Description

тнетают в него воздух. Под действием скоростного напора шары 4, а вместе с ними и шнур перемешаютс  по трубопроводу за завал к месту нахождени  пострадавшего. Наличие щетины ., пор док расположени  ее на шарах в шахматном пор дке создают оптимальные услови  дл  взаимодействи  воздушного потока с шарами и их перемещение по трубопроводу как на пр мых участках , так и на поворотах и суженных местах, например, фланцев 7, также , обеспечивает оптимальный расход воздуха и сокращает врем  перемещени  устройства по трубопроводу за завал. По величине давлени  воздуха в трубопроводе, по которому перел5ещаетс  устройство дл  св зи, суд т о перемещен ии устройства (давление дер:житс  примерно nocTOHHHb M)jO заторе устройства в . трубопроводе (давление резко повышаетс ), и контролируют врем  выхода устройства за завал (давление резко снижаетс  - падает). Последнее позвол ет выбрать врем  прекращени  нагнетани  излишнего количества воздуха с избыточным давлением за завал.pushing air into it. Under the action of the velocity head, the balls 4, and with them the cord are mixed through the pipeline behind the blockage to the location of the victim. The presence of bristles, the order of its location on the balls in a staggered order, create optimal conditions for the interaction of the air flow with the balls and their movement through the pipeline both in straight sections and in turns and narrowed places, for example, flanges 7, also provides optimal air flow and shortens the time it takes to move the device through the pipeline to block. The pressure of the air in the pipeline through which the communication device is transferred indicates the displacement of the device (pressure region: approximately nocTOHHHb M) jO of the device c. in the pipeline (the pressure rises sharply), and control the time the device leaves the block (the pressure decreases sharply - decreases). The latter allows you to choose the time for stopping the injection of excess air with excess pressure over the dam.
