Abstract

The invention discloses an energy-saving pumping unit in a T-shaped walking beam structure. The invention is formed as follows: a walking beam is arranged on a support; one end of the walking beam is connected with a horse head; the other end of the walking beam is provided with a back balance heavy box; the back balance heavy box is connected with a lower walking beam arranged on the walking beam through a back link; the other end of the lower walking beam is provided with a lower balance heavy box; the middle of the lower walking beam is connected with a crank through a connection seat, a connecting rod and a crankpin; the crank is connected with a gearwheel through a gearwheel bearing; the gearwheel is joggled with a pinion and a retarder; the retarder is connected with an electromotor through a belt. With simple structure and rational design, the invention is a desirable oil field production equipment, and has remarkable energy-saving result.

Description

Technical field [0001] The invention relates to a beam pumping unit used in oil field development, in particular to an energy-saving pumping unit with a T-shaped beam structure, which is widely used in the production of crude oil in oil fields. technical background [0002] At present, the beam pumping unit used in the mine is mainly composed of beams, connecting rods, reducers, and balance blocks. It has a large starting power and poor balance. Energy-saving effect, but the effect is poor. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an energy-saving pumping unit with a T-shaped beam structure with remarkable energy-saving effect, which can adopt a low-power motor transmission system, thereby achieving the purpose of energy saving. [0004] The technical scheme adopted by the present invention to solve the technical problem is: install the beam on the bracket, one end of the beam is connected wi...
