Description

контролируемой поверхнОСти издели ) до заданной величины разрежени  над ловерхностью жидкости 2. После этого отсечной вентиль 6 закрывают, и величину течи определ ют путем сравнени  частоты отрыва пузырьков .газа с капилл ра трубки 4 и е капилл ра эталонной течи 7, благодар  чему величина течи определ етс  без интегрирован«  iBO времени и ее измеренна  величина не зависит от .колебаний давлени  (разрежени ) в сосуде.the controlled surface of the product) to a predetermined vacuum value over the fluid surface 2. Thereafter, the shut-off valve 6 is closed, and the leakage value is determined by comparing the bubble detachment frequency of gas from the capillary tube 4 and the standard leakage capillary 7, thereby determining the leakage The iBO time is integrated without integration and its measured value does not depend on the pressure (vacuum) fluctuations in the vessel.
