Abstract

The invention relates to a load simulation test device of an oil pumping unit. The device comprises a control system, a load simulation system, a slide damping platform and a load guide mechanism. Theload simulation mechanism provides a load through a servo motor and a magnetic powder brake, and a force-measuring sensor feeds back and adjusts the magnitude of the load. A damping force-measuring platform is provided with a mold spring and a linear slide rail assembly moving along a fixed guide rod so that the fluctuation generated by instantaneous impact in an equipment operating process is effectively reduced, and the accuracy and the sensitivity of control of the load by the system are improved. According to the digital load simulation test device of the oil pumping unit, through cooperation of a torque control mode of the servo motor and the magnetic powder brake, various oil pumping conditions can be simulated more accurately and conveniently.

Description

technical field [0001] The invention relates to a load simulation test device for an oil pumping unit, which belongs to the new field of electromechanical integration application. Background technique [0002] The pumping unit is the most important mechanical equipment in the process of oil exploitation, mainly including beam pumping unit and tower pumping unit. The beam pumping unit has become the most mature and widely used pumping unit due to its simple structure, convenient use, and ease of manufacture. Notable issues such as limited stroke distance. However, due to the balance between the sucker rod and the counterweight in the structure of the tower pumping unit, the process of storing and releasing potential energy is exchanged uninterruptedly with each other, which realizes the balance of movement, and can effectively solve the problem of low efficiency and difficulty in pumping machinery. Due to the problems of long stroke and high energy consumption, this type of...
