Abstract
1. Способ нагружения полых изделий при испытаниях их на прочность и герметичность, заключающийся в заполнении их жидкостью с сохранением воздушного пространства, герметизации полости и нагрева изделия, отличающийся тем, что, с целью повышения точности нагружения многополостных изделий, объем Vвоздушного пространства каждой полости определяют из соотношениягде P- испытательное давление для данной полости;V- объем данной полости изделия;β- коэффициент объемного расширения жидкости, заполняющей данную полость;t- температура нагрева;t- температура окружающей среды;P- давление окружающей среды.2. Способ по п.1, отличающийся тем, что для заполнения каждой полости используют жидкость, для работы с которой предназначена данная полость.1. The method of loading hollow products when testing them for strength and tightness, consisting in filling them with liquid while maintaining air space, sealing the cavity and heating the product, characterized in that, in order to improve the loading accuracy of multi-cavity products, the volume of air in each cavity is determined ratios where P is the test pressure for a given cavity; V is the volume of a given cavity of a product; β is the coefficient of volumetric expansion of the fluid filling this cavity; t is the heating temperature; t is the rate the environment of the environment; P- pressure of the environment.2. A method according to claim 1, characterized in that a fluid is used to fill each cavity, for which the cavity is intended to work.
