Между наружной стенкой металлической конструкции 2 и штуцером 9 размещено уплотнение 14. Between the outer wall of the metal structure 2 and the fitting 9 is placed a seal 14.
Работа устройства. The operation of the device.
Под воздействием циклических нагрузок в стенках металлических конструкций в результате усталости металла появляются микротрещины, через которые в закрытые полости проникает влажный воздух и конденсируется в виде капель воды. Скопление воды приводит к коррозии не защищенной поверхности стенок полости, вследствие чего происходит разрушение металлической конструкции. Under the influence of cyclic loads in the walls of metal structures as a result of metal fatigue microcracks appear through which moist air penetrates into closed cavities and condenses in the form of water droplets. The accumulation of water leads to corrosion of the unprotected surface of the walls of the cavity, resulting in the destruction of the metal structure.
Согласно предложенной технологии, полости в металлической конструкции заполняются вспененным рабочим материалом типа полиуретана. Для равномерного и полного заполнения закрытой полости рабочим материалом в стенках металлической конструкции выполняют два отверстия. Через одно из них в полость под давлением через форсунку подают рабочий материал, а второе отверстие служит для удаления воздуха с помощью вакуумного насоса. According to the proposed technology, the cavities in the metal structure are filled with foamed working material such as polyurethane. For uniform and complete filling of the closed cavity with working material, two holes are made in the walls of the metal structure. Through one of them, a working material is fed into the cavity under pressure through the nozzle, and the second hole serves to remove air using a vacuum pump.
Устройство, которое реализует предложенный способ, работает следующим образом. A device that implements the proposed method works as follows.
Распылительную форсунку 3 соединяют с отверстием 7 в корпусе металлической конструкции 2. Отверстие 8 через штуцер 9 соединяют с камерой низкого давления 10, а сопло эжектора 11 струйного насоса подключают к компрессору 12. Для повышения эффективности работы вакуумного насоса между
штуцером 9 и стенкой металлической конструкции 2 размещают уплотнение, которое герметизирует отверстие 2 и исключает всасывание наружного воздуха из атмосферы. The spray nozzle 3 is connected to the hole 7 in the body of the metal structure 2. The hole 8 through the nozzle 9 is connected to the low pressure chamber 10, and the nozzle of the ejector 11 of the jet pump is connected to the compressor 12. To increase the efficiency of the vacuum pump between the fitting 9 and the wall of the metal structure 2 place a seal that seals the hole 2 and prevents the absorption of outside air from the atmosphere.
Сжатый воздух из компрессора 12, проходя через сопло эжектора 11 создает разряжение воздуха в камере низкого давления 10 и соответственно в понижается давление воздуха в полости металлической конструкции 2. Compressed air from the compressor 12, passing through the nozzle of the ejector 11 creates a vacuum in the low-pressure chamber 10 and, accordingly, the air pressure in the cavity of the metal structure 2 decreases.
Подача рабочего материала 6 из емкости 5 в полость регулируется включением дозатора 4. В области пониженного давления рабочий материал 6 вспенивается, увеличивается в объеме и заполняет все полость. Понижение давления внутри полости позволяем ускорить процесс заполнения и увеличивает объем вспененного материала, что уменьшает его расход. The supply of the working material 6 from the tank 5 into the cavity is controlled by the inclusion of the dispenser 4. In the area of reduced pressure, the working material 6 foams, increases in volume and fills the entire cavity. Reducing the pressure inside the cavity allows us to accelerate the filling process and increases the volume of foam material, which reduces its consumption.
Подача рабочего материала 6 из емкости 5 продолжается до момента появления пены из отверстия 8, после чего дозатор 4 прекращает подачу рабочего материала 6 и штуцер 9 отсоединяют от отверстия 8. Отверстия 7 и 8 заглушаются саморезными шурупами 13 или другими заглушками. The supply of working material 6 from the container 5 continues until the appearance of foam from the hole 8, after which the dispenser 4 stops the flow of the working material 6 and the nozzle 9 is disconnected from the hole 8. The holes 7 and 8 are plugged with self-tapping screws 13 or other plugs.
Предложенная технология предназначена для антикоррозийной защиты полых металлических конструкций, расположенных в районах с влажным климатом и подверженых воздействию циклических нагрузок. Преимуществом данного изобретения является возможность защиты от воздействия влажного климата металлических конструкций, которые уже находятся в эксплуатации. The proposed technology is intended for anticorrosion protection of hollow metal structures located in areas with a humid climate and subject to cyclic loads. An advantage of this invention is the possibility of protection against the effects of a humid climate of metal structures that are already in operation.
