Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0023] refer to Figure 1-4 , a hydraulic transmission reciprocating oil extraction pumping unit, comprising a base 1, the upper end of the base 1 is equipped with a support 2, the upper end of the support 2 is slidably provided with a steel wire rope 3, wherein the steel wire rope 3 is slidingly connected with the guide wheel at the upper end of the support 2, And when the wire rope 3 is stretched, it is easy to generate heat due to friction. The upper end of the base 1 is fixedly connected with a box body 4, and the top surface of the box body 4 is connected to the cooling mechanism. The air outlet end of the cooling mechanism is located above the support 2. The to...

The invention relates to the technical field of petroleum exploitation, in particular to a hydraulically driven reciprocating pumping unit for petroleum exploitation, which can effectively cool down and dissipate heat at the friction between the steel wire rope and the bracket through the provided drive motor, air suction mechanism and cooling mechanism, and can also Cool and dissipate the connection between the steel wire rope and the first fixed pulley and the second fixed pulley, which can effectively improve the heat dissipation and cooling effect of the steel wire rope during use, which is beneficial to reduce the influence of frictional heat generation on the steel wire rope, and ensure the safety of the steel wire rope in use The height of the hydraulic cylinder in the box can be adjusted through the set lifting mechanism, suction mechanism, second transmission mechanism and first transmission mechanism, and then the height of the end of the wire rope can be adjusted, which is convenient for matching with the wire rope. The height of the oil pumping device fixedly connected at the end can be adjusted, which is beneficial to realize the driving and pumping of oil pumping devices with different installation heights, and improves the use range and convenience of the oil pumping unit.
Description
technical field [0001] The invention relates to the technical field of oil exploitation, in particular to a hydraulically driven reciprocating oil extraction pumping unit. Background technique [0002] Oil engineering is a general term for various engineering and technical measures taken to the reservoir through production wells and injection wells according to the development objectives in the process of oilfield exploitation. As a comprehensive applied discipline, it studies the theory, engineering design method and implementation technology of various engineering technical measures that can be economically and effectively applied to oil reservoirs to improve oil well production and crude oil recovery. [0003] When the hydraulically driven reciprocating oil extraction pumping unit in the prior art is in use, due to the friction between the wire rope and the guide wheel on the support, heat is generated during the friction process, and the friction point cannot be effectiv...
