Description
(54) СПОСОБ ИСПЫТАНИЯ ИЗДЕЛИЙ . ПРИ ПОВЫШЕННЫХ ТЕМПЕРАТУРАХ(54) METHOD OF TESTING PRODUCTS. AT INCREASED TEMPERATURES
Известен способ испытани изделий при повышенных температурах, заключающийс в том, что испытуемое изделие помещают в вакуум-камеру,- с двойными стенками, образук цими замкнутую полость, откачиваютThe known method of testing products at elevated temperatures is that the test product is placed in a vacuum chamber, with double walls, forming a closed cavity, pumped out
.вакуум-камеру, нагревают изделие и охлаждают стенки подачей охлаждающей среды в .полость между стенками..vacuum chamber, heat the product and cool the walls by supplying a cooling medium to the cavity between the walls.
При испытании изделий в режиме нагрева известным способом необходима дополнительна теплоизол ци , что не только усложн ет испытательное оборудование, но и не позвол ет в некоторых сллча х выдержать заданный режим нагрева и охлаждени .When testing products in heating mode in a known manner, additional thermal insulation is necessary, which not only complicates the test equipment, but also does not allow in certain cases to withstand the specified heating and cooling mode.
Предлагаемый способ отличаетс от известного тем, что в нем при испытании иэ делий в режиме нагрева теплоизол цию каме ы осуществл ют вакуумированием полости между стенками вакуум-камеры, что позвод ет упростить исиытатепьное оборудование и к тому же более точно выдерживать температурный режим при теплосменах.The proposed method differs from the well-known fact that, when tested during the heating mode, the heat insulation of the chamber is performed by evacuating the cavity between the walls of the vacuum chamber, which simplifies the experimental equipment and, moreover, withstands the temperature during the thermal changes.
На чертеже изображена схема устройства дл реализации предложенного способа. The drawing shows a diagram of the device for implementing the proposed method.
Устройство содержит вакуум-камеру 1 с двойными Стенками 2 н 3, образующими замкнутую полость 4. Испытуемое изделие 5 устанавливают на испытательный стол 6, снабженный нагревателем 7. Дл откачки i камеры 1 н полости 4 устройство содержит вакуумирующую систему 8. Подача охлаждающей среды в полость 4 осуществл етс либо системой 9 вод ного охлаждени , либо системой 1О газового охлаждени . Устройство оборудовано ..контрольно-измерительной, аппаратурой 11.The device contains a vacuum chamber 1 with double walls 2 n 3 forming a closed cavity 4. Test product 5 is installed on a test table 6 equipped with a heater 7. To pump i chamber 1 n cavity 4, the device contains a vacuum system 8. Coolant supply to the cavity 4 is carried out either by the water cooling system 9 or by the gas cooling system 1O. The device is equipped with measuring and instrumentation 11.
Испытуемое изделие 5 помещают в ва куум-камеру 1, откачиваютвакуум-камеру |с помощью вак мирующей системы 8 и нагревают с помощью нагревател 7. Стен ки вакуум-камеры 1 охлаждают с помощью системы 9 вод ного охлаждени или системы 10 газового охлаждени .The test article 5 is placed in the vacuum chamber 1, the vacuum chamber is pumped out using the vacuum system 8 and heated using the heater 7. The walls of the vacuum chamber 1 are cooled using the water cooling system 9 or the gas cooling system 10.
При испытании издели : 5 в режиме нйгрева систему 9 вод ного охлаждени и систему 1О газового охлаждени отключают и дл теплоизол ции вакуум-камеры 1 ва- куумируют полость 4 между стенками 2 и .3. Такой прием позвол ет использоватьWhen testing the product: 5 in the heating mode, the water cooling system 9 and the gas cooling system 1O are disconnected and the cavity 4 between the walls 2 and .3 is evacuated for heat insulation of the vacuum chamber 1. This technique allows you to use
