Abstract
The utility model discloses an automatic interim-opening controller for pumping unit, comprising a time-delay relay, an intermediate relay and an alternating current contactor which are controlled by a micro computer time-control switch controller, and a normally open contact of the alternating current contactor gets connection in series with a power cord of power supply of a pumping unit motor. It is suitable for the oil well short of liquid supply for the automatic interim-opening for the pumping unit. It has features of simple structure, low cost, easy use, strong adaptability, convenient maintenance and suitable popularization.
Description
Affiliated technical field
The utility model relates to a kind of and drives control device, especially a kind of automatic spacing working controller of pumping unit of well that is adapted in the oil field.
Background technology
Along with beginning for a long time of oil field, oil and underground fluid supply capacity constantly descend, so the time have the oil well of feed flow deficiency to occur, to this type of oil well if take full-time production can cause for some time in dry tap, thereby cause waste of energy and unnecessary pump wearing and tearing.In order to address this problem, at present, mostly take two kinds of methods, the one, by on the polished rod of oil pumper, installing the method for load sensor additional, with the opening of down-hole load variations signals collecting arrangement back control oil pumper, rest point and quiescent interval, thus opening between realizing of task.The 2nd, the way that changes by the motor working current that detects on the oil pumper, and this current changing signal is transformed into control signal, in order to the opening of control oil pumper, rest point and quiescent interval, thus opening between realizing of task.These two kinds of methods, though opening between can realizing of task, because these two kinds of controllers have complex structure, cost height, big, the open-air bad adaptability of maintenance difficulty, to detect error big, so be difficult to popularize.
Summary of the invention
Task of the present utility model be for the oil field provide a kind of simple in structure, make low, easy to use, adaptability strong, be convenient to keep in repair, be suitable for the automatic spacing working controller of universal oil pumper.
For realizing above-mentioned task; the technical scheme that the utility model is taked is: three normally opened contacts that are serially connected with motor protecter and A.C. contactor on the power supply line on the motor of oil extractor successively; on any two-phase power lead of power supply line, be connected with two ends of the primary coil of transformer respectively; one end of transformer secondary wire coil is connected with the common port of switch after by the output contact of motor protecter; one normally opened contact of switch by the button switch that stops key after with and the end that is connected to the start button switch of A.C. contactor normally opened contact be connected; the other end that starts keyswitch is connected with an end of A.C. contactor actuating coil and by being connected with output terminal on the micro computer time switch behind the normally opened contact of auxiliary reclay; input end on the micro computer time switch is connected with another normally opened contact of switch; one contact of the short-circuit line on the other end of A.C. contactor actuating coil and the micro computer time switch is connected; another contact of its short-circuit line is connected with the other end of transformer secondary output coil, the series circuit that is connected with the actuating coil of the time relay and the series circuit of forming with the normally closed contact of auxiliary reclay by raising one's voice between the short-circuit line contact on the micro computer time switch and its output terminal respectively and is made up of the normally opened contact of the auxiliary reclay actuating coil and the time relay.
Owing to taked technique scheme, the utlity model has following working method.Manual work mode: switch is placed the retaining that is connected with stop button, and make the start button closure, the short-circuited coil of stop button, start button, ac contactor coil, micro computer time switch to the lower end of transformer secondary output coil forms the closed-loop path, thereby formation current return, at this moment, owing to A.C. contactor gets electric work, it is serially connected in three normally opened contact closures on the motor of oil extractor power lead, make this motor get electric work, thereby realize making the task of oil pumper work.When pressing stop button it disconnected, this moment A.C. contactor the actuating coil dead electricity and make its normally opened contact be converted to disconnection by closure, thereby cut off motor work, thereby realize the out-of-work task of oil pumper.
Automatically working method: switch is placed when input end on the micro computer time switch is connected retaining, power supply by the upper end of transformer secondary output coil through the micro computer time switch to circuit supply, the work of the motor of oil pumper at this moment is controlled by the internal work situation of micro computer time switch, when micro computer time switch timing working, the inner contact closure, the time relay gets electric work trigger, working current is powered to loudspeaker by the normally closed contact of auxiliary reclay simultaneously, speaker operation is sent be about to start shooting the audio alert signal, its normally opened contact closure makes auxiliary reclay work when this time relay time-delay finishes, normally closed contact of relay disconnects in the middle of it, the loudspeaker outage quits work, this moment is because auxiliary reclay work, its normally opened contact closure makes the work of A.C. contactor, it is serially connected in the normally opened contact closure on the motor current supply circuit, thereby makes motor get electric work.In said process after the micro computer time switch regularly finishes, this moment, its inner contact disconnected, time relay dead electricity quits work, its normally opened contact transfers normally open to by closure, and auxiliary reclay quits work, and normally opened contact of relay transfers normally open to by closure in the middle of it, the A.C. contactor dead electricity is quit work, make the normally opened contact on the motor current supply circuit transfer normally open to, thereby cut off the power supply of motor, motor is quit work by closure.The liquid level build-up situation realized by the setting to the micro computer time switch after the stop and start of the motor in the above-mentioned course of work can stop well according to oil well interval time.
The utlity model has following beneficial effect: the one, owing to taked the technical scheme of micro computer time switch, open the task of control between can effectively realizing automatically as the major control parts; The 2nd, the utlity model has simple in structure, easy to use, be convenient to keep in repair, adaptability is strong, be suitable for universal characteristics.
