Description
да. 5 до давлени на Ю-15 жж рт. ст. ниже давлени насыщенных паров рабочей жидкости, которое регистрируют вакуумметром 7.Yes. 5 to pressure on S-15 LJH. Art. below the saturated vapor pressure of the working fluid, which is recorded with a vacuum gauge 7.
Гидронасос iS создает посто нную циркул цию рабочей жидкости по замкнутому циклу. С помощью течеискател 9 измер ют начальную и конечную концентрации контрольного газа.The iS hydraulic pump creates a constant circulation of working fluid through a closed cycle. Using a leak detector 9, the initial and final concentrations of the control gas are measured.
Способ осуществл етс следующим образом .The method is carried out as follows.
С помощью гидронасоса 8 создают посто нную циркул цию рабочей жидкости по замкнутому циклу. Посредством течеискател i9 измер ют начальную концентрацию контрольного газа в объединенной гидросистеме.The hydraulic pump 8 is used to create a constant circulation of the working fluid in a closed cycle. Leak detector i9 measures the initial concentration of the control gas in the combined hydraulic system.
В замкнутый объем 2 подают контрольный газ до рабочего давлени . Через определенное врем контрольный газ благодар микронеплотности гидросистемы / проникает в рабочую жидкость и с помощью гидронасоса «S транспортируетс в емкость 4, где освобождаетс , вызыва изменение концентрации над свободной поверхностью емкости.Control volume up to the working pressure is supplied to the closed volume 2. After a certain time, the control gas due to the micro-tightness of the hydraulic system / penetrates into the working fluid and using the hydraulic pump "S" is transported to the tank 4, where it is released, causing a change in concentration above the free surface of the tank.
Таким образом, в результате установлени динамического равновеси между иоступл1ением контрольного газа в рабочую жидкость и дегазацией его в емкости устанавливаетс пропорциональна зависимость между негерметичностью контролируемой системы и концентрацией контрольного газа над свободным объемом емкости 4.Thus, as a result of establishing a dynamic equilibrium between the availability of the test gas to the working fluid and its degassing in the tank, a proportionality is established between the leakage of the system under control and the concentration of the test gas over the free volume of the tank 4.
С помощью течеискател 9 измер ют конечную концентрацию контрольного газаUsing the leak detector 9, the final concentration of the control gas is measured.
и по изменению концентрации контрольного газа суд т о герметичности.and based on the change in the concentration of the test gas, a tightness is judged.
При использовании предлагаемого способа сокращаетс продолжительность контрол гидросистем и по вл етс возможность контрол непосредственно в процессе эксплуатации.When using the proposed method, the duration of control of hydraulic systems is reduced and it becomes possible to control directly during operation.
