Abstract
Изобретение относитс к измерению зазоров и может быть использовано при проведении испытаний турбомашины. Цель - повышение точности измерени зазора при неподвижном роторе за счет преобразовани емкости, завис щей от величины зазора, в амплитуду напр жени . В устройстве использован емкостный датчик 1 в виде пластины, изолированной от корпуса турбомашины, устанавливаемый перпендикул рно радиусу зазора, который образует емкость с торцом лопатки 9. Эта емкость зар жаетс от источника 2 напр жени через ключ 4 и подключаетс через ключ 5 к входу интегратора 6, который преобразует зар д на емкости датчика 1 в выходное напр жение, пропорциональное величине зазора. 3 ил.The invention relates to the measurement of clearances and can be used when testing a turbomachine. The goal is to improve the accuracy of measuring the gap while the rotor is stationary by converting the capacitance, depending on the size of the gap, into voltage amplitude. The device uses a capacitive sensor 1 in the form of a plate, isolated from the turbomachine body, mounted perpendicular to the radius of the gap, which forms a container with the end of the blade 9. This capacity is charged from the voltage source 2 through the switch 4 and connected via the switch 5 to the integrator 6 input which converts the charge on the capacitance of the sensor 1 to an output voltage proportional to the size of the gap. 3 il.
