Description
(54) ТУРБОДЕТАНДЕР(54) TURBODETANDER
Изобретение относитс к холодильной технике, в частности к низкотемпературным турбодетандерам, и может быть использовано в газовой и химичес кой промышленност х. Известен турбодетандер, содержащий вал, турбинное и компрессорное колеса с входными и выходными полост ми, а также подшипниковые узлы с подвод щими и сливными полост ми l. Недостатком известной конструкции вл етс больша утечка смазочного материала подшипниковых узлов в газопробочную часть турбодетандера. Цель изобретени - повышение надежности работы турбодетандера. Поставленна цель достигаетс тем, что сливные полости подшипниковых узлов со стороны турбинного и КОМПрвСсорного колес .сообщены каждое соответ ственно с выходной камерой турбинного колеса и входной камерой компрессорно го .колеса посредством осевых каналов с радиальными отверсти ми, выполненными в валу. На чертеже представлен турбодетандер . Турбодетандер содержит вал 1, турбинное 2 и компрессорнбе 3 колеса с входными 4 и 5 и выходными 6 и 7 полост ми , подшипниковые узлы 8 и 9, подвод щие 10 и сливные 11 полости, осевые каналы 12 с оадиальными отверсти ми 13 и 14 и уплотнительные узлы 1 5 . При работе турбодетандера смазочный материал подаетс в подвод щие полости 10, герметизированные от газопроточной части уплотнительными узлами 15, проходит через подшипниковые узлы 8 и 9 и поступает в сливные полости 11. Дл уменьшени утечек смазки в газопроточную часть на валу 1 выполнены осевые каналы 12 с радиальным отверсти ми 13 и 14, выполн ющие в совокупности роль сепаратора смазки.The invention relates to refrigeration engineering, in particular, to low temperature turboexpanders, and can be used in the gas and chemical industries. A turbine expander is known, which includes a shaft, turbine and compressor wheels with inlet and outlet cavities, as well as bearing assemblies with supply and drain cavities l. A disadvantage of the known construction is the large lubricant leakage of the bearing assemblies to the gas-jet part of the turbo-expander. The purpose of the invention is to increase the reliability of the turbine expander. This goal is achieved by the fact that the drain cavities of bearing assemblies from the turbine and KOMPVSorny wheels are connected, respectively, with the output chamber of the turbine wheel and the input chamber of the compressor wheel by means of axial channels with radial holes in the shaft. The drawing shows the turbine expander. The turbine expander contains shaft 1, turbine 2 and compressor 3 wheels with inlet 4 and 5 and outlet 6 and 7 cavities, bearing assemblies 8 and 9, inlet 10 and drain 11 cavities, axial channels 12 with air bores 13 and 14 and sealing nodes 1 5. During operation of the expander, the lubricant is supplied to the inlet cavities 10 sealed from the gas flow part by sealing units 15, passes through the bearing units 8 and 9 and enters the drain cavities 11. To reduce leakage of the lubricant, axial channels 12 are made on the gas flow part 1 with radial openings 13 and 14, which together play the role of a lubricant separator.
