Abstract

The invention relates to the technical field of oil pumping unit intelligent control, in particular to an automatic stroke number setting vertical oil pumping unit and an automatic stroke setting control method of the oil pumping unit. The automatic stroke setting vertical oil pumping unit comprises a tower frame, a chain wheel, a winch wheel, a crown sheave, a connecting rope, a connecting chain,an oil pumping rope, a rope hanger, a first rope chain connecting piece, a second rope chain connecting piece, an intelligent control module and a driving device, wherein the bottom of the tower frame is provided with the driving device; and the output end of the driving device is fixedly provided with the chain wheel. The automatic stroke number setting control method comprises the steps that the control module controls the rotation direction, the rotation speed and start or stop of a hydraulic motor, and the control module controls the flow, pumped into the hydraulic motor, of a hydraulic station. According to the automatic stroke number setting vertical oil pumping unit and the automatic stroke number setting control method of the oil pumping unit, the structure is reasonable and compact, the conception is ingenious, automatic stroke number setting is achieved through the cooperation of the intelligent control module and the driving device, and the characteristics of stability, high efficiency and intelligence are achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent control of pumping units, and relates to a vertical pumping unit with automatic stroke setting and a control method for automatically setting strokes of the pumping unit. Background technique [0002] Oilfield production personnel adjust the stroke times of the pumping unit according to the geological changes of the reservoir to maximize the output with the lowest energy consumption. Due to the difficulty of real-time measurement of reservoir geological conditions and the limited selection range of stroke times of traditional pumping units, the setting of stroke times for pumping units cannot always be optimal. On the other hand, due to the heavy workload of adjusting the stroke times of the pumping unit, it is impossible to adjust the stroke times of the pumping unit in time in actual production operations. Contents of the invention [0003] The present invention provides a vertical pumpin...
