Abstract

"BANCO DE ENSAIO PARA A DETERMINAçãO DE PRESSõES EM UNIDADES ESTRUTURAIS SOLICITADAS COM PRESSãO". A invenção refere-se a um dispositivo para determinação de níveis de pressão diferentes em unidades estruturais (12, 13) que, para fins de ensaio que são ligadas por uma tubulação de ensaio (3, 14). Na tubulação de ensaio (3, 14) são integrados um modem (15) assim como uma unidade de entrada/saída (17) com eletrónica de interpretação (16) ligada na entrada.Entre uma fonte de pressão (1) e a unidade estrutural a ser ensaiada (12, 13) são acolhidas uma primeira válvula de comando (2) e uma segunda válvula de comando (5). Com estas a unidade estrutural (12, 13) a ser ensaiada pode ser solicitada com uma primeira pressão, pode ser produzida uma segunda pressão em um recipiente de acumulação (10) e a unidade estrutural (12, 13) ser solicitada com a segunda pressão."TEST BENCH FOR DETERMINING PRESSURES IN PRESSURE REQUESTED STRUCTURAL UNITS". The invention relates to a device for determining different pressure levels in structural units (12, 13) which for test purposes are connected by a test pipe (3, 14). In the test tube (3, 14) a modem (15) as well as an input / output unit (17) with interpretation electronics (16) connected to the input are integrated. Between a pressure source (1) and the structural unit To be tested (12, 13) a first control valve (2) and a second control valve (5) are received. With these the structural unit (12, 13) to be tested can be ordered with a first pressure, a second pressure can be produced in an accumulation vessel (10) and the structural unit (12, 13) can be ordered with the second pressure. .
