Abstract
The invention relates to the technical field of oil pumping unit intelligent control, in particular to a fault self-diagnosis vertical oil pumping unit and an oil pumping unit fault self-diagnosis control method. The fault self-diagnosis vertical oil pumping unit comprises a tower, a chain wheel, a reel, a head sheave, a connecting rope, a connecting chain, an oil pumping rope, a beam hanger, a first rope chain connecting piece, a second rope chain connecting piece, an intelligent control module and a driving device; and the driving device is arranged at the bottom of the tower, and the chainwheel is fixedly mounted at the output end of the driving device. The oil pumping unit fault self-diagnosis control method comprises the steps that the control module controls the rotating direction,the rotating speed, starting and stopping of a hydraulic motor, and the control module controls the flow pumped into the hydraulic motor by a hydraulic station. The fault self-diagnosis vertical oil pumping unit is reasonable and compact in structure and ingenious in concept, through cooperation of the intelligent control module and the driving device, oil pumping unit fault self-diagnosis is achieved, 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 fault self-diagnosis vertical pumping unit and a fault self-diagnosis control method for the pumping unit. Background technique [0002] During the operation of the pumping unit, the sucker rod will break off or stick. Since the sucker rod is running underground, the failure phenomenon is often not found at the first time, resulting in damage to the equipment and loss of production. . Contents of the invention [0003] The invention provides a fault self-diagnosis vertical pumping unit and a fault self-diagnosis control method of the pumping unit, which overcomes the above-mentioned deficiencies in the prior art and can effectively solve the problem that the existing pumping unit cannot realize fault self-diagnosis. [0004] One of the technical solutions of the present invention is achieved through the following measures: a vertical oil pumping un...
