Description
В основном авт. св. № 79502 описано антикавитационное приспособление дл лопастей рабочих колес гидравлических турбин и насосов, а также и ветродвигателей, выполненное в виде одного или нескольких каналов внутри лопасти, расиоложенны.х в радиальном направленш, соедин ющих между собой область пониженного давлени в месте образовани кавитационных полосте ; (каверн) в тыльной части .юпасти и область повышенного давлеии перед .чопастью. Входные отверсти каналов наход тс на напорной стороне лопасти возможно ближе к ос.;; г ращенн колеса, а выходные отверсти -на спинке лопасти в нескольких местах на разных радиальных рассто ни х от оси вращени колеса. Выходные участки каналов выполн ютс с загибом в сторону, противоположную направлению вращени .Basically auth. St. No. 79502 describes an anti-cavitation device for blades of impellers of hydraulic turbines and pumps, as well as wind turbines, made in the form of one or several channels inside the blade, radially interconnected, connecting the area of reduced pressure at the site of formation of the cavitation cavity; (cavern) in the rear. Judes and the area of hyper pressure in front of the. The inlets of the channels are located on the pressure side of the blade as close as possible to the core ;; the wheels, and the outlets are on the back of the blade in several places at different radial distances from the axis of rotation of the wheel. The output channel portions are bent in the direction opposite to the direction of rotation.
При колесах повышенной быстро.ходности такое ириспособленне не предотвраш.ает вредных последстви кавитации, в результате чего имеют место эрози , вибраци , толчкп, дары и снижение к. п. д.With high-speed wheels, such an adaptation does not prevent the harmful consequences of cavitation, as a result of which there is erosion, vibration, shock, gifts and reduction of efficiency.
В предлагае. антикавитационном приспособлении эти недостатки отсутствуют благодар то.му, что каналы выполнены в виде сплопных полостей. При этом выходна часть каналов может быть вынолнона с наклоном в сторону, противоположную направлению вращени рапочего колеса. Выходна часть каналов .может также иметь двоГшую кривизну и располагатьс во вставных насадках с направлением внешней ветви канала в сторону, противоположн}К) вращению колеса.In the offer. The anti-cavitational device lacks these deficiencies due to the fact that the channels are made in the form of slide cavities. At the same time, the output part of the channels can be made with a slope in the direction opposite to the direction of rotation of the slide wheel. The output part of the channels may also have double curvature and be located in the insertion nozzles with the direction of the outer branch of the channel in the direction opposite to} K) of the wheel.
