Embodiment Construction

[0025] exist figure 2 Among the embodiments: 1. is the upper platform of the pumping unit, which is welded with section steel, and the upper platform 1 is the base of the fixed pulley 2, and it is installed on the frame 4. The frame 4 is the carrier of the pumping unit, made of section steel, and it is installed on the concrete foundation 12. The 2nd, fixed pulley, fixed pulley utilizes MC to make, and fixed pulley seat utilizes cast steel to make. image 3It is a structural diagram of the motor 10, and the motor is designed as a rare-earth permanent magnet synchronous motor with low speed and high torque of the outer rotor. The motor 10 is installed on the concrete foundation 12, and traction wheels are arranged on both sides of the motor 10 for power transmission by flexible cables. A brake system 11 is installed on the outer edge of the outer rotor of the motor 10 . The power of motor 10 is transmitted by wire rope 5, fixed pulley 2. 3 is the M-type traction system. Th...

Abstract

An M-shaped tractive digitalized energy-saving oil pumping unit is composed of a unit frame, an upper platform, a motor, a braking system, a traction system, a counterweight system, a control system, a polished rod breaking emergency safety mechanism and a folding yielding mechanism. The motor is a rare-earth permanent magnet synchronous motor with an outer rotor, low rotation speed and high torque, traction wheels are coaxial with the motor and arranged on two sides of the motor, a steel wire rope is wound in an M-shaped mode and serves as the traction system, the reciprocating motion of the oil pumping unit is achieved through forward and reverse rotation of the motor, the forward and reverse rotation and the running speed of the motor are controlled by the control system through digitalized program, the braking system is arranged on the outer edge of the outer rotor of the motor, the polished rod breaking emergency safety mechanism is arranged in a counterweight box, and the folding yielding mechanism is arranged on the front side of the upper platform and is folded by using a hand-held winch during well repair so as to reserve an operation space for a well repair machine without machine moving. The M-shaped tractive digitalized energy-saving oil pumping unit saves energy and is safe and reliable.

Description

technical field [0001] The invention relates to a pumping unit in oilfield petroleum machinery, in particular to an energy-saving pumping unit in petroleum oil recovery machinery. Background technique [0002] Known pumping unit has beam pumping unit and beam pumping unit without beam at present. The former is a traditional pumping unit, which has been used for more than 100 years and has the advantages of being durable. However, the large horse-drawn trolley has a long transmission path, low mechanical efficiency, high energy consumption, and difficult parameter adjustment. It is not suitable for long-stroke and low-stroke occasions. The latter is the beamless pumping unit developed successively by relevant R&D personnel in combination with the actual situation of the oil field in the past ten years. At present, there is a W-type traction pumping unit (patent number: 200920154910X) on the market. This pumping unit has long strokes and low stroke times, and is suitable for ...
