Description

Воздушно-гелиева  смесь подаетс  из резервуара I во внутреннюю полость издели  3, испытываемого на герметичность. После нроведени  испытани  отработанна  смесь откачиваетс  компрессором 7 и собираетс  в ресивере 8.An air-helium mixture is supplied from reservoir I to the internal cavity of article 3, tested for tightness. After testing, the spent mixture is pumped out by compressor 7 and collected in receiver 8.

В результате откачки воздушно-гелиевой смеси из издели  давление в последнем падает, и по достижению заданной величины срабатывает датчик 11авлени  10, обеспечивающий подачу сигнала на включение дополнительного источника 4 сжатого воздуха. Расход воздуха выбираетс  таким, чтобы давлеьше в изделии не превышало давлени  испытаний , а врем  продувки задаетс  реле времени 11, св занным с отсечными клапанами 5 и 9. Воздух, поступивший в изделие, совместно с оставшейс  смесью, прогон етс  через блоки 6 с избирательной пронидаемостью по гелию, обеспечивающие повышение концентрации гели  в повторно используемой смеси и, следовательно, номинальный режим работы блока 17 выделени  низкокип щих компонентов , а увеличение давлени  в изделии, за счет притока воздуха от дополнительного источника сжатого воздуха, повьппает производительность компрессора 7, ссУ2 1ащал тем самым дикл испытани  издели .As a result of pumping an air-helium mixture from the product, the pressure in the latter drops, and when the specified value is reached, the sensor 11 of the sensor 10 is triggered, providing a signal to turn on the additional source 4 of compressed air. The air flow rate is chosen so that the pressure in the product does not exceed the test pressure, and the purge time is set by time relay 11 connected to the shut-off valves 5 and 9. The air entering the product, together with the remaining mixture, is passed through blocks 6 with selective permeability helium, providing an increase in the concentration of helium in the recycled mixture and, consequently, the nominal operating mode of the block 17 for the release of low-boiling components, and an increase in pressure in the product, due to the air flow from the additional source chnika compressed air, the compressor capacity povppaet 7 ssU2 1aschal thereby Diklo test article.

По истечении заданного времени дополнительный источник 4 сжатого воздуха отключаетс , отсчетные клапаны 5 и 9 закрываютс , избыточное давление воздуха из издели  сбрасываетс  и оно снимаетс  с позиции контрол .After a predetermined time has elapsed, the additional source 4 of compressed air is turned off, the readout valves 5 and 9 are closed, the excess air pressure from the product is released and it is removed from the control position.

Отработанна  смесь из ресивера 8 нагнетаетс  компрессором 12 в газгольдер 14. Из газгольдера смесь отсасываетс  компрессором 13 и направл етс  через блок 15 маслоочистки и блок 16 осушки и очистки от паров воды и углекислоты в блок 17The spent mixture from the receiver 8 is injected by the compressor 12 into the gas-holder 14. From the gas-holder, the mixture is sucked by the compressor 13 and is directed through the oil cleaning unit 15 and the drying unit 16 and cleaning from water and carbon dioxide in block 17

выделени  низкокип щих компонентов, где смесь вначале охлаждаетс  в теплообменнике 19, затем направл етс  в противоточный конденсатор 20, где происходит сжижение компонентов воздуха и образование газообразного гелиевого концентрата. Затем мембранным компрессором 21 гелиевый концентрат нагнетаетс  через теплообменник 22 в конденсатор 23 азота высокого давлени , в котором происходит отделение сжиженного азота от гели .extracting low-boiling components, where the mixture is first cooled in heat exchanger 19, then sent to countercurrent condenser 20, where the components of the air are liquefied and gaseous helium concentrate is formed. Then the membrane compressor 21 helium concentrate is injected through a heat exchanger 22 into a high pressure nitrogen condenser 23, in which the liquid nitrogen is separated from the helium.

Полученный 96-98%-ный газообразный гелий собираетс  в аккумул торе 18 дл  повторного использовани .The resulting 96-98% helium gas is collected in battery 18 for reuse.
