Today thermal power stations by the SIEMENS AG are more than ever complex high-tech products. They provide a continuous and reliable electrical power supply for industry and population worldwide. They do this using fossil fuels very efficient and therefore exceptionally friendly for our environment. To achieve this highest quality of every single component is absolutely imperative. Thus heavily stressed parts like the turbine blades are tested with the latest measurement techniques for example with infrared thermography.
During the production of the turbine blades for thermal power stations the Siemens AG uses ceramic coatings since higher entry temperatures to the turbine blades are reachable which increases efficiency. Thereby it is necessary to ensure the correct application of the coatings without any losses at the flow channels. Mr. Sczepurek together with his team takes the responsibility for the
required test techniques and processes. Out of the range of non-destructive testing methods he chose infrared thermography as it allows for checking large turbine areas particularly fast and reliable at the same time.
InfraTec supports this quality assurance by supplying highperformance and reliable infrared cameras from its own ImageIR® series manufactured in Dresden. The geometric resolution of 640 x 512 pixels being high for commercial, cooled thermal cameras provides together with a fast frame rate the necessary prerequisites to realize the test of every turbine reliably but also in economically justifiable time.
A fast motorized focussing as well as a data acquisition to the split milisecond and a camera control by a capable and customizable software of InfraTec also plays an important role. The flexible interface concept of the ImageIR® camera moreover allows for a seamless integration into the existing system environment. Additionally, the infrared cameras of the ImageIR® series can be combined with external excitation devices due to its precise trigger possibility. Thus, further parameters of turbine blades can be determined within the methodology of active heat flow thermography. Their analysis and
practical application result in a further increase in efficiency for the customers of the thermal power stations of the SIEMENS AG.

?在我們的日常生活中,紅外熱像儀是非常常見的,很多用途都用的到它。紅外熱像儀是一種用來探測目標物體的紅外輻射,并通過光電轉(zhuǎn)換、電信號處理等手段,將目標物體的溫度分布圖像轉(zhuǎn)換成視頻圖像的高科技產(chǎn)品。
?紅外熱成像測量技術,它的理論基礎是一切物體當溫度達到絕對零度(0.0K或-273.15℃)以上時都會發(fā)射電磁輻射這一物理現(xiàn)象。紅外熱成像系統(tǒng)中集成的探測器可以捕捉物體表面產(chǎn)生的紅外光譜范圍內(nèi)的輻射能并將其轉(zhuǎn)變成電信號。
?紅外熱成像儀是什么?紅外熱成像儀是運用光電技術檢測物體熱輻射的紅外線特定波段信號,將該信號轉(zhuǎn)換成可供人類視覺分辨的圖像和圖形,并可以進一步算出溫度值。淺顯點來說,紅外熱成像儀是打破人類視覺障礙,將那些由于屏蔽而無法看到的部分轉(zhuǎn)換為可視化的圖像,可以幫忙許多范疇進行勘探、檢測、區(qū)分等的運用。
?紅外熱像儀在各種設備中有突出的應用,在早前它的功能相對單一,僅僅提供熱成像服務,后期還需要經(jīng)過人工的監(jiān)控或手動的合成等來達到相應的目的,但是現(xiàn)在的紅外熱像儀可以直接生成圖像,并且用于體溫的檢測,那么為什么選擇非制冷紅外熱像儀??
?高性能的消防熱成像儀具備很多不同的功能且所適用于的領域也非常廣泛,特別是在消防領域當中其能夠更好的為火災救援提供很多的輔助作用,故而這種精密的光學設備在消防當中的使用也逐漸增多。那么消防熱成像儀在消防當中的作用是什么?下面就這個問題做詳細闡述。
