The controller has the characteristics of reducing the mechanical wear of the oil pumping unit, saving energy and enhancing efficiency.

Description

The oil pumper intermittent controller

Technical field

The utility model relates to a kind of device that the oil field is used for oil pumper control field, specifically, relates to a kind of simple control device that can realize the control of oil pumper intermittent pumping.

Background technology

Domestic most oil field 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 oil pumper operate as normal exactly, causes to form that vacuum, load increase the weight of, mechanical wear is serious in the oil pumper pump housing and adverse consequences such as working current increase.Simultaneously,, cause the waste of the energy, make that the production cost of crude oil is improved greatly because extraction liquid reduces.

Summary of the invention

In order to solve problems of the prior art pointed in the background technology, the utility model provides a kind of oil pumper intermittent controller, this oil pumper intermittent controller can be realized control oil pumper intermittent pumping according to pre-set time interval, has the advantages that can reduce the oil pumper wearing and tearing, reduce energy resource consumption.

The technical solution of the utility model is: this kind oil pumper intermittent controller, comprise controller housing, in described housing, include a micro computer clock controller, a digital delay controller, a startup and stop control circuit, an alarm voice cue circuit and a connecting terminal block; Wherein, described micro computer clock controller is exported the startup time delayed signal that the digital delay controller is started working to described digital delay controller; Described digital delay controller stops control circuit output actuating motor to described startup and plays machine shutdown control signal, and simultaneously, described digital delay controller starts alerting signal to described alarm voice cue circuit output; Described startup stops the contact of drawing of control circuit draws by described connecting terminal block, as with the interface of oil pumper electric control loop.Described micro computer clock controller adopts CX-TGK01 type micro computer clock switch, described digital delay controller adopts the TS23 type time relay, described startup stops control circuit and adopts MY2NJ type auxiliary reclay, and described 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 oil pumper is directly realized connecting by terminal row, in addition, need not to remake change and just can realize control to the oil pumper intermittent pumping.Startup work that the user can be provided with this controller according to the oil offtake and the oil pumper running current situation of every mouthful of well and shutdown quiescent interval; after setting finishes; this controller can be controlled the operation of oil pumper automatically; need not the operating personnel guard; like this, all can acquisition section during the oil pumper each run to satisfy the needed production fluid amount of oil pumper operate as normal, avoided forming in the oil pumper pump housing problem of vacuum; save the energy simultaneously thereby reduce mechanical wear, reduced the production cost of crude oil.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

By shown in Figure 1, this kind oil pumper intermittent controller, comprise controller housing, in described housing, include a micro computer clock controller, a digital delay controller, a startup and stop control circuit, an alarm voice cue circuit and a connecting terminal block; Wherein, described micro computer clock controller is exported the startup time delayed signal that the digital delay controller is started working to described digital delay controller; Described digital delay controller stops control circuit output actuating motor to described startup and plays machine shutdown control signal, and simultaneously, described digital delay controller starts alerting signal to described alarm voice cue circuit output; Described startup stops the contact of drawing of control circuit draws by described connecting terminal block, as with the interface of oil pumper electric control loop.

During concrete enforcement, its preferred version as shown in Figure 2, described micro computer clock controller U1 adopts CX-TGK01 type micro computer clock switch, and described digital delay controller U2 adopts the TS23 type time relay, and the both has the automatically actuated function of switching on again after the outage.Described startup stops control circuit and adopts MY2NJ type auxiliary reclay, and described alarm voice cue circuit adopts the TY-6B type computerized speech plate that amplifies.The YG-DC12V Switching Power Supply of selecting in this circuit is a working power.Among Fig. 2, L1 is the delayed alarm pilot lamp, L2 is the work run indicator, and 1 in the connecting terminal block, 2 external 220V AC power, and 3,4 control signal output points that start or stop as motor of oil extractor, and 5, the 6 automatic or reseting controling signal output points as function switch K1.3,4 pin of connection terminal 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 controller do not work.HA and TA button are startup and the stop buttons that is positioned on the oil pumper electric cabinet among Fig. 2.

During use, the concrete course of work of this device is as follows:

After U1 and U2 configured the time, the 220V AC power inserted

connection terminal

1,2, when function switch K1 delivers to 1,2 pin of U1.Setting-up time arrives, and U1 starts working, and 3,4 pin have the output of 220V voltage, deliver to 2,7 pin of U2, the U2 delay working begins, and 1,2 pin of while U4 get electric, and Switching Power Supply is started working, 3,4 pin have the output of direct current 12V voltage, deliver to 1 pin of U5 through 4,6 pin of U3,2 pin are negative pole, U5 work, output alarm signal, time dalay indicator light L1 is bright.

The delay time of setting as U2 then, 1,3 pin of U2 are connected, 5,8 pin disconnect, 6,8 pin are connected, the L1 lamp extinguishes, and L2 is bright for the work run indicator, and meanwhile, 7,8 pin of U3 get electric work, 1,2 pin are connected, and 4,6 pin disconnect, and cut off the warning circuit power supply, and warning stops.Because this moment, 1,3 pin of U3 were connected,

connection terminal

3,4 is also connected, and goes to control the three-phase ac contactor adhesive in the former oil pumper electric cabinet, motor starting, and oil pumper is started working.

When the U1 setting-up time comes then, 3,4 pin do not have the output of 220V voltage, and controller enters intermittently state, and oil pumper also stops thereupon.Above process circulation is carried out, and has promptly realized the control at intermittence to oil pumping machine oil pumping.
