Abstract

The invention provides a direct driving type poly cycle multiple-well oil pumping unit which comprises a master bracket, branch brackets, a soft rope, a polished rod eye, a low-speed large torque counter-rotating frequency modulation motor, a speed reducer, a dynamic roller wheel on the mater bracket, a balancing weight, a suspending weight roller wheel on the master bracket, dynamic roller wheels on the branch brackets, and suspending weight roller wheels on the branch brackets. The power is transferred to each branch bracket through the soft rope, the frequency modulation motor is provided to directly drive the swing in positive and negative directions for oil pumping, the suspending weight of each pumping unit is used for mutual balance, and one oil pumping unit can carry out oil extraction for a plurality of pumping units simultaneously, thus achieving the aim of saving energy.

Description

technical field [0001] The invention belongs to the field of pumping units in oil production machinery, in particular to a direct-drive multi-stroke multi-well pumping unit. Background technique [0002] At present, many oil wells are concentrated in one place in each oil field, and each oil well has a pumping unit for oil production, which increases investment and energy consumption, and also makes the structure of the equipment more complicated. Contents of the invention [0003] The purpose of the present invention is to overcome the difficult problems of the existing pumping unit technology, to meet the energy-saving requirements of the pumping unit, and to use the direct-drive multi-stroke multi-well pumping unit for oil production, so as to reduce the weight of the existing pumping unit and reduce the weight of the existing pumping unit. The purpose of reducing the working power consumption of the pumping unit. [0004] The purpose of the present invention is achiev...
