Abstract
The utility model relates to a mechanical balancing adjustment device for an oil extractor in a mechanical oil production system, belonging to a mechanical oil production device. The utility model is composed of a machine frame, a walking beam, a balance weight block, a connecting rod, a reduction box, an electric motor, and an electric box, wherein, the upper side of the walking beam of the oil extractor is fixed with a regulating box; the inner part of the regulating box is provided with a balancer which is composed of a reversible electric motor, a screw rod which is driven by the reduction box, and a movable weight block which is arranged on the screw rod. According to the load power of an oil production machine, under the condition of no stopping, the position of the movable weight block can be regulated conveniently, and the effect of electric energy saving is achieved.
Description
The utility model belongs to oil recovery machiner Equilibrator class.
In the exploitation of petroleum industry, still be extensive use of shuttle pumping unit at present, be commonly called as the machine of kowtowing.Its main structure is made up of frame, walking beam, counterweight block, connecting rod, speed reducer, motor, electric control box.To-and-fro motion by pumping unit, underground crude oil is extracted on the ground, in order to make power motor operation balance, make its power reach minimum degree, on above-mentioned existing pumping unit, be provided with the counterweight block of adjustable eccentric degree, in the process of oil pumping, look the resistance situation of oil well down-hole and to the influence of motor load, should be at any time by the position of actual conditions adjustment pouring weight.But present pumping unit also has certain deficiency in the adjusting to counterweight block, need to stop to adjust, and what influence was produced normally carries out, adjusted position fixedly be fixing by toothed projections, do not have continuity, the labor intensity of adjusting is bigger.
The purpose of this utility model is: provide that can to carry out the balance adjustment in a kind of working procedure and adjust be the balance of machinery controlling device of continuous, level and smooth pumping unit.
Technical measures of the present utility model are: based on the pumping unit of being made up of frame, walking beam, counterweight block, connecting rod, speed reducer, motor, electric control box, on the walking beam of pumping unit, be fixed with a regulating box, the leading screw that is driven by reversible electric machine and speed reducer, the balance regulator that the mobile pouring weight on the leading screw is formed are housed in regulating box.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a tandem-driving bogie profile in elevation of the present utility model.
Fig. 3 is a tandem-driving bogie profile in plan of the present utility model.
Drawing explanation and embodiment are described below: 1 is oil well among the figure; The 8th, frame; Back shaft 10 articulated walking beams 2 on the frame; Walking beam 2 rear portions are hinged on the counterweight block 3 by connecting rod 4; The 5th, speed reducer; The 6th, motor; The 7th, electric control box, the rotation of motor 6 makes the walking beam swing lift wire rope and oil pump proposes ground with crude oil from oil well.Above-mentioned existing pumping unit, in the process of oil pumping according to the resistance situation of oil well down-hole and to the influence of motor load, at any time the position of adjustment pouring weight 3, need stop to the adjusting of pouring weight 3 positions and to adjust, what influence was produced normally carries out, adjusted position fixedly be fixing by toothed projections, do not have continuity, and the labor intensity of regulating is also bigger.In order to address the above problem, the utility model is equipped with a regulating box 9 on walking beam 2, and the leading screw 12 that is driven by reversible electric machine 14, speed reducer 13, the balance regulator that the mobile pouring weight 11 on the leading screw 12 is formed are housed in regulating box 9.15 is limit switches among the figure, the 16th, and fixed hole, the 17th, pouring weight 11 following guide wheels by dress.
In the running of pumping unit, according to the load condition of motor 6, change the position of mobile pouring weight 11 very easily by starting reversible electric machine 14, make the load power of motor 6 reach minimum degree, can reach tangible power savings.If be connected with a signal output device 19 with motor 6, make reversible electric machine under the indication of signal, rotate the position of regulating pouring weight 11 automatically by controller 18 again, the operation of so just can not choosing, but carried out balance adjustment automatically.For the pumping unit of coming of new, also can be with the walking beam 2 of pumping unit as regulating box, the leading screw that reversible electric machine and speed reducer are driven, the mobile pouring weight on the leading screw are installed in the walking beam 2.
Claims (2)
1. the balance of machinery controlling device of pumping unit is that frame, walking beam, counterweight block, connecting rod, speed reducer, motor, electric control box are formed in the mechanical oil production system, it is characterized in that: on the walking beam of pumping unit, be fixed with a regulating box, the leading screw that is driven by reversible electric machine and speed reducer, the Equilibrator that the mobile pouring weight on the leading screw is formed are housed in regulating box.
2. by the described controlling device of claim 1, it is characterized in that: can be with the walking beam of pumping unit as regulating box, the leading screw that reversible electric machine and speed reducer are driven, the mobile pouring weight on the leading screw are installed in the walking beam.
