نقد و بررسی

مولد اشعه ایکس MITECH یک تشخیص عیب اشعه ایکس قابل حمل برای آزمایش غیرمخرب اشعه ایکس است، از تفاوت درجه جذب به ضخامت مواد برای تشخیص عیوب داخلی مواد استفاده می کند. این آشکارساز دارای مزایای اندازه کوچک، وزن سبک، حمل آسان، عملکرد ساده است، به ویژه برای کار مشترک با واحدهای تولید برق در محیط های مختلف سخت مناسب است. مواد فیلم می توانند به طور مستقیم اندازه و شکل عیوب داخلی قطعه کار را نشان دهند، تصویر نقص منعکس شده بر روی فیلم واقعی و واضح است و می توان آن را برای مدت طولانی حفظ کرد. بدون الزامات خاص به زبری سطح قطعه کار. اثر اندازه دانه ماده تأثیر کمی بر نتایج آزمایش دارد که برای تشخیص عیب داخلی مواد مختلف اعمال می شود. با توانایی ضد تداخل قوی، پایداری خوب، عملکرد قابل اعتماد، دارای مزایای آشکار در ساخت و ساز و عملیات ارتفاع بالا است، به طور گسترده ای در کشتی سازی، ساخت ماشین آلات، حمل و نقل هوایی، راه آهن، مخازن تحت فشار، دیگهای بخار، نفت، صنایع شیمیایی، صنایع دفاعی ملی و سایر صنایع استفاده می شود. تجهیزات ایده آل برای آزمایش های غیر مخرب است.

Function & application
The instrument can be widely used in shipbuilding, machinery manufacturing, aviation, railway, pressure vessels, boilers, oil, Chemical industry, national defense industry and other industries, is the ideal equipment for nondestructive testing.

Working Principle
X ray generator produce X-ray film, using the different absorption degree between the material and thickness to display the internal defects of parts and weld seam in the film, according to the nature, size and location of the defect to evaluate the quality of materials and products.

This series of X-ray generator adopts silicon controlled single-phase bridge rectifier, rectified voltage changed into DC voltage through LC filter circuit. This voltage converted into a unidirectional pulse with a variable frequency by thyristor chopper circuit, the sent into high-voltage pulse transformer for power supply to the X ray generator. This voltage of tens KV even hundred KV is added in X ray tube (a two staged tube) at both ends, electrons from the cathode to anode direction to accelerate and get a great amount of energy. when the high-speed electrons strike the anode, and by interacting with the anode metal atoms outside the nuclear Coulomb field, emit X rays.

When X ray through the material, the intensity gradually weakened. The important properties of X rays is to expose the film, just like ordinary light, it can make the silver halide in film emulsion layer to produce latent image center, after developing and fixing will be blackened, the more it receiving the ray the more black the film is. This effect is called the photographic effect. Because the photographic effect of X ray on the silver halide is much smaller than that of ordinary light, so you must use the special X ray film, both sides of this film are coated with a thick latex; in addition, also need to use a photosensitive screen which can strengthen the effect, the screen is usually made of lead foil. Put the exposed film in the darkroom, after developing, fixing, washing and drying, then observing the dried film on the viewbox , according to the images of defective parts and non-defects. We can determine the type, number, size of defects, and this is the principle of radiographic inspection.
