Abstract
The invention discloses an energy-saving drag automatic control device of an oil field oil pumping unit and belongs to the technical field of oil extraction equipment. The device is characterized in that changes of stratum feed flow, contained moisture and gas of an oil well enable polished rod loads to change constantly during working of the oil pumping unit, accordingly, the output torque of a motor is required to change along with the change of the polished rod loads. According to the energy saving drag automatic control device of the oil pumping unit, the working current of a variable torque motor is controlled in real time through a single chip microcomputer, the maximum current is identified, and a set time is stored, then the wiring mode of the variable torque motor is changed through an instruction execution circuit. The energy-saving drag automatic control device of the oil pumping unit has the advantages that inconveniences and delays caused by manual adjustment are solved, the downtime of the oil pumping unit is reduced, and the electric power energy is greatly saved.
Description
Technical field
The invention belongs to the oil production equipment technical field, relate to the energy-conservation automatic control equipment that drags of a kind of oil-field oil pumper.
Background technology
At present; To be still with beam pumping unit be main to the oil production equipment that uses of each oil field at home, and it is main that its mating power is still with motor, wherein through 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.Motor is changed in manual work, perhaps changes the mode of connection of variable output torque motor, and 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 through mode conversion switch, and current sampling circuit links to each other with the maximum current identification circuit, and 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 through 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 invention has the beneficial effects as follows:
Monitor the operating current of variable-torque motor in real time through 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 a circuit control principle block diagram of the present invention;
Fig. 2 is the energy-conservation automatically controlled circuit diagram that drags of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done and to further describe:
In Fig. 1 circuit control principle block diagram, constantly obtain the operating current data of variable-torque motor through current transformer; Be transported to maximum current identification and maximum current memory circuit; Through 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.
