Description
(54) МОДЕЛЬ ГИДРОМАШИНЫ(54) HYDRAULIC MODEL
Изобретение относитс к гидромашиностроению и может быть использовано при модельных исследовани х гидромашины.The invention relates to hydraulic machine building and can be used in model studies of a hydraulic machine.
Известны модели гидромашин, содержашие рабочее колесо, установленное на валу, и индуктивный тормоз, опираюпдийс на подп тник , имеюший кольцевую месдозу, св занную с трубопроводом 1.Hydraulic machine models are known that contain an impeller mounted on a shaft and an inductive brake supported on a stopper having an annular space associated with pipeline 1.
Однако в таких модел х снижаетс точность измерени осевого усили при изменении размерности испытываемого рабочего колеса.However, in such models, the accuracy of the axial force measurement decreases with changing dimensions of the impeller under test.
Целью изобретени вл етс повышение точности измерений при испытани х.The aim of the invention is to improve the measurement accuracy during testing.
Дл этого в подп тнике модели выполнены кольцевые полости, расположенные концентрично месдозе и св занные с автономными трубопроводами, и на всех трубопроводах установлены трехходовые краны.To do this, annular cavities are made in the model's bushing, which are located concentric to the center and connected with autonomous pipelines, and three-way valves are installed on all pipelines.
На чертеже схематически изображена модель гидромашины, продольный разрез.The drawing shows schematically the model of the hydraulic machine, a longitudinal section.
Модель гидромашины содержит рабочее колесо 1, установленное на валу 2, и индуктивный тормоз 3, опираюшийс на подп тник 4, имеюший кольцевую месдозу 5, св занную с трубопроводом 6.The hydraulic machine model contains an impeller 1 mounted on the shaft 2 and an inductive brake 3 supported on the pad 4 having an annular space 5 connected to the pipeline 6.
В подп тнике 4 выполнены кольцевые полости 7 и 8, расположенные концентрично месдозе 5 и св занные с автономными трубопроводами 9 и 10. На всех трубопроводах 6, 9 и 10 установлены трехходовые краны 11, 12 и 13. Ring 4 is provided with annular cavities 7 and 8 located concentric with the center 5 and connected with autonomous pipelines 9 and 10. Three-way valves 11, 12 and 13 are installed on all pipes 6, 9 and 10.
Модель гидромашины работает при испытании следуюши.м образом.The hydraulic machine model works by testing in the following way.
При помош,и трехходовых кранов 11, 12 и 13 через автономные трубопроводы 6, 9 и 10 избирательно подключают каждую кольцевую полость 7 и 8 и месдозу 5 к напорной или сливной магистрали. Тем самым измен ют величину давлени жидкости в кольцевых полост х и месдозе, поскольку в данной модели эта величина зависит не только от осевой силы, создаваемой рабочим колесом 1, но и от плошади тех кольцевых полостей подп тника, которые соединены через трехходовые краны с напорной магистралью . При этом уровень давлени всегда можно подобрать таким, чтобы точность измерени прибора была наивысшей.With the help, and the three-way valves 11, 12 and 13, through independent pipes 6, 9 and 10, each annular cavity 7 and 8 and the space-dose 5 are selectively connected to the pressure or drain line. Thus, the magnitude of the pressure of the fluid in the annular cavities and mesdoses is changed, since in this model this value depends not only on the axial force generated by the impeller 1, but also on the area of those annular cavities of the subcapital connected to the pressure line . In this case, the pressure level can always be chosen so that the measurement accuracy of the device is the highest.
