Description

Кавитациоиные свойства гидротурбин до сих пор определ лись путем кавитационных испытаний моделей гидротурбин. Однако получаемые при испытании модели характеристики не соответствуют точно характеристикам натурных гидротурбин.The cavitational properties of hydroturbines have so far been determined by cavitation tests of hydroturbine models. However, the characteristics obtained when testing a model do not correspond exactly to the characteristics of natural hydraulic turbines.

Описываемый способ ;натурных кавитационных испытаний гидротурбин дает возможность производить эти испытани  непосредственно на гидроэлектростанци х. Он состоит в том, что, с целью создани  дополнительного вакуума в отсасывающей трубе гидротурбины, устье отсасывающей трубы герметически закрываетс  коробом с насосами дл  принудительной откачки воды, проход щей через турбину.The described method; full-scale cavitation testing of hydro turbines makes it possible to carry out these tests directly on hydroelectric power plants. It consists in the fact that, in order to create an additional vacuum in the suction pipe of the turbine, the mouth of the suction pipe is hermetically closed by a box with pumps for forcibly pumping out the water passing through the turbine.

На .фиг. изображена кавитационного испытани  гидротурбины описываемым способом.On .fig. shows a cavitation test of a hydro turbine by the described method.

Устье отсасывающей трубы / турбины 2 герметически закрывают коробом 3 с вход щим в его заднюю часть патрубком 4 насоса дл  принудительной откачки воды. Дл  выравнивани  потока воды в начале короба 5 перед патрубком 4 устанавливают решетку 5 из вертикальных труб. Регулиру  тем или иным cnoco6o.vi производительность насоса принудительной откачки воды из короба 3, можно в широких пределах мен ть напор турбины 2 и давление в отсасывающей трубе / и, тем самым , определ ть кавитационные свойства гидротурбины в различных услови х ее работы.The mouth of the suction pipe / turbine 2 is hermetically sealed with a box 3 with a pump nozzle 4 entering its rear part for forcibly pumping out water. To equalize the flow of water at the beginning of the duct 5, in front of the nozzle 4, a grid 5 of vertical pipes is installed. By adjusting one or another cnoco6o.vi capacity of the pump for forcibly pumping water from box 3, it is possible to change the pressure of the turbine 2 and the pressure in the suction pipe /, and thus determine the cavitation properties of the turbine in various conditions of its operation.
