Abstract
A hydraulic double-horsehead pumping unit is characterized in that: a hydraulic cylinder, a controller, a hydraulic pump and an oil tank which are connected through oil pipes are arranged on the chassis of the double-horsehead pumping unit; because the hydraulic cylinder is adopted to replace a four-bar power mechanism, the structure is simplified, the production cost is reduced, and the power consumption in operation can be reduced.
Description
Technical Field
The invention relates to a mechanical device in a mine field, in particular to a hydraulic double-horsehead pumping unit for an oil field pumping well.
Background
At present, the double-donkey pumping units adopted in each oil field are mostly four-connecting-rod power mechanisms, so that the problems of complex structure, high production cost, relatively large energy consumption and the like exist.
Disclosure of Invention
In order to overcome the problems of complex structure, high production cost, relatively large energy consumption and the like of the conventional double-horsehead pumping unit, the invention provides a hydraulic double-horsehead pumping unit which has simple structure and low production cost and can obviously reduce the consumption of electric energy because a hydraulic cylinder is adopted to replace a four-connecting-rod power mechanism.
The technical scheme adopted by the invention for solving the technical problems is as follows: a hydraulic cylinder, a controller, a hydraulic pump, an oil tank and the like which are connected through oil pipes are arranged on a double-horsehead pumping unit chassis without a four-connecting-rod power mechanism. The bottom of the hydraulic cylinder is arranged on the chassis of the double-horsehead oil pumping unit in a sitting mode, and the upper part of the hydraulic cylinder is connected with the walking beam; meanwhile, an oil pipe for providing power liquid of the hydraulic cylinder is connected with a controller arranged on the hydraulic pump, and an oil pipe for supplying the liquid to the hydraulic pump is connected with an oil tank.
The four-connecting-rod power mechanism has the advantages that the four-connecting-rod power mechanism of the double-horsehead pumping unit is replaced by the hydraulic cylinder, so that the structure is simplified, the production cost is reduced, and the power consumption in operation can be reduced.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural diagram of a hydraulic double-horsehead pumping unit.
In the figure, 1, a walking beam, 2, a double-horsehead pumping unit, 3, a hydraulic cylinder, 4, an oil pipe, 5, a hydraulic pump, 6, a controller and 7, an oil tank are arranged.
Detailed Description
In the figure 1, a hydraulic cylinder (3) is installed on a chassis of a double-horsehead pumping unit (2) without a four-link power mechanism, the bottom of the hydraulic cylinder (3) is seated on the chassis of the double-horsehead pumping unit (2), the upper part of the hydraulic cylinder is connected with a walking beam (1), an oil pipe (4) for providing power liquid of the hydraulic cylinder (3) is connected with a controller (6) installed on a hydraulic pump (5), and the oil pipe (4) for supplying the liquid to the hydraulic pump (5) is connected with an oil tank (7). When in operation, hydraulic oil in the oil tank (7) supplies liquid to the hydraulic pump (5) through the oil pipe (4), and power liquid output by the hydraulic pump (5) respectively supplies power liquid to the upper part and the lower part of a piston in the hydraulic cylinder (3) through the controller (6). When power liquid is supplied to the lower part of the piston in the hydraulic cylinder (3), the horse head at the hydraulic cylinder (3) end of the double-horse-head oil pumping unit (2) has an upper stroke; when power liquid is supplied to the upper part of the piston in the hydraulic cylinder (3), the horse head at the hydraulic cylinder (3) end of the double-horse-head oil pumping unit (2) is in a lower stroke; the stroke of the horse head can be realized by controlling the up-down stroke of the piston in the hydraulic cylinder (3), and the stroke number of the horse head can be realized by controlling the up-down stroke of the piston in the hydraulic cylinder (3).
