Уплотнение вращающегося регенеративного теплообменника относится к уплотнительной технике, преимущественно газотурбинных двигателей. Уплотнение расположено в корпусе, содержит установленную между теплообменником и корпусом жесткую рамку, составленную из выполненных раздельно кольцевой и радиальной частей. В пазах рамки расположены подпружиненные уплотнительные башмаки из антифрикционного материала. Стык между корпусом и рамкой уплотнен термобарьерной прокладкой. Сопряжение частей рамки между собой выполнено в местах их примыкания друг к другу по плоским площадкам, ориентированным нормально к теплообменнику и параллельно продольной оси радиальной части. Сопряжение уплотнено подпружиненными плоскими вкладышами из антифрикционного материала. Устройство позволяет повысить эффективность уплотнения за счет уменьшения общего коробления рамки при неравномерном поле температур в последней.The seal of the rotating regenerative heat exchanger relates to sealing technology, mainly gas turbine engines. The seal is located in the housing, contains a rigid frame installed between the heat exchanger and the housing, composed of separately made annular and radial parts. In the frame grooves there are spring-loaded sealing shoes made of antifriction material. The joint between the housing and the frame is sealed with a thermal barrier gasket. The interfacing of the frame parts with each other is performed at the points of their junction to each other along flat surfaces oriented normally to the heat exchanger and parallel to the longitudinal axis of the radial part. The mate is sealed with spring-loaded flat liners of antifriction material. The device allows to increase the efficiency of compaction by reducing the total distortion of the frame with an uneven temperature field in the latter.
