current memory circuit, the maximum current memory circuit links to each other with executive circuit by delay circuit, executive circuit links to each other with the torque conversion circuit, and the torque conversion circuit links to each other with variable-torque motor, and executive circuit also links to each other with hand switch.
The beneficial effects of the utility model are:
Monitor the operating current of variable-torque motor in real time by single-chip microcomputer, identify maximum current and store a setting-up time, instruction execution circuit changes the mode of connection of variable-torque motor then, reaches optimum Match.Promptly solve inconvenience that artificial adjustment brings and untimely, made oil pumper reduce downtime, saved the electric power energy of oil pumper again in a large number, simple in structure, reasonable in design, reliable operation.
Description of drawings
Fig. 1 is the utility model circuit control principle block diagram;
Fig. 2 is the energy-conservation automatically controlled circuit diagram that drags of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
In Fig. 1 circuit control principle block diagram, constantly obtain the operating current data of variable-torque motor by current transformer, be transported to maximum current identification and maximum current memory circuit, by the time-delay command executive circuit, change the mode of connection of variable-torque motor.
CPU is the primary processor of being made up of single-chip microcomputer and peripheral cell in Fig. 2, and KM1～KM6 is for changing the A.C. contactor of the variable-torque motor mode of connection, and M is a variable-torque motor.
