Application of aerospace brazing furnace
The Pratt & Whitney JT9D engine honeycomb seal ring, the ring and the honeycomb sandwich made by vacuum brazing; the engine fuel manifold by authority and a number of branch pipe, nozzle made of vacuum brazing stainless steel heat exchanger; this engine consists of 300 stainless steel tube, a plurality of partitions, casing for vacuum brazing; JT8D engine the 12 and 13 stage compressor stator ring by the outer ring and the blade made of dozens of vacuum brazing. The GE engine casing of the United States is made up of more than 240 0.25 to 0.7mm thick nickel alloy parts subjected to three steps vacuum brazing. China, Shenyang Motor Company and Chengdu engine company are vacuum brazing stator ring for naval aircraft engine company; Chengdu vacuum brazing fuel manifold, and the engine test.
Vacuum brazing furnace is the main brazing equipment in Aeroengine manufacturing. There are more than 200 vacuum brazing furnaces in the United states. Domestically, Liming Engine Manufacturing Company, Chengdu engine company and Beijing Aeronautical Technology Research Institute developed vacuum brazing electric furnace for medium-sized single room in 70s. Beijing Aeronautical Manufacturing Technology Research Institute in 1964 with the Tianjin Electric Furnace Factory Co developed semi continuous vacuum brazing furnace, Xi’an aviation engine company introduced Ipsen company (horizontal vacuum furnace furnace size 910 * 610 * 610mm), Beijing civil aviation company Ameco’s introduction of Ipsen bell vacuum brazing furnace (furnace size k 2300 * 1300mm). The imported stove are microcomputer temperature control, automatic program control. Now, Shenyang Institute of vacuum technology, Beijing Institute of Aeronautical Technology, Shenyang Institute of vacuum applications and other units have developed a microcomputer temperature control, automatic controlled by the program of large high temperature vacuum brazing furnace.
