Ultra-low speed big torsional moment special-shape motor dragging and tower type high-efficiency low-consumption intelligent pumping unit

Abstract

The invention discloses an actuating tower type pumping unit of a low-velocity big-torque special-shaped motor, which is characterized by comprising a tower cylinder fixed on a cement basement, a digital intelligent control cabinet, a special-shaped motor on the top platform of the tower cylinder, a load hoisting belt wound round the roller of the special-shaped motor, and a balance box connected with the load hoisting belt. One end of the load hoisting belt is fixedly provided with a hanging rope or a hanging unit, while the other end of the load hoisting belt is connected with the balance box. The load hoisting belt is driven by the special-shaped motor to transmit torque forwardly and reversely. The rotating speed, the steering and the torque of the special-shaped motor are regulated and controlled by the digital intelligent control cabinet. The forward and reverse rotation of the special-shaped motor is converted to the reciprocating linear motion of a sucker rod so as to realize the oil pumping cycle of the pumping unit. The pumping unit is simple in structure and the intelligent controller thereof can be controlled automatically, manually or remotely. Thus, the perfect combination of high intelligence and fool-style operation is realized. The pumping unit is only provided with two lubricating points and can be operated for years without being lubricated. No easily damaged part is adopted by the whole pumping unit, while the pumping unit is time-saving and labor-saving in transportation, installation, use and maintenance.

Description

Technical field: [0001] The present invention is an ultra-low-speed, high-torque special-shaped motor-driven tower-type high-efficiency, low-consumption intelligent pumping unit. Torque special-shaped motor drives high-efficiency and low-consumption intelligent pumping unit" (ZL 02 2 57259.7), which is improved and innovated on the basis of the classic four-link beam pumping unit and the improved beamless pumping unit oil production process The revolutionary breakthrough is a new field of mechatronics application. Background technique: [0002] The original oil extraction activity of human beings is "pumping oil", and then the wooden pumping unit was invented. With the prolongation of the oilfield development period, the oil wells will eventually be transferred to the mechanical oil recovery method, and the original oil recovery technology is far from meeting the human demand for petroleum energy. It has a history of 120 years since the birth of Lufkin's first four-link be...

Problems solved by technology

With the development of high technology and the needs of oil extraction technology, the requirements for large load, long stroke and low stroke frequency models are becoming more and more urgent, and energy shortage and investment constraints are increasingly restricting the models with high energy consumption and low efficiency , but limited by the structure of the beam machine, the stroke length increases in direct proportion to the torque of the gearbox, making it difficult to achieve the requirements of high efficiency and low consumption

Under the determined working system, the beam traveling machine cannot randomly change the working parameters, and it takes time and effort to adjust the shutdown, which makes it difficult to dynamically coordinate the working system with the liquid supply capacity of the formation, resulting in low efficiency of the beam traveling machine system, large impact load, and failure of the machine rod pump There are many, it is urgent to develop a brand-new pumping unit that is better than the current types of pumping units to replace the existing models
