Description

An Intelligent Detection System for Sucker Rod

technical field

The utility model relates to the technical field of sucker rods for oil and gas development, in particular to an intelligent detection system for sucker rods.

Background technique

The sucker rod is one of the common parts in the oil field and an important part of the pumping unit. It connects the pump and the plunger to transmit power. Therefore, the mechanical properties of the sucker rod are very important to the quality of the product. The essential. With the increase of the service life of oilfield equipment, the wear and tear of the sucker rod occurs continuously, and the material, processing technology and shape parameters of the sucker rod will affect its life in actual use. Whether the shape and size of the rod body meets the specifications seriously affects the mechanical properties of the product. Therefore, the detection of shape and position errors is also an extremely important part of the quality detection of sucker rods.

With the development of my country's economy, the manufacturing level of sucker rod enterprises is also constantly improving, and some advanced processing enterprises in China have introduced a large number of automatic processing equipment. With the improvement of the domestic scientific and technological level, especially the rapid development of computer technology and detection technology, advanced detection methods have become possible. For example, the sucker rod flaw detection has already realized full automation. Moreover, the entire inspection process can be completed on the production line after a simple modification of the flaw detection equipment. On the one hand, automated and digital detection methods greatly improve the accuracy of detection, and on the other hand, they save manpower and material resources. At the same time, the digital detection results are stored in the computer and can be used as the basis for subsequent production process adjustments after analysis and research. Although automated inspection is of such importance in the processing industry, automated inspection has not completely replaced manual inspection methods.

Today, the shape and position errors of sucker rods still need to be detected manually. Quality inspectors operate gauges to judge whether the external dimensions of the sucker rod body are qualified. This traditional method is not only time-consuming and laborious, and is easy to cause damage to the rod body, but also has the following major defects in the detection principle: 1. The use of gauges to judge only It can detect whether the sucker rod is qualified, but cannot measure the specific numerical value of the shape and position error; 2. Since the detection process is manual measurement, and the operation is relatively difficult, it is relatively affected by subjective factors such as the worker's operating proficiency, work attitude, and emotion. 3. The detection method does not meet the relevant standards, or even the relevant definition of shape and position error; 4. Due to the complexity of the detection operation, only random inspection is possible. Due to the inaccuracy, incompleteness and lack of repeatability of the traditional manual inspection, it is difficult to use it as a basis for whether the product is qualified, which leads to the enterprise being quite passive in terms of product quality.

Scholars at home and abroad have been quite mature in the research on the detection of shape and position errors of mechanical parts, and many companies have already developed related instruments for the detection of shape and position errors, such as roundness meters and three-coordinate measuring instruments. However, the shape error detection of the sucker rod has its own particularity, and the roundness meter and the three-coordinate measuring instrument cannot be directly applied to the automatic detection of the sucker rod. The reasons are as follows: First, the roundness meter and the three-coordinate measuring instrument can only detect small rotary parts, especially the height of the rotary parts should not be too high, and at the same time, the parts to be tested are required to be fixed on the rotary table In addition, there are strict requirements on the placement of parts. The length of ordinary sucker rods is often more than 10 meters, and it is impossible to fix them on the workbench of these instruments; The shape and position error detection has very high requirements on the detection environment. The vibration in the sucker rod production environment is relatively large, and it is difficult to complete the measurement; thirdly, the roundness meter and the three-coordinate measuring It is specific. Although the reliability of their detection results is very high, because of the need to repeatedly adjust the position of the measured object before detection, the detection speed is very slow, and only sampling detection is still possible. Therefore, the existing detection equipment cannot meet the requirements of the enterprise for automatic detection of the shape and position error of the sucker rod, and it is necessary to develop an instrument and equipment dedicated to the detection of the sucker rod.
