Description

Technical Field

[0001] The present invention relates to the technical field of pumping units, and specifically to a petroleum hydraulic pumping unit. Background Art

[0002] A pumping unit is a machine device for oil extraction, commonly known as a "nodding donkey". A pumping unit is the most important lifting equipment in a rod pumping system. According to whether there is a walking beam, it can be divided into a beam pumping unit and a beamless pumping unit.

[0003] At present, the existing hydraulic pumping units on the market have some obvious disadvantages in the actual use process, which limit their performance in terms of working efficiency, stability and service life.

[0004] The existing hydraulic pumping units may lack effective reinforcement measures. The structural strength of key components such as support rods is insufficient, and it is difficult to withstand the large loads generated by the rapid swinging of the rocker arm and the swing head, resulting in the equipment being prone to shaking or even damage during operation, affecting its stability and service life. Moreover, due to the limitation of structural strength, the maximum work capacity and efficiency of the equipment cannot be effectively improved; the traditional hydraulic pumping unit adopts single-side drive, which will cause uneven stress on one side during the swinging process of the rocker arm, resulting in stress concentration inside the structure, not only causing greater pressure on the internal structure of the equipment, affecting the stability of the equipment, but also shortening the service life of the equipment; the existing hydraulic pumping units may not be able to flexibly adjust the swinging amplitude of the rocker arm and the liquid pumping efficiency according to the actual use requirements, and it is difficult for the staff to change the working parameters of the equipment through simple operations, making the equipment less adaptable to different working conditions and unable to meet the diverse production requirements.

[0005] In view of these deficiencies of the existing hydraulic pumping units in terms of structural strength, drive system, transmission process and operation flexibility, it is particularly necessary to design a "petroleum hydraulic pumping unit". The newly designed pumping unit can effectively solve the above problems, improve the stability, working efficiency and service life of the equipment, and at the same time enhance its operation flexibility and adaptability to meet the actual needs in the process of oil extraction.

At this time, the start and use of the device are completed; When it is necessary to adjust the length of the swing assembly 31, the staff only needs to start the double-shaft motor 3301. The start of the double-shaft motor 3301 drives the upper and lower threaded rods 3302 to rotate. The rotation of the threaded rods 3302 drives the upper and lower first connecting arms 3104 and the second connecting arms 3105 to move upward or inward synchronously. During the inward movement of the first connecting arm 3104 and the second connecting arm 3105, the length decreases, and the swing amplitude of the rocker arm 1204 is increased by cooperating with the sliding slider 3101. During the outward movement of the first connecting arm 3104 and the second connecting arm 3105, the length increases, and the swing amplitude of the rocker arm 1204 is decreased by cooperating with the sliding slider 3101.
