Balance adjustment device for pumping units

Abstract

The invention discloses a balance adjustment device for pumping units. The balance adjustment device comprises a rack, a steel channel, a balance box, a reducer, an electromagnetic brake motor, a reducer output shaft gear, a control cabinet and a beam arm. The rack is disposed on the steel channel. The balance box is disposed inside the steel channel. A body of the balance adjustment device is fixed on the beam arm. The reducer output shaft gear meshes with the rack. The balance box is connected with a control cabinet. The electromagnetic brake motor is connected with the reducer output shaft gear. The electromagnetic brake motor and the reducer output shaft gear are disposed inside the balance box. The motor and the balance box are integrated; balance torque change curves are maximally fitted with load torque curves by changing the balance force of arm of the balance box; the pumping unit is relatively balanced. The balance adjustment device is simple in structure, high in intelligence level, good in safety and stability, wide in application range and high in balance adjustment precision and allows the balance of the pumping unit to be adjusted safely and accurately.

Description

technical field [0001] The invention belongs to the technical field of oilfield equipment, and in particular relates to a balance adjustment device for a pumping unit. Background technique [0002] In the process of oil field production management, because the balance of the pumping unit is closely related to the actual energy consumption and service life, the balance of the pumping unit is an important and frequent work. Manually balance the beam pumping unit Diagnosis and adjustment will be interfered by subjective factors, resulting in low adjustment accuracy, and balance adjustment is labor-intensive, low-efficiency, and low-safety. In addition, some pumping units have been unable to perform balance adjustment through their own balance devices. Therefore, in recent more than ten years, various pumping unit adjusting balance devices and tools have been developed one after another. [0003] But so far, there is no relatively highly integrated device in China that can auto...
