According to Fig.2, in-site installation is carried out to oil pumping machine control cabinet, wiring order default left end connects just, and right end connects negative.
Pumping unit parameter, the parameter of electric machine, the taper of rod of sucker rod, pump diameter, the density of crude oil, moisture content, pipe aperture,
The static parameters such as sucker rod density, the Young's modulus of sucker rod, alarm measure are configured by configuration software.Complete static state
After parameter configuration, by solving the vibration equation of polished rod, the emulation indicator card of oil well pump is calculated.Alarm measure default setting
Are as follows: level fault stoppage protection；Secondary failure is shut down；Three-level fault warning；Default setting mode is used in the present embodiment.
As shown in figure 3, on the basis of pump dynagraoph calculates, the identification of progress function figure and analysis, characteristics extraction, the preliminary event of progress
Barrier diagnosis；Further by the processing of function figure nondimensionalization, progress pattern-recognition, detailed fault diagnosis is completed, and pass through history number
Confirm according to failure and special, completes final resultant fault analysis.Common pumping unit state includes starting, shuts down, power-off
The states such as protection, voltage lacuna, belt be disconnected, motor overload and underload.It can recognize that common oil pumping machine fault has travelling valve leakage
Mistake, standing valve leakage, the leakage of double valves, rod parting, sucker rod partial wear, oil well liquid-supplying deficiency, gases affect, gas lock,
Oil pipe leakage, pumping spray and wax deposition etc., the alarm measure of alarm module is divided into three kinds of warning, shutdown and stoppage protection strategies, foundation
The severity and potential hazard of failure distinguish.
According to the common state of pumping unit, corresponding in the present embodiment is set are as follows: level fault includes: gas lock, oil pumping
Bar disconnected de-, voltage lacuna, belt break；Secondary failure includes: that double valve leakages, standing valve severe leakage, travelling valve are serious
Leakage, serious feed flow are insufficient, serious gases affect, wax card；Remaining is three-level fault.
When carrying out fault diagnosis, the real time data acquired by sensor analyzes electric current, voltage, the function of oil well respectively
The data such as rate, surface dynamometer card and pump dynamograph determine the working condition of pumping unit, for suspected malfunctions, using mostly because
Plain comprehensive analysis；By the parameters such as load extreme value, displacement extreme value, function area of pictural surface in comparison historical data, if amplitude of variation is more than
Range, as failure are set, it is otherwise normal for hole condition.For diagnosing the failure without doubt, fail-safe operation is carried out by degree.
For three-level fault, failure is uploaded to host computer by communication module and is sent a warning message, communication module uses industrial mark
Quasi- 4GDTU, controller is communicated with host computer to be uploaded using standard Modbus agreement；For secondary failure, live warning letter is sent
Breath (light alarm and audible alarm), prompts Field Force to leave the theatre, then realizes and shut down, and fault type and operation are sent to
Position machine system.For shutting down caused by partial fault, staff by analysis, can realize that long-range starting is taken out in safe range
Oil machine.For three-level fault, only after troubleshooting, scene starting can just restore pumping unit and normally produce.For level-one
Failure sends alarm command, prompt system failure to host computer.
A in the present embodiment, the specifying information of oil well alarm includes AI alarm, DI alarm and oil well alarm；Each alarm
A corresponding key, can check corresponding warning message by depresses button；Display interface information as shown in Figure 6, AI alarm condition
It include: lower limit alarm under 0-AI normal, the upper upper limit alarm of 1-AI, 2-AI upper limit alarm, 3-AI, the alarm of 4-AI lower limit.Such as Fig. 7 institute
Show that display interface information, DI alarm condition are divided into normal and alarm two states, alarm condition includes: 1- high alarm report low with 2-
It is two kinds alert.It is illustrated in figure 8 oil well alarm indication interface information.
The fault diagnosis of pumping unit refers to using the indicator card of pumping unit as foundation, the mechanical parameter of bonding apparatus and the object of crude oil
Property parameter, for pumping unit and oil well failure carry out qualitative and quantitative analysis.It is different with influence according to the property of failure, it will
Oil pumping machine fault is divided into basic fault analysis and two class of accident analysis.It is different that basic fault analyzes Main Analysis pumping unit load data
Often, displacement data exception, empty pump, kelly, the disconnected basic faults such as bar and gas lock analysis.
Wherein, fault code: i.e. Fault Diagnoses of Oil Pump as a result, each represents a kind of failure, 0 be it is normal, 1 for therefore
Barrier.
Load data is abnormal: there is the excessive or too small load value not being consistent with the current swabbing parameter of oil well in load data.
Displacement data is abnormal: there is the excessive or too small shift value not being consistent with the current swabbing parameter of oil well in load data.
Empty pump: due to seriously owing liquid, cause the degree of filling of oil pumping pump minimum.
Kelly: the pumping rod fasterner due to caused by oil well liquid wax deposition, dirt or other reasons is in pit shaft, it is virtually impossible on
Lower movement.
Disconnected bar: sucker rod caused by overload due to being broken.
Holddown: it can not be moved since installation or well liquid cause oil well pump to be stuck in pit shaft.
