Problems solved by technology

However, the device uses eddy current pulse signals, which are essentially different from the principle of magnetic flux leakage defect detection. The object of eddy current detection is mainly surface defects, and it is almost impossible to detect internal defects of elbows, and the patent does not involve tracking and processing of defects.

Abstract

The invention discloses an oil field fracturing elbow defect detection device and a test method. The detection device comprises a motor, a gear transmission pair, a detection platform, a fixed platform, a mobile slide block, a Hall element and a magnetizing coil. Specifically, the gear transmission pair includes a driving transmission part and a driven transmission part, the driving transmission part is mounted on an output shaft of the motor, the motor is fixed on the detection platform, the detection platform, the fixed platform and the driven transmission part center are hinged together, and one driven transmission part side close to the fixed platform is fixed on the fixed platform. The magnetizing coil is sleeved on the periphery of the Hall element, and the two are mounted inside Hall element fixing rings. One end of the mobile slide block is sleeved on the detection platform, and can slide freely along the detection platform, and the other end of the mobile slide block is hinged to the outside of the Hall element fixing rings. During test, the Hall element is sleeved on a to-be-detected elbow.

Description

Technical field: [0001] The invention relates to the field of an elbow defect inspection method and a detection device, in particular to an oil field fracturing elbow defect detection device and inspection method. Background technique: [0002] During oil field fracturing construction, fracturing fluid passes through fracturing vehicles and various connecting pipelines, and is finally applied in oil wells. Among them, elbows are widely used in pipelines, and their function is to change the direction of fluid to meet the requirements of on-site fracturing construction. Since the pressure of the fracturing fluid in the elbow is very high, up to about 100MPa, and contains corrosive media, it has a serious erosion effect on the inner and outer walls of the elbow (generally, the outer wall is more severely eroded), In the weak area of ​​elbow performance, defects such as cracks are prone to occur, and then rupture failure occurs, causing casualties and property losses. Therefor...
