When it comes to selecting the right ultrasonic pipe testing equipment for your needs, there are a few factors that you should consider. From the brand to the features, there are several important asp...
The eddy current flaw detector is the most popular instrument in the equipment industry among non-destructive flaw detectors. The eddy current flaw detector has the advantages of high practicability and high-cost performance, which has been loved by the majority of consumers.
The international eddy current nondestructive testing market is developing rapidly, and many companies choose to use eddy current flaw detectors. The eddy current testing machine is composed of the signal oscillator, probe coil, detection and measurement control circuit, signal processing, alarm display and power supply. When there are defects or cracks on the surface of the pipe under test, the magnetic flux passing through the probe coil will change. According to the size and distribution of the eddy current, the parameters that affect the electrical characteristics of the coil can be detected, so that the pipe defect can be found.
Based on the eddy current testing principle, the eddy current flaw detector adopts modern AC motor speed control technology for speed control. In this way, the speed of the rollers on both sides of the main machine and the speed of the rotating pressure wheel can be variably adjusted to meet the needs of different detection speeds. The peripheral circuit is simple and the appearance is beautiful. Due to the AC motor, compared with the old DC motor speed control technology, it has the advantages of simple motor structure, no spark interference, reliable performance and convenient maintenance.
1. When transporting the instrument, handle it gently to prevent collisions to prevent damage to the internal components of the instrument.
2. When the instrument fails, please do not disassemble or repair it by yourself, and then repair it after contacting the factory's technicians.
3. Keep it properly and make it away from moisture and dust.
The eddy current flaw detector is a conventional non-destructive flaw detector for eddy current non-destructive testing. It is suitable for testing the quality of processing and welding of pipelines, aircraft, vehicles and bridges and other materials and parts of industrial parts such as petroleum, transportation and construction, as well as all kinds of light metals, steel pipes, and copper. The quality of processed parts such as tubes and aluminium tubes.
The eddy current flaw detector is an applied metal part, which has a discontinuity. This feature causes partial distortion of the magnetic lines of force on the surface and near the surface of the workpiece to cause adsorption. The magnetic powder applied on the surface of the workpiece constitutes a visually visible magnetic mark under suitable light, and then shows the position, shape and details of the discontinuity.
