Problems solved by technology

Although this kind of manual braking solves the maintenance problem of the pumping unit to a certain extent, this type of braking device requires workers to operate beside the pumping unit, which has certain dangers. At the same time, the braking timing of this type of braking device requires workers. Judgment, it is difficult to precisely control the parking position
And in the process of on-site operation, there is a problem of locking failure in the brake locking block, which poses a big safety hazard
The hydraulic braking device modified on the basis of the traditional braking device has greatly improved the braking effect with its safe braking capacity, but the field equipment has changed a lot and the cost is high

Abstract

The invention discloses an intelligent braking system of an oil well pumping unit and a control method thereof, comprising an electrical control unit of the pumping unit, an intelligent braking control system, a power supply system and a braking auxiliary structure, the intelligent braking control system and the electrical control unit of the pumping unit are The integrated structure, the electric control unit of the pumping unit is connected with the pumping unit through the motor, the brake intelligent control system is connected with the pumping unit through the brake auxiliary structure, and the coordinated intelligent control of the operation of the pumping unit and the brake auxiliary structure is realized by modular connection. The invention provides a new design thought and method for the design of a safe, reliable and low-cost modified intelligent braking system of a pumping unit in the construction of a smart oil field.

Description

technical field [0001] The invention belongs to the technical field of oil production equipment in oil fields, and in particular relates to an intelligent braking system of an oil well pumping unit and a control method thereof. Background technique [0002] During oil field production, oil well pumping units need frequent maintenance, adjustment of stroke and stroke times, and switching of working conditions. The brake system is the core device for the safe operation of the pumping unit. It plays an important role in ensuring the safety of the operation and facilitating the installation and commissioning in the installation, commissioning, working condition adjustment and workover operations. The reliability of the brake system is not only related to whether the normal production of the oil field can go on smoothly, but also involves the personal safety of the operators and other issues. At present, the manual mechanical pull rod brake is widely used in oilfield production,...
