Abstract

The invention discloses a walking beam oil pumping unit connected with a single connecting rod structure on an adjustable balance-type crank, which is formed by the steps that: a walking beam is mounted on an integrally manufactured bracket via a central bearing assembly, one end of the walking beam is connected with a horse head, the tail of the other end of the walking beam is designed with a crank having a regulating gear through a bearing assembly on the end part of the walking beam, one end of the crank is connected with a balancing weight via the regulating gear and the other end of the crank is connected with one end of the connecting rod through the bearing assembly of the crank, the other end of the connecting rod is connected with an open big gear wheel via a connecting head, the open big gear wheel is connected with a decelerator, and the decelerator is connected with a motor through a belt. The invention is simple in structure, reasonable in design, outstanding in energy-saving effect and is an ideal oil field production apparatus.

Description

Technical field [0001] The invention relates to a beam pumping unit used in oilfield development, in particular to a beam pumping unit with an adjustable and balanced crank connected with a single connecting rod structure, which is widely used in the production of crude oil in the oil field. technical background [0002] At present, the beam pumping unit used in the mine is mainly composed of beams, connecting rods, reducers, and balance weights. It has a large starting power and poor balance. The improved beam pumping unit has been developed. Energy-saving effect, but the effect is poor. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present invention provides a beam pumping unit with a single-link structure connected to an adjustable and balanced crank with significant energy-saving effect. It can adopt a low-power motor transmission system to achieve the purpose of energy saving. . [0004] The technical solution adopted by the p...
