Variable-torque balancer for pumping unit manufactured by high-end equipment

Abstract

The invention provides a variable-torque balancer for a pumping unit manufactured by high-end equipment, relates to the technical field of balancers, aims to solve the problems that when an existing pumping unit balancer is used, an adjusting structure is not convenient enough, variable torque cannot be conveniently guided, and convenient control and adjustment cannot be carried out in the using process. The variable-torque balancer comprises a main body, a guide groove, a moving part and a fixed part, wherein the main body is of a rectangular structure, a shaft hole is formed in the middle ofthe bottom of the main body, and two electric cylinders are arranged at two sides of the left end of the main body separately; and the top end of the moving part is mounted in a guide groove. The guide groove is used for mounting the moving part, after the moving part is connected with a power machine, a rotating part of the moving part can move in the guide groove, and a guide part can move in atop groove, so that the moving part can be guided to move to a proper position to be adjusted, and the pumping unit can carry out variable-torque balance adjustment.

Description

technical field [0001] The invention belongs to the technical field of balancers, and more specifically relates to a torque-conversion balancer for pumping units manufactured in high-end equipment. Background technique [0002] The pumping unit is one of the main equipments for pumping crude oil in the petroleum industry. At present, more than 80% of the ground mechanical oil extraction equipment commonly used in various countries in the world adopts the crank-balanced beam pumping unit, and the crank-balanced beam pumping unit The method of adjusting the balance moment is to rely on the balance weight that moves on the crank. [0003] For example, the application number: CN201210378596.X relates to the electric balancer of the beam pumping unit, which consists of a balance weight, a balance beam and a telescopic rod. , there are multiple hinged holes on the balance weight, and the other end is hinged with the balance beam. In the middle of the telescopic rod, there is a sc...
