Abstract

The invention relates to the technical field of intelligent control of oil pumping units and provides a vertical oil pumping unit capable of achieving automatic stepless speed regulation and an automatic stepless speed regulation control method of the oil pumping unit. The vertical oil pumping unit comprises a tower frame, a chain wheel, a reel, a head sheave, connection ropes, connection chains,oil pumping ropes, rope hangers, 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 atthe bottom of the tower frame; the chain wheel is fixedly mounted at the output end of the driving device. The automatic stepless speed regulation control method of the oil pumping unit comprises thefollowing steps: controlling a rotating direction and a rotating speed of a hydraulic motor through a control module, starting and stopping; and controlling flow pumped into the hydraulic motor by a hydraulic pressure station through the control module. The vertical oil pumping unit is reasonable and compact in structure and ingenious in design; through cooperation between the intelligent controlmodule and the driving device, automatic stepless speed regulation of the oil pumping unit is achieved; and the vertical oil pumping unit has the characteristics of stability, high efficiency and intellectualization.

Description

technical field [0001] The invention relates to the technical field of intelligent control of pumping units, and relates to an automatic stepless speed regulation vertical pumping unit and an automatic stepless speed regulation 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. [0003] The pumping unit stroke is one of the important adjustment parameters in the production and...
