Automatic balance-adjusting beam-pumping unit and method

Abstract

The invention discloses an automatic balance-adjusting beam-pumping unit and an automatic balance-adjusting method. An automatic balance-adjusting device is arranged on a crank of a pumping unit; the automatic balance-adjusting device comprises a fixed balance block, a left movable balance block, a right movable balance block, a balance motor and a right-angle speed reducer, wherein the fixed balance block is connected with the crank through a bolt, and the fixed balance block can slide on the crank in the length direction of the crank; the right-angle speed reducer is connected with the balance motor, and the right-angle speed reducer is mounted on the fixed balance block; output shafts are arranged on the two side surfaces of the right-angle speed reducer, and have opposite rotating directions; the left movable balance block and the right movable balance block are mounted on the output shafts on the two side surfaces of the right-angle speed reducer respectively. The balance motor is started up, the balance motor transmits power to the right-angle speed reducer, the right-angle speed reducer drives the left movable balance block and the right movable balance block to rotate, and the balance of the beam-pumping unit is adjusted by changing the gravity center positions of the left movable balance block and the right movable balance block.

Description

technical field [0001] The invention relates to the technology of a beam pumping unit, in particular to an automatic balancing beam pumping unit and a method thereof. Background technique [0002] At present, the rod pump pumping equipment commonly used in the oil field is the beam pumping unit. In order to reduce the force on the driving parts of the pumping unit and reduce the torque of the reducer and the power of the motor, it is necessary to add a balance block on the crank or beam to Balance well load. Because the oil well load changes frequently, the balance block needs to be adjusted in time. The existing beam pumping unit is basically adjusted manually, which has problems such as untimely adjustment, long adjustment time, and heavy adjustment workload. Contents of the invention [0003] The purpose of the present invention is to provide an automatic balance beam pumping unit and method, which can realize the automatic balance adjustment of the pumping unit, which...
