Изобретение относитс к модел м рабочих колес гидромашин, например радиально-осевых турбин, и может лай™ применение при их испытании.The invention relates to hydraulic impeller models, such as radial-axial turbines, and may be used when tested.
Известны модели рабочих колес шдромаШИ .НЫ, например радиально-осевых турбин, содержащие лопасти, размещенные между ступицей И ободом.Known models of impellers are shdromsha.NI, for example, radial-axial turbines, containing blades placed between the hub and rim.
Однако такие модели не позвол ют проводить испытани рабочего колеса с измен емым в зоне обода проточным трактом и следовательно выбор оптимальной формы о-бода, обеспечивающей наиболее точно заданную хара-ктеристику турби.ны.However, such models do not allow testing of the impeller with a flow path changing in the rim area and, therefore, the choice of the optimal shape of the baud providing the most precisely defined characteristics of the turbine.
Цель предлагаемого изобретени - обеспечение возможности иопыта,ний колеса с различной формой проточного тракта.The purpose of the invention is to provide opportunities for the development of a wheel with a different shape of the flow path.
Это достигаетс тем, что обод выполнен разъемным из жестко соединенной с лопаст ми .нижней части и .выполненной в виде разрезного кольца верхней части.This is achieved by the fact that the rim is made of a detachable one rigidly connected to the blades of the lower part and the upper part formed as a split ring.
На чертеже изображена предлагаема модель рабочего колеса в разрезе.The drawing shows the proposed model of the impeller in the section.
Рабочее колесо содержит ступицу 1, посто нную -нижнюю часть 3 обода, которые жестко соединены лопаст ми 3 и выполненную в виде разрезного кольца сменную верхнюю часть 4 обода, прикрепленную .к посто нной части обода винтами 5. Возможную щель между лопаст ми и сменной частью обода замазывают, например, пластилином.The impeller contains a hub 1, a constant-lower part 3 of the rim, which are rigidly connected by blades 3 and an interchangeable upper part 4 of the rim, made in the form of a split ring, attached to the fixed part of the rim by screws 5. Possible gap rims are covered, for example, with clay.
Име набор сменных полуколец с различпым профилем проточной части можно провести обширный объем испытаний с вы влением оптимальной формы обода.Having a set of replaceable half-rings with a razlipy profile of the flow part, it is possible to conduct an extensive amount of tests with the identification of the optimal shape of the rim.
