Abstract

The present invention relates to an oil pumping machine used in oil field, in particular to an energy-saving beam oil pumping machine, which solves the problem that the prior beam oil pumping machine is difficult to achieve the energy saving due to the restrictions of the work principle and structure, in particular to the limited realization of operating mechanism. The present invention includes a central bracket, a beam, an oil pumping rod and a crank fixed with a balanced block on one end and driven by a motor and a reducer. One end of the beam is provided with a donkey head and the other end is connected with the crank through a connecting rod; an energy storage and utilization device is arranged below the upper beam of the central bracket; the energy storage and utilization device includes a support fixed body arranged on the central bracket, a support rod supported by the support fixed body reciprocating along a fixed direction against the support fixed body, a regulating jacket fixed on the support rod and a spring arranged between the regulating jacket and the fixed body on the support rod. The present invention with simple and reasonable structure and good energy-saving effect is suitable for all balanced beam oil pumping machines.

Description

technical field [0001] The invention relates to an oil pumping machine used in an oil field, in particular to a beam-type energy-saving pumping machine. Background technique [0002] The existing beam pumping unit comprises a central support, a beam arranged on the top of the central support, an oil pump rod, and a crank with a balance weight fixed at one end driven by a motor and a reducer. The cable is connected to the donkey head of the oil pump rod, and the other end is connected to the crank through the connecting rod. Driven by the motor and the reducer, the crank drives the balance block to run continuously, drives the beam to reciprocate up and down with the top of the central bracket as the center of rotation through the connecting rod, and then drives the oil well pump rod to reciprocate vertically up and down through the donkey head and the steel cable to realize Extraction of crude oil from deep formations. The general theory holds that the energy loss of the b...
