Description
The utility model relates to a kind of oil-field oil pumper actuator, particularly a kind of oil-field oil pumper intelligent type energy saving actuator that adopts many power dragging motor and Control Technique of Microcomputer.
At present, the oil pumper actuator that uses in the oil field is that control cubicle is formed by high starting torque, high-slip threephase asynchronous and conventional low-voltage electrical apparatus control circuit.Its weak point is to have only simple functions such as phase shortage, overload, and protection speed is slow, and common electronic protector reliability is also relatively poor, and power can not mate, and the phenomenon of low load with strong power often occurs.Even adopt many power grades threephase asynchronous, also most people are power grade for a change, moves on high-power grade usually, does not reach the effect of power match.According to dynamic test to tens of used for oil extractor motor operational factors; load factor is accounting for three one-tenth more than 80%; (≤70%) of underloading accounts for seventy percent; meritorious and reactive power have been consumed in large quantities; caused severe energy waste; simultaneously, burning motor because of reasons such as phase shortage, overload protection are ineffective brings very big loss for the ordinary production in oil field.
The purpose of this utility model provides a kind of oil pumper reliability service of can protecting at above-mentioned weak point exactly, can adjust automatically according to loading condition again, makes motor operate in oil-field oil pumper intelligent type energy saving actuator on the rational power grade.
Technical solution of the present utility model is: a kind of oil-field oil pumper intelligent type energy saving actuator, comprise motor and control circuit thereof, and it is characterized in that: described motor is a three-phase asynchronous motor with multiple powers.Control circuit comprises microprocessor; the current detection sensor circuit that is connected between motor power-supply wire and the microprocessor input interface; give the power circuit of microprocessor power supply; the power of motor grade conversion control circuit that is connected with the microprocessor output interface, and overload, phase shortage, starting detect time-delay, short circuit, motor overheating protective circuit.
Motor described in the utility model technical solution can be many power of single speed high-slip energy-saving three-phase asynchronous motor.
Motor described in the utility model technical solution can also be how fast many power high-slip energy-saving three-phase asynchronous motor.
Microprocessor described in the utility model technical solution can be EASY412 series small PLC Programmable Logic Controller.
The utility model is owing to adopt three-phase asynchronous motor with multiple powers and microcomputer automatic control circuit, thereby after the dragging motor operation, by current detection circuit to the motor operating state detection of dynamic, then detected transfer of data is arrived the microprocessor input interface, after the Microcomputer Data analyzing and processing of gathering, the power grade parameter that automatic selection and present load are complementary, the A.C. contactor action of drive motor power grade conversion control circuit, thereby change the motor stator winding mode of connection, finally reach the purpose that changes power grade and rotating speed.The change of power and speed can be from big to small, otherwise also can change.In addition, microprocessor also has defencive functions such as automatic analysis and judgment dragging motor overload, phase shortage, starting detection time-delay, short circuit, motor overheating, has reached the purpose of protecting motor reliably.The utility model can make the load factor of dragging motor reach more than 80%, solve the not energy-conservation phenomenon of " low load with strong power " effectively, eliminated heavy manual labor simultaneously, improved operating efficiency, detect by the scene, apparent power integrated power-saving rate reaches 19%.
