Description

An ultrasonic non-destructive testing instrument for pipelines

technical field

The invention belongs to the technical field of industrial pipeline detection, and in particular relates to an ultrasonic nondestructive detector for pipelines.

Background technique

Ultrasonic testing is mainly to study the reflected, transmitted and scattered waves through the interaction between ultrasonic waves and the test piece, to detect and characterize the macroscopic defect detection, geometric characteristic measurement, organizational structure and mechanical properties of the test piece, and then to its Techniques for evaluation of specific applicability.

Non-destructive testing is to use the characteristics of sound, light, magnetism and electricity to detect whether there is a defect or inhomogeneity in the object under inspection without damaging or affecting the performance of the object under inspection, and to give the size and position of the defect The general term for all technical means to determine the technical state of the inspected object (such as whether it is qualified or not, and its service life, etc.)

Non-destructive testing is an indispensable and effective tool for industrial development. To a certain extent, it reflects the level of industrial development of a country, and its importance has been recognized. In November 1978, my country established a national non-destructive testing academic organization - the non-destructive testing branch of the Chinese Mechanical Engineering Society. In addition, metallurgy, electric power, petrochemical, shipbuilding, aerospace, nuclear energy and other industries have established their own non-destructive testing associations or associations; some provinces, autonomous regions, municipalities directly under the central government and prefecture-level cities have established provincial (city) and prefecture-level non-destructive testing Institutes or associations; Northeast, East China, Southwest and other regions have also established regional non-destructive testing societies or associations. The colleges and universities offering non-destructive testing professional courses in my country include Dalian University of Technology, Xi'an Polytechnic University, Nanchang Aviation Industry College and other institutions. There is still a big gap between our country and the world's advanced countries in the basic theoretical research of non-destructive testing and the development of instruments and equipment, especially in the aspects of high-tech testing equipment such as infrared and acoustic emission.

Industrial water is a major water-consuming industry in the use of water resources. In order to save energy, reduce emissions, and save water resources, the country generally takes the following specific measures: ①Repeat and recycle industrial water; ②Shut down some enterprises with serious pollution and serious waste of water;③ Encourage enterprises to build sewage treatment equipment; ④ strengthen the maintenance of enterprise water pipelines to prevent dripping and leakage. However, the general maintenance is to use the pipeline robot to overhaul the pipeline. The exposed water pipes are often ignored by people. The use of the pipeline robot will increase the economic cost. At present, there is an urgent need for a convenient and fast instrument that can detect the water pipes in time.
