Abstract
A computer-control-based intermittent starter of an oil pumping unit mainly solves the problem that the current oil well cannot be intermittently started according to an actual load situation. The computer-control-based intermittent starter of the oil pumping unit is characterized in that: an A/D (analog/digital) converter, an MCS52 singlechip, a digital delay controller, a start and stop control circuit, a alarming voice prompting circuit and a connecting terminal row are arranged inside a starter shell, wherein a liquid level signal output end of an underground liquid level meter is connected with an analog signal input end of the A/D converter; a digital signal input end of the A/D converter is connected with a digital acquisition input end of the MCS52 singlechip; a control signal output end of the MCS52 singlechip is connected with a control signal input end of the digital delay controller; and the digital delay controller outputs a control signal for starting or stopping a motor to the start and stop control circuit. After the computer-control-based intermittent starter of the oil pumping unit is installed on an oil well, the intermittent start of the oil pumping unit can be realized; and the computer-control-based intermittent starter of the oil pumping unit has an energy-saving synergistic effect.
Description
Technical field
The utility model relates to a kind of device that is used for pumping unit control field on the oil field, specifically, relates to a kind of simple control gear that can realize the control of pumping unit intermittent pumping.
Background technique
The oil field of domestic majority has all been developed for many years at present; Be faced with the problem that many oil well oilbearing stratum oil reserves reduce; The problem of bringing simultaneously is difficult to satisfy the needed production fluid amount of pumping unit proper functioning exactly, causes to form that vacuum, load increase the weight of, mechanical wear is serious in the pumping unit pump housing and adverse consequences such as operating current increase.Simultaneously,, cause the waste of the energy, make that the cost of production of crude oil is improved greatly because extraction liquid reduces.
Summary of the invention
In order to solve the problem that exists in the existing technology pointed in the background technique; It is a kind of based on computer-controlled pumping unit starter at intermittence that the utility model provides; This kind intermittently starter can have the advantages that can reduce the pumping unit wearing and tearing, reduce energy consumption according to liquid level control pumping unit intermittent pumping actual in the oil well.
The technological scheme of the utility model is: this kind is based on computer-controlled pumping unit starter at intermittence; Comprise the underground liquid level meter, its unique distinction is: in the starter housing, include A/D converter, MCS52 single-chip microcomputer, digital delay controller, a startup and stop control circuit, an alarm voice cue circuit and a connecting terminal block; Wherein, The liquid level signal output terminal of said underground liquid level meter is connected to the input end of analog signal of said A/D converter; The digital signal input end of said A/D converter is connected to the data capture input end of MCS52 single-chip microcomputer, and the control signal output terminal of said MCS52 single-chip microcomputer is connected to the control signal input end of said digital delay controller; Said digital delay controller stops control circuit output actuating motor to said startup and plays machine shutdown control signal, and simultaneously, said digital delay controller starts alarm signal to said alarm voice cue circuit output; Said startup stops the contact of drawing of control circuit draws through said connecting terminal block, as with the interface of pumping unit electric control loop.
During concrete the realization; The preferred implementation of such scheme is: said digital delay controller adopts the TS23 type time relay; Said startup stops control circuit and adopts MY2NJ type auxiliary reclay, and said alarm voice cue circuit adopts the TY-6B type computerized speech plate that amplifies.
The utlity model has following beneficial effect: owing to take such scheme, the existing control box of this kind controller and pumping unit is directly realized connecting through terminal row, in addition, need not to remake to change and just can realize control to the pumping unit intermittent pumping.After using this device, judge by the liquid level signal that single-chip microcomputer is sent back according to level meter whether the liquid level in the oil well reaches the state that can extract, if be passable, then starts pumping unit work, if cannot, then do not start.After using this kind starter; Can control the operation of pumping unit automatically, need not the operator guard, like this; All can acquisition section during the pumping unit each run to satisfy the needed production fluid amount of pumping unit proper functioning; Avoided forming in the pumping unit pump housing problem of vacuum, practiced thrift the energy simultaneously, reduced the cost of production of crude oil thereby reduce mechanical wear.

Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; This kind is based on computer-controlled pumping unit starter at intermittence; Comprise the underground liquid level meter, its unique distinction is: in the starter housing, include A/D converter, MCS52 single-chip microcomputer, digital delay controller, a startup and stop control circuit, an alarm voice cue circuit and a connecting terminal block; Wherein, The liquid level signal output terminal of said underground liquid level meter is connected to the input end of analog signal of said A/D converter; The digital signal input end of said A/D converter is connected to the data capture input end of MCS52 single-chip microcomputer, and the control signal output terminal of said MCS52 single-chip microcomputer is connected to the control signal input end of said digital delay controller; Said digital delay controller stops control circuit output actuating motor to said startup and plays machine shutdown control signal, and simultaneously, said digital delay controller starts alarm signal to said alarm voice cue circuit output; Said startup stops the contact of drawing of control circuit draws through said connecting terminal block, as with the interface of pumping unit electric control loop.
During practical implementation, its preferred version is as shown in Figure 2, and said digital delay controller adopts the TS23 type time relay, and said startup stops control circuit and adopts MY2NJ type auxiliary reclay, and said alarm voice cue circuit adopts the TY-6B type computerized speech plate that amplifies.The YG-DC12V switch power of in this circuit, selecting is a working power.Among Fig. 2; L1 is the delayed alarm tutorial light; L2 is the work run indicator; And 1 in the connecting terminal block, 2 external 220V ac power supplys, and 3,4 control signal output points that start or stop as motor of oil extractor, and 5,6 as function switch K1 automatically or the reseting controling signal output points.3,4 pin of tenminal block and 5,6 pin should with 3,4 pin and the corresponding connection of 5,6 pin of function switch K1.J shown in the figure is the ac contactor coil in the former electric control circuit of motor of oil extractor; J1 is a pair of auxiliary normally opened contact of A.C. contactor for this reason then; This intermittently controller work when function switch K1 gets to 5,6 connections, former HA and TA button are inoperative; Get at 3,4 when connecting, this intermittently starter do not work.HA and TA button are startup and the stop buttons that is positioned on the pumping unit electric control box among Fig. 2.
This kind intermittently starter can realize starting according to the situation of actual load under the pumping well, have better practicability.
