Abstract
Изобретение позвол ет снизить металлоемкость стенда. Стенд содержит гидротурбину 1, вакуумный бак 2, всасывающий трубопровод 3, питательный насос 4, напорный водовод 5, напорный бак 6 с дренажным краном 7 и герметичную емкость (Е) 8. Верхн часть Е 8 подключена к верхней части вакуумного бака 2 при помощи трубопровода 9 с дренажным краном 10, а к ее нижней части подсоединен трубопровод 11 с дросселем 12. Размещение Е 8 над вакуумным баком 2 и подсоединение к нему трубопровода 11 позвол ют уменьшить размеры Е 8 и тем самым снизить металлоемкость стенда. 1 ил.The invention allows to reduce the metal content of the stand. The stand contains a hydro turbine 1, a vacuum tank 2, a suction pipe 3, a feed pump 4, a discharge conduit 5, a pressure tank 6 with a drain valve 7 and a sealed container (E) 8. The upper part of E 8 is connected to the upper part of the vacuum tank 2 by means of a pipeline 9 with a drain valve 10, and a pipe 11 with a throttle 12 is connected to its lower part. Placing the E 8 above the vacuum tank 2 and connecting the pipe 11 to it will reduce the size of the E 8 and thereby reduce the metal intensity of the stand. 1 il.
Description
,Изобретение относится к гидроэнергетике и может быть использовано в стендах для кавитационных исследований гидротурбин., The invention relates to hydropower and can be used in stands for cavitation research of hydraulic turbines.
Целью изобретения является снижение металлоемкости стенда.The aim of the invention is to reduce the intensity of the stand.
На чертеже показана схема стенда. Стенд для кавитационных исследований гидротурбин содержит заполненный ю жидкостью замкнутый контур, включающий последовательно установленные гидротурбину 1, вакуумный бак 2, всасывающир трубопровод 3, питательный насос 4,| напорный водовод 5 и напорный бак 15 6 с дренажным краном 7, и герметичную емкость 8, верхняя часть которой подключена к верхней части вакуумного бака 2 при помощи трубопровода 9 с дренажным краном 10, а к ее нижней 20 части подсоединен трубопровод 11с дросселем 12. Герметичная емкость 8 размещена над вакуумным баком 2, а трубопровод 11 с дросселем 12 дополнительно подключен к вакуумному баку 2. 25 I При работе стенда уменьшение давления в вакуумном баке 2 осуществля ется путем слива части воды из герметичной емкости 8 через трубопровод 11 вакуумный бак 2 и одновременно через^о дренажный кран 7 из напорного бака 6. При этом обеспечивается постоянство уровня воды в вакуумном баке 2. Размещение герметичной емкости 8 над вакуумным баком 2 и подсоединение к нему трубопровода 11 позволяет уменьшить размеры герметичной емкости и тем самым снизить металлоемкость стенда.The drawing shows a diagram of the stand. The stand for cavitation research of hydraulic turbines contains a closed loop filled with liquid, including a series-mounted hydraulic turbine 1, a vacuum tank 2, a suction pipe 3, a feed pump 4, | pressure pipe 5 and pressure tank 15 6 with a drain valve 7, and a sealed container 8, the upper part of which is connected to the upper part of the vacuum tank 2 using a pipe 9 with a drain valve 10, and a pipe 11 with a throttle 12 is connected to its lower 20 part. a container 8 is placed above the vacuum tank 2, and the pipe 11 with the choke 12 is additionally connected to the vacuum tank 2. 25 I When the stand is working, the pressure in the vacuum tank 2 is reduced by draining part of the water from the sealed container 8 through the pipe 11, the vacuum tank 2 and at the same time through a drainage valve 7 from the pressure tank 6. This ensures that the water level in the vacuum tank 2 is constant. Placing the sealed container 8 above the vacuum tank 2 and connecting the pipe 11 to it reduces the size of the sealed container and thereby reduce the metal consumption of the stand.
