JK94—16型16吨数控鱼鳞孔压力机(图1)是加工燃汽轮机“火焰筒”鱼鳞孔的专用机床。“火焰筒”是二万三千千瓦燃汽轮机设备中燃烧室部件的主要易损件之一(见图1中的制件),每台设备中需要十件。因该燃汽轮机是从英国进口的,故“火焰筒”烧损后,只得用大量的外汇向外国购买。 JK94-16 16 tons of CNC fish scale hole presses (Figure 1) is the processing of steam turbine “flame tube” fish scale holes for machine tools. The “flame tube” is one of the major wearing parts of the combustion chamber components of a 23,000-kilowatt gas turbine installation (see the article in Figure 1), ten for each device. Because the gas turbine was imported from the United Kingdom, the burning of the “flame tube” had to be purchased in large quantities by foreign exchange.
