K-XRAY Rotomat KT: tolshchina plenki pod kontrolem K-XRAY Rotomat KT — pervyy tolshchinomer dlya liniy po proizvodstvu rukavnykh plenok, osnovannyy na ispol’zovanii rentgenovskogo izlucheniya. Vpervyye on byl predstavlen na vystavke K 2019 v Dyussel’dorfe (Germaniya). K-XRAY, kak i drugiye datchiki, razrabotannyye firmy Hch. Kuendig, vstroyen v tolshchinomer Rotomat KT, kotoryy obespechivayet bystroye izmereniye profilya, chto yavlyayetsya vazhnym kriteriyem, osobenno pri proizvodstve bar’yernykh plenok. Ispol’zovaniye datchika K-XRAY pozvolyayet znachitel’no snizhat’ uroven’ ekspluatatsionnykh zatrat po sravneniyu s beta- i gamma-izluchatelyami i boleye tochno izmeryat’ tolshchinu bar’yernykh plenok. Izmeritel’nyye pribory s tverdotel’nymi izluchatelyami otlichayutsya dlitel’noy protseduroy polucheniya razreshayushchey dokumentatsii, dorogostoyashchey transportirovkoy i trudoyemkoy podgotovitel’noy rabotoy na meste montazha. Datchik K-XRAY ustranyayet eti problemy i sposoben izmeryat’ tonkiye plenki s uvelichennym razresheniyem. Poetomu tolshchinomer K-XRAY Rotomat KT yavlyayetsya ochevidnym vyborom dlya protsessa kontrolya bar’yernykh plenok. Vazhneyshimi preimushchestva tolshchi- nomera K-XRAY po sravneniyu s izmeritel’nymi priborami s tverdotel’nymi izluchatelyami yavlyayutsya sleduyushchiye: — net ogranicheniy v otnoshenii transportirovki; — ne trebuyetsya razresheniye na vvoz; — poluchit’ razresheniye na ekspluatatsiyu namnogo proshche (zachastuyu dostatochno onlayn-registratsii); — obespechivayet boleye vysokoye razresheniye; — uvelichena tochnost’ izmereniya tolshchiny (osobenno tonkikh plenok); — potrebleniye szhatogo vozdukha umen’sheno na 70%; — yest’ termoreguliruyemaya vozdushnaya podushka; — otsutstvuyut zatraty na utilizatsiyu. Radiatsionnaya bezopasnost’ Ispol’zovaniye tolshchinomera K-XRAY Rotomat KT znachitel’no snizhayet trebovaniya k radiatsionnoy bezopasnosti, poskol’ku riski radioaktivnogo oblucheniya rezko umen’shayutsya. Vo mnogikh stranakh sushchestvuyut opredelennyye pravila i predpisaniya po ekspluatatsii rentgenovskikh izluchateley. Zakazchiki dolzhny utochnit’ eti trebovaniya dlya svoyego regiona. Ekraniruyushchiye i predokhranitel’nyye ustroystva Pikovoye napryazheniye rentgenovskikh trubok sostavlyayet 19 keV. Eto napryazheniye voznikayet pri maksimal’noy energii rentgenovskogo lucha. Sredniy pokazatel’ energii sostavlyayet meneye 15 keV, chto sovsem nemnogo po sravneniyu s meditsinskimi rentgenovskimi apparatami, kogda napryazheniye pri skanirovanii organov grudnoy kletki vzroslogo cheloveka sostavlyayet pochti 100 keV, pri snimke ruk — 40 keV, a pri snimke grudnoy kletki — 30 keV. Poskol’ku energiya izlucheniya K-XRAY nevelika, a luch dostatochno uzkiy, zashchitnyye ekrany nedorogi v izgotovlenii i prosty v ustanovke. Oni izgotavlivayutsya iz standartnogo stal’nogo lista tolshchinoy okolo 1 mm i imeyut vysotu ne boleye 1 m v zavisimosti ot maksimal’nogo rasstoyaniya istochnika izlucheniya ot ekrana. V ekrane imeyetsya lyuk, obespechivayushchiy prostoy dostup k oborudovaniyu dlya vypolneniya rabot po tekhnicheskomu obsluzhivaniyu. Dvertsa lyuka svyazana s istochnikom pitaniya rentgenovskoy sistemy, kotoraya pri yeye otkrytii avtomaticheski otklyuchayetsya. Dublirovannyye zashchitnyye signal’nyye lampy (krasnaya i zelenaya), ustanovlennyye za predelami ekranirovannoy zony, nepreryvno informiruyut o sostoyanii sistemy (vkl/vykl). Za predelami ekrana doza oblucheniya nastol’ko mala, chto ni zashchita ot oblucheniya, ni kontrol’ ne trebuyutsya. Ещё 3268 / 5000 Результаты перевода K-XRAY Rotomat KT: film thickness under control

The K-XRAY Rotomat KT is the first X-ray based film thickness gauge for tubular production lines. It was first presented at the K 2019 exhibition in Dusseldorf (Germany). K-XRAY, like other sensors developed by Hch. Kuendig, integrated in the Rotomat KT thickness gauge, provides rapid profile measurement, which is an important criterion, especially in the […]
