Description
Изобретение относитс к области гидромашиностроени и может быть использовано в направл ющих аппаратах гидромашин, например обратииых . Известныь направл ющие аппара ты гидромашин, содержащие снабженные верхней и нижней цапфами лопат ки с осевым сквозным отверстием, соединенные с рычагами механизма их поворота. В обратимых гидромашинах , особенно при работе в насо сном режиме возникают вибрации лоп паток, вызванные пульсаци ми гидравлического момента, привод щие к усталостным разрушени м цапф ло паток, что снижает надежность гидромашины . Целью изобретени вл етс определение величины, вибрации лопаток в насосном режиме. Дл ЭТОГО в отверстии лопатки размещен упругий элемент, выпол ненный, например, в виде трубки. ОДИН конец которой жестко закреплен на нижней цапфе, а другой уста новлен подвижно относительно лопат ки и соединен с регистрирующим прибором регулирующего органа. Крутильные колебани лопатки вызывают деформацию упругого элемента и в случае повышени вибрации сверх допустимой величины, регистри руемой, например, датчиком, изменют режим работы. На чертеже показан направл ю щий аппарат, продольный разрез. Направл ющий аппарат содержит лопатки I с центральным сквозным отверстием, снабженные верхней 2 и нижней 3 цапфами, и соединенные с рычагами 4 механизма поворота лопаток . В осевом отверстии установлен упругий элемент, например труб ки 5, одним концом жестко соединен на с нижней цапфой 3. Другой конец трубки установлен подвижно относительно лопатки и соединен с изThe invention relates to the field of hydraulic engineering and can be used in guide machines for hydraulic machines, such as formation machines. The known guides of hydraulic machines, containing blades fitted with an upper and lower trunnion with an axial through hole, connected to the levers of the mechanism of their rotation. In reversible hydraulic machines, especially when operating in the pumping mode, vibrations of paddles occur, caused by pulsations of the hydraulic torque, leading to fatigue fractures of the trunnions, which reduces the reliability of the hydraulic machines. The aim of the invention is to determine the magnitude, vibration of the blades in the pump mode. For this, an elastic element is placed in the opening of the blade, for example, in the form of a tube. ONE end of which is rigidly fixed on the lower pin, and the other is mounted movably relative to the blade and is connected to the recording device of the regulator. The torsional vibrations of the blade cause the deformation of the elastic element and in the case of an increase in vibration above the permissible value recorded by, for example, a sensor, change the mode of operation. The drawing shows a guide apparatus, a longitudinal section. The guide vane contains blades I with a central through hole, fitted with an upper 2 and lower 3 trunnions, and connected to the levers 4 of the blades turning mechanism. An elastic element is installed in the axial hole, for example, tube 5, is rigidly connected at one end to the lower trunnion 3. The other end of the tube is movably mounted relative to the blade and is connected to
