Time makes travelling valve and the ball sealer of fixed valve have sufficient unlatching and fall after rise the time, improves sealing effect, reduce fluid
Leakage, significantly improves pump efficiency.
The pendulum model constant level intelligent oil pumping machine of the present invention, can realize intelligent oil pumping, intelligence system includes：Constant level is taken out
Oil, automatically generate indicator card, calculate Liquid output, manually adjust ginseng, take out, fault alarm is shut down, hander monitors, remotely supervises on the spot
Pumping unit production figures management is completed in control, is described as follows：
Constant level is pumped：It reduces mechanical strength, ensure that the yield of optimization and system pressure make pumping unit mechanically and electrically
Reach equilibrium state in control, system effectiveness is made to be under optimum state and is run.Bringing formula by real-time polished rod load has
Work(power-mechanical loss power=Draw active power, be calculated uplink, under
Mean power during row is poor, automatically adjusts the speed of pumping unit rotating speed by the size of power difference, closed loop is formed with difference power
Control is pumped with reaching constant level.
Generate indicator card：The drafting of conventional indicator card needs to be grasped at the scene with special instrument and professional staff
Make, but this pumping unit solves this difficulty, it is only necessary to which work of recovering the oil opens hander on monitored picture or at the scene can be straight
It connects and shows indicator card.Oil recovery work is facilitated more to be fully understood by working condition under rod-pumped well.By gathering in frequency converter constantly
Formula is brought in torque intoIt draws polished rod load, gather in real time and stores uplink starting point to eventually
Load and displacement when point, downlink starting point are to terminal draw the curve of load of uplink and downlink, according to oil pumping rod area,
Oil pipe sectional area, coefficient of elasticity, lower-continuous mapping, fluid column weight bring formula estimation loss of plunger stroke into, determine that uplink opens a little and downlink
It opens a little in the position of displacement coordinate, can realize the drafting of indicator card.
Calculate Liquid output：Indicator card is identified in analysis by software, calculates the sucking factor of pump, discharge factor and fill
Full factor, oil pump diameter, piston stroke length, stroke of polished rod, jig frequency bring the lifting rate that formula calculates pump into, so as to which conversion be obtained
Effective discharge capacity can meet the measure of production, realize the requirement of guidance adjustment development plan.
Manually adjust ginseng：When pumping unit needs operation manually, the stroke of hander modification pumping unit, jig frequency, mistake can be passed through
Carry and take out frequency between shutdown value, adjustment, arbitrarily changed by production requirement without shutting down, can start and stop pumping unit at an arbitrary position, operation
It is very convenient.
Between take out：Function is taken out between being realized in the case of Liquid output wretched insufficiency, system presses cycle detection downhole data
Frequency is taken out between automatic calculating, fully improves pump efficiency.
Fault alarm is shut down：Frequency converter failure is shut down, electric current is more than setting value shutdown, sucker rod drags shutdown of having no progeny, motor
Overheating fault is shut down, casing pressure cancel closedown.Institute is faulty can to show simultaneously alarm in hander and monitoring system.
Hander monitors on the spot：Hander start input address selects respective picture observation pumping unit after dock successfully
All data and parameters are changed during operation, indicator card can also be shown on hander, and Field Force is facilitated to analyze reference.
Remote monitoring：Data after controller centralized processing are uploaded onto the server by GPRS remote transmission devices, by man-machine
Objective interface shows all data and alarm, alarm history is supported to check, history curve is supported to check and export printing, supports report
Table function, support oil well static data modification from addition, by different Department formation user rights.
