the radial sealing of the rotating u043fu0440u043eu0442u0438u0432u043eu0432u044bu0431u0440u043eu0441u043eu0432u043eu0433u043e u043fu0440u0435u0432u0435u043du0442u043eu0440u0430

摘要

as an example of implementation options are to increase the durability of the rotating device and the u043fu0440u043eu0442u0438u0432u043eu0432u044bu0431u0440u043eu0441u043eu0432u043eu0433u043e u043fu0440u0435u0432u0435u043du0442u043eu0440u0430 stem sc vazhiny, includes a bearing hub, to work in the u043fu0440u043eu0442u0438u0432u043eu0432u044bu0431u0440u043eu0441u043eu0432u043eu043c u043fu0440u0435u0432u0435u043du0442u043eu0440u0435.bearing hub is made for reduced pressure near the u043fu043eu0434u0448u0438u043fu043du0438u043au043eu0432u043eu0433u043e node, which includes reducing the pressure in the u0440u0430u0434u0438u0430u043bu044cu043du043eu043c seal. the top and bottom sealing installed fixedly to a durable casing, associated with the internal element located in the u043fu043eu0434u0448u0438u043fu043du0438u043au043eu0432u043eu043c node.the shell is accomplished with an endurance sealing upper and lower compaction compaction when the inner element rotates in the counter u0432u044bu0431u0440u043eu0441u043eu0432u043eu043c u043fu0440u0435u0432u0435u043du0442u043eu0440u0435.system for reducing pressure, fitted with rotating u043fu0440u043eu0442u0438u0432u043eu0432u044bu0431u0440u043eu0441u043eu0432u044bu043c u043fu0440u0435u0432u0435u043du0442u043eu0440u043eu043c, accomplished with the possibility of application of pressure by the pressure in the barrel. e wells between the upper and the lower compaction compaction that is lower than the pressure above the upper compaction and higher pressure under the lower thickened.
