Abstract

Изобретение позвол ет повысить надежность гидромашины-при работе в турбинном режиме. Лопасти 3 у станов- лены между втулкой I и нижним ободом 2. Привтулочный выходной участок 4 каждой лопасти выполнен поворотным. При повороте участка 4 уменьшаютс  жгутообразование и низкочастотные колебани  давлени  в потоке и, следовательно , уменьшаютс  вибрации гидромашины . 2 ил.The invention allows to increase the reliability of the hydraulic machine, when operating in the turbine mode. The blades 3 are mounted between the sleeve I and the lower rim 2. The boom output section 4 of each blade is made rotatable. When the section 4 is rotated, the formation of flagella and low-frequency pressure fluctuations in the flow are reduced and, therefore, the vibrations of the hydraulic machine are reduced. 2 Il.

Изобретение относитс  к гидромашиностроению и может быть использовано в рабочих колесах высоконапорных радйально-ойевых гйдромашин. FIELD OF THE INVENTION The invention relates to hydraulic engineering and can be used in impellers of high-pressure radial-oyid hydraulic machines.

Целью изобретени   вл етс  повыше- надежности гидромашины при рабо- TJe в турбинном режиме,The aim of the invention is to improve the reliability of the hydraulic machine during operation of the TJe in the turbine mode,

I На фиг,1 показано рабочее колесо, осевой разрез; на фиг,2 - сечение А-А на фиг,1I FIG. 1 shows the impeller, axial section; FIG. 2 is a section A-A in FIG. 1

Рабочее колесо высоконапорной ра- диально- осевой гидромашины содержит втулку }, нижний обод 2 и установленные между ними, лопасти 3, Привтулоч- выходной участок 4 каждой лопасти выполнен поврротным.The impeller of the high-pressure radial-axial hydraulic machine includes a sleeve}, the lower rim 2 and the blades 3 installed between them, the blade-half-output section 4 of each blade are made rotary.

При работе гидромашины в турбинных режимах, отличных от оптимального,When operating hydraulic machines in turbine modes other than optimal,

привтулочньй выходной участок 4 каждой лопасти 3 поворачивают, что приводит к уменьшению жгутообразовани  и низкочастотных колебаний давлений в потоке и, следовательно, к уменьшению вибрации гидромашины.the sleeve output section 4 of each blade 3 is rotated, which leads to a decrease in the cord formation and low-frequency pressure fluctuations in the flow and, consequently, to a decrease in the vibration of the hydraulic machine.
