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 oil well pumping unit intelligent brake system and a control method thereof. The system comprises a pumping unit electrical control unit, a brake intelligent control system,a power supply system and a brake auxiliary structure. the brake intelligent control system and the pumping unit electrical control unit are of an integrated structure, the pumping unit electrical control unit is connected with a pumping unit through a motor, the brake intelligent control system is connected with the pumping unit through the brake auxiliary structure, and coordinated intelligentcontrol over operation of the pumping unit and the brake auxiliary structure is achieved through modular connection. The invention provides a new design thought and method for designing the pumping unit intelligent brake system which is safe, reliable and reconstructed at a low cost in intelligent oil field construction.

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 for oil well pumping units and a control method thereof. Background technique [0002] In the process of oilfield production, oil well pumping units need to be frequently maintained, adjusted strokes and strokes, and switched between 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 debugging in the installation, commissioning, working condition adjustment and well workover operations. The reliability of the braking system is not only related to whether the normal production of the oil field can be carried out smoothly, but also related to the personal safety of the operators. At present, artificial mechanical pull-rod brakes are commonly used in oilfield...
