Abstract

The invention relates to the technical field of intelligent control of pumping units, in particular to a full-intelligent vertical hydraulic pumping unit and a pumping unit control method. The full-intelligent vertical hydraulic pumping unit comprises a tower, a chain wheel, a reel, a hoisting sheave, a connecting rope, a connecting chain, a pumping rope, a polished rod eye, a rope slot ring, a first rope chain connecting part, a second rope chain connecting part, an intelligent control module and a driving device, wherein the driving device is arranged at the bottom of the tower, and the chain wheel is fixedly mounted at an output end of the driving device. The pumping unit control method comprises the following steps: the control module controls the rotating direction, the rotating speedand start and stop of a hydraulic motor; and the control module controls the flow of oil in a hydraulic station pumped into the hydraulic motor. The full-intelligent vertical hydraulic pumping unit is reasonable and compact in structure and skillful in concept. By matching the intelligent control module with the driving device, automatic stepless speed regulation, automatic setting of number of strokes and self diagnosis of operation of the pumping unit are achieved. By arranging the detachable and fixable rope slot ring, it is convenient to replace a rope slot which is worn. The full-intelligent vertical hydraulic pumping unit has the characteristics of being stable, efficient and intelligent.

Description

technical field [0001] The invention relates to the technical field of intelligent control of pumping units, and relates to a fully intelligent vertical hydraulic pumping unit and a control method for the pumping unit. Background technique [0002] The stroke frequency of the pumping unit is the most important adjustment parameter in the production and operation of the pumping unit. Existing pumping units mainly realize the adjustment of stroke times by changing the belt pulley and changing the transmission ratio of the system. Since the number of pulleys cannot be infinitely large, each pumping unit can only be adjusted at a few set strokes. At the same time, because the replacement of the pulley is manual work, frequent adjustments cannot be made, so the strokes of the existing pumping unit Stepless adjustment is not possible at this time. [0003] The pumping unit stroke is one of the important adjustment parameters in the production and operation of the pumping unit. ...
