Description

Technical Field

[0001] The utility model relates to the field of sucker rod detection equipment, in particular to a carbon fiber sucker rod water immersion ultrasonic detection device. Background Art

[0002] Rod pumping is the most widely used mechanical oil production technology at home and abroad. Due to the influence of factors such as well depth and the quality of steel sucker rods, the efficiency of mechanical oil production is greatly reduced. The number of accidents caused by the insufficiency of the sucker rods themselves accounts for 60%-70% of the accidents in oil wells. In addition, the traditional metal sucker rods have become the "bottleneck" restricting the development and growth of this oil production method due to their own shortcomings such as heavy weight, easy corrosion, and poor fatigue performance. Carbon fiber sucker rods have the characteristics of light weight, high strength, high rigidity, high temperature resistance, corrosion resistance, wear resistance, and integrated structure and function, which greatly improves the efficiency of oil production and greatly reduces the accident rate compared with traditional sucker rods.

[0003] For defects in carbon fiber composite materials during manufacturing and damage during use, domestic non-destructive testing is mainly carried out using technologies such as ultrasound, X-rays, and thermal infrared waves. Since manual ultrasonic flaw detection has many human uncertainties, product quality cannot be guaranteed, and water immersion automatic flaw detection is required to meet users' needs for the location, size, and distribution of defects inside the sucker rod.

[0004] The water immersion ultrasonic process requires the object to be tested to be placed in water. Due to the long length of the sucker rod, a longer water tank is required for testing the sucker rod. The water tank is overall long and occupies a large area. It needs to be lifted by lifting equipment during transfer and storage. When in use, it needs to be filled with a large amount of water, which leads to a long preparation time and affects the detection efficiency. Utility Model Content
