Description

хорошую адгезионную способность к материалам деталей резьбового соединени , невысо; кую в зкость в расплавленном состо нии и должен быть коррозионно устойчивым.good adhesiveness to materials of parts of a threaded joint, low; viscosity in the molten state and must be corrosion resistant.

Процесс сборки осуществл етс  в следующем пор дке.The assembly process is carried out in the following order.

Готов т резьбовые участки под нанесение пленки стопор щего состава (обезжиривают, удал ют слой окислов и т. д.). Нанос т на резьбовые участки тонкую пленку стопор щего состава. Нагревают участки резьбового соединени  до температуры, несколько более высокой , чем температура плавлени  пленки стопор щего состава. Собирают и зат гивают резьбовое соединение в нагретом состо нии. Охлаждают резьбовое соединение.Threaded sections are prepared for application of a film of a retaining compound (degrease, remove the oxide layer, etc.). A thin film of the locking compound is applied to the threaded areas. The parts of the threaded joint are heated to a temperature somewhat higher than the melting point of the film of the retaining composition. Collect and tighten the threaded joint in a heated condition. Cool the threaded connection.

При этом нанесенна  термопластична  пленка в местах контактировани  боковых поверхностей витков при зат жке будет выдавлена в сторону верщин профил , образу  в момент начала отвердевани  между детал ми резьбового соединени  дополнительные св зи, которые впоследствии преп тствуют относительному провороту их при опасности самоотвинчивани . При зат жке резьбового соединени  термопластична  пленка играет роль смазки, резко снижа  коэффициент трени  в резьбе. В процессе эксплуатации резьбового соединени  она защищает от коррозии и герметизирует резьбовые участки.In this case, the applied thermoplastic film at the points of contact of the side surfaces of the coils during tightening will be extruded into the side of the profile, forming at the time of the beginning of hardening between the details of the threaded connection additional links, which subsequently prevent them from turning in relative danger of self-unscrewing. When tightening the threaded joint, the thermoplastic film plays the role of lubricant, drastically reducing the coefficient of friction in the thread. During operation of the threaded joint, it protects against corrosion and seals the threaded sections.

Демонтаж резьбового соединени  производитс  в обратном сборке пор дке, т. е. после нагрева соединени  до температуры плавлени  термопластичного сло  соединение легко может быть демонтировано.The disassembly of the threaded joint is performed in reverse order, i.e., after the joint is heated to the melting temperature of the thermoplastic layer, the joint can easily be removed.

Технико-экономическа  эффективность данного способа выражаетс  в повышении надежности резьбовых соединений, особенно в услови х вибрационных нагрузок, снижении трудоемкости сборки и разборки, многократного использовани  деталей соединени  без специальной подготовки.The technical and economic efficiency of this method is expressed in increasing the reliability of threaded connections, especially under vibration load conditions, reducing the laboriousness of assembly and disassembly, and repeated use of parts of the joint without special training.
