Abstract
Изобретение относитс к турбиностро- ению, может быть использовано в турбинах с отборами пара дл тепловых и атомных электростанций и позвол ет повысить экономичность и надежность турбины Отсек паровой турбины содержит диафрагму 5, в теле 6 и ободе 7 которой имеютс кольцевые полости (КП) 8 и 9, сообщающиес между собой пустотелыми лопатками 10 со щел ми 11 на их выпуклой части на 0,20-0,25 высоты лопатки 10 от тела 6 диафрагмы 5 КП 8 и 9 соединены окнами 14 и 15с межлопаточным пространством диафрагмы 5, обод 7 имеет по окружности каналы 16. соедин ющие его кольцевую полость 9 с камерой 1 отбора Площадь каналов 16состороны отвод щего патрубка 2 в 1 5-100 раза меньше чем с противоположной стороны а их обща площадь составл ет 0,7 3,0 площади щели 4 Суммарна площадь окон 1 и щелей 11 больше в 1,6-2,5 раза суммарной площади окон 15 4 з п, ф-лы 3 ил со СThe invention relates to turbine building, can be used in turbines with steam extraction for thermal and nuclear power plants and improves the efficiency and reliability of the turbine. The steam turbine compartment contains a diaphragm 5, in the body 6 and the rim 7 of which there are annular cavities (KP) 8 and 9, interconnected by hollow vanes 10 with slots 11 on their convex part at 0.20-0.25 of the height of the blade 10 from the body 6 of the diaphragm 5 KP 8 and 9 are connected by windows 14 and 15 with the inter-shoulder space of the diaphragm 5, the rim 7 has circumference of the channels 16. connecting its annular cavity 9 with a selection chamber 1 The area of the channels 16 on the side of the outlet nozzle 2 is 1 to 5-100 times smaller than on the opposite side and their total area is 0.7 3.0 slot 4 total area of windows 1 and slots 11 are larger 1.6-2.5 times the total area of windows 15 4 z p, f-ly 3 silt with C
