Abstract
The utility model discloses a multifunctional distribution box for an oil pumping unit, consisting of a box which is provided with an input post head of three-phase electricity, an air-break switch, an AC contactor and an output post head of the three-phase electricity in sequence, characterized in that the AC contactor is provided with an intermittent pumping control circuit, an automatic starting control circuit after electricity is given and a manual starting control circuit. The utility model has the power distribution functions of automatic intermittent pumping, automatic starting, manual starting, etc, and the function of delaying alarm before started, which is safe and is widely applied to the distribution box for the oil pumping unit used in the oil field.
Description
One, technical field
The utility model relates to the distribution box of oil pumper on the oil field.
Two, background technology
At present, the distribution box of oil pumper is made up of components and parts such as air switch, A.C. contactor and motor protecters on the oil field, manually controls oil pumper and stops and starting.Because the oil field area is big, far away, the dispersion of well spacing, when power-off condition takes place, the manual starting oil pumper is started shooting, and workload is big, and the time is long, influences oil recovery amount; In addition, now a lot of oil fields are in exploitation later stage, oilbearing stratum fuel feeding deficiency, oil pumper continuous operation, often be in idle aspiration phases, cause power wastage, equipment attrition is manually finished intermittent pumping, workload is big, is difficult to guarantee the rational intermittent time, also can influence oil recovery amount.
Three, summary of the invention
The purpose of this utility model provides can start oil pumper, the distribution box of intermittent pumping automatically after a kind of power failure automatically.
The utility model multifunctional oil-extractor distribution box, comprise a casing, be disposed with the output wiring terminal of lead-in clamp, air switch, A.C. contactor and the three-phase electricity of three-phase electricity in this casing, described A.C. contactor has starting switch, be characterized in: described A.C. contactor is provided with intermittent pumping control circuit, incoming call back start control circuit and manual starting control circuit automatically, and described intermittent pumping control circuit is composed in series successively by time controller, alarm, delay controller and intermittent pumping switch; Described incoming call back start control circuit automatically is made up of above-mentioned alarm, above-mentioned delay controller and automatic starting switch, automatically starting switch is a double acting switch, an one contact and described time controller parallel connection, another contact and intermittent pumping switch in parallel; Described manual starting control circuit is made up of manual starting switch, and above-mentioned intermittent pumping switch, automatic starting switch and manual starting switch can only be selected one and open.
In the such scheme, described intermittent pumping switch, automatic starting switch and manual starting switch can be made a knob, rotate different angles, realize switch motion.
The utility model has the advantages that: intermittent pumping, automatic starting, manual starting can be chosen one wantonly, and before starting the delayed alarm function are arranged, and be safe and reliable.Can control the operation of the different situation pumping unit of well in oil field better.
Four, description of drawings
Described in detail below in conjunction with the utility model embodiment accompanying drawing:
Fig. 1 is the utility model surface structure schematic diagram;
Fig. 2 is the utility model circuit working schematic diagram.
Five, embodiment
As depicted in figs. 1 and 2, the utility model multifunctional oil-extractor distribution box, comprise a casing 1, be disposed with the output wiring terminal 5 of lead-in clamp 2, air switch 3, A.C. contactor 4 and the three-phase electricity of three-phase electricity in this casing 1, A.C. contactor 4 has starting switch 6, be characterized in: A.C. contactor 4 is provided with intermittent pumping control circuit, incoming call back start control circuit and manual starting control circuit automatically, and described intermittent pumping control circuit is composed in series successively by time controller 7, alarm 8, delay controller 9 and intermittent pumping switch 10; Described incoming call back start control circuit automatically is made up of alarm 8, delay controller 9 and automatic starting switch 11, automatically starting switch is a double acting switch, an one contact 111 and time controller 7 parallel connections, another contact 112 and 10 parallel connections of intermittent pumping switch; Described manual starting control circuit is made up of manual starting switch 12.Intermittent pumping switch 10, automatic starting switch 11 and manual starting switch 12 are made a knob, rotate different angles, and the realization switch motion can only be selected one and open.When needs are adjusted into intermittent pumping, rotary knob, intermittent pumping switch 10 is connected, and starting switch 11 and manual starting switch 12 disconnect automatically, open starting switch 6 and get final product; When needs are adjusted into automatic starting oil pumping, rotary knob, starting switch 11 is connected automatically, and intermittent pumping switch 10 and manual starting switch 12 disconnect, and open starting switch 6 and get final product; When needs are adjusted into the manual starting oil pumping, rotary knob, manual starting switch 12 is connected, and intermittent pumping switch 10 and starting switch 11 disconnections are automatically opened starting switch 6 and are got final product.
Claims (2)
