Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument, which can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. It can be used in both laboratory and engineering site. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical, offshore oil, pipelines, military industry, shipbuilding, automobiles, machinery manufacturing, metallurgy, metal processing, steel structures, railway transportation, nuclear power, universities, etc. industry.
Conventional methods of non-destructive testing include direct macroscopic inspection with naked eyes and instrumental testing such as radiographic flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, and eddy current flaw detection.
The sound wave frequency of ultrasonic flaw detection is 0.4-25 megahertz, and the most used one is 1-5 megahertz, which exceeds the hearing of human ears. Using sound to detect whether an object is good or bad has long been used by people. For example: pat the watermelon with your hands to see if it is ripe; the doctor knocks on the patient’s chest to check whether the internal organs are normal; knocks the porcelain bowl with your hand to see if it is broken, etc. Ultrasonic flaw detection has the characteristics of large detection distance, small size and light weight of the flaw detection device, which is easy to carry to the site for flaw detection, fast detection speed, and only consumes couplant and wear probes in flaw detection, and the total detection cost is low. At present, the construction industry market This method is mainly used for detection.
The lithium battery of ultrasonic flaw detector is a 14.8V lithium battery pack made of a single 18650 battery cell combined with 4 strings and 2 parallels and then packaged with green plastic. After long-term experimental application, this aluminum shell lithium battery represents the portable lithium battery advanced level.
Ultrasonic flaw detector detection can not only be very accurate, but also more convenient and faster than other detection methods, and will not cause harm to the detection object and operator, so it has been more and more popular among people.
So how do we choose the ultrasonic flaw detector battery?
Therefore, I recommend TEFOO ENERGY standard lithium battery, which is convenient for operators to carry out mobile indoor and outdoor operations. Providing continuous, efficient and stable mobile power supply has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries, so that the entire battery has the characteristics of high energy ratio, light weight, small size, high cycle life, high safety, and high consistency. The battery is very convenient to use, and the original battery can be directly replaced on site.
