Abstract
Способ определения негерметичности агрегатов, имеющих подвижные элементы, работающие в условиях вибровоздействия, заключающийся в определении негерметичности агрегата по изменению перепада давления с помощью датчика, отличающийся тем, что датчик перепада давления соединяют с системой дренажа агрегата, при этом момент начала работы датчика перепада давления и момент начала работы программы вибростенда по вибровоздействию на агрегат синхронизируют по времени, выбирают показания перепада давления от начала повышения давления и его конца и судят о негерметичности агрегата по величине расхода газа, используя известные зависимости и соответствующий диапазон частоты виброперегрузок.A method for determining the leakage of units having movable elements operating under vibration, which consists in determining the leakage of the unit by changing the differential pressure using a sensor, characterized in that the differential pressure sensor is connected to the drainage system of the unit, while the differential pressure sensor starts and the moment the beginning of the work of the vibration test program for vibration exposure on the unit is synchronized in time, the pressure differential readings are selected from the beginning of the pressure increase and its Nets and judge the leakage of the unit by the amount of gas flow using known dependencies and the corresponding frequency range of vibration overloads.
