Abstract

"PROCESSO DE DETECçãO DE VAZAMENTOS DE AR EM PNEUS E EM MáQUINAS DE TESTE DE PNEUS". A presente invenção se refere a um processo e a um sistema para detectar vazamentos de ar em pneus e em uma máquina de teste de pneus. Cada um dos pneus é montado na máquina de uniformização de pneus, inflado com um fluxo de ar de um sistema de inflação a uma primeira pressão, e mantido na primeira pressão por suprimento contínuo de ar do sistema de inflação para o pneu. O fluxo do suprimento contínuo de ar é medido com um sensor de fluxo calorimétrico, calibrado para transmitir um sinal do sensor tendo um valor de escala integral correspondente a um pneu de modelo idêntico montado na máquina de uniformização de pneus, sem quaisquer vazamentos de ar no pneu modelo ou na máquina de teste. O fluxo do suprimento contínuo de ar é comparado com um fluxo médio para os pneus medidos previamente montados na máquina de uniformização de pneus, sem quaisquer vazamentos de ar nos pneus ou na máquina de teste. Um sinal de controle indicando um vazamento de ar é transmitido, se o sinal do sensor é de 20 a 80% do valor da escala integral.
