It includes controller, motor electric quantity collection unit, communication module, controller and the unit connection of motor electric quantity collection, the interface is gathered to the dynamo power supply control box to the unit connection of motor electric quantity collection, communication module connection director, the controller is connected with the display. The utility model discloses a having solved the sucker rod and having supervised time measuring for a long time, it is more loaded down with trivial details to measure the indicator card, and the load sensors monitor in -process of measuring the indicator card produces the drift very easily, leads to the measuring result to be inaccurate. It is very simple that the motor electrical parameter is measured to electric work picture monitor, can carry out the real -time measurement to the motor. Through the change to motor electricity power curve, can monitor the operating mode of analysis sucker rod and judge.
Description
Technical field
This utility model relates to a kind of based on sucker rod electric work figure monitor, belongs to petroleum works field, is applied to structural safety health monitoring industry.
Background technology
Current domestic and international commonly used indicator card diagnosis down-hole pump working condition and liquid measure analysis, by rod-pumped well indicator card, can truly reflect oil well production operating mode.Owing to along with High water cut block rod and tube partial-wear, formation sand production is serious, oil well lost efficacy frequently, and typical case's indicator card can tentatively judge the reference frame of pumping unit well pump as production scene.By the analysis of indicator card, can analyze with accurate instruction oil well condition and management.
At present for the existing more research of indicator card diagnostic techniques of rod-pumped well operating mode, substantially be can interpolate that the working condition of producing well by indicator card.But the measurement of indicator card is comparatively laborious, domestic and international commonly used integration load device measuring sucker rod indicator card, its principle is all based on this electrical bridge principle of favour, is made up of the part such as strain resistor, measuring circuit.The installation site side of being confined to blocks between polished rod eye, and installation is inconvenient for, and due to elastomeric material and foil gauge characteristic, in permanent sucker rod operational monitoring, load data has significantly drift, causes the indicator card obtained deviation occur.The power section of sucker rod is to have a motor to provide, and can obtain the indicator card of sucker rod with indirect conversion by measuring the electrical quantity of motor.Oil pumper electrical quantity is the physical quantity being easier to record, and when sucker rod operating condition changes, polished rod load changes, and then causes the change of motor electrical quantity, so the operation electrical quantity of motor can be equally used for sucker rod operating condition analysis.
Summary of the invention
For above-mentioned problem, this utility model patent purpose is to propose a kind of monitoring instrument measuring the parameter of electric machine, by measuring the change of the electrical quantity in motor operation course, obtain the electrical power change curve of motor, during use, can change according to the electric power curves of motor, analyze the operating mode that sucker rod runs.
This utility model to achieve these goals, adopts the following technical scheme that
A kind of based on sucker rod electric work figure monitor, it includes controller, motor electric quantity acquisition unit, communication module；
Controller is connected with motor electric quantity acquisition unit, and motor electric quantity acquisition unit is connected to motor power control chamber acquisition interface；
Communication module connects controller, and controller is connected with display.
Described display is touch display.
Described communication module is DTU.
In electric work figure monitor running, sending the electric work diagram data gathered to server, all sucker rod electric work diagram datas are processed and show by server.Electric work figure monitor is arranged on inside motor control box, facilitates in-site installation and parameter identifier.Compare indicator diagram measurement, in electric work figure test process, be not required to unload sucker rod, directly measure the parameter of electric machine, reduce the unloading damage to sucker rod.
The beneficial effects of the utility model:
When this utility model patent solves sucker rod long term monitoring, measure indicator card comparatively laborious, be easy to produce drift during measuring the load transducer monitoring of indicator card, cause the result measured to be inaccurate.It is very simple that electric work figure monitor measures motor electrical quantity, can measure motor in real time.By the change to motor power curve, the operating mode judgement analyzing sucker rod can be monitored.Comparing indicator card acquisition system, electric work figure monitor saves manpower, financial resources, it is possible to achieve continuous print sucker rod operational monitoring and fault real-time early warning.Avoid simultaneously and unload the damage for sucker rod.
Accompanying drawing explanation
Fig. 1 is structural schematic block diagram of the present utility model.
Detailed description of the invention
1 pair of this utility model is described in detail below in conjunction with the accompanying drawings:
A kind of based on sucker rod electric work figure monitor, it include controller 6, motor electric quantity acquisition unit 4,5, communication module 1；
Controller 6 is connected with motor electric quantity acquisition unit 4,5, and motor electric quantity acquisition unit 4,5 is connected to motor power control chamber acquisition interface 2；
Communication module 1 connects controller 6, and controller 6 is connected with display 3.
Described display 3 is touch display.
Described communication module 1 is DTU.
After installation, open electric work figure monitor power supply, monitor operational factor is set, start sucker rod work.Sucker rod electric work figure monitor motor in real time operational factor, according to the parameter arranged, calculated for collection electric work figure can be shown on touch display screen, electric work figure curve data is uploaded onto the server by DTU simultaneously, after treatment, by data display and be saved in data base, analyze for later stage electric work diagram data.Meanwhile, the operating condition of sucker rod can also be analyzed by scene by the electric work figure of Real-time Collection.
