Abstract
Способ определения радиального зазора между торцами лопаток вращающегося ротора и корпусом турбомашины, заключающийся в том, что регистрируют с помощью эндоскопа значения величин изображений зазора у ближней к эндоскопу кромки лопатки при неподвижном и вращающемся роторе, отличающийся тем, что, с целью повышения точности определения, регистрируют значения величин изображений зазора у дальней от эндоскопа кромки лопатки при неподвижном и вращающемся роторе и определяют значение радиального зазора по формулегде δи δ - величины радиального зазора при неподвижном и вращающемся роторе соответственно;- величины изображений зазора у дальней и ближней от эндоскопа кромок лопатки соответственно при неподвижном роторе;mи m- то же, но при вращающемся роторе.The method for determining the radial clearance between the ends of the blades of the rotating rotor and the turbomachine body, consists in recording with the help of an endoscope the values of the image values of the gap at the blade edge closest to the endoscope with a fixed and rotating rotor, characterized in that, in order to improve the accuracy of determination, the values of the image of the gap at the edge of the blade farthest from the endoscope with a stationary and rotating rotor and determine the value of the radial clearance by the formulas δ and δ are the radial values th clearance with stationary and rotating rotor, respectively; - the gap in the image of the near and far edges of the blade respectively endoscope when the rotor is stationary; MI m- same, but with a rotating rotor.
