Description

В известных способах измерени  площади сечени  проточной части сопловых отверстий турбин используетс  механическа  или электромеханическа  передача.In the known methods of measuring the cross-sectional area of the flow part of the turbine nozzle holes, mechanical or electromechanical transmission is used.

Описываемый способ отличаетс  тем, что в нем измерение осун.1,ествл етс  при помощи гидравлического прибора с несколькими измерительными наконечниками. Гидравлическа  система служит дл  измерени  перемещений наконечников и суммировани  их в уровиемерной трубке по щкаЛе, градуированной в единицах площади. Такой способ повышает точность измерений.The described method is characterized by the fact that in it the measurement of the base pipe 1 is tested using a hydraulic device with several measuring tips. The hydraulic system serves to measure the displacements of the tips and sum them in a leveling tube along the bar, graduated in units of area. This method improves the accuracy of measurements.

На чертеже показан прибор дл  осуществлени  предлагаемого способа .The drawing shows a device for carrying out the proposed method.

Прибор включает в себ  следующие основные детали: корпус / резиновую диафрагму 2, измерительные наконечники ., нанравл ющие планки 4, штуцер 5, стекл нную трубку 6, упорные планки 7, металлическую трубку 5, щкалу 9, мерные планки Ю, винт // перемещени  щкаль, неподвижный упор 12, компенсатор 13.The device includes the following main parts: body / rubber diaphragm 2, measuring tips., Arrays 4, fitting 5, glass tube 6, stop bars 7, metal tube 5, shchalu 9, measuring bars U, screw // displacement shkal, fixed stop 12, the compensator 13.

При измерении прибор устанавливают упорными планками 7 по выходной кромке лопатки и прижимают к внутреннему кольцу соплового аппарата неподвижным упором 12. При повороте прибора относительно выходной кромки лопатки измерительные наконечники 3, скольз  по спинке нижней лопатки и по наружному кольцу соплового аппарата, перемещаютс  в направл ющих планках и прогибают резиновую диафрагму 2. Конструкци  прибора выполнена так, что жидкость, вытесн ема  всеми наконечниками, проходит по каналу к штуцеру 5 и попадает в одну общую стекл нную трубку 6. Максимальный уровень жидкости в стекл нной трубке соответствует максимальному перемещению наконечников , а следовательно, минимальной площади- Возврат наконечников вWhen measuring, the device is installed by the stop plates 7 along the output edge of the blade and pressed against the inner ring of the nozzle apparatus with a fixed stop 12. When the instrument rotates relative to the exit edge of the blade, the measuring tips 3 slide along the back of the lower blade and the outer ring of the nozzle apparatus in the guide bars and bend the rubber diaphragm 2. The design of the device is made so that the fluid, displaced by all tips, passes through the channel to the fitting 5 and falls into one common glass tube. BUD 6. The maximum level of liquid in glass tube corresponds to the maximum tip displacement and, consequently, the minimum return lugs in ploschadi-
