Description

(54) СПОСОБ КОНТГОЛЯ ОХЛАЖДАЮЩИХ КАНАЛОВ ЛОПАТКИ ТУРБИНЫ(54) METHOD FOR CONTAINING COOLING CHANNELS OF TURBINE SHEET

.Изобретение относитс  к энергетическо1и7 .машиностроению и может быть использовано при производстве газовых турбин.The invention relates to power generation and machine building and can be used in the manufacture of gas turbines.

Известен способ контрол  охлаждающих каналов лопатки турбины путем определени  температурного пол  лопатки и сравнени  его с эталонным 1.A known method of controlling the cooling channels of a turbine blade by determining the temperature field of the blade and comparing it with a reference one.

Однако при указанном способе контрол  необходима операци  установки термопар на лопатку, св занна  с разрушением ее поверхностного сло  и значительными затратами времени, что усложн ет контроль.However, with this control method, the installation of thermocouples on the blade is necessary, which is associated with the destruction of its surface layer and a considerable amount of time, which complicates the control.

Наиболее близким к изобретению  вл етс  способ контрол  охлаждающих каналов лопатки турбины путем продувки их нагретым воздухом, определени  температурного пол  лопатки и сравнени  его с эталонным 2.Closest to the invention is a method for monitoring the cooling channels of a turbine blade by blowing it out with heated air, determining the temperature field of the blade and comparing it with a reference 2.

Однако при известном способе контрол  необходимо измерение  ркостной температуры .лопатки путем сравнени  интенсивности излучени  волн определенной длины измер емого тела и регулируемого источника света, температура которого известна, что усложн ет контроль.However, with the known method of control, it is necessary to measure the lightness temperature of the blade by comparing the intensity of radiation of waves of a certain length of the body being measured and an adjustable light source whose temperature is known, which complicates the control.

Целью изобретени   вл етс  упрощение контрол .The aim of the invention is to simplify the control.

Указанна  цель достигаетс  тем, что лопатку обжимают эластичной пластиной, продувку каналов ведут до установлени  на границе лопатка-пластина стационарного теплового режима, а определение температурного по ,Q л  лопатки осуществл ют измерением тем пературы пластийы в развернутом состо нии. На фиг. 1 изображен частичный поперечный разрез установки дл  реализации описьшаемого способа с закрепленной на ней лопаткой; J5 на фиг. 2 - приспособление дл  измерени  температуры пластины в развернутом состо нии, поперечный разрез.This goal is achieved by the fact that the blade is crimped with an elastic plate, the channels are blown up until a stationary thermal regime is established at the blade-plate boundary, and the determination of the temperature, QL blade is carried out by measuring the temperature of the plastics in the unfolded state. FIG. 1 shows a partial cross section of an installation for implementing the described method with a blade attached thereto; J5 in FIG. 2 shows a device for measuring the temperature of a plate in an unfolded state, a transverse section.

Установка содержит контролируемую лопатку 1 с охлаждающими каналами 2-4, элас20 тнчную пластину 5, прижимные термопары 6, ложемент 7.The installation contains a controlled blade 1 with cooling channels 2-4, elas20 tnchnuyu plate 5, clamping thermocouples 6, lodgement 7.

Контролируем)) лопатку 1 обжимают эластичной пластиной 5, продувку охлаждающих каналов 2-4 ведут до установлени  на граWe control)) the blade 1 is compressed by an elastic plate 5, the cooling channels 2-4 are blown down to
