Description
Technical field
The present invention relates to the oil production equipment technical field, particularly a kind of intelligent controlling system for beam-pumping unit.
Background technology
The production efficiency of existing control system is on the low side, the degree of filling of oil pump is not high, the production fluid amount is also on the low side, problems also occur on multiple special hole conditions such as viscous crude, feed flow deficiency, often occurs taking off such as sucker rod and takes out phenomenon, cause oil pumper seriously uneven, cause oil pumper overload, jig frequency that oil-extractor polish-rod is descending when being obstructed is non-adjustable, and the well of fluid supply capacity deficiency also needs artificially to control continually, consume a large amount of manpowers, this class phenomenon has had a strong impact on the application life of oil pumper.Programmable logic controller PLC controls computer as universal industrial at present, formed the tandem product of large, medium and small various scales, and standardization, seriation, modularization, be equipped with the various hardware units of great variety of goods to select for use for the user, the user can carry out system configuration flexibly and easily, the system that forms difference in functionality, different scales can be used for the Industry Control occasion of various scales; Along with improving constantly of industrial automatization, frequency converter has also obtained using very widely, frequency control is with its high efficiency, High Power Factor, and excellent speed governing and open plurality of advantages such as braking ability and be known as the most rising mode of speed regulation both at home and abroad.Man-machine interface such as the application of liquid crystal display (or touch-screen) also more and more widely.
Summary of the invention
The present invention provides a kind of and can eliminate oil pumper overload phenomenon and control the intelligence control system that oil pumper is regulated jig frequency automatically on the basis of existing technology.
Its technical scheme is: comprise frequency converter, programmable logic controller and man-machine interface, wherein said programmable logic controller connects frequency converter, load transducer respectively and near switch.Frequency converter is used to gather the electrical quantity information of motor, load transducer is used to respond to the load signal of oil pumper, the stroke displacement information that is used to detect oil pumper near switch, and send above information to programmable logic controller, through built-in process analysis, and sending control information, thereby the rotating speed of control motor to frequency converter.
Also be provided with the input of the rotary speed information of gathering motor on the described programmable logic controller.
The present invention can be according to the variation of oil pumper load; realize monitoring operational factor in real time; electrical quantity etc.; oil pumper is regulated descending jig frequency when being obstructed automatically in that polished rod is descending; reach the speed function of protection automatically; can also be according to the stepless adaptive speed regulation of oil well load change, and show the indicator card and the map of current of oil well.
