Description
Изобретение относитс к контролю целостности конструктивных элементов изделий и может быть использовано дл обнаружени разрушени и контрол динамики нарушени целостности элементов изделий при их работе.The invention relates to the control of the integrity of the structural elements of products and can be used to detect the destruction and control the dynamics of the violation of the integrity of the elements of the products during their operation.
Наиболее близким к предлагаемому вл етс способ контрол целостности (герметичности) элементов изделий, согласно которому элементы изделий заполн ют рабочей средой (жидкость, газ), опрессовывают их и суд т о целостности элементов путем определени изменени состо ни параметров рабочей среды в них Cl.Closest to the present invention is a method for monitoring the integrity (tightness) of elements of products, according to which the elements of products are filled with a working medium (liquid, gas), they are pressured and the integrity of elements is judged by determining the change in the state of the parameters of the working medium in them Cl.
Однако определение изменени состо ни параметров рабочей среды в издели х возможно только при сквозных дефектах , т.е. фиксаци нарушени целостности элементов изделий осуществл етс в заключительной стадии dKBOSHOM дефекте. Кроме того, способ не дает возможности судить о целостности элементов изделий, выполненных из немагнитных материалов, по измене нию параметров рабочей среды.However, the determination of the change in the state of the parameters of the working medium in products is possible only with through defects, i.e. the fixing of the integrity of the elements of the products is carried out in the final stage of the dKBOSHOM defect. In addition, the method makes it impossible to judge the integrity of the elements of products made of nonmagnetic materials by changing the parameters of the working environment.
Цель изобретени - обнаружение начала разрушени и контроль динамики нарушени целостности немагнитных элемедтов .The purpose of the invention is to detect the onset of destruction and control the dynamics of the violation of the integrity of non-magnetic elements.
Указанна цель достигаетс тем, что согласно способу контрол целостности элементов изделий с рабочей средой элементы изделий заполн ют рабочей средой, опрессовывают их и суд т о целостности элементов путем определени изменени состо ни параметров рабочей среды в них, нанос т на контролируемые поверхности элементов This goal is achieved in that according to the method of controlling the integrity of elements of products with a working medium, the elements of products are filled with a working medium, they are pressed together and the integrity of elements is determined by determining the change in the state of the parameters of the working medium in them, applied to
10 ферромагнетики с температурой Кюри не меньшей значени рабочей температуры контролируемых -поверхностей элементов , намагничивают ферромагнетики, затем пропускают рабочую среду через 10 ferromagnets with the Curie temperature not lower than the operating temperature of the monitored -surfaces of the elements, ferromagnets are magnetized, then the working medium is passed through
15 элементы изделий и непрерывно контролируют наличие сигнала ЭДС индукции, по которому суд т о начале нарушени целостности элементов изделий, а по величине его - о динамике нарушени 15 elements of products and continuously monitor the presence of the signal of the EMF induction, which is judged on the beginning of the violation of the integrity of the elements of products, and the magnitude of it - on the dynamics of violation
20 целостности элементов изделий.20 integrity of elements of products.
На чертеже представлена схема per ализации способа контрол целостноети элементов изделий.The drawing shows a scheme for per- forming a method for controlling the integrity of product elements.
Способ осуществл ют следующим об25 разом.The method is carried out as follows.
На контролируемую поверхность 2 элемента 1 издели нанос т ферромагнетики Зт-З, которые выбирают по температуре Кюри, не меньшей температу30 . ры элементов изделий при их работе.On a controlled surface 2 of the element 1 of the product, ferromagnets of 3R-3 are applied, which are chosen according to the Curie temperature, not less than the temperature30. ry items in their work.
